Fish Interactive Shell full path

Question

Is there a way in the Fish Interactive shell for the full path to be displayed. Currently when I navigate to a directory I get the following shell.

millermj@Dodore ~/o/workspace

but I would rather see

millermj@Dodore ~/o-town/workspace

Answer 1

With the new fishshell (v2.3) you can do set -U fish_prompt_pwd_dir_length 0. And it will use the full path. I also use dartfish for my theme. See example below:

Here's my version of prompt_pwd that should display what you're looking for:

function prompt_pwd --description 'Print the current working directory, NOT shortened to fit the prompt'
    if test "$PWD" != "$HOME"
        printf "%s" (echo $PWD|sed -e 's|/private||' -e "s|^$HOME|~|")
    else
        echo '~'
    end

end

This will display the tilde for the home directory, as usual, but removes the sed command that only pulls the first letter from each directory when you're a few directories deep.

To edit prompt_pwd use funced. It will allow you to interactively alter the function. From the command line type funced prompt_pwd. Once the prompt is displaying to your liking, use funcsave prompt_pwd to make the behavior persist in future sessions.

I personally don't like touching the shared/defaults. Fish has a great functions design, so leverage that.

Create ~/.config/fish/functions/prompt_long_pwd.fish with the contents:

function prompt_long_pwd --description 'Print the current working directory'
        echo $PWD | sed -e "s|^$HOME|~|" -e 's|^/private||'
end

Then simply edit your ~/.config/fish/functions/fish_prompt.fish to use prompt_long_pwd. Here is the custom prompt that I use:

~/.config/fish/config.fish:

set -g __fish_git_prompt_show_informative_status 1
set -g __fish_git_prompt_hide_untrackedfiles 1

set -g __fish_git_prompt_color_branch magenta bold
set -g __fish_git_prompt_showupstream "informative"
set -g __fish_git_prompt_char_upstream_ahead "↑"
set -g __fish_git_prompt_char_upstream_behind "↓"
set -g __fish_git_prompt_char_upstream_prefix ""

set -g __fish_git_prompt_char_stagedstate "●"
set -g __fish_git_prompt_char_dirtystate "✚"
set -g __fish_git_prompt_char_untrackedfiles "…"
set -g __fish_git_prompt_char_conflictedstate "✖"
set -g __fish_git_prompt_char_cleanstate "✔"

set -g __fish_git_prompt_color_dirtystate blue
set -g __fish_git_prompt_color_stagedstate yellow
set -g __fish_git_prompt_color_invalidstate red
set -g __fish_git_prompt_color_untrackedfiles $fish_color_normal
set -g __fish_git_prompt_color_cleanstate green bold

~/.config/fish/functions/fish_prompt.fish

function fish_prompt --description 'Write out the prompt'

    set -l last_status $status

    if not set -q __fish_prompt_normal
        set -g __fish_prompt_normal (set_color normal)
    end

    # PWD
    set_color $fish_color_cwd
    echo -n (prompt_long_pwd)
    set_color normal

    printf '%s ' (__fish_git_prompt)

    if not test $last_status -eq 0
    set_color $fish_color_error
    end

    echo -n '$ '

end

Answer 4

The prompt_pwd function determines the function to be displayed. You should be able to write your own version to get what you want.
