Git branch with __git_ps1
Closed this issue · 6 comments
Feature Description
https://stackoverflow.com/questions/15883416/adding-git-branch-on-the-bash-command-prompt
If __git_ps1 is available (unless your git is from 2014 or before), it's shorter and less bash work than PROMPT_COMMAND='PS1_CMD1=$(git branch --show-current 2>/dev/null)'
Note that by default this will automatically generate a space and parens to produce a string like (master), so it's designed to go at the end of a prompt. It can be customized with a %s format string.

Have you noticed the Advanced Git Prompt element?
Yes, idk why PROMPT_COMMAND is necessary.
Also Idk if it's necessary to source git-prompt.sh. I never added that and I still had __git_ps1.

PROMPT_COMMAND is just a more fool-proof method of using outputs from commands in the prompt, see e.g. #20. I simply use it for every command, including Advanced Git Prompt. The git-prompt.sh script also mentions the usage of PROMPT_COMMAND for a "slightly faster prompt".

The file needs to be sourced in order to make the __git_ps1 function available in your shell. This is also stated in the official usage instructions in the git-prompt.sh script. Your git installation might have done that for you but we cannot assume that's the case for everyone.
Those are very old instructions. It now ships with git.

I have not tested with WSL or windows git bash.

This might be the case for Ubuntu, but not necessarily for other distributions – e.g. Arch Linux does not ship git-sh-prompt, it seems. Also, the Stack Exchange answer you linked still mentions that the file needs to be sourced in order to make __git_ps1 work.
Ok, I see it is sourced from git bash completion by default on ubuntu and windows git bash. https://git-scm.com/book/en/v2/Appendix-A:-Git-in-Other-Environments-Git-in-Bash
