# shrink-path
|
|
|
|
A plugin to shrink directory paths for brevity and pretty-printing.
|
|
|
|
To use it, add `shrink-path` to the plugins array in your zshrc file:
|
|
|
|
```zsh
|
|
plugins=(... shrink-path)
|
|
```
|
|
|
|
## Examples
|
|
|
|
For this directory tree:
|
|
```
|
|
/home/
|
|
me/
|
|
f o o/ # The prefix f is ambiguous between "f o o" and "f i g".
|
|
bar/
|
|
quux/
|
|
biz/ # The prefix b is ambiguous between bar and biz.
|
|
f i g/
|
|
baz/
|
|
```
|
|
here are the results of calling `shrink_path <option> /home/me/foo/bar/quux`:
|
|
```
|
|
Option Result
|
|
<none> /h/m/f o/ba/q
|
|
-l|--last /h/m/f o/ba/q
|
|
-s|--short /h/m/f/b/q
|
|
-t|--tilde ~/f o/ba/q
|
|
-f|--fish ~/f/b/quux
|
|
-g|--glob /h*/m*/f o*/ba*/q*
|
|
-3 /hom/me/f o/bar/quu
|
|
-e '$' -3 /hom$/me/f o$/bar/quu$
|
|
-q /h/m/f\ o/ba/q
|
|
-g -q /h*/m*/f\ o*/ba*/q*
|
|
-x /home/me/foo/bar/quux
|
|
```
|
|
|
|
## Usage
|
|
|
|
For a fish-style working directory in your command prompt, add the following to
|
|
your theme or zshrc:
|
|
|
|
```zsh
|
|
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
|
|
-x, --expand Print the full path. This takes precedence over the other options
|
|
```
|
|
|
|
The long options can also be set via zstyle, like
|
|
```zsh
|
|
zstyle :prompt:shrink_path fish yes
|
|
```
|
|
|
|
Note: Directory names containing two or more consecutive spaces are not yet
|
|
supported.
|
|
|
|
|
|
## Trick: toggle shrinking with a keyboard shortcut
|
|
|
|
You can use the `expand` option to disable the path shrinking. You can combine that
|
|
with a key binding widget to toggle path shrinking on and off.
|
|
|
|
```zsh
|
|
# Toggle off path shrinking
|
|
zstyle ':prompt:shrink_path' expand true
|
|
# Toggle on path shrinking
|
|
zstyle -d ':prompt:shrink_path' expand
|
|
```
|
|
|
|
Combined with a widget:
|
|
|
|
```zsh
|
|
# Widget definition
|
|
shrink-path-toggle() {
|
|
zstyle -t ':prompt:shrink_path' expand \
|
|
&& zstyle -d ':prompt:shrink_path' expand \
|
|
|| zstyle ':prompt:shrink_path' expand true
|
|
zle reset-prompt
|
|
}
|
|
zle -N shrink-path-toggle
|
|
# Key binding to ALT+SHIFT+S
|
|
bindkey "^[S" shrink-path-toggle
|
|
```
