``prompt_pwd`` is a function to print the current working directory in a way suitable for prompts. It will replace the home directory with "~" and shorten every path component but the last to a default of one character.
To change the number of characters per path component, set ``$fish_prompt_pwd_dir_length`` to the number of characters. Setting it to 0 or an invalid value will disable shortening entirely.
To change the number of characters per path component, pass ``--dir-length=`` or set ``$fish_prompt_pwd_dir_length`` to the number of characters. Setting it to 0 or an invalid value will disable shortening entirely.
To keep some components unshortened, pass ``--full-length-dirs=`` or set ``$fish_prompt_pwd_full_dirs`` to the number of components.
Options
-------
- ``-h`` or ``--help`` displays the help and exits
- ``-d`` or ``--dir-length=MAX`` causes the components to be shortened to MAX characters each. This overrides $fish_prompt_pwd_dir_length.
- ``-D`` or ``--full-length-dirs=NUM`` keeps NUM components (counted from the right) as full length without shortening. This overrides $fish_prompt_pwd_full_dirs.
