使用格式创建'git log'别名 [英] Creating a 'git log' alias with formatting

问题描述

我已经在我的.bash_profile中设置了一堆git别名，它们可以正常工作：

 别名gst =git状态
别名gl =git pull
别名gp =git push
别名gd =git diff | mate
别名gc =git commit -v 
别名gca =git commit -v -a
别名gb =git branch
别名gba =git branch -a
  
 
 
 
我试图给以下命令添加一个别名，但仍然遇到错误：
  git log --all --pretty = format：'％h％cd％s（％an）'--since ='7 days ago'
  
我想要做的是能够输入：
  glog'一段时间'
  
新的在别名和混帐，我想这会工作：
  alias glog =git log --all --pretty =格式：'％h％cd％s（％an）'--since =
  
出现以下错误： 
 
 
  fat al：7天前的模棱两可的论点：未知的版本或路径不在工作树中。 
使用' - '分隔修订版本的路径，如下所示：
'git< command> [< revision> ...]  -  [< file>]'
  
如何纠正我的别名，使其工作？
 
 
 
谢谢！

如果我将别名更改为： 
 
 
  alias glog =git log --all --pretty = format：'％h％cd％s（％an）'
  
，然后输入： 
 
 
  glog --since ='一定数量的时间'
  
但我真的很想只输入时间量，如果可能的话。 .bash_profile 中创建一个函数。它允许你使用变量：
 
 $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ g $ -pretty = format：'％h％cd％s（％an）'--since =$ 1
} 
  

并像往常一样称呼：

  glog7天前
 
 code>

快速追踪：我将如何变更允许$​​ b $ b可能性的函数还附加了--author =so-and-so标志？例如，I
可以输入glog7天前或博客7天前--author =bob

  glog（）
 {
 if [-z $ 2];然后
 git log --all --pretty = format：'％h％cd％s（％an）'--since =$ 1
 else 
 git log --all  - -pretty = format：'％h％cd％s（％an）'--since =$ 1--author =$ 2
 fi 
} 
   $ b 
  
 glog7天前
 glog7天前bob
  
请注意，  if [-z$ 2];那么条件是检查第二个参数是否为空。如果是这样，只需执行没有 author 的代码。否则，它会使用它。
 
I have a bunch of git aliases already set up in my .bash_profile that work correctly:
alias gst="git status"
alias gl="git pull"
alias gp="git push"
alias gd="git diff | mate"
alias gc="git commit -v"
alias gca="git commit -v -a"
alias gb="git branch"
alias gba="git branch -a"
I'm trying to add an alias for the following command, but keep running into an error:
git log --all --pretty=format:'%h %cd %s (%an)' --since='7 days ago'
What I'd like to do, is be able to type:
glog 'some amount of time'
So, being new at both aliases and git, I figured this would work:
alias glog="git log --all --pretty=format:'%h %cd %s (%an)' --since="
It throws the following error:
fatal: ambiguous argument '7 days ago': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
How can I correct my alias to make this work?

Thanks!

[EDIT]

I can make it work if I change the alias to:
alias glog="git log --all --pretty=format:'%h %cd %s (%an)'"
and then just type in:
glog --since='some amount of time'
but I'd really like to just type the amount of time, if possible.
解决方案
Instead, you can create a function in .bash_profile. It will allow you to use variables:
glog ()
{
        git log --all --pretty=format:'%h %cd %s (%an)' --since="$1"
}
And call it like usual:
glog "7 days ago"





  
quick follow-up: how would I change the function to allow the
  possibility of also appending the --author="so-and-so" flag? as in, I
  could type glog "7 days ago" or blog "7 days ago" --author="bob"
I would do as like follows:
glog ()
{
    if [ -z "$2" ]; then
       git log --all --pretty=format:'%h %cd %s (%an)' --since="$1"
    else
       git log --all --pretty=format:'%h %cd %s (%an)' --since="$1" --author="$2"
    fi
}
So you can call it with
glog "7 days ago"
glog "7 days ago" "bob"
Note that the if [ -z "$2" ]; then condition is checking if the second parameter is empty.  If so, just executes the code without author. Otherwise, it uses it.
