Mailing list


Hamlib has a very organic development model. Contributions (patches) are accepted after review and applied to the development branch (master), or, in the case of a bug fix to a released version, an arbitrary stable branch.

Patches may be submitted by one of several ways. Perhaps the most common is forking the Hamlib repository, making the changes to your cloned repository and then issuing a pull request.

Not to worry, the GitHub site (which hosts this page and repository) has plenty of help keep all of this straight.

Another way to submit patches is to post them to the mailing list where Nate, N0NB, will likely apply them and push them to the main repository. The README.developer file has some additional information.

Contributions to Hamlib come from all over the world, it seems. It is this widespread interest that keeps the project moving forward. Don’t be shy if all of this seems a bit overwhelming. All of us were beginners at some point as well.
