Python API

It would be good if vermin can export a module-level function that accepts a code string and reports its minimum version. This allows programmatic use of vermin in Python without having to invoke the CLI.

In fact, I’m occasionally using one of your test utility functions to run vermin against short code snippets in IPython without having to create a file to store the code. However this function is in the tests package and thus is not accessible from the vermin package. Also, this test function only returns the minimum version of the code. Where to report details of each rule matched and other tips (like “You’re using potentially backported modules”) is a problem.

I will expose the visit() as well. And it is the plan to do a parsable output once the format is agreed upon.

You can actually use the config already now with detect():

>>> import vermin as V
>>> V.detect("a = long(1)")
[(2, 0), None]
>>> c = V.Config.get()
>>> c.add_exclusion("long")
>>> V.detect("a = long(1)")
[(0, 0), (0, 0)]

It’s good if the initial version only returns the minimum versions. Detail reporting may be considered in the future.
