./lang/py-mypy, Optional static typing for Python

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.971, Package name: py310-mypy-0.971, Maintainer: pkgsrc-users

Add type annotations to your Python programs, and use mypy to type check them.
Mypy is essentially a Python linter on steroids, and it can catch many
programming errors by analyzing your program, without actually having to run
it. Mypy has a powerful type system with features such as type inference,
gradual typing, generics and union types.

Log message:
python: egg.mk: add USE_PKG_RESOURCES flag

This flag should be set for packages that import pkg_resources
and thus need setuptools after the build step.

Set this flag for packages that need it and bump PKGREVISION.
