# Shrink directory paths, e.g. /home/me/foo/bar/quux -> ~/f/b/quux.
|
|
#
|
|
# For a fish-style working directory in your command prompt, add the following
|
|
# to your theme or zshrc:
|
|
#
|
|
# setopt prompt_subst
|
|
# PS1='%n@%m $(shrink_path -f)>'
|
|
#
|
|
# The following options are available:
|
|
#
|
|
# -f, --fish fish simulation, equivalent to -l -s -t.
|
|
# -l, --last Print the last directory's full name.
|
|
# -s, --short Truncate directory names to the first character. Without
|
|
# -s, names are truncated without making them ambiguous.
|
|
# -t, --tilde Substitute ~ for the home directory.
|
|
# -T, --nameddirs Substitute named directories as well.
|
|
#
|
|
# The long options can also be set via zstyle, like
|
|
# zstyle :prompt:shrink_path fish yes
|
|
#
|
|
# Note: Directory names containing two or more consecutive spaces are not yet
|
|
# supported.
