Quick and dirty PHP svn-to-git script: it exports subversion history into git

The haremasu.php script is simply a shortcut between svn and git commands. It exports the subversion history from svn log into a temporary file, and then imports it into the locally cloned git repo.

Very quick and dirty ;-)

1. The script uses the svn and git binaries, so make sure both are available. You can check by doing a simple which svn and which git checks.

2. Start with cloning a git repo. This is where the subversion/svn revisions will be imported.

git clone [email protected]:kktsvetkov/wp-hefo.git

3. Find the subversion/svn repo URL. I advice that you get a local copy of the repo instead of using a remote one, because it will work faster.

svn checkout https://plugins.svn.wordpress.org/wp-hefo/

4. The arguments for the script are the svn url and the folder of the locally cloned git repo. If the subversion/svn project has a local copy, use its folder as the svn url.

php haremasu.php svn-url local-git-repo-folder

5. Here is what the output should look like:

php haremasu.php ~/svn.wp-hefo/ ~/github.wp-hefo/

You can see the result at https://github.com/kktsvetkov/wp-hefo/commits/master

You can export only a file or a folder from subversion/svn. You just need to use the svn source URL to point to that file or folder. Here are few examples:

php haremasu.php ~/svn.wp-hefo/trunk/hefo.php ~/github.wp-hefo/
php haremasu.php https://plugins.svn.wordpress.org/wp-hefo/tags/0.2/hefo.php ~/github.wp-hefo/
