Does anyone have any public real world examples of a pants repo that is building python, and c++ or rust ? I understand c++/rust would be via shell but visible examples would be good

I haven't used it, but there is a non-documented cc backend https://github.com/pantsbuild/pants/tree/main/src/python/pants/backend/cc

That's @wide-midnight-78598's handiwork, so would be best able to point to examples if any are public. I believe he created it for private client work, so there may not be public repos to point to (for now).

Yes of course. I have a repository of 50% python and 50% C++. With rust a potential down the track. There are some other technologies, but these are the primary. I switched the trial from Pants to Bazel and have most things working well. But pants has better python support, and the docker building experience was nicer with pants But for the c++ , bazel is kind of the answer; unless someone has done some good examples

Ah interesting. One thing you could opt to do in the interim is use both systems until Pants' C++ support is finished. Pants and Bazel can be run side by side in the same repo. You would configure Pants to use a different BUILD filename such as BUILD.pants. Then, say, configure Pants to build the Python portion of the codebase and Bazel to build the C++ side for now. It's not ideal, especially if you have a large team. But for a couple of months it could do as a workaround.

What about a shell rust / cargo example ?

We don't have Rust support yet.

Am I mistaken in thinking: any language build can be wrapped managed and cached , with work using the _shell command ?

@ancient-vegetable-10556 is the best person to answer that. I expect you'll hear from him on Monday.

@fresh-continent-76371 yes, that’s a good summary. As long as the tools used in your

_shell_command

can be found on your

PATH

, you can invoke them in the sandbox, and get caching that’s as fine-grained as the targets you define.
