举个例子:
我是一个在mac上的bash v3.2.17,我使用的git安装通过macports与bash_completion变体。
当我输入git checkout m<tab>。例如,我把它完成了。
然而,我有一个别名git结帐,gco。当我输入gco m<tab>时,我没有得到自动完成的分支名称。
理想情况下,我想自动完成只是神奇地为我所有的别名工作。这可能吗?如果做不到这一点,我想为每个别名手动定制它。那么,我该怎么做呢?

当前回答
我有一个别名g='git',结合我的git别名,我键入如下内容
$ g co <branchname>
对于我的特定用例,更简单的解决方法是在git-completion中添加一行代码。
就在这条线下面:
__git_complete git _git
我添加了这一行来处理我的单个'g'别名:
__git_complete g _git

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
# Date...: 23.03.2008
# License: Whatever
# 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。)
您只需要找到完整的命令并复制具有别名的行即可。
我有别名d-m=“码头机”。d-m是docker-machine的别名。
所以在Mac上(通过brew),补全文件在cd ' brew——prefix ' /etc/bash_completion.d/。 对于我的案例,我编辑了名为docker-machine的文件。 在最下面是:
complete -F _docker_machine docker-machine
所以我添加了另一行,用我的别名:
complete -F _docker_machine docker-machine
complete -F _docker_machine d-m
我也遇到了这个问题,并提出了这个代码片段。这将自动为您提供所有别名的补全。在声明所有(或任何)别名后运行它。
# wrap_alias takes three arguments:
# $1: The name of the alias
# $2: The command used in the alias
# $3: The arguments in the alias all in one string
# Generate a wrapper completion function (completer) for an alias
# based on the command and the given arguments, if there is a
# completer for the command, and set the wrapper as the completer for
# the alias.
function wrap_alias() {
[[ "$#" == 3 ]] || return 1
local alias_name="$1"
local aliased_command="$2"
local alias_arguments="$3"
local num_alias_arguments=$(echo "$alias_arguments" | wc -w)
# The completion currently being used for the aliased command.
local completion=$(complete -p $aliased_command 2> /dev/null)
# Only a completer based on a function can be wrapped so look for -F
# in the current completion. This check will also catch commands
# with no completer for which $completion will be empty.
echo $completion | grep -q -- -F || return 0
local namespace=alias_completion::
# Extract the name of the completion function from a string that
# looks like: something -F function_name something
# First strip the beginning of the string up to the function name by
# removing "* -F " from the front.
local completion_function=${completion##* -F }
# Then strip " *" from the end, leaving only the function name.
completion_function=${completion_function%% *}
# Try to prevent an infinite loop by not wrapping a function
# generated by this function. This can happen when the user runs
# this twice for an alias like ls='ls --color=auto' or alias l='ls'
# and alias ls='l foo'
[[ "${completion_function#$namespace}" != $completion_function ]] && return 0
local wrapper_name="${namespace}${alias_name}"
eval "
function ${wrapper_name}() {
let COMP_CWORD+=$num_alias_arguments
args=( \"${alias_arguments}\" )
COMP_WORDS=( $aliased_command \${args[@]} \${COMP_WORDS[@]:1} )
$completion_function
}
"
# To create the new completion we use the old one with two
# replacements:
# 1) Replace the function with the wrapper.
local new_completion=${completion/-F * /-F $wrapper_name }
# 2) Replace the command being completed with the alias.
new_completion="${new_completion% *} $alias_name"
eval "$new_completion"
}
# 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'\'' /')"
unset wrap_alias
您还可以尝试使用Git别名。例如,在我的~/。gitconfig文件,我有一个看起来像这样的部分:
[alias]
co = checkout
所以你可以输入git com <TAB>,这应该扩展到git co master,这是git checkout命令。
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
