How to integrate posh-git-sh into oh-my-zsh?

[alexya]

I want to use posh-git-sh in shell 'oh-my-zsh', but I failed. could you please give me some help?

I posted a thread in stackoverflow

The file git-prompt.sh is simply a shell script, so you can source it as usual in .zshrc.

oh-my-zsh comes with themes, usually setting the PROMPT variable. Themes have no knowledge of how posh-git-sh constructs the git status string. So if you set the PROMPT variable, it might get blown away later by a theme (or vice versa).

I examined the git prompt plugin for oh-my-zsh, and it seems that the git prompt plugin sets RPROMPT, presumably to avoid stepping on the PROMPT variable set by the theme.

I refactored a little bit, so in your .zshrc, you can easily get a posh git status indicator.

. posh-git-sh/git-prompt.sh
RPROMPT='$(__posh_git_echo)'

EDIT: Added quotes around RPROMPT value

I updated both git-prompt.sh and oh-my-zsh to latest, and the following is my .zshrc file.

export ZSH=/Users/alexya/.oh-my-zsh
ZSH_THEME="crcandy"
plugins=(git-prompt)
export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
source $ZSH/oh-my-zsh.sh
. ~/posh-git-sh/git-prompt.sh
RPROMPT=$(__posh_git_echo)

close and reopen my terminal, then go to my project folder which contains code change, I still can't get the posh-git prompt style.

This works for me for oh-my-zsh:

export ZSH=export/of/.osh-my-sh
ZSH_THEME='crcandy'
plugins=
export PATH=export/of/PATH
source $ZSH/oh-my-zsh.sh
. ~/posh-git-sh/git-prompt.sh
RPROMPT='$(__posh_git_echo)'

I think the single quotes are necessary so that the RPROMPT line actually gets run.

@lyze
Yeah, I missed the single quotes, thx. one more question,

alexya@alex-imac27 [09:12:35] [~/Source/hello_world/chef_repo] [staging *]
-> %                                                               [staging ≡ +1 ~0 -0]$

The above is the my terminal, you can see that the original git-prompt, [staging *], still exist. but I want the posh-git prompt to replace the position. I am not sure if it is by design of posh-git-sh, and it can't be approached.
I have set plugins to empty in .zshrc, the same as you.

[lyze]

By design, posh-git-sh gives you a status line [staging ≡ +1 ~0 -0], and you can put that information anywhere. The difficulty is integrating into oh-my-zsh, which isn't quite extensible as we'd like. The oh-my-zsh themes use oh-my-zsh's builtin git plugin.

The line

[09:12:35] [~/Source/hello_world/chef_repo] [staging *]

is from crcandy

PROMPT=$'%{$fg_bold[green]%}%n@%m %{$fg[blue]%}%D{[%X]} %{$reset_color%}%{$fg[white]%}[%~]%{$reset_color%} $(git_prompt_info)\
%{$fg[blue]%}->%{$fg_bold[blue]%} %#%{$reset_color%} '

ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg[green]%}["
ZSH_THEME_GIT_PROMPT_SUFFIX="]%{$reset_color%}"
ZSH_THEME_GIT_PROMPT_DIRTY=" %{$fg[red]%}*%{$fg[green]%}"
ZSH_THEME_GIT_PROMPT_CLEAN=""

The theme calls $(git_prompt_info), which is part of oh-my-zsh's git plugin. So the way to go about it seems to be by modifying the PROMPT variable.

Initial thoughts: You would have to either manually patch every theme you'd like to use to use posh-git instead, or monkey patch git_prompt_info to actually call posh-git instead. In either case you'd also have to keep in mind that the ZSH_THEME_GIT_PROMPT_* colors might be different from posh-git-sh's default colors.

[alexya]

I resolved the issue by replacing $(git_prompt_info) with $(__posh_git_echo) in crcandy.zsh-theme
Thank you very much for your help.

Tried for ages and having similar problems trying to integrate with any Prezto theme.

The themes don't put VCS info into PROMPT variable. Instead they use other variables, for example, preprompt, and the info is sourced from vcs_info.

If I try and store __posh_git_echo into a variable, I get something like % % in the output.

So this script only seems to work when used with the PROMPT variable.

[nomasprime]

Outside the function that deals with setting preprompt print -P "$(__posh_git_echo)" outputs correctly but inside the function is when I get % %.

Maybe this is common problem that people with more zsh experience run into so hopefully someone can point me in the right direction.

This was way more difficult than I expected. I ended up creating a custom theme:

PROMPT="%(?:%{$fg_bold[green]%}➜ :%{$fg_bold[red]%}➜ )"
PROMPT+=' %{$fg[cyan]%}%c%{$reset_color%}$(__posh_git_echo) '

ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg_bold[blue]%}git:(%{$fg[red]%}"
ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%} "
ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[blue]%}) %{$fg[yellow]%}✗"
ZSH_THEME_GIT_PROMPT_CLEAN="%{$fg[blue]%})"

It would be nice if this community and/or the zsh community could automate this.

I did the following:

1. created a file under .oh-my-zsh/custom: my-custom-git.zsh
2. pasted the raw content of https://github.com/lyze/posh-git-sh/blob/master/git-prompt.sh
3. added a function at the end that overrides the git_prompt_info():

git_prompt_info () {
 __posh_git_echo   
}

That solved it for me, and hopefully should work with all themes that use the built-in git_prompt_info :)
