Informative GIT Prompt for Fish shell

This prompt is a port of the Informative git prompt for bash which is based on Informative git prompt for zsh. Original idea is from blog post A zsh prompt for Git users.

Examples

The prompt may look like the following:

• (master↑3|✚1): on branch master, ahead of remote by 3 commits, 1 file changed but not staged
• (status|●2): on branch status, 2 files staged
• (master|✚7…): on branch master, 7 files changed, some files untracked
• (master|✖2✚3): on branch master, 2 conflicts, 3 files changed
• (experimental↓2↑3|✔): on branch experimental; your branch has diverged by 3 commits, remote by 2 commits; the repository is otherwise clean
• (:70c2952|✔): not on any branch; parent commit has hash 70c2952; the repository is otherwise clean

Prompt Structure

By default, the general appearance of the prompt is:

(<branch> <branch tracking>|<local status>)

The symbols are as follows:

• Local Status Symbols
  • ✔: repository clean
  • ●n: there are n staged files
  • ✖n: there are n unmerged files
  • ✚n: there are n changed but unstaged files
  • …n: there are n untracked files
• Branch Tracking Symbols
  • ↑n: ahead of remote by n commits
  • ↓n: behind remote by n commits
  • ↓m↑n: branches diverged, other by m commits, yours by n commits
• Branch Symbol:
  When the branch name starts with a colon :, it means it's actually a hash, not a branch (although it should be pretty clear, unless you name your branches like hashes :-)

Install

1. Move the file __informative_git_prompt.fish into ~/.config/fish/functions.
2. Configure your prompt in~/.config/fish/config.fish. For this you have to define function fish_prompt. Example function is inside example_config.fish - simply copy is enough.
3. Go in a git repository and test it!

Enjoy!

Example configuration (config.fish)

function fish_prompt --description 'Write out the prompt'

  set -l last_status $status

  set_color $fish_color_cwd
  echo -n (prompt_pwd)
  set_color normal

  __informative_git_prompt

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

  echo -n ' $ '

end
