Development instructions

The latest version of Go is recommended for developing Go bridges, but using the previous version is fine too. Go only supports the last two releases, so anything older than that is EOL and will not work.

Since the bridges use cgo, you'll also need a C compiler and libolm-dev installed. For Signal, you can either install Rust, or just download libsignal_ffi.a from the CI to avoid the Rust dependency (see normal Signal setup instructions for that).

You should install pre-commit and run pre-commit install in the repo before committing to have linters run automatically. You can also run pre-commit run -a before pushing to lint everything. Finally, you can let GitHub actions run the linters for you after pushing, but it's usually more effort to go back and fix things at that point.

Using Linux or macOS is recommended for development. Windows is generally not a supported environment for anything, so WSL is likely necessary if you're running Windows.

A local Synapse instance is useful for testing bridges. Alternatively, you can sign up for Beeper and use bridge-manager to run local bridges against the Beeper servers (there's a convenient --local-dev flag for bbctl run).

Making pull requests

Updating the changelog file is not necessary when making a pull request. That will be done separately when a release is being made.

If you're planning on making bigger changes, you should join the Matrix room linked in the project readme and briefly explain your plan to confirm that it makes sense and is wanted.

Pull requests may be missed and/or forgotten for extended periods of time, especially if they involve more complicated changes. Feel free to remind us in the appropriate Matrix room if it seems like nothing is happening. Pinging on GitHub is not recommended.
