RGBDS was created in the late 90's and has received contributions from several developers since then. It wouldn't have been possible to get to this point without their work and, for that reason, it is always open to the contributions of other people.
Bug reports are essential to improve RGBDS and they are always welcome. If you want to report a bug:
- Make sure that there isn't a similar issue already reported here.
- Figure out a way of reproducing it reliably.
- If there is a piece of code that triggers the bug, try to reduce it to the smallest file you can.
- Create a new issue.
Of course, it may not always be possible to give an accurate bug report, but it always helps to fix it.
If you come up with a good idea that could be implemented, you can propose it to be done.
- Create a new issue.
- Try to be as accurate as possible. Describe what you need and why you need it, maybe with examples.
Please understand that the contributors are doing it in their free time, so simple requests are more likely to catch the interest of a contributor than complicated ones. If you really need something to be done, and you think you can implement it yourself, you can always contribute to RGBDS with your own code.
If you want to contribute with your own code, whether it is to fix a current issue or to add something that nobody had requested, you should first consider if your change is going to be small (and likely to be accepted as-is) or big (and will have to go through some rework).
Big changes will most likely require some discussion, so open an issue and explain what you want to do and how you intend to do it. If you already have a prototype, it's always a good idea to show it. Tests help, too.
If you are going to work on a specific issue that involves a lot of work, it is always a good idea to leave a message, just in case someone else is interested but doesn't know that there's someone working on it.
Note that you must contribute all your changes under the MIT License. If you are just modifying a file, you don't need to do anything (maybe update the copyright years). If you are adding new files, you need to use the correct header with the copyright and the reference to the MIT License.
- Fork this repository.
- Checkout the
develop
branch. - Create a new branch to work on. You could still work on
develop
, but it's easier that way. - Compile your changes with
make develop
instead of justmake
. This target checks for additional warnings. Your patches shouldn't introduce any new warning (but it may be possible to remove some warning checks if it makes the code much easier). - Follow the Linux kernel coding style, which can be found in the file
Documentation/process/coding-style.rst
in the Linux kernel repository. Note that the coding style isn't writen on stone, if there is a good reason to deviate from it, it should be fine. - Download the files
checkpatch.pl
,const_structs.checkpatch
andspelling.txt
from the folderscripts
in the Linux kernel repository. - To use
checkpatch.pl
you can usemake checkpatch
, which will check the coding style of all patches between the current one and the upstream code. By default, the Makefile expects the script (and associate files) to be located in../linux/scripts/
, but you can place them anywhere you like as long as you specify it when executing the command:CHECKPATCH=../path/to/folder make checkpatch
. - Create a pull request against the branch
develop
. - Be prepared to get some comments about your code and to modify it. Tip: Use
git rebase -i origin/develop
to modify chains of commits.
