git 可以忽略特定行吗? [英] Can git ignore a specific line?

问题描述

我正在使用 git 同步到 phonegap，同时在手机的本机浏览器上进行测试.因此，我有以下几行:

var isPhoneGap = false;

显然我在构建时更改了这一点，但是有什么方法可以设置 git 来忽略这一行，还是我必须将它放在自己的文件中并以这种方式忽略它?

我在 OSX 10.6 上使用 Gitx 和终端.

解决方案

如果您的文件属于特定类型，您可以声明一个 )

实施:

• yourFilterName.smudge(在 git checkout 上触发)和

   git config --global filter.yourFilterName.smudge 'sed "s/isPhoneGap = .*/isPhoneGap = true/''

• yourFilterName.clean(由 git add 触发)

   git config --global filter.yourFilterName.clean 'sed "s/isPhoneGap = .*/isPhoneGap = false/"'

您的文件在 git status 上看起来没有变化，但它的检出版本将具有 isPhoneGap 的正确值.

注意:在评论中, ohaal 和 Roalda> 建议在单独的 helper.sh 脚本中隔离 sed 调用:

sed "s/isPhoneGap = .*/isPhoneGap = true/";$@"

I'm using git to sync to phonegap while testing on the phone's native browser. As such I have the following line:

var isPhoneGap = false;

Obviously I change this when building, but is there any way I can set up git to ignore this one line or do I have to go and put it in its own file and ignore it that way?

I'm using Gitx and the terminal on OSX 10.6.

解决方案

If your file is of a specific type, you can declare a content filter driver, that you can declare in a .gitattributes file (as presented in the "Keyword expansion" of "Git Attributes"):

*.yourType filter=yourFilterName

(you can even set that filter for a specific file, if you want)

Implement:

• yourFilterName.smudge (triggered on git checkout) and

    git config --global filter.yourFilterName.smudge 'sed "s/isPhoneGap = .*/isPhoneGap = true/"'
  

• yourFilterName.clean (triggered on git add)

    git config --global filter.yourFilterName.clean 'sed "s/isPhoneGap = .*/isPhoneGap = false/"'
  

Your file would appear unchanged on git status, yet its checked out version would have the right value for isPhoneGap.

Note: in the comments, ohaal and Roald suggest to isolate the sed calls in a separate helper.sh script:

sed "s/isPhoneGap = .*/isPhoneGap = true/" "$@"
