prompt_pwd - Print pwd suitable for prompt
==========================================

Synopsis
--------

prompt_pwd


Description
-----------

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.

Examples
--------

::

    >_ cd ~/
    >_ echo $PWD
    /home/alfa

    >_ prompt_pwd
    ~

    >_ cd /tmp/banana/sausage/with/mustard
    >_ prompt_pwd
    /t/b/s/w/mustard

    >_ set -g fish_prompt_pwd_dir_length 3
    >_ prompt_pwd
    /tmp/ban/sau/wit/mustard
