Git选项卡完成在Mac上的zsh中不起作用

Question

No matter what I try and do I can't seem to make git tab/auto completion work in my zsh shell. I've downloaded the bash-completion script and the zsh-completion one and followed the instructions, but I can't make it work.

I've reinstalled oh-my-zsh but that didn't seem to help or make any difference.

Can anyone who's got it working describe to me their setup so I can try an emulate it to get it working for me?

To be specific, what I've done so far is:

• Switched to using zsh as my default shell
• Installed oh-my-zsh
• Downloaded https://github.com/git/git/blob/master/contrib/completion/git-completion.bash and saved it in ~/.completion/git/git-completion.sh
• Downloaded https://github.com/git/git/blob/master/contrib/completion/git-completion.zsh and saved that in ~/.zsh/_git
• Added zstyle ':completion:*:*:git:*' script ~/.completion/git/git-completion.sh

No luck.

Answer 1

Actually, ZSH does know how to do git completion out of the box, but you need to turn on the completion feature itself (which from the steps you described I guess you haven't done)

Adding this to your .zshrc should be enough:

autoload -Uz compinit && compinit

After you put the line .zshrc file, don't forget to restart the shell for ZSH to pick up the new config (alternatively, you can execute the line in your current session, that'll enable autocompletion for that one session)

Here's a one-liner to both add the line and apply to current session:

echo 'autoload -Uz compinit && compinit' >> ~/.zshrc && . ~/.zshrc

PS Another answer here suggests installing the hub tool instead: although the tool is handy, it's merely a 3rd party (github community) wrapper around git. Hence, it has nothing to do with the topic of "Git completion in ZSH"

Answer 2

For the 2019 viewer:

If you use ZSH:

brew install hub

mkdir ~/.zsh and mkdir ~/.zsh/completions

Once you got your directory created and hub installed , you have to cp the hub.bash_completion.sh file to your local zsh/completion folder.
(Mine was cp /usr/local/etc/bash_completion.d/hub.bash_completion.sh ~/.zsh/completions/_hub )

Then you add the following line to your ~/.zshrc file :

fpath=(~/.zsh/completions $fpath) 
autoload -U compinit && compinit

then source ~/.zshrc and voilà ! You should have the git completion available

The answer was that I had alias git=hub in my .zshrc file. See https://github.com/github/hub for info on hub (it's awesome).

Here's a link to info about the problem I was having with hub and git completion: https://github.com/github/hub/issues/586#issuecomment-47727226

Answer 4

Turns out the problem for me wass that when installing git via homebrew, git installs its own zsh shell extension which is considerably less complete/capable than the default that oh-my-szh installs. Find out what versions your git install is and then remove the zsh autocompletions. Mine were here and deleted thusly:

rm -rf /usr/local/Cellar/git/2.28.0/share/zsh/

This is not to say that the problem could not be any one of the other answers or a combination of.

Answer 5

The same issue bothers me today. Inspired by the answers, I looked around the .zshrc and found this:

Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
Example format: plugins=(rails git textmate ruby lighthouse)
Add wisely, as too many plugins slow down shell startup.
plugins=(git)

Just comment the above line to enable the git plugin, the problem is solved. More details about the plugin can be found here: https://github.com/robbyrussell/oh-my-zsh/tree/master/plugins/git

如果没有任何帮助，请尝试使用 Homebrew brew install git /usr/local/share/zsh/site-functions/_git安装 git 后出现的符号链接/usr/local/share/zsh/site-functions/_git

Answer 7

mkdir -p ~/.zsh/completions
curl "https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.zsh" > ~/.zsh/completions/_git
chmod a+x ~/.zsh/completions/_git
cat ~/.zshrc | grep 'fpath=(~/.zsh/completions $fpath)' > /dev/null || echo 'fpath=(~/.zsh/completions $fpath)' >> ~/.zshrc
cat ~/.zshrc | grep 'autoload -Uz compinit && compinit' > /dev/null || echo 'autoload -Uz compinit && compinit' >> ~/.zshrc
source ~/.zshrc

Or just run brew install zsh-completions and follow the instructions.
