在提交时如何评估Git配置？ [英] How is the Git config evaluated when commit-ing?

问题描述

我正在设置My First Git Repo并运行;

  git config --list 
  

我注意到我有多个条目用于某些配置值;

  core.autocrlf =输入
 [...] 
 core.autocrlf = false 
  

我猜这些值会翻倍，因为它们出现在多个配置文件（系统，全局，文件）中的一个以上。我的问题是，这些值中的哪一个优先？配置文件是逐行读取的，最后一个条目是在提交过程中使用的吗？

解决方案

借用MYYN，这三个地方是找到配置文件的地方：
$ b $ ul
$ GIT_DIR / config


〜/ .gitconfig（--global）

$（前缀）/ etc / gitconfig

好吧，想象一下，您可以将您的电子邮件全局设置为[e-mail]。现在，我们做一个新的回购：

  $ cd / tmp 
 $ mkdir try&& cd试试
 $ git init 
 $ git config user.email [e-mail] 
 $ touch hi 
 $ git -add。 
 $ git commit -m'bla'
  

然后，您的user.email将被设置到两个值：

  $ git config --list | grep niko.schwarz 
 user.email=[e-mail] 
 user.email=[e-mail] 
  

但是，如果您查看日志，则电子邮件地址将设置为特定于回购的电子邮件地址：

  $ git log | grep niko.schwarz 
作者：Niko Schwarz< [e-mail]> 
签名：Niko Schwarz< [e-mail]> 
  

因此，局部节拍是全局的，这是列出值的顺序。现在，随着信念的飞跃，我确实认为git config --list显示的东西顺序使后者优先。

I'm setting up My First Git Repo, and on running;

git config --list

I've noticed I've got multiple entries for certain config values;

core.autocrlf=input
[...]
core.autocrlf=false

I'm guessing these values are doubled up because they appear in more than one of the various config files (system, global, file). My question is, which of these values takes precedence? Is the config file read line by line, and the last entry taken as the one used during a commit?

解决方案

Borrowed from The MYYN, these are the three places where to find config files:

• $GIT_DIR/config
• ~/.gitconfig (--global)
• $(prefix)/etc/gitconfig

Ok, imagine you globally set your email to [e-mail]. Now, we make a new repo:

$ cd /tmp
$ mkdir try && cd try
$ git init
$ git config user.email [e-mail]
$ touch hi
$ git -add .
$ git commit -m 'bla'

Then, your user.email will be set to two values:

$ git config --list | grep niko.schwarz
user.email=[e-mail]
user.email=[e-mail]

But if you look at the log, the email address will be set to the one specific to the repo:

$ git log | grep niko.schwarz
Author: Niko Schwarz <[e-mail]>
    Signed-off-by: Niko Schwarz <[e-mail]>

Therefore, local beats global, which is the order in which the values are listed. Now, with a bit of a leap of faith, I'd indeed assume that git config --list shows things in an order that makes latter ones take precedence.
