Hi! We'd love to have your contributions! If you want help or mentorship, reach
out to us in a GitHub issue, or ping fitzgen in #rust on irc.mozilla.org
and introduce yourself.
We abide by the Rust Code of Conduct and ask that you do as well.
To build the core library for the host target (for use with testing):
$ cargo build
To build for WebAssembly, ensure that you have the wasm32-unknown-unknown target:
$ rustup update
$ rustup target add wasm32-unknown-unknown --toolchain nightly
Then, cross compile to a .wasm file via the WebAssembly API crate:
$ cd source-map-mappings-wasm-api/
$ ./build.py -o output.wasm
The build.py script handles shrinking the size of the resulting .wasm file
for you, with wasm-gc, wasm-snip, and wasm-opt.
For more details, run:
$ ./build.py --help
The tests require cargo-readme to be installed:
$ cargo install cargo-readme
To run all the tests:
$ cargo test
We use rustfmt to enforce a
consistent code style across the whole code base.
You can install the latest version of rustfmt with this command:
$ rustup update nightly
$ cargo install -f rustfmt-nightly
Ensure that ~/.cargo/bin is on your path.
Once that is taken care of, you can (re)format all code by running this command:
$ cargo fmt
