The best way (the only way?) to contribute code is to submit a pull request. We have a few guidelines for you.
We love new pre-processor packages. Here are some guidelines for submitting a new pre-processor:
It should have tests. See
packages/less for examples.
It should be documented. See
It should be a stable version. If it requires an npm module install, make sure to add it to
admin/generate-dev-bundle.sh with a fixed version number. If the preprocessor is only a few files, you can avoid the dev bundle and simply put the code in the package directory.
Because the package API is still in flux, and because there are so many client-side libraries out there, we're not taking new packages that only include files to be shipped to the client at this time. You can easily get the same effect by placing the files in your application source tree. Place client library files in the directory
If you're working on a big ticket item, best to check in first on the #meteor IRC channel or email us at firstname.lastname@example.org. We'd hate to have to steer you in a different direction after you've already put in a lot of hard work.
