Issues on GitHub are very much appreciated. These can be bug reports and feature requests. Don't assume that everyone knows about a bug, please file an issue. If you don't have a GitHub account, emailing me is also acceptable (joewing@joewing.net).
Before filing an issue, please check for duplicates. If there is a duplicate, feel free to comment on the issue even if you have nothing to say other than "this also affects me". This helps prioritize.
When filing an issue, call out the version of JWM (the version, commit hash, or snapshot number). Although it's recommended that you try the newest snapshot before filing an issue, sometimes that isn't easy to do, so feel free to file the issue anyway. Most of the time, I'll know if the issue has already been fixed.
For bug reports, please try to use a configuration file as close as possible to the default JWM configuration. Please describe the program or programs affected along with their versions and provide a detailed list of steps to reproduce the problem. Keep in mind, that if I am unable to reproduce a bug, it is unlikely that I will be able to fix it. Also note that the platform you are using (processor architecture, OS, etc.) likely will not match mine. Screen shots can be helpful if there is a platform-specific or closed-source program involved.
Code contributions in the form of bug fixes and features are welcome. Please file an issue before submitting a PR and announce your intent to address the issue yourself. This allows discussion of the bug or feature and prevents duplicate work. Likewise, please announce your intent to work on existing issues. For issues that take longer than a few days to address, updating the status on the issue every few days is recommended.
JWM adheres to a fairly strict coding standard. Please take a look around and try to mimic what is already there.
For pull requests, please squash your commits into logical changes. Commits should have a meaningful commit message. It should be possible to compile and run JWM at every commit.
Although I will accept patches via email, I much prefer pull requests. A PR allows GitHub to track contributions and keeps the process in the open.
The documentation for JWM is available in "man page" form in the main JWM repository as well as online at http://joewing.net/projects/jwm . To make a correction or addition to the man page, please open a pull request. The online documentation is stored in a separate repository (joewing/www). Feel free to either open a pull request there too.
The documentation is currently only available in English. Unfortunately, I lack the resources and knowledge to keep documentation in other languages up-to-date. There would need to be some restructuring to make other languages work. If you are interested in working on documentation translations, please contact me.
As with code contributions, I recommend contacting me or filing an issue before making larger changes to allow discussion and avoid unaccepted changes.
