Hypothesis strategies for generating Python programs, something like CSmith.

This is definitely pre-alpha, but if you want to play with it feel free! You can even keep the shiny pieces when - not if - it breaks.

Get it today with pip install hypothesmith, or by cloning the GitHub repo.

You can run the tests, such as they are, with tox on Python 3.6 or later. Use tox -va to see what environments are available.

Changelog

0.0.4 - 2019-09-10

• Depends on more recent Hypothesis version, with upstreamed grammar generation.
• Improved filtering rejects fewer valid examples, finding another bug in Black.

0.0.3 - 2019-08-08

Checks validity at statement level, which makes filtering much more efficient. Improved testing, input validation, and code comments.

0.0.2 - 2019-08-07

Improved filtering and fixing of source code generated from the grammar. This version found a novel bug: "pass #\\r#\\n" is accepted by the built-in compile() and exec() functions, but not by black or lib2to3.

0.0.1 - 2019-08-06

Initial release. This is a minimal proof of concept, generating from the grammar and rejecting it if we get errors from black or tokenize. Cool, but while promising not very useful at this stage.
