Git别名和位置参数 [英] Git alias with positional parameters

问题描述

基本上我想尝试别名：

  git文件9fa3 
  / pre> 
 
 
 ...执行命令：
  diff --name-status 9fa3 ^ 9fa3 
  
但是git似乎不能将位置参数传递给alias命令。我试过：
  [别名] 
 files =！git diff --name-status $ 1 ^ $ 1 
 files =！git diff --name-status {1} ^ {1}
  
 
 
 < 
 
 
 
退化的情况是：
  $ git echo_reverse_these_params abcde 
edcba 
  
 
解决方案
最明显的方法是使用shell函数：
  [别名] 
 files =！f（）{git diff --name-status$ 1 ^$ 1;} f
  
不处理！的别名作为Git命令;例如 commit-all = commit -a 。 
 
 
 
使用！，它在shell中以自己的命令运行，让你使用更强的魔法。 
 
Basically I'm trying to alias:
git files 9fa3
...to execute the command:
git diff --name-status 9fa3^ 9fa3
but git doesn't appear to pass positional parameters to the alias command. I have tried:
[alias]
    files = "!git diff --name-status $1^ $1"
    files = "!git diff --name-status {1}^ {1}"
...and a few others but those didn't work.

The degenerate case would be:
$ git echo_reverse_these_params a b c d e
e d c b a
...how can I make this work?
解决方案
The most obvious way is to use a shell function:
[alias]
    files = "!f() { git diff --name-status "$1^" "$1"; }; f"
An alias without ! is treated as a Git command; e.g. commit-all = commit -a. 

With the !, it's run as its own command in the shell, letting you use stronger magic like this.
