@@ -58,6 +58,26 @@ between 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. For example, +[[ -n *.c(#qN) ]] tests whether there are any .c files in the current +directory. + +In prompt strings, the %N(l.true.false) conditional (line length) and +the %N<..< and %N>..> truncation operators now accept negative values +of N, which count the remaining space to the opposite margin (positive +values of N still count the space used since the start of the prompt). +In PS1 and PROMPT, this counts to the right margin, whereas in RPS1 and +RPROMPT, it counts to the left margin (not to the opposite prompt). + +Another new prompt feature is the %. escape within time strings, for +example %D{%H:%M:%S.%.}. It provides zero-padded decimal fractions of +second; by default milliseconds are shown, but the number of digits may +be indicated from 1 to 6, e.g. "%6.". (Note this is part of the +extensions to strftime() formats rather of basic prompt escapes.) + Changes between 4.2 and 5.0.0 ----------------------------- |
