是否可以根据环境变量使.gitignore可配置? [英] Is it possible to make .gitignore configurable based on environment variables?

问题描述

是否可以添加.gitignore规则取决于环境变量?

Is it possible to add to .gitignore rules depends on environment variables?

例如

if -e $(ENV_VAR) "AAA"
!liba.so
else
liba.so

---

基本上我想要的是拥有一个存储库，使得如果ENV_VAR ="AAA" ，本地存储库将具有 a.txt 和 ENV_VAR 未设置a.txt将被删除.

---

Basically what I want is to have a repository such that if ENV_VAR = "AAA" the local repository will have a.txt and if ENV_VAR isn't set the a.txt will be removed.

推荐答案

当前答案为否是，但不使用环境变量.

Currently the answer is no Yes, but not using an environment variable.

我的用例很简单；我想避免意外检查对特定文件所做的更改，以便可以在本地运行代码.

My use case is simple; I'd like to avoid accidentally checking in changes that I've made to a specific file so I can run my code locally.

假设我将我的超级秘密密码添加到 src/assets/secrets.xml 文件中，以便可以在本地运行代码，但是我从不希望密码泄露给github，这样我就可以可以使用此之类的工具找到.

Let's say I add my super secret password to the src/assets/secrets.xml file so that I can run my code locally, but I never want my password to leak to github so it can be found with tools like this.

最初，我认为能够导出GITIGNORE = path/to/that/file 的功能在这种情况下会有所帮助.

Originally I thought having the ability to export GITIGNORE=path/to/that/file would be helpful in this circumstance.

但是由于这不是一个选择，因此以下是实现相同目标的方法.

But since that's not an option, here's how to accomplish the same goal.

git update-index --assume-unchanged src/assets/secrets.xml

要取消此效果，请执行以下操作:

To undo this effect:

git update-index --no-assume-unchanged src/assets/secrets.xml

在重新阅读了OP的问题几次之后，我不确定这是否能满足他的要求.

After re-reading the OP's question a couple of times, I'm not sure if this will do what he's asking.
