qua*_*nta 7 git zsh autocomplete tig
git-completion.zsh并git-completion.bash在运行时自动安装brew install git：
? 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包括在fpath：
? 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并按下tab：
? 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 中找不到这个功能

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__git_wrap_tig功能在哪里？
PS：正如我上面所说，这个问题不是每次都会发生。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
并且git完成工作按预期进行。
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
另一个调用__git_complete是在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
This is a problem with the tig completion definitions, and not with the git completion definitions.
Activating completion on tig breaks completion for git.
tig is activated after git, then tig completion works and git completion is broken.tig completion is activated before git, then they are both broken.Install the old versions of the completion scripts.
Unlink _tig and tig-completion.bash in /usr/local/share/zsh/site-functions and replace with these older versions. Rename tig-completion.zsh as _tig when downloading.
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: File issue with tig. This is a regression with the new completion script as implemented in jonas/tig#960
I start with git tab completion working, and then at some point the shell "goes bad." I actually have three states
complete not defined.
% which complete
complete
% 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 function defined referencing 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: 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
}
unsetting the complete function unset -f complete does not magically fix it. I think this may leave me with no completion for git?
I jump in and out of virtual envs, and thought that was related, but a controlled example of jumping in and out and manually setting VIRTUAL_ENV and etc did not bleed over and affect the completion system.
distraction, not related
Digging further I found a lot of local variables set in the third case, "bad shell."
I removed each of these local variables without any positive effect:
% unset REPLY
% unset __git_repo_path
% unset __tig_commands
% unset __tig_options
% unset _ack_raw_types
% unset $_cmd_variant
% unset _cmd_variant
Progress! I can move from state 1 to state 2 by invoking completion on tig:
% git <TAB>
add -- add file contents to the index
bisect -- find by binary search the change that introduced a bug
...
% tig <TAB>
% git <TAB>
__git_func_wrap:3: : not found
related broken state by completing with tig first:
% tig <TAB>
__git_complete:5: command not found: complete
% which complete
complete () {
emulate -L zsh
local args void cmd print remove
args=("$@")
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
