如何将发布存档转换为git repo [英] How to convert release archives to git repo

问题描述

我有一个发行档案的列表:

I have a list of release archives:

MyProject-0.9.zip
MyProject-1.0.zip
MyProject-1.3.tar.gz
MyProject-2.0.tar.gz

每个文件夹都包含一个与存档同名的文件夹(不带文件扩展名)，其中包含源文件和makefile等，如下所示:

Each one contains a folder with the same name as the archive (without the file extension), which contains sources and makefiles and so on, like this:

MyProject-0.9.zip
- MyProject-0.9/
- MyProject-0.9/src/
- MyProject-0.9/src/mySrc.c
- MyProject-0.9/Makefile
- MyProject-0.9/LICENSE

我想将它们转换为git repo，每个存档一次提交.

I want to convert them into a git repo, one commit per archive.

推荐答案

这是使用bash的解决方案.

• 将发布档案的修改日期用作提交的作者日期
• 向每次提交添加一个release/version git标签
• 支持不同的存档格式
• 允许在提交之前轻松清除存档内容

脚本:

#!/bin/bash
# author:      hoijui <[e-mail]>
# copyright:   Copyright (c) 2017 hoijui
# license      GNU General Public License version 3
# description: Creates a git repository from a list of release archives.
# example:     Before using the script, we should have this directory structure:
#              * conv_dir/createGitRepoFromReleaseArchives # this script
#              * conv_dir/MyProject-1.0.0.zip              # 1. release archive
#              * conv_dir/MyProject-1.0.1.zip              # 2. release archive
#              * conv_dir/MyProject-2.0.0.tar.gz           # 3. release archive
#              * conv_dir/MyProject-2.1.0.tar.gz           # 4. release archive
#              while each of the archives should contain a dir with the same name
#              as the archive (without the file extension), for example:
#              MyProject-1.0.0.zip:
#              * MyProject-1.0.0/LICENSE
#              * MyProject-1.0.0/Makefile
#              * MyProject-1.0.0/src/mySrc.c
#              We then simply run the script:
#              > createGitRepoFromReleaseArchives
#              after which we should end up with a dir "repo" containing the git repository.
