Felipe Contreras对Git补全功能(参见Git 2.30中的Zsh补全)非常积极，他提出(可能是Git 2.31, Q1 2021)一个公共函数将有助于别名自动补全。

他的建议:

Back in 2012 I argued for the introduction of a helper that would allow users to specify aliases like: git_complete gf git_fetch Back then there was pushback because there was no clear guideline for public functions (git_complete vs _git_complete vs _GIT_complete), and some aliases didn't actually work. Fast-forward to 2020 and there's still no guideline for public functions, and those aliases still don't work (even though I sent the fixes). This has not prevented people from using this function that is clearly needed to setup custom aliases (this page), and in fact it's the recommended way. But it is cumbersome that the user must type: __git_complete gf _git_fetch Or worse: __git_complete gk __gitk_main 8 years is more than enough time to stop waiting for the perfect to come; let's define a public function (with the same name) that is actually user-friendly: __git_complete gf git_fetch __git_complete gk gitk While also maintaining backwards compatibility. The logic is: If $2 exists, use it directly If not, check if __$2_main exists If not, check if _$2 exists If not, fail

这个论坛页面展示了一个解决方案。

把这些行放到你的.bashrc或.bash_profile中:

# Author.: Ole J

# Wraps a completion function
# make-completion-wrapper <actual completion function> <name of new func.>
#                         <command name> <list supplied arguments>
# eg.
#   alias agi='apt-get install'
#   make-completion-wrapper _apt_get _apt_get_install apt-get install
# defines a function called _apt_get_install (that's $2) that will complete
# the 'agi' alias. (complete -F _apt_get_install agi)
#
function make-completion-wrapper () {
    local function_name="$2"
    local arg_count=$(($#-3))
    local comp_function_name="$1"
    shift 2
    local function="
function $function_name {
    ((COMP_CWORD+=$arg_count))
    COMP_WORDS=( "$@" \${COMP_WORDS[@]:1} )
    "$comp_function_name"
    return 0
}"
    eval "$function"
}

# and now the commands that are specific to this SO question

alias gco='git checkout'

# we create a _git_checkout_mine function that will do the completion for "gco"
# using the completion function "_git"
make-completion-wrapper _git _git_checkout_mine git checkout

# we tell bash to actually use _git_checkout_mine to complete "gco"
complete -o bashdefault -o default -o nospace -F _git_checkout_mine gco

这个解决方案类似于balshetzer的脚本，但只有这个对我有效。(巴尔谢策的脚本对我的一些别名有问题。)

在git-completion。Bash有一行:

complete -o default -o nospace -F _git git

查看这一行(和_git函数)，你可以将这一行添加到你的.bash_profile:

complete -o default -o nospace -F _git_checkout gco

如上面的评论所述，

complete -o default -o nospace -F _git_checkout gco

将不再工作。然而，在git-completion中有一个__git_complete函数。Bash可以用来为别名设置补全，如下所示:

__git_complete gco _git_checkout

您可以将Tab绑定到alias-expand-line并在~/.inputrc中完成(它的默认动作)。要做到这一点，你首先需要将每个动作绑定到一个键，然后将它们链接在一起:

"\M-z":alias-expand-line
"\M-x":complete
TAB:"\M-z\M-x"

你可以使用任何你喜欢的组合键，我使用元键，因为它是免费的。更多信息见男子3阅读线。

现在，如果你打开一个新终端，输入别名:

gco m<TAB>

线路将被改造成

git checkout master

当然，即使不涉及别名，Tab也将照常工作。

我知道这个问题是关于bash的，但如果你使用zsh，这个改变@hesky-fisher回答将修复它。

From

# For each defined alias, extract the necessary elements and use them
# to call wrap_alias.
eval "$(alias -p | sed -e 's/alias \([^=][^=]*\)='\''\([^ ][^ ]*\) *\(.*\)'\''/wrap_alias \1 \2 '\''\3'\'' /')"

to:

# For each defined alias, extract the necessary elements and use them
# to call wrap_alias.
eval "$(alias | sd '^([^=]+)=(.+)' 'wrap_alias $1=$2')"

你需要sd(这可以用sed代替，但sd在我看来更好)

这样做是因为zsh没有别名-p，并且zsh中的别名输出不输出

alias <something>=<value>

就像在狂欢，但是

<something>=<value>

顺便说一下，我把初始化代码放在。zlogin文件中
