compctl-examples   [plain text]


#
# This file gives examples of possible programmable completions (compctl).
# You can either put the compctl commands in your .zshrc file, or put them
# in a separate file (say .zcompctl) and source it from your .zshrc file.
#
# These are just examples. Use and modify to personal taste.  Copying
# this file without thought will needlessly increase zsh's memory usage
# and startup time.
#
# For a detailed description of how these work, check the zshcompctl man
# page.

tarnames () {
	# Completion function for use with tar:
	# get the names of files in the tar archive to extract.
	#
	# The main claim to fame of this particular function is that it
	# completes directories in the tar-file in a manner very roughly
	# consistent with `compctl -f'.  There are two bugs:  first, the whole
	# path prefix up to the present is listed with ^D, not just the new
	# part to add; second, after a unique completion a space is always
	# inserted, even if the completion ends with a slash.  These are
	# currently limitations of zsh.
	#
	# This only works for the (fairly common) tar argument style where
	# the arguments are bunched into the first argument, and the second
	# argument is the name of the tarfile.  For example,
	#  tar xvzf zsh-3.1.2.tar.gz ...
