Contributing to Yosys F4PGA Plugins

There are a couple of guidelines when contributing to Yosys F4PGA Plugins which are listed here.

Sending

All contributions should be sent as GitHub Pull requests.

License

All software (code, associated documentation, support files, etc) in the Yosys F4PGA Plugins repository are licensed under the very permissive Apache-2.0 Licence. A copy can be found in the LICENSE file.

All new contributions must also be released under this license.

Code of Conduct

By contributing you agree to the code of conduct. We follow the open source best practice of using the Contributor Covenant for our Code of Conduct.

Sign your work

To improve tracking of who did what, we follow the Linux Kernel's "sign your work" system. This is also called a "DCO" or "Developer's Certificate of Origin".

All commits are required to include this sign off and we use the Probot DCO App to check pull requests for this.

The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as a open-source patch. The rules are pretty simple: if you can certify the below:

    Developer's Certificate of Origin 1.1

    By making a contribution to this project, I certify that:

    (a) The contribution was created in whole or in part by me and I
        have the right to submit it under the open source license
        indicated in the file; or

    (b) The contribution is based upon previous work that, to the best
        of my knowledge, is covered under an appropriate open source
        license and I have the right under that license to submit that
        work with modifications, whether created in whole or in part
        by me, under the same open source license (unless I am
        permitted to submit under a different license), as indicated
        in the file; or

    (c) The contribution was provided directly to me by some other
        person who certified (a), (b) or (c) and I have not modified
        it.

(d) I understand and agree that this project and the contribution
    are public and that a record of the contribution (including all
    personal information I submit with it, including my sign-off) is
    maintained indefinitely and may be redistributed consistent with
    this project or the open source license(s) involved.

then you just add a line saying

Signed-off-by: Random J Developer <[email protected]>

using your real name (sorry, no pseudonyms or anonymous contributions.)

You can add the signoff as part of your commit statement. For example:

git commit --signoff -a -m "Fixed some errors."

Hint: If you've forgotten to add a signoff to one or more commits, you can use the following command to add signoffs to all commits between you and the upstream master:

git rebase --signoff upstream/master
