[英]How to deal with combinations of git aliases
I have three git aliases defined in .gitconfig (with an external bash script defining a function called diff-lines):我在 .gitconfig 中定义了三个 git 别名(使用一个外部 bash 脚本定义了一个名为 diff-lines 的函数):
[alias]
diffc = diff --cached
diffnw = diff -w --ignore-cr-at-eol --ignore-all-space
diffln =!bash -c 'source $HOME/.bash_functions/diff-lines && git diff | diff-lines'
How can I define 'diffln' such that I can tell it which version of my diff aliases to use?如何定义“diffln”,以便我可以告诉它使用哪个版本的 diff 别名?
I'm looking for something to prevent me from having to define each version similar to:我正在寻找一些东西来防止我必须定义类似于以下内容的每个版本:
diffcln =!bash -c 'source $HOME/.bash_functions/diff-lines && git diffc | diff-lines'
diffnwln =!bash -c 'source $HOME/.bash_functions/diff-lines && git diffnw | diff-lines'
diffcnwln =!bash -c 'source $HOME/.bash_functions/diff-lines && git diffnw --cached | diff-lines'
etc...
Thanks to @KamilCuk for the solution.感谢@KamilCuk的解决方案。 I needed to include something/anything after the alias, and also enclose the whole alias in double quotes.我需要在别名之后包含一些东西/任何东西,并将整个别名用双引号括起来。
The full working command is this (with a default option to use git diff if no argument is provided):完整的工作命令是这样的(如果没有提供参数,则默认使用 git diff 选项):
diffln ="!bash -c 'source $HOME/.bash_functions/diff-lines && if ((!$#)); then set -- diff; fi && git $@ | diff-lines' _"
I have tried this:我试过这个:
diffln =!bash -c 'source $HOME/.bash_functions/diff-lines && git $@ | diff-lines'
and called via:并通过以下方式调用:
$ git diffln diffc
but it just gave me the default git options as if I was only calling$ git
$ git diffln diffc
但它只是给了我默认的 git 选项,就好像我只是在调用$ git
Add a something after it.在它后面添加一个东西。 Typically: bash -c "blabla" _
or bash -c "balbla" --
.通常: bash -c "blabla" _
或bash -c "balbla" --
。
The first argument after bash -c "" <here>
is $0
- the second argument is $1
. bash -c "" <here>
之后的第一个参数是$0
-第二个参数是$1
。
Also remember about quoting - put $anything
inside double quotes to prevent word splitting and filename expansions.还要记住引用 - 将$anything
放在双引号内以防止分词和文件名扩展。 But I am not sure how git handled that.但我不确定 git 是如何处理的。
diffln =!bash -c 'source "$HOME/.bash_functions/diff-lines" && git "$@" | diff-lines' _
if you want to have a "default" argument, you can:如果你想有一个“默认”参数,你可以:
diffln =!bash -c 'source "$HOME/.bash_functions/diff-lines" && if ((!$#)); then set -- diff; fi && git "$@" | diff-lines' _
