[英]git completion in zsh: __git_func_wrap:3: : not found
运行brew install git
时会自动安装git-completion.zsh
和git-completion.bash
:
❯ ls -l /usr/local/share/zsh/site-functions/_git
lrwxr-xr-x 56 quanta 7 Jul 18:54 /usr/local/share/zsh/site-functions/_git -> ../../../Cellar/git/2.27.0/share/zsh/site-functions/_git
❯ ls -l /usr/local/share/zsh/site-functions/git-completion.bash
lrwxr-xr-x 71 quanta 7 Jul 18:54 /usr/local/share/zsh/site-functions/git-completion.bash -> ../../../Cellar/git/2.27.0/share/zsh/site-functions/git-completion.bash
/usr/local/share/zsh/site-functions
包含在fpath
中:
❯ echo $fpath
/usr/local/share/zsh-completions
/usr/local/share/zsh/site-functions
/usr/share/zsh/site-functions
/usr/share/zsh/5.7.1/functions
由于某些原因,有时当我输入git reba
并按tab时:
❯ git reba
__git_func_wrap:3: : not found
__git_func_wrap:3: : not found
❯ type __git_func_wrap
__git_func_wrap is a shell function from /usr/local/share/zsh/site-functions/git-completion.bash
https://github.com/git/git/blob/master/contrib/completion/git-completion.bash#L3517-L3522
❯ grep -A5 '^__git_func_wrap' /usr/local/share/zsh/site-functions/git-completion.bash
__git_func_wrap ()
{
local cur words cword prev
_get_comp_words_by_ref -n =: cur words cword prev
$1
}
默认完成是什么:
❯ complete -p git
complete -o bashdefault -o default -o nospace -F __git_wrap_tig tig
complete _bash bash
继续检查:
❯ type __git_wrap_tig
__git_wrap_tig is a shell function from /usr/local/share/zsh/site-functions/tig-completion.bash
问题是我在 tig -completion.bash中找不到这个 function

A sample of the default configuration has been installed to:
/usr/local/opt/tig/share/tig/examples/tigrc
to override the system-wide default configuration, copy the sample to:
/usr/local/etc/tigrc
Bash completion has been installed to:
/usr/local/etc/bash_completion.d
zsh completions and functions have been installed to:
/usr/local/share/zsh/site-functions
看起来最近有一些变化: https://github.com/jonas/tig/commit/26ab51d28133354bfaa94d064bff37d29b3c30e3
但是__git_wrap_tig
function在哪里?
PS:正如我上面所说,这个问题并非每次都会发生。 有时,当我打开一个新选项卡并检查默认完成时,它只是:
❯ complete -p git
complete _bash bash
和git
完成按预期工作。
回复@user1934428:
❯ grep '__git_complete ' /usr/local/share/zsh/site-functions/git-completion.bash
__git_complete ()
__git_complete git __git_main
__git_complete gitk __gitk_main
__git_complete git.exe __git_main
又一次调用__git_complete
在 tig -completion.bash中:
# we use internal git-completion functions, so wrap _tig for all necessary
# variables (like cword and prev) to be defined
__git_complete tig _tig
这是git
tig
定义的问题。
在git
tig
完成。
git
tig
激活,则git
tig
被破坏。tig
之前激活了git
完成,那么它们都被破坏了。安装旧版本的完成脚本。
在/usr/local/share/zsh/site-functions
中取消链接 _tig 和 tig-completion.bash 并替换为这些旧版本。 下载时将 tig tig-completion.zsh
重命名为_tig
。
cd /usr/local/share/zsh/site-functions && \
rm -f _tig tig-completion.bash && \
wget -O _tig https://raw.githubusercontent.com/jonas/tig/91912eb97da4f6907015dab41ef9bba315730854/contrib/tig-completion.zsh && \
wget -O tig-completion.bash https://raw.githubusercontent.com/jonas/tig/c72aa4dab21077231a97dcca8e3821d7b35fe7db/contrib/tig-completion.bash
TODO:tig 的文件问题。 这是在jonas/tig#960中实现的新完成脚本的回归
我从 git 选项卡完成工作开始,然后在某个时候 shell “变坏了”。 我实际上有三个状态
complete
未定义。 % which complete
complete
后仍在工作% git <TAB> add -- add file contents to the index bisect -- find by binary search the change that introduced a bug... % which complete complete () { return 0 }
complete
的 function 定义参考 bash complete () { emulate -L zsh local args void cmd print remove args=("$@") zparseopts -D -a void o: A: G: W: C: F: P: S: X: ab c defgjkuvp=print r=remove if [[ -n $print ]] then printf 'complete %2$s %1$s\n' "${(@kv)_comps[(R)_bash*]#* }" elif [[ -n $remove ]] then for cmd do unset "_comps[$cmd]" done else compdef _bash_complete\ ${(j. .)${(q)args[1,-1-$#]}} "$@" fi }
取消设置完整的 function unset -f complete
并不能神奇地修复它。 我认为这可能会让我无法完成 git?
我跳进跳出虚拟环境,并认为这是相关的,但是跳进和跳出并手动设置 VIRTUAL_ENV 等的受控示例并没有溢出并影响完成系统。
分心,不相关
进一步挖掘,我发现在第三种情况下设置了很多局部变量,“bad shell”。
我删除了这些局部变量中的每一个,但没有任何积极影响:
% unset REPLY
% unset __git_repo_path
% unset __tig_commands
% unset __tig_options
% unset _ack_raw_types
% unset $_cmd_variant
% unset _cmd_variant
进度:我可以通过在 tig 上调用完成从 state 1 移动到 state 2:
% git <TAB>
add -- add file contents to the index
bisect -- find by binary search the change that introduced a bug
...
% tig <TAB>
% git <TAB>
__git_func_wrap:3: : not found
通过首先完成 tig 相关损坏的 state:
% tig <TAB>
__git_complete:5: command not found: complete
% which complete
complete () {
emulate -L zsh
local args void cmd print remove
args=("$@")
zparseopts -D -a void o: A: G: W: C: F: P: S: X: a b c d e f g j k u v p=print r=remove
if [[ -n $print ]]
then
printf 'complete %2$s %1$s\n' "${(@kv)_comps[(R)_bash*]#* }"
elif [[ -n $remove ]]
then
for cmd
do
unset "_comps[$cmd]"
done
else
compdef _bash_complete\ ${(j. .)${(q)args[1,-1-$#]}} "$@"
fi
}
% git <TAB>

__git_complete
function 包含以下内容:
__git_complete ()
{
local wrapper="__git_wrap${2}"
eval "$wrapper () { __git_func_wrap $2 ; }"
}
tig 的新代码这样称呼它:
__git_complete tig _tig
此代码有效地创建了一个名为__git_wrap_tig
的包装器。
__git_wrap_tig { __git_func_wrap _tig }
但是,这些函数并不打算由 Zsh 补全使用。
Zsh 补全( 此处为最新版本)旨在自行获取 bash 补全,然后直接调用__tig_main
,绕过任何包装器。
问题是主 tig function必须称为__tig_main
,而不是_tig
。 我已经发送了一个补丁来修复这个和其他与官方 git 完成的差异。
如果您安装所有最新的相关文件:
进入您的fpath
(例如~/.zsh/
),它应该可以正常工作。
在您的评论中,您写道,您已经从https://github.com/git/git/blob/master/contrib/completion/git-completion.bash安装了完成系统,但是对于 zsh,正确的来源应该是https://github.com/git/git/blob/master/contrib/completion/git-completion.zsh
根据安装说明:git-completion.zsh 必须来源于.zshrc。 必须可以从中访问 bash 版本。
