Magic enter command for (fish) shell

Kaushik Gopal

Two of the most common commands I run when I cd into a directory are:

1. git status (which i do through git-number)
2. ls -lh (aliased automatically as ll through fish)

• If this directory is not a git repo, then I usually am thinking of command 2.
• If however it is a git repository then
  • I’d like to know if any files have been changed in this directory and
  • which ones specifically (which is command 1).

Wouldn’t it be nice if I could just hit the ↩ (enter key) and have this automatically happen?

If you’re using fish, I got you covered:

# fish/conf.d/magic-enter.fish
function magic-enter-cmd --description "Issue git status or ls on hitting enter in a dir"
    set -l cmd ll
    set -l is_git_repository (git rev-parse --is-inside-work-tree ^/dev/null) # Special variable indicating git.
    # set -l repo_has_changes (git status --porcelain --untracked-files=no)
    set -l repo_has_changes (git status --porcelain)

    if test -n "$is_git_repository"
        if test -n "$repo_has_changes"
            set cmd git status # or git-number which i highly recommend
        end
    end

    echo $cmd
end

function magic-enter
    set -l cmd (commandline)
    if test -z "$cmd"
        commandline -r (magic-enter-cmd)
        commandline -f suppress-autosuggestion
    end
    commandline -f execute
end

bind \r magic-enter
