* Added -g option to shrink-path plugin. The new optins adds an asterix to the uniquely shortened name, such that, if copy'n'pasted, zsh globbing will expand to the full path name of the shortened path: shrink-path -g: "/net/software/modules/modulefiles" -> "/n*/s*/modules/m*" shrink-path -l -g: "/net/software/modules/modulefiles" -> "/n*/s*/modules/modulefiles" * Updated also the README file with the new -g option. * shrink-path: improved handling of special cases This commits improves the handling of special cases in path strings: - handling of white space in path names - handling of single-letter path names * Update plugins/shrink-path/README.md Co-Authored-By: Jacob Tomaw <jacob.tomaw@gmail.com> * Fix typo "Asterix" and replace with "asterisk" * Add optional quoting support to shrink_path Co-authored-by: Jacob Tomaw <jacob.tomaw@gmail.com>

# 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.
|
|
# -g, --glob Add asterisk to allow globbing of shrunk path (equivalent to -e "*")
|
|
# -l, --last Print the last directory's full name.
|
|
# -s, --short Truncate directory names to the number of characters given by -#. Without
|
|
# -s, names are truncated without making them ambiguous.
|
|
# -t, --tilde Substitute ~ for the home directory.
|
|
# -T, --nameddirs Substitute named directories as well.
|
|
# -# Truncate each directly to at least this many characters inclusive of the
|
|
# ellipsis character(s) (defaulting to 1).
|
|
# -e SYMBOL Postfix symbol(s) to indicate that a directory name had been truncated.
|
|
# -q, --quote Quote special characters in the shrunk path
|
|
#
|
|
# 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.
