Hi, I'm a C++/SystemVerilog engineer at Altera, a company that makes FPGAs. I'm making proposals internally that we adopt a modern build infrastructure / tooling that allows true language agnostic build system. I'm trying to get a feel for how mature Pants is, how far off the C/C++ plugin is, and how difficult it will be to add entirely new toolchain support for EDA tools like Quartus, or simulation tools such as Modelsim.

Hi! I would say Pants is very mature and heavily supported for Python, decently for JVM, and then it’s a mixed bag after that. Specifically, C/C++ is not in heavy demand and so that plugin is more of a labor of love that is not ready for prime time (although @wide-midnight-78598 may have a better idea of its future status). As for adding new toolchains, that is well-supported via the plugin API (which is technically not stabilized, but has been pretty stable in practice for a while) or the ad-hoc tools mechanism. There is documentation, examples, and community support for that sort of thing.
