Especially when it comes to application development, I’m a bit lazy and a general malcontent. I love solving the problem, but I hate dealing with the packaging and versioning and all of the stuff that makes something usable. One of the things I always have trouble with is keeping track of my spec file changelog when I am rolling something into an RPM.
To help ease that I put together a small script that will take a git repository’s log between any two tags and output it in a format that is acceptable in an RPM spec file.
To do this I started with the Fedora Packaging Guidelines for Changelogs. This gave me the proper formatting to adhere to for my script.
Next I used the changelog in the sosreport package for inspiration. It’s available in its spec file.
The script I wrote is designed to run inside of a git repository. If you can come up with a better way to collage this data from the .git directory then please feel free to share. So I’ve stuck it in a git repo so you can grab it if you want.
The output of my soscleaner app looks like this:

If you specify and ‘end tag’, then you won’t see the untagged commits in HEAD.
