feature request: repl runs `status` when user hits enter

[jjb]

something nice the now abandoned https://github.com/thoughtbot/gitsh does is run status -sb whenever you hit enter, would be cool to do that with repl, or make it customizable.

@jjb
Would you like to work on this?

I can try! it may be (very?) hard since there isn't currently any "do something on enter" behavior (right?). Any tips for where in the code I can get started to hook in this behavior?

[spacewander]

I would recommend adding a new option: git config --global git-extras.repl.on-enter-command "status -sb"

And run it after line 42 (empty command handling):

# Get configured command to run on enter
on_enter_cmd=$(git config --get git-extras.repl.on-enter-command)
if test -n "$on_enter_cmd"; then
  eval git $on_enter_cmd
fi

This would be useful! If I may, I would tweak @spacewander 's recommendation with:

# --default to prevent Bash from exiting if config value not set (assuming option `-e` / `errexit` enabled)
on_enter_cmd=$(git config --default '' --get git-extras.repl.on-enter-command)
if test -n "$on_enter_cmd"; then
  # quote whatever is passed to `eval` so wordsplitting doesn't change the command (ie. `var='echo "some      thing"'; eval "$var"`)
  # Do not automatically add git so command is more extensible (allows for compound statements as well)
  eval "$on_enter_cmd"
fi

okay, check it out! ☝️
