Here is the ChangeLog + for that: + + March/April 1995 + + * pushd/popd changes from Anthony Heading <aheading@jpmorgan.com> + + * fignore fixes from Sven + + * where builtin from Zefram (5901) + manual from me. + + * New glob qualifiers from Zefram (5918) + + * &| backgrounding from Zefram (5919) with some manual changes + from me + + * New option, -m to print + + * New option, -U to typeset to remove duplications from an array + + * Swap -f and -F on the command line if zsh is invoked as sh/ksh. + + * KSH_ARRAYS option + + * array subscripts can be really used without leading $ in math + + * if a parameter is used in math its value is evaluated with full + arithmetic evaluation. + + * # can be used in mathematical expressions as described in the + manual. + + * new parameter TTYIDLE containing the idle time of the current + tty in seconds + + * new parameter ZSHNAME to tell how zsh is invoked + + * lots of bugfixes in params.c + + * If SIGALRM is not trapped zsh will only exit on alarm if + TTYIDLE >= TMOUT. If TTYIDLE < TMOUT a new alarm is set to + TMOUT - TTYIDLE seconds. No change in behaviour when SIGALRM + is trapped. + + * $#foo when foo is an array returns the array length in double + quotes + + * $=foo and ${(s:...:)foo} forces splitting even in double quotes + + * New flags to paramer substitution: @, A, e, p, f, F, W + + * autoremoveslash if a slash is typed + + * fix bugs related to menu completion and expand-or-complete-prefix + + * cshjunkiequotes fixed to really emulate csh behaviour. So far + backslash newline was removed in double- and backquotes but csh + removes the backslash only. + + * the $, # and ? special parameters can bee used without the + leading $ in math + + * negative sign is printed before the base in convbase + (-2#111 instead of 2#-111) + + * > <(foo) and < >(foo) redirections are now cause parse error + + * < <(foo) fixed (it did not work so far). + + * fixed a bug when history were expanded on cat <\!foo + + * history expansion is disabled in single quotes within double + quotes: echo "`echo '!$'`" prints !$. It is not yet perfect but + not worse than in bash since history expansion is also disabled + in `echo "'!$'"`. + + * echo $(echo \!$) no longer expands history. This sometimes + caused infinite memory eating loops in earlier verions. + + * history bangchars are only escaped in the history if they were + originally escaped on the command line. + + * $((...)) math evaluation is done before fork now which makes + assignment and increment/decrement operators work. Now all + substitutions are done before fork exept globbing. To reflect + this change I removed postfork() from subst.c and replaced with + globlist(). + + * The shell behaviour is slightly changed when the globsubst + option is set. Now globsubst is really globsubst, ie. only + tidle and equals substitution and globbing is done on the + result of parameter expansion and command substitution which + makes it more sh-compatible. It means that foo='$bar' ; echo + $foo no longer prints the value of bar. It also prevents + infinite uninterruptable loops like foo='$foo' ; echo $foo. + Also globsubst no longer removes single and double quotes from + the value of parameters and a backshlash is only removed if it + followed by a glob special character or a backslash. The result + of command substitution is handled the same way. These are + really done by tokenize() in glob.c. This function must not be + used to tokenize a string before singsub(). We have to use the + lexer for that. I provided a parsestr() function for that which + parses a given string as it were a string within double quotes + (but it may contain double quotes). + + * Expansion does not starts again on each expanded parameter + which should make it a little faster. With rcexpandparam set + the part of the line following the array evaluated only + once. This makes it a little bit faster but it may cause + problems when the tail of the line has an arithmetic expression + with a side effect: $foo$[i++] increments i by one but in old + versions i was incremented by the number of array elements. If + foo is an empty array i is not changed in either versions. + + * Parsing of mathematical substitutions are now done like double + quoted strings. The body of a math substiturion is first + expanded using parameter, command and arithmetic substitution + and only the result is evaluated. This means that modifyers, + backquote substitution and ${foo##$bar} type expansions can be + used. This makes ((...)), $((...)) and $[...] completely + equivalent. + + * If $@ is empty ''$@ and $@"" and similar arguments are not + removed. The argument is only removed from the argument list if + it is written as "$@" (or if rcexpandparam is set). + + * zatol() function is removed + + * doexpandhist() (ie. magic-space) now keeps the cursor in the + right palace in all cases I hope. + + * lexer fixes to help completion and to fix parsing problems in + brace-params (things like ${foo:-()} and ${foo:-|} used to give + a parse error but ${foo:-(}) didn't.) + + * get_comp_string completely rewritten + + Wed Apr 12 1995 + + * I changed the lexer to allow `]' characters in [...] glob + list. This is to make zsh compatible with all other shells I + know. This should be documented in the manual where the + description of [a-z] syntax is also missing. I'd copy the + relevant part from an other manual page but there may be + copyright problems with that. I looked at some man pages but + they contained almost word-by-word the same so I think we can + do that as well (change some words perhaps). + + * There are some important changes in the new substitution code. + The right hand side of parameter assignments is no longer + globbed by default (note that tidle and equals substitution is + not globbing). This is compatible with sh/ksh/bash. I added an + option, GLOB_ASSIGN which can be set to restore the old + behaviour but I do not recommend the usage of this option. For + more details, see the manual. If GLOB_ASSIGN is not set, it is + guaranteed that foo=... assignments assign a scalar value. In + earlier versions foo=* or foo=$bar where bar is an array + created scalars if the result had zero or one words and an + array otherwise. + + Thu Apr 13 1995 + + * prompts are empty if the shell is not interactive from + P.Stephenson (5836) + + * pwd -r prints the real path + + * emulate builtin + + * ! and bangchar quoting fixed. + + * echo { prints { when ignorebraces is set + + * completion works correctly with COMPLETE_ALIASES + + Tue Apr 18 1995 + + * i/o not redirected to /dev/null in <(...) and >(...) (both in + redirections and in arguments). + + Wed Apr 19 1995 + + * ${$(...)...} syntax can be used + + Sat Apr 29 1995 + + * zle history expansion was buggy when a word begun with a #. + It's fixed. + + * prompt substitution is now completely functional (things like + ${...##...} or `...` are usable now in prompts) + + Fri May 5 1995 + + * USERNAME, LOGNAME, HOST, TTY and signals are no longer specials + parameters.

For example, + +nofill(tt(compctl -k "(cputime filesize datasize stacksize + coredumpsize resident descriptors)" limit)) +) +item(tt(-g) var(globstring))( +The var(globstring) is expanded using filename globbing; it should be +quoted to protect it from immediate expansion. The resulting +filenames are taken as the possible completions. Use `tt(*(/))' instead of +`tt(*/)' for directories. The tt(fignore) special parameter is not +applied to the resulting files. More than one pattern may be given +separated by blanks. (Note that brace expansion is em(not) part of +globbing. Use the syntax `tt((either|or))' to match alternatives.) +) +item(tt(-s) var(subststring))( +The var(subststring) is split into words and these words are than +expanded using all shell expansion mechanisms (see +ifzman(zmanref(zshexpn))\ +ifnzman(noderef(Expansion))\ +). The resulting words are taken as possible +completions. The tt(fignore) special parameter is not applied to the +resulting files. Note that tt(-g) is faster for filenames. +) +item(tt(-K) var(function))( +Call the given function to get the completions. The function is +passed two arguments: the prefix and the suffix of the word on which +completion is to be attempted, in other words those characters before +the cursor position, and those from the cursor position onwards. The +whole command line can be accessed with the tt(-c) and tt(-l) flags +of the tt(read) builtin. The +function should set the variable tt(reply) to an array containing +the completions (one completion per element); note that tt(reply) +should not be made local to the function. From such a function the +command line can be accessed with the tt(-c) and tt(-l) flags to +the tt(read) builtin. For example, + +nofill(tt(function whoson { reply=(`users`); } +compctl -K whoson talk)) + +completes only logged-on users after `tt(talk)'. Note that `tt(whoson)' must +return an array, so `tt(reply=`users`)' would be incorrect. +) +item(tt(-H) var(num pattern))( +The possible completions are taken from the last var(num) history +lines. Only words matching var(pattern) are taken. If var(num) is +zero or negative the whole history is searched and if var(pattern) is +the empty string all words are taken (as with `tt(*)'). A typical +use is + +nofill(tt(compctl -D -f PLUS() -H 0 '')) + +which forces completion to look back in the history list for a word if +no filename matches. +) +enditem() +texinode(Control Flags)()(Flags with Arguments)(Option Flags) +subsect(Control Flags) +These do not directly specify types of name to be completed, but +manipulate the options that do: + +startitem() +item(tt(-Q))( +This instructs the shell not to quote any metacharacters in the possible +completions. Normally the results of a completion are inserted into +the command line with any metacharacters quoted so that they are +interpreted as normal characters. This is appropriate for filenames +and ordinary strings. However, for special effects, such as inserting +a backquoted expression from a completion array (tt(-k)) so that +the expression will not be evaluated until the complete line is +executed, this option must be used. +) +item(tt(-P) var(prefix))( +The var(prefix) is inserted just before the completed string; any +initial part already typed will be completed and the whole var(prefix) +ignored for completion purposes. For example, + +nofill(tt(compctl -j -P "%" kill)) + +inserts a `%' after the kill command and then completes job names. +) +item(tt(-S) var(suffix))( +When a completion is found the var(suffix) is inserted after +the completed string. In the case of menu completion the suffix is +inserted immediately, but it is still possible to cycle through the +list of completions by repeatedly hitting the same key. +) +item(tt(-W) var(file-prefix))( +With directory var(file-prefix): for command, file, directory and +globbing completion (options tt(-c), tt(-f), tt(-/), tt(-g)), the file +prefix is implicitly added in front of the completion. For example, + +nofill(tt(compctl -/ -W ~/Mail maildirs)) + +completes any subdirectories to any depth beneath the directory +tt(~/Mail), although that prefix does not appear on the command line. +) +item(tt(-q))( +If used with a suffix as specified by the tt(-S) option, this +causes the suffix to be removed if the next character typed is a blank +or does not insert anything (the same rule as used for the +tt(AUTO_REMOVE_SLASH) option). The option is most useful for list +separators (comma, colon, etc.). +) +item(tt(-l) var(cmd))( +This option cannot be combined with any other. It restricts the range +of command line words that are considered to be arguments. If +combined with one of the extended completion patterns `tt(p[)...tt(])', +`tt(r[)...tt(])', or `tt(R[)...tt(])' (see noderef(Extended Completion) +below) the range is restricted to the range of arguments +specified in the brackets. Completion is then performed as if these +had been given as arguments to the var(cmd) supplied with the +option. If the var(cmd) string is empty the first word in the range +is instead taken as the command name, and command name completion +performed on the first word in the range. For example, + +nofill(tt(compctl -x 'r[-exec,;]' -l '' -- find)) + +completes arguments between `tt(-exec)' and the following `tt(;)' (or the end +of the command line if there is no such string) as if they were +a separate command line. +) +item(tt(-U))( +Use the whole list of possible completions, whether or not they +actually match the word on the command line. The word typed so far +will be deleted. This is most useful with a function (given by the +tt(-K) option) which can examine the word components passed to it +(or via the tt(read) builtin's tt(-c) and tt(-l) flags) and +use its own criteria to decide what matches. If there is no +completion, the original word is retained. +) +item(tt(-y) var(func-or-var))( +The list provided by var(func-or-var) is displayed instead of the list +of completions whenever a listing is required; the actual completions +to be inserted are not affected. It can be provided in two +ways. Firstly, if var(func-or-var) begins with a tt($) it defines a +variable, or if it begins with a left parenthesis a literal +array, which contains the list. A variable may have been set by a +call to a function using the tt(-K) option. Otherwise it contains the +name of a function which will be executed to create the list. The +function will be passed as an argument list all matching completions, +including prefixes and suffixes expanded in full, and should set the +array var(reply) to the result. In both cases, the display list will +only be retrieved after a complete list of matches has been created. + +Note that the returned list does not have to correspond, even in +length, to the original set of matches, and may be passed as a scalar +instead of an array. No special formatting of characters is +performed on the output in this case; in particular, newlines are +printed literally and if they appear output in columns is suppressed. +) +item(tt(-X) var(explanation))( +Print var(explanation) when trying completion on the current set of +options. A `tt(%n)' in this string is replaced by the number of matches. +The explanation only appears if completion was tried and there was +no unique match, or when listing completions. +) +item(tt(-Y) var(explanation))( +Identical to tt(-X), except that the var(explanation) first undergoes +expansion following the usual rules for strings in double quotes. +The expansion will be carried out after any functions are called for +the tt(-K) or tt(-y) options, allowing them to set variables. +) +enditem() +texinode(Alternative Completion)(Extended Completion)(Option Flags)(Programmable Completion) +sect(Alternative Completion) +startlist() +list(tt(compctl) [ tt(-CDT) ] var(options) tt(PLUS()) var(options) [ tt(PLUS()) ... ] \ +[ tt(PLUS()) ] var(command) ...) +endlist() + +The form with `tt(PLUS())' specifies alternative options.

Each var(pattern) is examined in turn; when a +match is found, the corresponding var(options), as described in +noderef(Option Flags) above, are used to generate possible +completions. If no var(pattern) matches, the var(options) given +before the tt(-x) are used. + +Note that each pattern should be supplied as a single argument and +should be quoted to prevent expansion of metacharacters by the +shell. + +A var(pattern) is built of sub-patterns separated by commas; it +matches if at least one of these sub-patterns matches (they are +`or'ed). These sub-patterns are in turn composed of other +sub-patterns separated by white spaces which match if all of the +sub-patterns match (they are `and'ed). An element of the +sub-patterns is of the form `var(c)tt([)...tt(][)...tt(])', where the pairs of +brackets may be repeated as often as necessary, and matches if any of +the sets of brackets match (an `or'). The example below makes this +clearer. + +The elements may be any of the following: + +startitem() +item(tt(s[)var(string)tt(])...)( +Matches if the current word on the command line starts with +one of the strings given in brackets. The var(string) is not removed +and is not part of the completion. +) +item(tt(S[)var(string)tt(])...)( +Like tt(s[)var(string)tt(]) except that the var(string) is part of the +completion. +) +item(tt(p[)var(from)tt(,)var(to)tt(])...)( +Matches if the number of the current word is between one of +the var(from) and var(to) pairs inclusive. The comma and var(to) +are optional; var(to) defaults to the same value as var(from). The +numbers may be negative: tt(-)var(n) refers to the var(n)'th last word +on the line. +) +item(tt(c[)var(offset)tt(,)var(string)tt(])...)( +Matches if the var(string) matches the word offset by +var(offset) from the current word position. Usually var(offset) +will be negative. +) +item(tt(C[)var(offset)tt(,)var(pattern)tt(])...)( +Like tt(c) but using pattern matching instead. +) +item(tt(w[)var(index)tt(,)var(string)tt(])...)( +Matches if the word in position var(index) is equal +to the corresponding var(string).

Anything up to and +including the var(index)th occurrence of this string will not be +considered part of the completion, but the rest will. var(index) may +be negative to count from the end: in most cases, var(index) will be +1 or -1. For example, + +nofill(tt(compctl -s '`users`' -x 'n[1,@]' -k hosts -- talk)) + +will usually complete usernames, but if you insert an tt(@) after the +name, names from the array var(hosts) (assumed to contain hostnames, +though you must make the array yourself) will be completed.

The left-hand side of +substitutions are not regular expressions, but character strings. Any +character can be used as the delimiter in place of `tt(/)'. A +backslash quotes the delimiter character. The character `tt(&)', in +the right-hand-side var(r), is replaced by the text from the +left-hand-side var(l). The `tt(&)' can be quoted with a backslash. A +null var(l) uses the previous string either from the previous var(l) +or from the contextual scan string var(s) from `tt(!?)var(s)'. You can +omit the rightmost delimiter if a newline immediately follows var(r); +the rightmost `tt(?)' in a context scan can similarly be omitted. +Note the same record of the last var(l) and var(r) is maintained +across all forms of expansion. + +By default, a history reference with no event specification refers to the same +line as the last history reference on that command line, unless it is the +first history reference in a command. In that case, a history reference +with no event specification always refers to the previous command. However, +if the option tt(CSH_JUNKIE_HISTORY) is set, +pindex(CSH_JUNKIE_HISTORY, use of) +then history reference with no +event specification will em(always) refer to the previous command. + +For example, `tt(!!:1)' +will always refer to the first word of the previous command, and `tt(!!$)' +will always refer to the last word of the previous command. And with +tt(CSH_JUNKIE_HISTORY) set, then `tt(!:1)' and `tt(!$)' +will function in the same manner as `tt(!!:1)' and `tt(!!$)', +respectively. However, if tt(CSH_JUNKIE_HISTORY) is unset, then +`tt(!:1)' and `tt(!$)' +will refer to the first and last words respectively, of the last command +referenced on the current command line. However, if they are the first history +reference on the command line, then they refer to the previous command. + +The character sequence `tt(^)var(foo)tt(^)var(bar)' +repeats the last command, replacing the string var(foo) with var(bar). + +If the shell encounters the character sequence `tt(!")' +in the input, the history mechanism is temporarily disabled until +the current list is fully parsed.

Also note that you can +set a parameter and use it as a directory name; +\fBzsh\fP will act as if \fCfoo\fP is a user +with the login directory \fC/usr/princeton/common/src\fP. +This is convenient, especially if you're sick of seeing +prompts like this: +.Ds +phoenix:/usr/princeton/common/src/X.V11R4/contrib/clients/xv/docs> +.De +If you get stuck in this position, you can give the current +directory a short name, like this: +.Ds +/usr/princeton/common/src/news/nntp/inews>\0inews=$PWD +/usr/princeton/common/src/news/nntp/inews>\0echo\0~inews +/usr/princeton/common/src/news/nntp/inews +~inews> +.De +When you reference a directory in the form \fC~inews\fP, +the shell assumes that you want the directory displayed +in this form; thus simply typing \fCecho ~inews\fP or +\fCcd ~inews\fP causes the prompt to be shortened. +You can define a shell function for this purpose: +.Ds +~inews>\0namedir\0()\0{\0$1=$PWD\0;\0\0:\0~$1\0} +~inews>\0cd\0/usr/princeton/bin +/usr/princeton/bin>\0namedir\0pbin +~pbin>\0cd\0/var/spool/mail +/var/spool/mail>\0namedir\0spool +~spool>\0cd\0.msgs +~spool/.msgs> +.De +You may want to add this one-line function to your \fC.zshrc\fP. + +\fBzsh\fP can also put the current directory in your title bar, +if you are using a windowing system. +One way to do this is with the \fCchpwd\fP function, which is +automatically executed by the shell whenever you change +directory. If you are using xterm, this will work: +.Ds +chpwd\0()\0{\0print\0-Pn\0'^[]2;%~^G'\0} +.De +The \fC-P\fP option tells \fCprint\fP to treat its arguments like a prompt +string; otherwise the \fC%~\fP would not be expanded. +The \fC-n\fP option suppresses the terminating newline, as with \fCecho\fP. +.PP +If you are using an IRIS \fCwsh\fP, do this: +.Ds +chpwd\0()\0{\0print\0-Pn\0'\e2201.y%~\e234'\0} +.De +The \fCprint -D\fP command has other uses. For example, to +print the current directory to standard output in short form, +you can do this: +.Ds +%\0print\0-D\0$PWD +~subbarao/src +.De +and to print each component of the path in short form: +.Ds +%\0print\0-D\0$path +/bin\0/usr/bin\0~locbin\0~locbin/X11\0~/bin +.De +.Sh "Directory Stacks" +.PP +If you use csh, you may know about directory stacks. +The \fCpushd\fP command puts the current directory on the +stack, and changes to a new directory; the \fCpopd\fP command +pops a directory off the stack and changes to it. +.Ds +phoenix%\0cd\0 +phoenix%\0PROMPT='Z\0%~>\0' +Z\0~>\0pushd\0/tmp +/tmp\0~ +Z\0/tmp>\0pushd\0/usr/etc +/usr/etc\0/tmp\0~ +Z\0/usr/etc>\0pushd\0/usr/bin +/usr/bin\0/usr/etc\0/tmp\0~ +Z\0/usr/bin>\0popd +/usr/etc\0/tmp\0~ +Z\0/usr/etc>\0popd +/tmp\0~ +Z\0/tmp>\0pushd\0/etc +/etc\0/tmp\0~ +Z\0/etc>\0popd\0 +/tmp\0~ +.De +\fBzsh\fP's directory stack commands work similarly.

+they have a lot of potential to cause confusion. +For example, if you defined a global alias called \fC|\fP (which is +possible), \fBzsh\fP would begin to act very strangely; every pipe +symbol would be replaced with the text of your alias. +To some extent, global aliases are like macros in C; +discretion is advised in using them and in choosing names for them. +Using names in all caps is not a bad idea, especially +for aliases which introduce shell metasyntax (like \fCM\fP and \fCGF\fP +above). +.PP +Note that \fBzsh\fP aliases are not like csh aliases. The syntax for +defining them is different, and they do not have arguments. +All your favorite csh aliases will probably not work under \fBzsh\fP. +For example, if you try: +.Ds +alias\0rm\0mv\0'\e!*\0/tmp/wastebasket' +.De +no aliases will be defined, but \fBzsh\fP will not report an error. +In csh, this line defines an alias that makes \fCrm\fP safe---files +that are \fCrm\fP'd will be moved to a temporary directory instead of +instantly destroyed. In \fBzsh\fP's syntax, however, this line asks +the shell to print any existing alias definitions for \fCrm\fP, +\fCmv\fP, or \fC!*\ /tmp/wastebasket\fP. Since there are none, most +likely, the shell will not print anything, although \fCalias\fP will +return a nonzero exit code. The proper syntax is this: +.Ds +alias\0rm='mv\0\e!*\0/tmp/wastebasket' +.De +However, this won't work either: +.Ds +%\0rm\0foo.dvi +zsh:\0no\0matches\0found:\0!* +.De +While this makes \fCrm\fP safe, it is certainly not what the user +intended. In \fBzsh\fP, you must use a shell function for this: +.Ds +%\0unalias\0rm +%\0rm\0()\0{\0mv\0$*\0/tmp/wastebasket\0} +%\0rm\0foo.dvi +%\0ls\0/tmp/wastebasket +foo.dvi +.De +While this is much cleaner and easier to read (I hope you will +agree), it is not csh-compatible. Therefore, a script to convert +csh aliases and variables has been provided. You should only need to use it +once, to convert all your csh aliases and parameters to \fBzsh\fP format: +.Ds +%\0csh +csh>\0alias +l\0\0\0\0\0\0\0ls\0-AF +more\0\0\0\0less +on\0\0\0\0\0\0last\0-2\0!:1\0;\0who\0|\0grep\0!:1 +csh>\0exit +%\0c2z\0>neat_zsh_aliases +%\0cat\0neat_zsh_aliases +alias\0l='ls\0-AF' +alias\0more='less' +on\0()\0{\0last\0-2\0$1\0;\0who\0|\0grep\0$1\0} +\&... +.De +The first two aliases were converted to regular \fBzsh\fP aliases, while +the third, since it needed to handle arguments, was converted to +a function. \fCc2z\fP can convert most aliases to \fBzsh\fP format without +any problems. However, if you're using some really arcane csh tricks, +or if you have an alias with a name like \fCdo\fP (which is reserved +in \fBzsh\fP), you may have to fix some of the aliases by hand. +.PP +The \fCc2z\fP script checks your csh setup, and produces a list +of \fBzsh\fP commands which replicate your aliases and parameter settings +as closely as possible. You could include its output in your +startup file, \fC.zshrc\fP. +.Sh "History" +.PP +There are several ways to manipulate history in \fBzsh\fP. +One way is to use csh-style \fC!\fP history: +.Ds +%\0/usr/local/bin/!:0\0!-2*:s/foo/bar/\0>>!$ +.De +If you don't want to use this, you can turn it off +by typing \fCsetopt nobanghist\fP. If you are afraid of accidentally +executing the wrong command you can set the \fIHISTVERIFY\fP option. +If this option is set, commands that result from history expansion +will not be executed immediately, but will be put back into the editor +buffer for further consideration. +.PP +If you're not familiar with \fC!\fP history, here follows some +explanation. History substitutions always start with a \fC!\fP, +commonly called \*Qbang\*U. After the \fC!\fP comes an (optional) +designation of which \*Qevent\*U (command) to use, then a colon, and +then a designation of what word of that command to use. For example, +\fC!-\fIn\fR refers to the command \fIn\fP commands ago. +.Ds +%\0ls +foo\0\0bar +%\0cd\0foo +%\0!-2 +ls +baz\0\0bam +.De +No word designator was used, which means that the whole command +referred to was repeated. Note that the shell will echo the result of +the history substitution. The word designator can, among other +things, be a number indicating the argument to use, where \fC0\fP is +the command. +.Ds +%\0/usr/bin/ls\0foo +foo +%\0!:0\0bar +/usr/bin/ls\0bar +bar +.De +In this example, no event designator was used, which tells \fBzsh\fP +to use the previous command. A \fC$\fP specifies the last argument +.Ds +%\0mkdir\0/usr/local/lib/emacs/site-lisp/calc +%\0cd\0!:$ +cd\0/usr/local/lib/emacs/site-lisp/calc +.De +If you use more words of the same command, only the first \fC!\fP +needs an event designator. +.Ds +%\0make\0prig\0>>\0make.log +make:\0***\0No\0rule\0to\0make\0target\0`prig'.\0\0Stop. +%\0cd\0src +%\0!-2:0\0prog\0>>\0!:$ +make\0prog\0>>\0make.log +.De +This is different from csh, where a bang with no event designator +always refers to the previous command. If you actually like this +behaviour, set the \fICSHJUNKIEHISTORY\fP option. +.Ds +%\0setopt\0cshjunkiehistory +%\0!-2:0\0prog2\0>>\0!:$ +make\0prog2\0>>\0cshjunkiehistory +.De +Another way to use history is to use the \fCfc\fP command.

You can +tell \fBzsh\fP to complete commands as the first argument to such a +command and then use the completion method of the second command. The +\fC-l\fP flag with a null-string argument is used for this. +.Ds +%\0compctl\0-l\0''\0nohup\0exec +%\0nohup\0comp\fITAB\fC +%\0nohup\0compress\0_ +%\0nohup\0compress\0fil\fITAB\fC +%\0nohup\0compress\0filename\0_ +.De +Sometimes you would like to run really complicated commands to find +out what the possible completions are. To do this, you can specify a +shell function to be called that will assign the possible completions +to a variable called reply. Note that this variable must be an array. +Here's another (much slower) way to get the completions for \fCco\fP +and friends: +.Ds +%\0function\0getrcs\0{ +>\0reply=() +>\0for\0i\0in\0RCS/* +>\0\0\0do +>\0\0\0reply=($reply[*]\0$(basename\0$i\0,v)) +>\0\0\0done +>\0} +%\0compctl\0-K\0getrcs\0co\0rlog\0rcs +.De +Some command arguments use a prefix that is not a part of the things +to complete.

It is somewhat annoying to specify that the arguments +of TeX should end in \fC.tex\fP and then not be able to complete these +other files. Therefore you can specify things like \*QComplete to +files ending in \fC.tex\fP if available, otherwise complete to any +filename.\*U. This is done with \fIxor\fPed completion: +.Ds +%\0compctl\0-g\0'*.tex'\0+\0-f\0tex +.De +The \fC+\fP tells the editor to only take the next thing into account +if the current one doesn't generate any matches. If you have not +changed the default completion, the above example is in fact +equivalent to +.Ds +%\0compctl\0-g\0'*.tex'\0+\0tex +.De +as a lone \fC+\fP at the end is equivalent to specifying the default +completion after the \fC+\fP. This form of completion is also +frequently used if you want to run some command only on a certain type +of files, but not necessarily in the current directory. In this case +you will want to complete both files of this type and directories. +Depending on your preferences you can use either of +.Ds +%\0compctl\0-g\0'*.ps'\0+\0-g\0'*(-/)'\0ghostview +%\0compctl\0-g\0'*.ps\0*(-/)'\0ghostview +.De +where the first one will only complete directories (and symbolic links +pointing to directories) if no postscript file matches the already +typed part of the argument. +.Sh "Extended completion" +.PP +If you play with completion, you will soon notice that you would like +to specify what to complete, depending on what flags you give to the +command and where you are on the command line. For example, a command +could take any filename argument after a \fC-f\fP flag, a username +after a \fC-u\fP flag and an executable after a \fC-x\fP flag. This +section will introduce you to the ways to specify these things. To +many people it seems rather difficult at first, but taking the trouble +to understand it can save you lots of typing in the end. Even I keep +being surprised when \fBzsh\fP manages to complete a small or even +empty prefix to the right file in a large directory. +.PP +To tell \fBzsh\fP about these kinds of completion, you use \*Qextended +completion\*U by specifying the \fC-x\fP flag to compctl. The +\fC-x\fP flag takes a list of patterns/flags pairs. The patterns +specify when to complete and the flags specify what. The flags are +simply those mentioned above, like \fC-f\fP or \fC-g \fIglob +pattern\fR. +.PP +As an example, the \fCr[\fIstring1\fC,\fIstring2\fC]\fR pattern +matches if the cursor is after something that starts with +\fIstring1\fP and before something that starts with \fIstring2\fP. +The \fIstring2\fP is often something that you do not want to match +anything at all. +.Ds +%\0ls +foo1\0\0\0bar1\0\0\0foo.Z\0\0bar.Z +%\0compctl\0-g\0'^*.Z'\0-x\0'r[-d,---]'\0-g\0'*.Z'\0--\0compress +%\0compress\0f\fITAB\fP +%\0compress\0foo1\0_ +%\0compress\0-d\0f\fITAB\fP +%\0compress\0-d\0foo.Z\0_ +.De +In the above example, if the cursor is after the \fC-d\fP the pattern +will match and therefore \fBzsh\fP uses the \fC-g *.Z\fP flag that will only +complete files ending in \fC.Z\fP. Otherwise, if no pattern matches, +it will use the flags before the \fC-x\fP and in this case complete +every file that does not end in \fC.Z\fP. +.PP +The \fCs[\fIstring\fC]\fR pattern matches if the current word starts +with \fIstring\fP. The \fIstring\fP itself is not considered to be +part of the completion. +.Ds +%\0compctl\0-x\0's[-]'\0-k\0signals\0--\0kill +%\0kill\0-H\fITAB\fP +%\0kill\0-HUP\0_ +.De +The \fCtar\fP command takes a tar file as an argument after the +\fC-f\fP option. The \fCc[\fIoffset\fC,\fIstring\fC]\fR pattern +matches if the word in position \fIoffset\fP relative to the current +word is \fIstring\fP. More in particular, if \fIoffset\fP is -1, it +matches if the previous word is \fIstring\fP. This suggests +.Ds +%\0compctl\0-f\0-x\0'c[-1,-f]'\0-g\0'*.tar'\0--\0tar +.De +But this is not enough. The \fC-f\fP option could be the last of a +longer string of options. \fCC[\fR...\fC,\fR...\fC]\fR is just like +\fCc[\fR...\fC,\fR...\fC]\fR, except that it uses glob-like pattern +matching for \fIstring\fP. So +.Ds +%\0compctl\0-f\0-x\0'C[-1,-*f]'\0-g\0'*.tar'\0--\0tar +.De +will complete tar files after any option string ending in an \fCf\fP. +But we'd like even more. Old versions of tar used all options as the +first argument, but without the minus sign. This might be +inconsistent with option usage in all other commands, but it is still +supported by newer versions of \fCtar\fP. So we would also like to +complete tar files if the first argument ends in an \fCf\fP and we're +right behind it. +.PP +We can `and' patterns by putting them next to each other with a space +between them. We can `or' these sets by putting comma's between them. +We will also need some new patterns. \fCp[\fInum\fC]\fR will match if +the current argument (the one to be completed) is the \fInum\fPth +argument. \fCW[\fIindex\fC,\fIpattern\fC]\fR will match if the +argument in place \fIindex\fP matches the \fIpattern\fP. This gives +us +.Ds +%\0compctl\0-f\0-x\0'C[-1,-*f]\0,\0W[1,*f]\0p[2]'\0-g\0'*.tar'\0--\0tar +.De +In words: If the previous argument is an option string that ends in an +\fCf\fP, or the first argument ended in an \fCf\fP and it is now the +second argument, then complete only filenames ending in \fC.tar\fP. +.PP +All the above examples used only one set of patterns with one +completion flag. You can use several of these pattern/flag pairs +separated by a \fC-\fP. The first matching pattern will be used. +Suppose you have a version of \fCtar\fP that supports compressed files +by using a \fC-Z\fP option. Leaving the old tar syntax aside for a +moment, we would like to complete files ending in \fC.tar.Z\fP if a +\fC-Z\fP option has been used and files ending in \fC.tar\fP +otherwise, all this only after a \fC-f\fP flag. Again, the \fC-Z\fP +can be alone or it can be part of a longer option string, perhaps the +same as that of the \fC-f\fP flag. Here's how to do it; note the +backslash and the secondary prompt which are not part of the +\fCcompctl\fP command. +.Ds +%\0compctl\0-f\0-x\0'C[-1,-*Z*f]\0,\0R[-*Z*,---]\0C[-1,-*f]'\0-g\0'*.tar.Z'\0-\0\e +>\0'C[-1,-*f]'\0-g\0'*.tar'\0--\0tar +.De +The first pattern set tells us to match if either the previous +argument was an option string including a \fCZ\fP and ending in an +\fCf\fP or there was an option string with a \fCZ\fP somewhere and the +previous word was any option string ending in an \fCf\fP. If this is +the case, we need a compressed tar file. Only if this is not the case +the second pattern set will be considered. By the way, +\fCR[\fIpattern1\fC,\fIpattern2\fC]\fR is just like +\fCr[\fR...\fC,\fR...\fC]\fR except that it uses pattern matching with +shell metacharacters instead of just strings. +.PP +You will have noticed the \fC--\fP before the command name. This ends +the list of pattern/flag pairs of \fC-x\fP. It is usually used just +before the command name, but you can also use an extended completion +as one part of a list of xored completions, in which case the \fC--\fP +appears just before one of the \fC+\fP signs. +.PP +Note the difference between using extended completion as part of a +list of xored completions as in +.Ds +%\0ls +foo\0\0bar +%\0compctl\0-x\0'r[-d,---]'\0-g\0'*.Z'\0--\0+\0-g\0'^*.Z'\0compress +%\0compress\0-d\0f\fITAB\fP +%\0compress\0-d\0foo\0_ +.De +and specifying something before the \fC-x\fP as in +.Ds +%\0compctl\0-g\0'^*.Z'\0-x\0'r[-d,---]'\0-g\0'*.Z'\0--\0compress +%\0compress\0-d\0f\fITAB\fP +%\0compress\0-d\0f_ +.De +In the first case, the alternative glob pattern (\fC^*.Z\fP) will be +used if the first part does not generate any possible completions, +while in the second case the alternative glob pattern will only be +used if the \fCr[\fR...\fC]\fR pattern doesn't match. +.Sh "Bindings" +.PP +Each of the editor commands we have seen was actually a function bound +by default to a certain key. The real names of the commands are: +.Ds +\fCexpand-or-complete\0\0\0\fITAB\fR +\fCpush-line\0\0\0\0\0\0\0\0\0\0\0\0\fIESC-Q\fR +\fCrun-help\0\0\0\0\0\0\0\0\0\0\0\0\0\fIESC-H\fR +\fCaccept-and-hold\0\0\0\0\0\0\fIESC-A\fR +\fCquote-line\0\0\0\0\0\0\0\0\0\0\0\fIESC-'\fR +.De +These bindings are arbitrary; you could change them if you want. +For example, to bind \fCaccept-line\fP to \fI^Z\fP: +.Ds +%\0bindkey\0'^Z'\0accept-line +.De +Another idea would be to bind the delete key to \fCdelete-char\fP; +this might be convenient if you use \fI^H\fP for backspace. +.Ds +%\0bindkey\0'^?'\0delete-char +.De +Or, you could bind \fI^X\fP\fI^H\fP to \fCrun-help\fP: +.Ds +%\0bindkey\0'^X^H'\0run-help +.De +Other examples: +.Ds +%\0bindkey\0'^X^Z'\0universal-argument +%\0bindkey\0'\0'\0magic-space +%\0bindkey\0-s\0'^T'\0'uptime +>\0' +%\0bindkey\0'^Q'\0push-line-or-edit +.De +\fCuniversal-argument\fP multiplies the next command by 4. +Thus \fI^X\fP\fI^Z\fP\fI^W\fP might delete the last four words on the line. +If you bind space to \fCmagic-space\fP, then csh-style history +expansion is done on the line whenever you press the space bar. +.PP +Something that often happens is that I am typing a multiline command +and discover an error in one of the previous lines. In this case, +\fCpush-line-or-edit\fP will put the entire multiline construct into +the editor buffer. If there is only a single line, it is equivalent +to \fCpush-line\fP. +.PP +The \fC-s\fP flag to \fCbindkey\fP specifies that you are binding the key +to a string, not a command. Thus \fCbindkey -s '^T' 'uptime\en'\fP +lets you VMS lovers get the load average whenever you press \fI^T\fP. +.PP +If you have a NeXT keyboard, the one with the \fC|\fP and \fC\e\fP keys +very inconveniently placed, the following +bindings may come in handy: +.Ds +%\0bindkey\0-s\0'\ee/'\0'\e\e' +%\0bindkey\0-s\0'\ee='\0'|' +.De +Now you can type \fIALT-/\fP to get a backslash, and \fIALT-=\fP to +get a vertical bar. This only works inside \fBzsh\fP, of course; +\fCbindkey\fP has no effect on the key mappings inside \fCtalk\fP +or \fCmail\fP, etc. +.PP +Some people like to bind \fC^S\fP and \fC^Q\fP to editor commands. +Just binding these has no effect, as the terminal will catch them and +use them for flow control. You could unset them as stop and start +characters, but most people like to use these for external commands. +The solution is to set the \fINOFLOWCONTROL\fP option. This will +allow you to bind the start and stop characters to editor commands, +while retaining their normal use for external commands. +.Sh "Parameter Substitution" +.PP +In \fBzsh\fP, parameters are set like this: +.Ds +%\0foo=bar +%\0echo\0$foo +bar +.De +Spaces before or after the \fC=\fP are frowned upon: +.Ds +%\0foo\0=\0bar +zsh:\0command\0not\0found:\0foo +.De +Also, \fCset\fP doesn't work for setting parameters: +.Ds +%\0set\0foo=bar +%\0set\0foo\0=\0bar +%\0echo\0$foo + +% +.De +Note that no error message was printed. This is because both +of these commands were perfectly valid; the \fCset\fP builtin +assigns its arguments to the \fIpositional parameters\fP +(\fC$1\fP, \fC$2\fP, etc.). +.Ds +%\0set\0foo=bar +%\0echo\0$1 +foo=bar +%\0set\0foo\0=\0bar +%\0echo\0$3\0$2 +bar\0= +.De +If you're really intent on using the csh syntax, define a +function like this: +.Ds +%\0set\0()\0{ +>\0\0\0\0eval\0"$1$2$3" +>\0} +%\0set\0foo\0=\0bar +%\0set\0fuu=brrr +%\0echo\0$foo\0$fuu +bar\0brrr +.De +But then, of course you can't use the form of \fCset\fP with +options, like \fCset -F\fP (which turns off filename generation). +Also, the \fCset\fP command by itself won't list all the parameters +like it should. +To get around that you need a \fCcase\fP statement: +.Ds +%\0set\0()\0{ +>\0\0\0\0case\0$1\0in +>\0\0\0\0-*|+*|'')\0builtin\0set\0$*\0;; +>\0\0\0\0*)\0eval\0"$1$2$3"\0;; +>\0\0\0\0esac +>\0} +.De +For the most part, this should make csh users happy. +.PP +The following sh-style operators are supported in \fBzsh\fP: +.Ds +%\0unset\0null +%\0echo\0${foo-xxx} +bar +%\0echo\0${null-xxx} +xxx +%\0unset\0null +%\0echo\0${null=xxx} +xxx +%\0echo\0$null +xxx +%\0echo\0${foo=xxx} +bar +%\0echo\0$foo +bar +%\0unset\0null +%\0echo\0${null+set} + +%\0echo\0${foo+set} +set +.De +Also, csh-style \fC:\fP modifiers may be appended to a parameter +substitution. +.Ds +%\0echo\0$PWD +/home/learning/pf/zsh/zsh2.00/src +%\0echo\0$PWD:h +/home/learning/pf/zsh/zsh2.00 +%\0echo\0$PWD:h:h +/home/learning/pf/zsh +%\0echo\0$PWD:t +src +%\0name=foo.c +%\0echo\0$name +foo.c +%\0echo\0$name:r +foo +%\0echo\0$name:e +c +.De +The equivalent constructs in ksh (which are also supported in \fBzsh\fP) +are a bit more general and easier to remember. +When the shell expands \fC${foo#\fR\fIpat\fR\fC}\fR, +it checks to see if \fIpat\fP matches a substring at the beginning +of the value +of \fCfoo\fP. If so, it removes that portion of \fCfoo\fP, using the shortest +possible match. +With \fC${foo##\fR\fIpat\fR\fC}\fR, the longest possible match is removed. +\fC${foo%\fR\fIpat\fR\fC}\fR and \fC${foo%%\fR\fIpat\fR\fC}\fR remove the match +from the end. +Here are the ksh equivalents of the \fC:\fP modifiers: +.Ds +%\0echo\0${PWD%/*} +/home/learning/pf/zsh/zsh2.00 +%\0echo\0${PWD%/*/*} +/home/learning/pf/zsh +%\0echo\0${PWD##*/} +src +%\0echo\0${name%.*} +foo +%\0echo\0${name#*.} +c +.De +\fBzsh\fP also has upper/lowercase modifiers: +.Ds +%\0xx=Test +%\0echo\0$xx:u +TEST +%\0echo\0$xx:l +test +.De +and a substitution modifier: +.Ds +%\0echo\0$name:s/foo/bar/ +bar.c +%\0ls +foo.c\0\0\0\0foo.h\0\0\0\0foo.o\0\0\0\0foo.pro +%\0for\0i\0in\0foo.*;\0mv\0$i\0$i:s/foo/bar/ +%\0ls +bar.c\0\0\0\0bar.h\0\0\0\0bar.o\0\0\0\0bar.pro +.De +There is yet another syntax to modify substituted parameters.

+------------------------------------------------------------------------ +If you suspend "man", zle seems to get into cooked mode. It works ok +for plain "less". +It is not specific neither to man nor to zsh. +E.g. call the following program foo: +#include <sys/wait.h> +#include <unistd.h> + +int main(int argc, char *argv[]) +{ + int status; + + if (!fork()) /* child */ + execvp(argv[1], argv + 1); + else /* parent */ + wait(&status); +} +Then if you suspend +% foo less something +from zsh/bash, zle/readline gets into cooked mode. +------------------------------------------------------------------------ +% zsh -c 'cat a_long_file | less ; :' +can be interrupted with ^C. The prompt comes back and less is orphaned. +If you go to the end of the file with less and cat terminates, ^C +will not terminate less. The `; :' after less forces zsh to fork before +executing less. +------------------------------------------------------------------------ +The pattern %?* matches names beginning with %? instead of names with at +least two characters beginning with %. This is a hack to allow %?foo job +substitution without quoting. This behaviour is incompatible with sh +and ksh and may be removed in the future. A good fix would be to keep +such patterns unchanged if they do not match regardless of the state of +the nonomatch and nullglob options. +------------------------------------------------------------------------ diff --git a/Etc/CONTRIBUTORS b/Etc/CONTRIBUTORS new file mode 100644 index 000000000..52d664fad --- /dev/null +++ b/Etc/CONTRIBUTORS @@ -0,0 +1,127 @@ +---------------- +ZSH CONTRIBUTORS +---------------- + +Zsh was originally written by Paul Falstad <pf@zsh.org>.

It includes + enhancements of many types, notably in the command-line editor, + options for customising its behaviour, filename globbing, features + to make C-shell (csh) users feel more at home and extra features + drawn from tcsh (another `custom' shell). + + It was written by Paul Falstad when a student at Princeton; however, + Paul doesn't maintain it any more and enquiries should be sent to + the mailing list (see question link(5.2)(52)). Zsh is distributed under a + standard Berkeley style copyright. + + For more information, the files Doc/intro.txt or Doc/intro.troff + included with the source distribution are highly recommended. A list + of features is given in FEATURES, also with the source. + + +sect(What is it good at?) + + Here are some things that zsh is particularly good at. No claim of + exclusivity is made, especially as shells copy one another, though + in the areas of command line editing and globbing zsh is well ahead + of the competition. I am not aware of a major interactive feature + in any other freely-available shell which zsh does not also have + (except smallness). + + itemize( + it() Command line editing: + itemize( + it() programmable completion: incorporates the ability to use + the full power of zsh globbing (compctl -g), + it() multi-line commands editable as a single buffer (even files!), + it() variable editing (vared), + it() command buffer stack, + it() print text straight into the buffer for immediate editing (print -z), + it() execution of unbound commands, + it() menu completion, + it() variable, editing function and option name completion, + it() inline expansion of variables, history commands. + ) + it() Globbing --- extremely powerful, including: + itemize( + it() recursive globbing (cf. find), + it() file attribute qualifiers (size, type, etc. also cf. find), + it() full alternation and negation of patterns. + ) + it() Handling of multiple redirections (simpler than tee). + it() Large number of options for tailoring. + it() Path expansion (=foo -> /usr/bin/foo). + it() Adaptable messages for spelling, watch, time as well as prompt + (including conditional expressions). + it() Named directories. + it() Comprehensive integer arithmetic. + it() Manipulation of arrays (including reverse subscripting). + it() Spelling correction. + ) + + +sect(On what machines will it run?) + + From version 3.0, zsh uses GNU autoconf as the installation + mechanism. This considerably increases flexibility over the old + `buildzsh' mechanism. Consequently, zsh should compile and run on + any modern version of UNIX, and a great many not-so-modern versions + too. The file Etc/MACHINES in the distribution has more details. + + There are also now separate ports for Windows and OS/2, see `Where + do I get it' below. + + If you need to change something to support a new machine, it would be + appreciated if you could add any necessary preprocessor code and + alter configure.in and config.h.in to configure zsh automatically, + then send the required context diffs to the list (see question + link(5.2)(52)). Changes based on version 2.5 are very unlikely to + be useful. + + To get it to work, retrieve the source distribution (see question + link(1.6)(16)), un-gzip it, un-tar it and read the INSTALL file in the top + directory. Also read the Etc/MACHINES file for up-to-date + information on compilation on certain architectures. + + mybf(Note for users of nawk) (The following information comes from Zoltan + Hidvegi): On some systems nawk is broken and produces an incorrect + signames.h file. This makes the signals code unusable. This often happens + on Ultrix, HP-UX, IRIX (?). Install gawk if you experience such problems. + + +sect(What's the latest version?) + + Zsh 3.0.5 is the latest production version. The new major number 3.0 + largely reflects the considerable internal changes in zsh to make it + more reliable, consistent and (where possible) compatible. Those + planning on upgrading their zsh installation should take a look at + the list of incompatibilities at the end of link(5.1)(51). This is + longer than usual due to enhanced sh, ksh and POSIX compatibility. + + The beta version 3.1.4 is also available. Development of zsh is + usually patch by patch, with each intermediate version publicly + available. Note that this `open' development system does mean bugs + are sometimes introduced into the most recent archived version. + These are usually fixed quickly. + + Note also that as the shell changes, it may become incompatible with + older versions; see the end of question link(5.1)(51) for a partial list. + Changes of this kind are almost always forced by an awkward or + unnecessary feature in the original design (as perceived by current + users), or to enhance compatibility with other Bourne shell + derivatives, or (most recently) to provide POSIX compliancy. + + +sect(Where do I get it?) +label(16) + + The archive is now run by email(Andrew Main <zefram@tao.co.uk>). + The following are known mirrors (kept frequently up to date); the + first is the official archive site, currently in Australia.

This can be avoided if you use + mytt(function) to define a function, which doesn't expand aliases. It is + possible to argue for extra warnings somewhere in this mess. Luckily, + it is not possible to define mytt(function) as an alias. + + Bart Schaefer's rule is: Define first those aliases you expect to + use in the body of a function, but define the function first if the + alias has the same name as the function. + + +sect(Similarities with tcsh) + + (The sections on csh apply too, of course.) Certain features have + been borrowed from tcsh, including tt($watch), tt(run-help), tt($savehist), + tt($histlit), periodic commands etc., extended prompts, tt(sched) + and tt(which) built-ins. Programmable completion was inspired by, + but is entirely different to, tcsh's mytt(complete). (There is a perl + script called tt(lete2ctl) in the Misc directory of the source + distribution to convert mytt(complete) to mytt(compctl) statements.) + This list is not definitive: some features have gone in the other + direction. + + If you're missing the editor function tt(run-fg-editor), try something + with mytt(bindkey -s) (which binds a string to a keystroke), e.g. + verb( + bindkey -s '^z' '\eqfg %$EDITOR:t\n' + ) + which pushes the current line onto the stack and tries to bring a job + with the basename of your editor into the foreground. mytt(bindkey -s) + allows limitless possibilities along these lines. You can execute + any command in the middle of editing a line in the same way, + corresponding to tcsh's mytt(-c) option: + verb( + bindkey -s '^p' '\eqpwd\n' + ) + In both these examples, the mytt(\eq) saves the current input line to + be restored after the command runs; a better effect with multiline + buffers is achieved if you also have + verb( + bindkey '\eq' push-input + ) + to save the entire buffer. + + +sect(Similarities with bash) + + The Bourne-Again Shell, bash, is another enhanced Bourne-like shell; + the most obvious difference from zsh is that it does not attempt to + emulate the Korn shell. Since both shells are under active + development it is probably not sensible to be too specific here. + Broadly, bash has paid more attention to standards compliancy + (i.e. POSIX) for longer, and has so far avoided the more abstruse + interactive features (programmable completion, etc.) that zsh has. + + +sect(Shouldn't zsh be more/less like ksh/(t)csh?) + + People often ask why zsh has all these `unnecessary' csh-like features, + or alternatively why zsh doesn't understand more csh syntax. This is + far from a definitive answer and the debate will no doubt continue. + + Paul's object in writing zsh was to produce a ksh-like shell which + would have features familiar to csh users. For a long time, csh was + the preferred interactive shell and there is a strong resistance to + changing to something unfamiliar, hence the additional syntax and + CSH_JUNKIE options. This argument still holds. On the other hand, + the arguments for having what is close to a plug-in replacement for ksh + are, if anything, even more powerful: the deficiencies of csh as a + programming language are well known (look in any Usenet FAQ archive, e.g. + url(http://www.cis.ohio-state.edu/hypertext/faq/usenet/unix-faq/\ + shell/csh-whynot/faq.html) +(http://www.cis.ohio-state.edu/hypertext/faq/usenet/unix-faq/shell/csh-whynot/faq.html) + if you are in any doubt) and zsh is able to run many standard + scripts such as /etc/rc. + + Of course, this makes zsh rather large and feature-ridden so that it + seems to appeal mainly to hackers. The only answer, perhaps not + entirely satisfactory, is that you have to ignore the bits you don't + want. The introduction of loadable in modules in version 3.1 should + help. + + +chapter(How to get various things to work) + +sect(Why does mytt($var) where mytt(var="foo bar") not do what I expect?) +label(31) + + In most Bourne-shell derivatives, multiple-word variables such as + verb( + var="foo bar" + ) + are split into words when passed to a command or used in a mytt(for foo in + $var) loop. By default, zsh does not have that behaviour: the + variable remains intact. (This is not a bug! See below.) An option + (SHWORDSPLIT) exists to provide compatibility. + + For example, defining the function args to show the number of its + arguments: + verb( + args() { echo $#; } + ) + and with our definition of `var', + verb( + args $var + ) + produces the output `1'. After + verb( + setopt shwordsplit + ) + the same function produces the output `2', as with sh and ksh. + + Unless you need strict sh/ksh compatibility, you should ask yourself + whether you really want this behaviour, as it can produce unexpected + effects for variables with entirely innocuous embedded spaces. This + can cause horrendous quoting problems when invoking scripts from + other shells. The natural way to produce word-splitting behaviour + in zsh is via arrays. For example, + verb( + set -A array one two three twenty + ) + (or + verb( + array=(one two three twenty) + ) + if you prefer), followed by + verb( + args $array + ) + produces the output `4', regardless of the setting of SHWORDSPLIT. + Arrays are also much more versatile than single strings. Probably + if this mechanism had always been available there would never have + been automatic word splitting in scalars, which is a sort of + uncontrollable poor man's array. + + Note that this happens regardless of the value of the internal field + separator, tt($IFS); in other words, with mytt(IFS=:; foo=a:b; args $foo) + you get the answer 1. + + Other ways of causing word splitting include a judicious use of + `eval': + verb( + sentence="Longtemps, je me suis couch\\'e de bonne heure." + eval "words=($sentence)" + ) + after which $words is an array with the words of $sentence (note + characters special to the shell, such as the mytt(') in this example, + must already be quoted), or, less standard but more reliable, + turning on SHWORDSPLIT for one variable only: + verb( + args ${=sentence} + ) + always returns 8 with the above definition of mytt(args). (In older + versions of zsh, tt(${=foo}) toggled SHWORDSPLIT; now it forces it on.) + + Note also the tt("$@") method of word splitting is always available in zsh + functions and scripts (though strictly this does array splitting, not + word splitting). + + SHWORDSPLIT is set when zsh is invoked with the names `ksh' or `sh', + or (entirely equivalent) when mytt(emulate ksh) or mytt(emulate sh) is in + effect. + + +sect(What is the difference between `export' and the ALL_EXPORT option?) + + Normally, you would put a variable into the environment by using + mytt(export var).

Since all shell variables are visible to + commands, there is no protection against this. + ) + For these reasons it is usually best to avoid ALL_EXPORT unless you + have a specific use for it. One safe use is to set it before + creating a list of variables in an initialisation file, then unset + it immediately afterwards. Only those variables will be automatically + exported. + + +sect(How do I turn off spelling correction/globbing for a single command?) + + In the first case, you presumably have mytt(setopt correctall) in an + initialisation file, so that zsh checks the spelling of each word in + the command line. You probably do not want this behaviour for + commands which do not operate on existing files. + + The answer is to alias the offending command to itself with + mytt(nocorrect) stuck on the front, e.g. + verb( + alias mkdir='nocorrect mkdir' + ) + + To turn off globbing, the rationale is identical: + verb( + alias mkdir='noglob mkdir' + ) + You can have both tt(nocorrect) and tt(noglob), if you like, but the + tt(nocorrect) must come first, since it is needed by the line editor, + while tt(noglob) is only handled when the command is examined. + + Note also that a shell function won't work: the no... directives must + be expanded before the rest of the command line is parsed. + + +sect(How do I get the meta key to work on my xterm?) +label(34) + + As stated in the manual, zsh needs to be told about the meta key by + using mytt(bindkey -me) or mytt(bindkey -mv) in your .zshrc or on the + command line. You probably also need to tell the terminal driver to + allow the `meta' bit of the character through; mytt(stty pass8) is the + usual incantation. Sample .zshrc entry: + verb( + [[ $TERM = "xterm" ]] && stty pass8 && bindkey -me + ) + or, on SYSVR4-ish systems without pass8, + verb( + [[ $TERM = "xterm" ]] && stty -parenb -istrip cs8 && bindkey -me + ) + (disable parity detection, don't strip high bit, use 8-bit characters). + Make sure this comes myem(before) any bindkey entries in your .zshrc which + redefine keys normally defined in the emacs/vi keymap. + + You don't need the mytt(bindkey) to be able to define your own sequences + with the meta key, though you still need the mytt(stty). + + +sect(How do I automatically display the directory in my xterm title bar?) + + You should use the special function mytt(chpwd), which is called when + the directory changes. The following checks that standard output is + a terminal, then puts the directory in the title bar if the terminal + is an tt(xterm) or a tt(sun-cmd). + + verb( + chpwd() { + [[ -t 1 ]] || return + case $TERM in + sun-cmd+CHAR(41) print -Pn "\e]l%~\e\\" + ;; + xterm+CHAR(41) print -Pn "\e]2;%~\a" + ;; + esac + } + ) + + Change mytt(%~) if you want the message to be different. (The mytt(-P) + option interprets such sequences just like in prompts, in this case + producing the current directory; you can of course use mytt($PWD) here, + but that won't use the mytt(~) notation which I find clearer.) Note that + when the tt(xterm) starts up you will probably want to call tt(chpwd) + directly: just put mytt(chpwd) in tt(.zshrc) after it is defined or \ + autoloaded. + + +sect(How do I make the completion list use eight bit characters?) + + A traditional UNIX environment (character terminal and ASCII + character sets) is not sufficient to be able to handle non-ASCII + characters, and there are so many possible enhancements that in + general this is hard. However, if you have something like an xterm + using a standard character set like ISO-8859-1 (which is often the + default for xterm), read on. You should also note question + link(3.4)(34) on the subject of eight bit characters. + + You are probably creating files with names including non-ASCII + accented characters, and find they show up in the completion list as + verb(\M-i) or something such. This is because the library routines + (not zsh itself) which test whether a character is printable have + replied that it is not; zsh has simply found a way to show them + anyway. + + The answer, under a modern POSIXy operating system, is to find a + locale where these are treated as printable characters. Zsh has + handling for locales built in and will recognise when you set a + relevant variable. You need to look in /usr/lib/locale to find one + which suits you; the subdirectories correspond to the locale names. + The simplest possibility is likely to be en_US, so that the simplest + answer to your problem is to set + + verb( + LC_CTYPE=en_US + ) + + when your terminal is capable of showing eight bit characters. If + you only have a default domain (called C), you may need to have some + additional files installed on your system. + + +sect(Why do the cursor (arrow) keys not work?) + + The cursor keys send different codes depending on the terminal; zsh + only binds the most well known versions. If you see these problems, + try putting the following in your tt(.zshrc): + + verb( + bindkey "$(echotc kl)" backward-char + bindkey "$(echotc kr)" forward-char + bindkey "$(echotc ku)" up-line-or-history + bindkey "$(echotc kd)" down-line-or-history + ) + + If you use vi mode, use mytt(vi-backward-char) and mytt(vi-forward-char) + where appropriate. + + Note, however, that up to version 3.0 binding arbitrary multiple key + sequences can cause problems, so check that this works with your set + up first. Also, from version 3.1.3, more sequences are supported by + default, namely those in the form mytt(<ESC>O) followed by tt(A), + tt(B), tt(C) or tt(D), as well as the corresponding set beginning + mytt(<ESC>[), so this may be redundant. + + +sect(Why does my terminal act funny in some way?) + + If you are using an OpenWindows cmdtool as your terminal, any + escape sequences (such as those produced by cursor keys) will be + swallowed up and never reach zsh. Either use shelltool or avoid + commands with escape sequences. You can also disable scrolling from + the cmdtool pane menu (which effectively turns it into a shelltool). + If you still want scrolling, try using an xterm with the scrollbar + activated. + + If that's not the problem, and you are using stty to change some tty + settings, make sure you haven't asked zsh to freeze the tty settings: + type + verb( + ttyctl -u + ) + before any stty commands you use. + + On the other hand, if you aren't using stty and have problems you may + need the opposite: mytt(ttyctl -f) freezes the terminal to protect it + from hiccups introduced by other programmes (kermit has been known to + do this). + + If myem(that)'s not the problem, and you are having difficulties with + external commands (not part of zsh), and you think some terminal + setting is wrong (e.g. tt(^V) is getting interpreted as `literal next + character' when you don't want it to be), try + verb( + ttyctl -u + STTY='lnext "^-"' commandname + ) + (in this example), or just export STTY for all commands to see. Note + that zsh doesn't reset the terminal completely afterwards: just the + modes it uses itself and a number of special processing characters + (see the tt(stty(1)) manual page). + + At some point there may be an overhaul which allows the terminal + modes used by the shell to be modified separately from those seen by + external programmes. This is partially implemented already: from 2.5, + the shell is less susceptible to mode changes inherited from + programmes than it used to be. + + +sect(Why does zsh not work in an Emacs shell mode any more?) + + (This information comes from Bart Schaefer and other zsh-workers.) + + Emacs 19.29 or thereabouts stopped using a terminal type of "emacs" + in shell buffers, and instead sets it to "dumb". Zsh only kicks in + its special I'm-inside-emacs initialization when the terminal type + is "emacs". + + Probably the most reliable way of dealing with this is to look for + the environment variable mytt($EMACS), which is set to mytt(t) in + Emacs' shell mode. Putting + verb( + [[ $EMACS = t ]] && unsetopt zle + ) + in your .zshrc should be sufficient. + + Another method is to put + verb( + #!/bin/sh + TERM=emacs exec zsh + ) + into a file ~/bin/eshell, then mytt(chmod +x ~/bin/eshell), and + tell emacs to use that as the shell by adding + verb( + (setenv "ESHELL" "~/bin/eshell") + ) + to ~/.emacs. + + +sect(Why do my autoloaded functions not autoload [the first time]?) + + The problem is that there are two possible ways of autoloading a + function (see the AUTOLOADING FUNCTIONS section of the zsh manual + page zshmisc for more detailed information): + SETCOUNTER(XXenumcounter)(0) + enumerate( + myeit() The file contains just the body of the function, i.e. + there should be no line at the beginning saying mytt(function foo {) + or mytt(foo () {), and consequently no matching mytt(}) at the end. + This is the traditional zsh method. The advantage is that the + file is called exactly like a script, so can double as both. + To define a function mytt(xhead () { print -n "\033]2;$*\a"; }), + the file would just contain mytt(print -n "\033]2;$*\a"). + myeit() The file contains the entire definition, and maybe even + other code: it is run when the function needs to be loaded, then + the function itself is called up. This is the method in ksh. + To define the same function mytt(xhead), the whole of the + usual definition should be in the file. + ) + + In old versions of zsh, before 3.0, only the first behaviour was + allowed, so you had to make sure the file found for autoload just + contained the function body. You could still define other functions + in the file with the standard form for definitions, though they + would be redefined each time you called the main function. + + In version 3.0.x, the second behaviour is activated if the file + defines the autoloaded function. Unfortunately, this is + incompatible with the old zsh behaviour which allowed you to + redefine the function when you called it. + + From version 3.1, there is an option KSHAUTOLOAD to allow full ksh + compatiblity, i.e. the function myem(must) be in the second form + above. If that is not set, zsh tries to guess which form you are + using: if the file contains only a complete definition of the + function in the second form, and nothing else apart from comments + and whitespace, it will use the function defined in the file; + otherwise, it will assume the old behaviour. The option is set + if mytt(emulate ksh) is in effect, of course. + + (A neat trick to autoload all functions in a given directory is to + include a line like mytt(autoload ~/fns/*(:t)) in .zshrc; the bit in + parentheses removes the directory part of the filenames, leaving + just the function names.) + + +sect(How does base arithmetic work?) + + The ksh syntax is now understood, i.e. + verb( + let 'foo = 16#ff' + ) + or equivalently + verb( + (( foo = 16#ff )) + ) + or even + verb( + foo=$[16#ff] + ) + (note that `foo=$((16#ff))' is now supported). The original syntax was + verb( + (( foo = [16]ff )) + ) + --- this was based on a misunderstanding of the ksh manual page. It + still works but its use is deprecated. Then + verb( + echo $foo + ) + gives the answer `255'. It is possible to declare variables explicitly + to be integers, via + verb( + typeset -i foo + ) + which has a different effect: namely the base used in the first + assignment (hexadecimal in the example) is subsequently used whenever + `foo' is displayed (although the internal representation is unchanged). + To ensure foo is always displayed in decimal, declare it as + verb( + typeset -i 10 foo + ) + which requests base 10 for output. You can change the output base of an + existing variable in this fashion. Using the mytt($(( ... ))) method will + always display in decimal. + + +sect(How do I get a newline in my prompt?) + + You can place a literal newline in quotes, i.e. + verb( + PROMPT="Hi Joe, + what now?%# " + ) + If you have the bad taste to set the option cshjunkiequotes, which + inhibits such behaviour, you will have to bracket this with + mytt(unsetopt cshjunkiequotes) and mytt(setopt cshjunkiequotes), or put it + in your tt(.zshrc) before the option is set. + + Arguably the prompt code should handle `print'-like escapes. Feel + free to write this :-CHAR(41). Otherwise, you can use + verb( + PROMPT=$(print "Hi Joe,\nwhat now?%# ") + ) + in your initialisation file. + + +sect(Why does mytt(bindkey ^a command-name) or mytt(stty intr ^-) do something funny?) + + You probably have the extendedglob option set in which case tt(^) and tt(#) + are metacharacters. tt(^a) matches any file except one called tt(a), so the + line is interpreted as bindkey followed by a list of files. Quote the + tt(^) with a backslash or put quotation marks around tt(^a). + + +sect(Why can't I bind tt(\C-s) and tt(\C-q) any more?) + + The control-s and control-q keys now do flow control by default, + unless you have turned this off with mytt(stty -ixon) or redefined the + keys which control it with mytt(stty start) or mytt(stty stop). (This is + done by the system, not zsh; the shell simply respects these + settings.) In other words, tt(\C-s) stops all output to the terminal, + while tt(\C-q) resumes it. + + There is an option NO_FLOW_CONTROL to stop zsh from allowing flow + control and hence restoring the use of the keys: put mytt(setopt + noflowcontrol) in your tt(.zshrc) file. + + +sect(How do I execute command mytt(foo) within function mytt(foo)?) + + The command mytt(command foo) does just that. You don't need this with + aliases, but you do with functions. Note that error messages like + verb( + zsh: job table full or recursion limit exceeded + ) + are a good sign that you tried calling `foo' in function `foo' without + using `command'. If mytt(foo) is a builtin rather than an external + command, use mytt(builtin foo) instead. + + +sect(Why do history substitutions with single bangs do something funny?) + + If you have a command like "tt(echo !-2:$ !$)", the first history + substitution then sets a default to which later history substitutions + with single unqualified bangs refer, so that !$ becomes equivalent to + tt(!-2:$). The option CSH_JUNKIE_HISTORY makes all single bangs refer + to the last command. + + +sect(Why does zsh kill off all my background jobs when I logout?) + + Simple answer: you haven't asked it not to. Zsh (unlike [t]csh) gives + you the option of having background jobs killed or not: the mytt(nohup) + option exists if you don't want them killed. Note that you can always + run programs with mytt(nohup) in front of the pipeline whether or not the + option is set, which will prevent that job from being killed on + logout. (mytt(nohup) is actually an external command.) + + The mytt(disown) builtin is very useful in this respect: if zsh informs + you that you have background jobs when you try to logout, you can + mytt(disown) all the ones you don't want killed when you exit. This is + also a good way of making jobs you don't need the shell to know about + (such as commands which create new windows) invisible to the shell. + Likewise, you can start a background job with mytt(&!) instead of just + mytt(&) at the end, which will automatically disown the job. + + +sect(How do I list all my history entries?) + + Tell zsh to start from entry 1: mytt(history 1). Those entries at the + start which are no longer in memory will be silently omitted. + + +sect(How does the alternative loop syntax, e.g. mytt(while {...} {...}) \ +work?) + + Zsh provides an alternative to the traditional sh-like forms with mytt(do), + verb( + while TEST; do COMMANDS; done + ) + allowing you to have the COMMANDS delimited with some other command + structure, often mytt({...}). The rules are quite complicated and + in most scripts it is probably safer --- and certainly more + compatible --- to stick with the sh-like rules. If you are + wondering, the following is a rough guide. + + To make it work you must make sure the TEST itself is clearly + delimited. For example, this works: + verb( + while (( i++ < 10 )) { echo i is $i; } + ) + but this does myem(not): + verb( + while let "i++ < 10"; { echo i is $i; } # Wrong! + ) + The reason is that after mytt(while), any sort of command list is valid. + This includes the whole list mytt(let "i++ < 10"; { echo i $i; }); + the parser simply doesn't know when to stop. Furthermore, it is + wrong to miss out the semicolon, as this makes the mytt({...}) part + of the argument to mytt(let). A newline behaves the same as a + semicolon, so you can't put the brace on the next line as in C. + + So when using this syntax, the test following the mytt(while) must + be wrapped up: any of mytt(((...))), mytt([[...]]), mytt({...}) or + mytt((...)) will have this effect. (They have their usual syntactic + meanings too, of course; they are not interchangeable.) Note that + here too it is wrong to put in the semicolon, as then the case + becomes identical to the preceding one: + verb( + while (( i++ < 10 )); { echo i is $i; } # Wrong! + ) + + The same is true of the mytt(if) and mytt(until) constructs: + verb( + if { true } { echo yes } else { echo no } + ) + but with mytt(for), which only needs a list of words, you can get + away with it: + verb( + for foo in a b; { echo foo is $a; bar=$foo; } + ) + since the parser knows it only needs everything up to the first + semicolon. For the same reason, there is no problem with the mytt(repeat), + mytt(case) or mytt(select) constructs; in fact, mytt(repeat) doesn't even + need the semicolon since it knows the repeat count is just one word. + + This is independent of the behaviour of the SHORTLOOPS option (see + manual), which you are in any case encouraged even more strongly not + to use in programs as it can be very confusing. + + +sect(Why is my history not being saved?) + + In zsh, you need to set three variables to make sure your history is + written out when the shell exits. For example, + verb( + HISTSIZE=200 + HISTFILE=~/.zsh_history + SAVEHIST=200 + ) + tt($HISTSIZE) tells the shell how many lines to keep internally, + tt($HISTFILE) tells it where to write the history, and tt($SAVEHIST), + the easiest one to forget, tells it how many to write out. The + simplest possibility is to set it to the same as tt($HISTSIZE) as + above. There are also various options affecting history; see the + manual. + + +chapter(The mysteries of completion) + +Programmable completion using the `compctl' command is one of the most +powerful, and also potentially confusing, features of zsh; here I give +a short introduction. There is a set of example completions supplied +with the source in Misc/compctl-examples; completion definitions for +many of the most obvious commands can be found there. + +sect(What is completion?) + + `Completion' is where you hit a particular command key (TAB is the + standard one) and the shell tries to guess the word you are typing + and finish it for you --- a godsend for long file names, in + particular, but in zsh there are many, many more possibilities than + that. + + There is also a related process, `expansion', where the shell sees + you have typed something which would be turned by the shell into + something else, such as a variable turning into its value ($PWD + becomes /home/users/mydir) or a history reference (!! becomes + everything on the last command line). In zsh, when you hit TAB it + will look to see if there is an expansion to be done; if there is, + it does that, otherwise it tries to perform completion. (You can + see if the word would be expanded --- not completed --- by TAB by + typing mytt(\C-x g), which lists expansions.) Expansion is generally + fairly intuitive and not under user control; for the rest of the + chapter I will discuss completion only. + + +sect(What sorts of things can be completed?) +label(42) + + The simplest sort is filename completion, mentioned above. Unless + you have made special arrangements, as described below, then after + you type a command name, anything else you type is assumed by the + completion system to be a filename. If you type part of a word and + hit TAB, zsh will see if it matches the first part a file name and + if it does it will automatically insert the rest. + + The other simple type is command completion, which applies + (naturally) to the first word on the line. In this case, zsh + assumes the word is some command to be executed lying in your $PATH + (or something else you can execute, like a builtin command, a + function or an alias) and tries to complete that. + + Other forms of completion have to be set up by special arrangement. + See the manual entry for compctl for a list of all the flags: you + can make commands complete variable names, user names, job names, + etc., etc. + + For example, one common use is that you have an array variable, + tt($hosts), which contains names of other machines you use frequently on + the network: + verb( + hosts=(fred.ph.ku.ac.uk snuggles.floppy-bunnies.com here.there.edu) + ) + then you can tell zsh that when you use telnet (or ftp, or ...), the + argument will be one of those names: + verb( + compctl -k hosts telnet ftp ... + ) + so that if you type mytt(telnet fr) and hit TAB, the rest of the name + will appear by itself. + + An even more powerful option to tt(compctl) (tt(-g)) is to tell zsh that + only certain sorts of filename are allowed. The argument to tt(-g) is + exactly like a glob pattern, with the usual wildcards mytt(*), mytt(?), etc. + In the compctl statement it needs to be quoted to avoid it being + turned into filenames straight away. For example, + verb( + compctl -g '*.(ps|eps)' ghostview + ) + tells zsh that if you type TAB on an argument after a ghostview + command, only files ending in mytt(.ps) or mytt(.eps) should be considered + for completion. + + A useful addition for zsh from version 3.1 is directory completion: + verb( + compctl -/ cd + ) + Before, you had to use tt(-g), but this is neater: it takes care of + things like ignoring directories beginning with a dot unless you've + typed the dot yourself, and whole directory paths are understood. + + Note that flags may be combined; if you have more than one, all the + possible completions for all of them are put into the same list, all + of them being possible completions. So + verb( + compctl -k hosts -f rcp + ) + tells zsh that rcp can have a hostname or a filename after it. (You + really need to be able to handle host:file, which is where + programmable completion comes in, see link(4.5)(45).) Also, from + version 3.1 you can always handle directories at the same time as + other files just by adding tt(-/) to the list. + + +sect(How does zsh deal with ambiguous completions?) + + Often there will be more than one possible completion: two files + start with the same characters, for example. Zsh has a lot of + flexibility for what it does here via its options. The default is + for it to beep and completion to stop until you type another + character. You can type tt(\C-D) to see all the possible completions. + (That's assuming your at the end of the line, otherwise tt(\C-D) will + delete the next character and you have to use tt(ESC-\C-D).) This can be + changed by the following options, among others: + itemize( + it() with nobeep set, that annoying beep goes away + it() with nolistbeep, beeping is only turned off for ambiguous completions + it() with autolist set, when the completion is ambiguous you get a + list without having to type tt(\C-D) + it() with listambigous, this is modified so that nothing is listed if + there is an unambiguous prefix or suffix to be inserted + it() with menucomplete set, one completion is always inserted + completely, then when you hit TAB it changes to the next, and so + on until you get back to where you started + it() with automenu, you only get the menu behaviour when you hit TAB + again on the ambiguous completion. + it() Finally, although it affects all completion lists, including + those explicitly requested, note also alwayslastprompt, which + causes the cursor to return to the line you were editing after + printing the list, provided that is short enough. + ) + Combinations of these are possible; for example, autolist and + automenu together give an intuitive combination. Note that + from version 3.1 listambiguous is set by default; if you use + autolist, you may well want to `unsetopt listambiguous'. + + +sect(How do I complete in the middle of words / just what's before the cursor?) + + Sometimes you have a word on the command-line (let's stick to file + names) which is incomplete in the middle. Normally if you hit tab + in zsh, it will simply go to the end of the word and try to complete + there. However, there are two ways of changing this. + + First, there is the option COMPLETE_IN_WORD. This tries to fill in + the word at the point of the cursor. For example, if the current + directory contains mytt(foobar), then with the option set, you can + complete mytt(fbar) to mytt(foobar) by moving the cursor to the + mytt(b) and hitting tab. + + That's not the full story, however. Sometimes you just want the + part of the word before the cursor completed. For example, the word + is mytt(/usr/loc/b), which you want to complete to mytt(/usr/local/bin). + Normally, zsh won't do this in one go because there are two bits + missing (but see below!), so you need to complete the mytt(/usr/loc) + on its own first. For this you need the function + tt(expand-or-complete-prefix): it works mostly like the usual + function bound to tab, but it ignores anything on the right of the + cursor. If you always want this behaviour (some other shells do + this), bind it to tab; otherwise put another binding, e.g. mytt(^X + TAB) in tt(~/.zshrc): + verb( + bindkey "^X^I" expand-or-complete-prefix + ) + then in the example you can move to just after mytt(/usr/loc), hit + whatever key you've just bound, move to the end, and hit tab. + (Note that AUTO_REMOVE_SLASH behaviour applies here, see the manual.) + + Even that doesn't exhaust the possibilities. Included with the + source distribution is the file tt(Functions/multicomp), a function + which you can bind as an alternative form of default completion (see + below for a description of alternative completion), e.g. + verb( + compctl -D -f + -U -Q -K multicomp + ) + and whole sequences of directories, like mytt(/usr/loc/b) or even + mytt(/u/l/b) can be completed in one go. It works best with + menucompletion if the result is ambiguous. + + +sect(How do I get started with programmable completion?) +label(45) + + Finally, the hairiest part of completion. It is possible to get zsh + to consider different completions not only for different commands, + but for different words of the same command, or even to look at + other words on the command line (for example, if the last word was a + particular flag) and decide then. + + There are really two sorts of things to worry about. The simpler is + alternative completion: that just means zsh will try one + alternative, and only if there are no possible completions try the + next. For example + verb( + compctl -g '*.ps' + -f lpr + ) + says that after lpr you'd prefer to find only mytt(.ps) files, so if + there are any, only those are used, but if there aren't any, any + old file is a possibility. You can also have a tt(+) with no flags + after it, which tells zsh that it's to treat the command like any + other if nothing was found. That's only really useful if your + default completion is fancy, i.e. you have done something with + mytt(compctl -D) to tell zsh how commands which aren't specially handled + are to have their arguments completed. + + The second sort is the hard one. Following a mytt(-x), zsh expects that + the next thing will be some completion code, which is a single + letter followed by an argument in square brackets. For example + mytt(p[1]): mytt(p) is for position, and the argument tells it to look at + position 1; that says that this completion only applies to the word + immediately after the command. You can also say mytt(p[1,3]) which says + the completion only applies to the word if it's between the first + and third words, inclusive, after the command, and so on. See the + list in the `compctl' manual entry for a list of these conditions: + some conditions take one argument in the square brackets, some two. + Usually, negative numeric arguments count backwards from the end + (for example, mytt(p[-1]) applies to the last word on the line). + + (Note the difference in the ways mytt(+) and mytt(-x) work. A mytt(+) + completion will always try and find completions for what's before + the mytt(+) first; it will only produce a list for what's after if + the first list was empty. On the other hand, if a condition for a + mytt(-x) matches, the appropriate set of completions is always used, + even if the list of completions produced is empty.) + + The condition is then followed by the flags as usual (as in link(4.2)(42)), + and possibly other condition/flag sets following a single -; the + whole lot ends with a double -- before the command name. In other + words, each extended completion section looks like this: + verb( + -x <pattern> <flags>... [ - <pattern> <flags>... ...] -- + ) + + Let's look at rcp again: this assumes you've set up tt($hosts) as above. + This uses the mytt(n[<n>,<string>]) flag, which tells zsh to look for + the tt(<n>)'th occurrence of <string> in the word, ignoring anything up + to and including that. We'll use it for completing the bits of + rcp's mytt(user@host:file) combination.

Otherwise, just + complete file names. + + +sect(And if programmable completion isn't good enough?) + + ...then your last resort is to write a shell function to do it for + you. By combining the mytt(-U) and mytt(-K func) flags you can get + almost unlimited power. The mytt(-U) tells zsh that whatever the + completion produces is to be used, even if it doesn't fit what's + there already (so that gets deleted when the completion is + inserted). The mytt(-K func) tells zsh a function name. The + function is passed the part of the word already typed, and can read + the rest of the line with mytt(read -c). It can return a set of + completions via the mytt(reply) array, and this becomes the set of + possible completions. The best way to understand this is to look at + mytt(multicomp) and other functions supplied with the zsh + distribution. + + +chapter(The future of zsh) + +sect(What bugs are currently known and unfixed? (Plus recent \ +important changes)) +label(51) + + Here are some of the more well-known ones, very roughly in + decreasing order of significance. Many of these can also be counted + against differences from ksh in question link(2.1)(21); note that \ +this applies + to the latest beta version and that simple bugs are often fixed + quite quickly. There is a file Etc/BUGS in the source distribution + with more detail. + + itemize( + it() mytt(time) is ignored with builtins and can't be used with mytt({...}). + it() mytt(set -x) (mytt(setopt xtrace)) still has a few glitches. + it() Zsh's notion of the current line number (via tt($LINENO)) is + sometimes not well handled, particularly when using functions and traps. + it() In vi mode, mytt(u) can go past the original modification point. + it() The singlelinezle option has problems with prompts containing escapes. + it() The mytt(r) command does not work inside mytt($(...)) or mytt(`...`) + expansions. (This is fixed in 3.1.) + it() mytt(typeset) handling is non-optimal, particularly with regard to + flags, and is ksh-incompatible in unpredictable ways. + it() Nested closures in extended globbing and pattern matching, such as + verb( + [[ fofo = (fo#)# ]] + ) + were not correctly handled, and there were problems with + complicated exclusions using mytt(^) or mytt(~). (These + are fixed in version 3.1.3.) + ) + + Note that a few recent changes introduce incompatibilities (these + are not bugs): + + Changes after zsh 3.0 (3.1.x is still currently in beta): + itemize( + it() The options ALWAYS_LAST_PROMPT (return to the line you were + editing after displaying completion lists) and LIST_AMBIGUOUS + (show matching files when there are several) are now set by + default. This is in response to complaints that too many zsh + features are never noticed by many users. To turn them off, + just put mytt(unsetopt alwayslastprompt listambiguous) in your + tt(.zshrc) file. + it() tt(history-search-{forward,backward}) now only find previous + lines where the first word is the same as the current one. For + example, + verb( + comp<ESC>p + ) + will find lines in the history like mytt(comp -edit emacs), but not + mytt(compress file) any more. For this reason, mytt(\M-n) and + mytt(\M-p) use tt(history-beginning-search-{forward,backward}) which + search for a line with the same prefix up to the cursor position. + It is possible to write functions which go a little closer to the + original behaviour; further changes are still possible. + it() In vi insert mode, the cursor keys no longer work. The following + will bind them: + COMMENT(-- note space after backslash --) + verb( + bindkey -M viins '^[[D' vi-backward-char '^[[C' vi-forward-char \ + '^[[A' up-line-or-history '^[[B' down-line-or-history + ) + (unless your terminal requires mytt(^[O) instead of mytt(^[[)).

Thus, + mytt($1=$2) will not work. You can use something like mytt(eval + "$1=\$2"), which should have the identical effect. + it() Signal traps established with the `trap' builtin are now called with + the environment of the caller, as in ksh, instead of as a new + function level. Traps established as functions (e.g. mytt(TRAPINT() + {...})) work as before. + it() The NO_CLOBBER option is now -C and PRINT_EXIT_VALUE -1; they used + to be the other way around. (Use of names rather than letters is + generally recommended.) + it() mytt([[) is a reserved word, hence must be separated from + other characters by whitespace; mytt({) and mytt(}) are also reserved + words if the IGNORE_BRACES option is set. + it() The option CSH_JUNKIE_PAREN has been removed: csh-like code now + always does what it looks like it does, so mytt(if ( ... ) ...) + executes the code in parentheses in a subshell. To make this + useful, the syntax expected after an mytt(if), etc., is less strict + than in other shells. + it() mytt(foo=*) does not perform globbing immediately on the right + hand side of the assignment; the old behaviour now requires the + option GLOB_ASSIGN. (mytt(foo=(*)) is and has always been the + consistent way of doing this.) + it() tt(<>) performs redirection of input and output to the specified file. + For numeric globs, you now need tt(<->). + it() The command line qualifiers tt(exec), tt(noglob), tt(command), \ + tt(-) are now + treated more like builtin commands: previously they were + syntactically special. This should make it easier to perform + tricks with them (disabling, hiding in parameters, etc.). + it() The pushd builtin has been rewritten for compatibility with other + shells. The old behavour can be achieved with a shell function. + it() The current version now uses tt(~)'s for directory stack substitution + instead of tt(=)'s. This is for consistency: all other directory + substitution (tt(~user), tt(~name), tt(~+), ...) used a tilde, while + tt(=<number>) caused problems with tt(=program) substitution. + it() The `HISTLIT' option was broken in various ways and has been removed: + the rewritten history mechanism doesn't alter history lines, making + the option unnecessary. + it() History expansion is disabled in single-quoted strings, like other + forms of expansion -- hence exclamation marks there should not be + backslashed. + it() The mytt($HISTCHARS) variable is now mytt($histchars). Currently both + are tied together for compatibility. + it() The PROMPT_SUBST option now performs backquote expansion -- hence + you should quote these in prompts.

Note it is a + description of the state of affairs as seen by the developers, it is + not a guarantee!) + + You can confirm the following by looking at the source code yourself + if necessary; there's no other definitive reference: + + Zsh uses UNIX/POSIX time_t, timeval, and tm data types for internal + date manipulations. These types either do not store year values at + all (for example, time_t is measured in seconds since midnight, Jan + 1, 1970) or store them as integer types and NOT as pairs of digits. + Thus there can be no overflows at year 2000. On some unix systems, + time_t is a 32-bit value and will overflow during the year 2038, but + more modern systems use a 64-bit time_t. + + The only input and output of dates that zsh performs for its own use + is optional history time-stamping. This is performed using time_t + values converted to long integers, which are either 32 or 64 bits, + see above. + + Note, however, that zsh does provide facilities for formatted date + output, in particular in prompt escapes such as mytt(%W) and + mytt(%D) using mytt(print -P), so it's possible that scripts written + for zsh might employ 2-digit years.

When zsh is invoked as sh it mostly +conforms to POSIX 1003.2. + +Enhanced parameter expansion features: new flags: A, @, e, W, p, f, F. +Expansions can be nested. For example, +"${${(M)${(f@)$(<builtin.pro)}:#char*}[2][(w)3]}" expands to the third +word of the second line of builtin.pro which begins with char.

This means that $1 is not set +to the signal number. Of course the TRAPxxx functions continue working +as before. + +Traps defined by the trap builtin are reset to their default values in +subshells. + +Option names can be prefixed by `no' to unset an option. +setopt no_option_name is the same as unsetopt option_name. +This change affects the output of the setopt and unsetopt +builtins when these are invoked without arguments. See +the zshoptions manual page for more explanation. + +!, {, } and [[ are now reserved words.

The new OSTYPE, MACHTYPE and +VENDOR parameters should be used instead. + +VERSION parameter is renamed to ZSH_VERSION + +exec now saves the history in interactive shells. If you do not like this +behaviour you can alias exec to 'unset HISTFILE ; exec'. + +${~spec}, ${=spec} and ${^spec} used to toggle the effect of +globsubst/shwordsplit/rcexpandparam. Now these force the corresponding +option on. ~, = or ^ can be doubled to force the relevant option off for +the substitution. + +Explicitly requested word splitting like ${=spec} or ${(s:delim:)spec} +will be executed even if the substitution is double quoted. + +The right-hand side of assignments are no longer globbed by default hence +assignment foo=* will assign '*' as a value of foo. Use the foo=( * ) +array assignment syntax to get the old behaviour. Alternatively the +GLOB_ASSIGN can be set to emulate the old behaviour but the usage of this +option is strongly discouraged and this option may be completely removed in +the future. + +foo=$bar no longer creates an array even if bar is an array. Use +foo=( $bar ) or even better, foo=( "$bar[@]" ) instead. + +When foo is an array parameter ${#foo} will always return the length of the +array even if the substitution is double quoted. ${(c)#foo} should be used +to get back the old behaviour. + +When the prompt_subst option is set prompts are fully expanded using +parameter expansion, command substitution and arithmetic expansion. +In 2.5 backquote substitution was not performed in the prompts so this +change might cause problems in some startup scripts if ` is used literally +in prompts. + +History substitution is now not performed if the history escape character +appears in a single-quoted string. This may break some interactive shell +functions which use \! in single-quoted strings. + +The UID, EUID, GID, EGID parameters can be assigned now. The assignment +executes the setuid(), seteuid(), setgid(), setegid() respectively. On +systems where setuid and seteuid is not supported these functions are +emulated using setreuid or setresuid which may result in a different +behaviour. + +Assigning the USERNAME parameter will call setuid(uid) where uid is the +user id of the specified user. + +The privileged (-p) option is automatically set on invocation if euid != uid +or egid != gid. If this option is set no user startup files are sourced. +The shell will drop privileges when this option is unset by resetting its +euid to uid and its egid to gid. + +The =number substitution for accessing the directory stack is changed to +~number to allow =command substitution when a command name begins with a +digit. + +<> is a redirection operator which opens the standard input for both +reading and writing. To match a number use <->. + +Option letters -1 and -C for PRINT_EXIT_VALUE and NO_CLOBBER are swapped: +`set -C' sets NO_CLOBBER and `set -1' sets PRINT_EXIT_VALUE. + +AUTO_PUSHD behaviour is changed. Now cd without arguments will always go +to the $HOME directory even if AUTO_PUSHD is set and PUSHD_TO_HOME is not +set. If you preferred the old behaviour you can alias cd to pushd. + +IFS word splitting with SH_WORD_SPLIT and the splitting of the input in the +read builtin has changed in cases when IFS contains characters other than +<space>, <tab>, <newline>. See the description of IFS in the zshparam +manual page for more details. + + +New features in zsh version 2.5 +------------------------------- + +Greatly expanded completion possibilities. Programmable completion +allows detailed control over what arguments of what commands can be +completed to what. See dots/zcomp in the distribution for examples. + +Expand filenames with ~ and = on the right hand side of parameter +assignments. New option MAGIC_EQUAL_SUBST to do it in all +identifier=expression arguments. + +${+name} becomes 1 or 0 if name is set or unset. ${~spec} toggles +GLOB_SUBST in substitution. Parameter substitution takes lots +of flags in the format ${(flags)name}. + +New glob qualifiers for block/character special files, times in glob +qualifiers can be in months, weeks, days, hours, minutes. Qualifiers can +work on links or on what they point to. Qualifiers separated by commas +are or-ed. + +New parameter substitution modifiers (fFwW) to repeat actions. New +option CSH_JUNKIE_HISTORY. + +New line editor functions history-beginning-search-backward, +history-beginning-search-forward, expand-or-complete-prefix, push-input, +push-line-or-edit. + +Assign to part of a string, use qualifiers on string subscription with +$foo[(qual)2,5] + +New parameters: EGID, EUID, KEYTIMEOUT + +New prompt escape sequence %_ to get constructs like for and while in +the secondary prompt. %E in prompt clears to end of screen. + +Conditional expressions in PROMPT and WATCHFMT. + +New options ALWAYS_LAST_PROMPT, ALWAYS_TO_END, AUTO_PARAM_KEYS, +COMPLETE_ALIASES, COMPLETE_IN_WORD, CSH_JUNKIE_HISTORY, GLOB_SUBST, +LIST_AMBIGUOUS, MAGIC_EQUAL_SUBST, NO_FLOW_CONTROL, PROMPT_SUBST + +New option -m to many builtins makes arguments subject to pattern +matching. + +Bindkey can now bind both key sequences and prefixes of those. You can +for example bind ESC and function keys sending ESC sequences. + +Additional options to read builtin to use in functions called by +completion. + +New options to print to sort arguments and print them in columns. + +Some additional resource limits can be specified. + +Some editor functions now work in the minibuffer. diff --git a/Etc/pubring.pgp b/Etc/pubring.pgp new file mode 100644 index 000000000..526d1a66e --- /dev/null +++ b/Etc/pubring.pgp @@ -0,0 +1,150 @@ +Type Bits KeyID Created Expires Algorithm Use +pub 2048 0x8E1E1EC1 1997-05-15 ---------- RSA Sign & Encrypt +uid Andrew Main <zefram@fysh.org> + +pub 2048 0x0FD2FDD5 1998-04-22 ---------- RSA Sign & Encrypt +uid Geoff C.

Most architectures will not require any +special instructions. + +Configuring Zsh +--------------- + +To configure zsh, from the top level directory, do the command: + ./configure + +Configure accepts several options (explained below). To display +currently available options, do the command: + ./configure --help + +Most of the interesting configuration options can be added after running +configure by editing the user configuration section of config.h and the +top level Makefile. + +Dynamic loading +--------------- + +Zsh-3.1 has support for dynamically loadable modules. To enable this run +configure with the --enable-dynamic option. Note that dynamic loading +does not work on all systems. On these systems this option will have no +effect, so it is always safe to use --enable-dynamic. When dynamic +loading is enabled, major parts of zsh (including the Zsh Line Editor) are +compiled into modules and not included into the main zsh binary. Zsh +autoloads these modules when they are required. This means that you have +to execute make install.modules before you try the newly compiled zsh +executable. + +Adding more modules +------------------- + +The zsh distribution contains several modules, in the Src/Builtins, +Src/Modules and Src/Zle directories. If you have any additional zsh +modules that you wish to compile for this version of zsh, create another +subdirectory of the Src directory and put them there. You can create +as many extra subdirectory hierarchies as you need. The subdirectories +must be actual directories; symbolic links will not work. + +If you wish to add or remove modules or module directories after you +have already run make, then after adding or removing the modules run: + make prep + +Controlling what is compiled into the main zsh binary +----------------------------------------------------- + +By default the comp1, compctl, zle, sched and rlimits modules are compiled +into non-dynamic zsh and no modules are compiled into the main binary if +dynamic loading is available. This can be overridden by creating the +Src/modules-bltin file with the list of modules which are to be compiled +into the main binary. See the zshmodules manual page for the list of +available modules. + +Compiler Options or Using a Different Compiler +---------------------------------------------- + +By default, configure will use the "gcc" compiler if found. You can use a +different compiler, or add unusual options for compiling or linking that +the "configure" script does not know about, by either editing the user +configuration section of the top level Makefile (after running configure) +or giving "configure" initial values for these variables by setting them +in the environment. Using a Bourne-compatible shell (such as sh,ksh,zsh), + +you can do that on the command line like this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the "env" program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Check Generated Files +--------------------- + +Configure will probe your system and create a "config.h" header file. +You should check the user configuration section at the beginning of +this include file. You should also examine the values (determined by +configure) of HOSTTYPE, OSTYPE, MACHTYPE, and VENDOR to make sure they +are correct. The value of these #defines's is used only to initialize +the corresponding default shell parameters. Since these shell parameters +are only for informational purposes, you can change them to whatever +you feel is appropriate. + +Also configure will create a Makefile in the top level directory as well +as in the various subdirectories. You should check the user configuration +section of the top level Makefile. + +Compiling Zsh +------------- + +After configuring, to build zsh, do the command: + make + +Installing Zsh +-------------- + +If no make/compilation errors occur, then to install the zsh binary, do +the command: + make install.bin + +Any previous copy of zsh will be renamed "zsh.old" + +To install the dynamically-loadable modules, do the command: + make install.modules + +To install the zsh man page, do the command: + make install.man + +To install the zsh info files, do the command: + make install.info + +Or alternatively, you can install all the above with the command: + make install + +"make install.info" will only move the info files into the info directory. +You will have to edit the topmost node of the info tree "dir" manually +in order to have the zsh info files available to your info reader. + +Building Zsh On Additional Architectures +---------------------------------------- + +To build zsh on additional architectures, you can do a "make distclean". +This should restore the zsh source distribution back to its original +state. You can then configure zsh as above on other architectures in +which you wish to build zsh. Or alternatively, you can use a different +build directory for each architecture. + +Using A Different Build Directory +--------------------------------- + +You can compile the zsh in a different directory from the one containing +the source code. Doing so allows you to compile it on more than one +architecture at the same time. To do this, you must use a version of +"make" that supports the "VPATH" variable, such as GNU "make". "cd" to +the directory where you want the object files and executables to go and +run the "configure" script. "configure" automatically checks for the +source code in the directory that "configure" is in. For example, + + cd /usr/local/SunOS/zsh + /usr/local/src/zsh-3.0/configure + make + +Memory Routines +--------------- + +Included in this release are alternate malloc and associated functions +which reduce memory usage on some systems. To use these, add the option + --enable-zsh-mem +when invoking "configure". + +You should check Etc/MACHINES to see if there are specific recommendations +about using the zsh malloc routines on your particular architecture. + +Debugging Routines +------------------ + +You can turn on various debugging options when invoking "configure". + +To turn on some extra checking in the memory management routines, you +can use the following options when invoking "configure". + --enable-zsh-mem-warning # turn on warnings of memory allocation errors + --enable-zsh-secure-free # turn on memory checking of free() + +If you are using zsh's memory allocation routines (--enable-zsh-mem), you +can turn on debugging of this code. This enables the builtin "mem". + --enable-zsh-mem-debug # debug zsh's memory allocators + +You can turn on some debugging information of zsh's internal hash tables. +This enables the builtin "hashinfo". + --enable-zsh-hash-debug # turn on debugging of internal hash tables + +To add some sanity checks and generate debugging information for debuggers +you can use the following option. This also disables optimization. + --enable-zsh-debug # use it if you want to debug zsh + +Startup/shutdown files +---------------------- + +Zsh has several startup/shutdown files which are in /etc by default. This +can be overriden using one of the options below when invoking "configure". + + --enable-etcdir=directory # default directory for global zsh scripts + --enable-zshenv=pathname # the full pathname of the global zshenv script + --enable-zshrc=pathname # the full pathname of the global zshrc script + --enable-zlogin=pathname # the full pathname of the global zlogin script + --enable-zprofile=pathname # the full pathname of the global zprofile script + --enable-zlogout=pathname # the full pathname of the global zlogout script + +Any startup/shutdown script can be disabled by giving the +--disable-scriptname option to "configure". The --disable-etcdir option +disables all startup/shutdown files which are not explicitely enabled. + + +Options For Configure +--------------------- + +The `configure' program accepts many options, not all of which are useful +or relevant to zsh.

The latest stable version is zsh-3.0.5. + +Installing Zsh +-------------- + +The instructions for compiling zsh are in the file INSTALL. You should +also check the file MACHINES in the subdirectory Etc to see if there +are any special instructions for your particular architecture. + +Features +-------- + +Zsh is a shell with lots of features. For a list of these, see the +file Etc/FEATURES. For more details, see the documentation. + +Documentation +------------- + +There are a number of documents about zsh in this distribution: + +Doc/Zsh/*.yo The master source for the zsh documentation is written in + yodl. Yodl is a document language written by Karel Kubat. + It is not required by zsh but but it is a nice program so + you might want to get it anyway, especially if you are a + zsh developer. It can be downloaded from + ftp://ftp.icce.rug.nl/pub/unix/yodl* + +Doc/zsh*.1 Man pages in nroff format. These will be installed + by "make install.man" or "make install". By default, + these will be installed in /usr/local/man/man1, although + you can change this with the --mandir option to configure + or editing the user configuration section of the top level + Makefile. + +Doc/zsh.texi Everything the man pages have, but in texinfo format. These + will be installed by "make install.info" or "make install". + By default, these will be installed in /usr/local/info, + although you can change this with the --infodir option to + configure or editing the user configuration section of the + top level Makefile. + +Also include in the distribution are: + +Doc/intro.ms An introduction to zsh in troff format using the ms + macros. This document explains many of the features + that make zsh more equal than other shells. + Unfortunately this is based on zsh-2.5 so some examples + may not work without changes but it is still a good + introduction. + +If you do not have the necessary tools to process these documents, +PostScript, ASCII, Info and DVI versions are available in the separate +file zsh-beta-doc.tar.gz at the archive sites listed in the META-FAQ. + +The distribution also contains a Perl script in Utils/helpfiles which +can be used to extract the descriptions of builtin commands from the +zshbuiltins manual page. See the comments at the beginning of the +script about its usage. The files created by this script can be used +by example function run-help located in the subdirectory Functions to +show information about zsh builtins and run `man' on external commands. +For this the shell variable HELPDIR should point to a directory containing +the fileles generated by the helpfiles script. run-help should be +unaliased before loading the run-help function. After that this function +will be executed by the run-help ZLE function which is by default bound +to ESC-h in emacs mode. + +Examples +-------- + +Examples of zsh startup files are located in the subdirectory +StartupFiles. Examples of zsh functions and scripts are located in +the subdirectory Functions. Examples of completion control commands +(compctl) are located in the file Misc/compctl-examples. + +Zsh FTP Sites, Web Pages, and Mailing Lists +------------------------------------------- + +The current list of zsh FTP sites, web pages, and mailing lists can be +found in the META-FAQ. A copy is included in this distribution and is +available separately at any of the zsh FTP sites. + +Common Problems and Frequently Asked Questions +---------------------------------------------- + +Zsh has a list of Frequently Asked Questions (FAQ) maintained by Peter +Stephenson <pws@zsh.org>. It covers many common problems encountered +when building, installing, and using zsh. A copy is included in this +distribution in Etc/FAQ and is available separately at any of the zsh +ftp sites. + +Zsh Maintenance and Bug Reports +------------------------------- + +Zsh is currently maintained by the members of the zsh-workers mailing list +and coordinated by Andrew Main (Zefram) <zefram@zsh.org>. Please send +any feedback and bugs reports to <zsh-workers@math.gatech.edu>. + +There is a script "reporter" in the subdirectory Util which will print +out your current shell environment/setup. If you report a bug, please +use this script and include the output from sourcing this file. This way, +the problem you are reporting can be recreated. + +You can help even more if you can reproduce the bug starting zsh with +the -f option. This skips the execution of local startup files except +/etc/zshenv. If a bug occurs only when some options set try to locate +the option which triggers the bug. + +The known bugs in zsh are listed in the file Etc/BUGS. Check this as +well as the Frequently Asked Questions (FAQ) list before sending a bug +report. Note that zsh has some features which are not compatible with +sh but these are not bugs. Most of these incompatibilities go away +when zsh is invoked as sh or ksh (e.g. using a symbolic link). + +If you send a bug report to the list and are not a subscriber, please +mention this in your message if you want a response. + +If you would like to contribute to the development and maintenance of zsh, +then you should join the zsh-workers mailing list (check the META-FAQ +for info on this).
