# A plugin to shrink directory paths for brevity and pretty-printing |
||||
|
||||
|
||||
## Examples |
||||
|
||||
For this directory tree: |
||||
``` |
||||
/home/ |
||||
me/ |
||||
foo/ |
||||
bar/ |
||||
quux/ |
||||
biz/ # The prefix b is ambiguous between bar and biz. |
||||
``` |
||||
here are the results of calling `shrink_path <option> /home/me/foo/bar/quux`: |
||||
``` |
||||
Option Result |
||||
<none> /h/m/f/ba/q |
||||
-l|--last /h/m/f/ba/quux |
||||
-s|--short /h/m/f/b/q |
||||
-t|--tilde ~/f/ba/q |
||||
-f|--fish ~/f/b/quux |
||||
``` |
||||
|
||||
|
||||
## Usage |
||||
|
||||
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. |
||||
