setup: replace versioneer with setuptools_scm. Has the same problems with git-archive but is much less invasive. 2019-09-05 23:11:41 -06:00			`try:`
Don't use pkg_resources. This package is deprecated and introduces a massive amount of startup latency. On my machine with 264 installed Python packages, it reduces the time required to `import nmigen` from ~100ms to ~200ms. 2020-06-30 16:08:59 -06:00			`from importlib import metadata as importlib_metadata # py3.8+ stdlib`

Add versioneer. 2019-05-26 05:20:13 -06:00
Explicitly restrict prelude imports. It turns out that while Python does not import _private identifiers when using * imports, it does nevertheless import all submodules. Avoid polluting the namespace in the prelude by explicitly listing all exported identifiers. 2019-10-21 04:39:21 -06:00
Clean up imports. This commit: * moves lists of universally useful imports from `nmigen` to `nmigen.hdl` and `nmigen.lib`, reimporting them in `nmigen`; * replaces lots of imports from individual parts of `nmigen.hdl` with a star import from `nmigen.hdl`; * replaces imports in tests with what we expect downstream code to use; * adds some missing imports in `nmigen.formal`. 2019-06-04 02:18:50 -06:00			`from .hdl import *`
