• py_wheel

Description

I would like use wheel version generated by other target.

Describe the solution you'd like

my_version_generator(
    name = "version"
    ...
)

py_wheel(
    name = "foo",
    version_file = ":version",
    ...
)

Solution should be a bit similiar to https://github.com/vaticle/bazel-distribution/blob/ebb4a9b342ec442c427705ec6a7919cce4c35c6e/maven/rules.bzl#L258

Describe alternatives you've considered

• Generating version before build and passing via variable in volatile status. Solution is inconvenient for multiple modules and is against bazel design.
