# multicomp() {
|
|
# Completes all manner of files given prefixes for each path segment.
|
|
# e.g. s/z/s -> src/zsh-2.4/src
|
|
#
|
|
# Usage: e.g.
|
|
# compctl -D -f + -U -Q -S '' -K multicomp
|
|
#
|
|
# Will expand glob patterns already in the word, but use complete-word,
|
|
# not TAB (expand-or-complete), or you will get ordinary glob expansion.
|
|
# Requires the -U option to compctl.
|
|
# Menucompletion is highly recommended for ambiguous matches.
|
|
# Liable to screw up escaped metacharacters royally.
|
|
# $fignore is not used: feel free to add your own bit.
|
|
|
|
