There's genrule() which basically runs a shell script. With that, you can build anything for which you can write a command-line. And you can go as far as invoke a binary that is built by another bazel rule.

You can also define your own rules in a subset of Python (by wrapping other rules including genrule()), so adding new languages should be simple enough.

Based on my experience with bazel the phrase “should be simple enough” is doing an awful lot of work in that sentence ;)

It’s just a SMOP, right?
