Does pants support visibility for libraries? For example:

visibility = ["//visibility:public"]

Pants does not have a visibility feature like Bazel does. Targets (including libraries) are always visible across the repo.

Ok, thanks ^_^

It's frequently requested tho and we'd love to add it!

What purpose does a visibility feature serve?

Restricting parts of your codebase to other parts, so that, for example, team B doesn't start complaining when they depend on team A's hacky util code that they never meant to be used by others and then team A makes a change that breaks team B It's similar motivation to visibility systems in other languages that aren't Python, like Java, Rust, C++. Python doesn't have visibility and relies on convention with

prefixes

What?

donoteventhinkofimporting-

prefix isn't a sufficient visibility system?

The visibility option will allow the codebase to be cleaner and be used only from the exposed interfaces.
