For example, to allow '^' to be an ordinary character even if the option EXTENDED_GLOB is set, use "disable -p '^'". - + - The variable editing builtin vared can be given custom editing widgets for initialisation and finishing. - + - The line editor's capability for listening on file descriptors additional to the terminal has been enhanced so that the handler for such file descriptors can be a line editor widget. Previously the handler always behaved as a standard shell function. - + - Hooks for adding history (the function zshaddhistory and the array zshaddhistory_functions) can return status 2 to indicate that history is to be saved internally within the shell but not written. - + - In file completion, the recursive-files style can be set to an array of patterns to match against "$PWD/". In any matched location, it is possible to complete files in arbitrarily deep subdirectories without needing to type the directory prefix. See example in the zshcompsys manual. - + - The _user_expand completer now allows expansion functions in the user-expand files to return a string in REPLY that will be used to name the set of expansions returned. - + - The parameter HISTORY_IGNORE may be set to a pattern which matches lines in the internal history that are to be omitted from the history file at file write time. This differs from history changes made in the zshaddhistory hook or by the HIST_IGNORE_* options, all of which take effect immediately on the internal history list itself. - + - The parameter ZLE_RPROMPT_INDENT can be set to 0 to remove the space before the right hand side of the screen (this causes problems with some terminals). It is not special and is not set by default; the effect in that case is as if it was 1, as in previous versions. - + - If the option EXTENDED_GLOB is in effect, it is possible to force globbing within conditional code using the [[ ... ]] syntax by flagging that a certain string is a glob using the (#q) glob qualifier syntax. The resulting glob is treated as a single argument.
