prompt_pwd - print pwd suitable for prompt

Synopsis

function fish_prompt
    echo -n (prompt_pwd) '$ '
end

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.

/t/b/s/w/mustard
