Blogger here: Per https://www.pantsbuild.org/page/language-support, Pants2 has support for Go, Java, Python, and Scala (I’m counting the 3GLs only, but i spy Thrift, Protobuf too). JavaScript/TypeScript is a wished for direction. Have I got the number right?

Don't forget the shell support. I don't think that's typical to support, probably niche in use even though ~everyone has bash somewhere in their codebase, but we have had very happy reports of success with that tooling.

Yup shell is a fantastic feature

There's more support for formatters and linters of other languages coming as well. Just not necessarily fully featured language support like the others
