Changelog

0.3.3 - 2024-02-16

  • Add Python 3.12 and 3.13 to CI
  • Can now be imported on Python 3.13

0.3.2 - 2024-01-13

0.3.1 - 2023-09-06

  • Hypothesis >= 6.89.0 made some internal changes which broke our from_grammar(). This patch restores compatibility, and requires the new Hypothesis.

0.3.0 - 2023-09-06

  • Even more efficient generation of Python identifiers, using Hypothesis 6.84.1
  • Dropped support for Python 3.7, which is end-of-life and not supported by Hypothesis

0.2.3 - 2022-12-01

  • Actually package up the renamed grammar file this time.

0.2.2 - 2022-11-29

  • Correct the minimum required version of LibCST
  • Use importlib.resources to load the Python grammar (zip-safe)

0.2.1 - 2022-11-25

  • Use the lark package on PyPI, for Lark version 1.0+ (requires recent Hypothesis)
  • Use updated Python grammar for from_grammar(), thanks to Lark updates
  • Drop support for Python 3.6, add 3.10 and 3.11 to CI

0.2.0 - 2021-11-27

  • More efficient generation of Python identifiers
  • Workaround for CPython parser bug in 3.9.8 (#16) Yes, yet another one - still, that's why hypothesmith exists...

0.1.9 - 2021-08-19

  • Fixed rare internal error when from_node() generated misplaced except: clauses

0.1.8 - 2021-01-10

  • Now compatible with Hypothesis 5.46 and later
  • Increased diversity of examples generated by from_node()

0.1.7 - 2020-11-15

  • Adds a workaround for BPO-42218
  • Bumped Hypothesis requirement to version 5.41 or later (better internal error messages)
  • Added MANIFEST.in so the sdist includes license, tests, etc.

0.1.6 - 2020-11-01

  • Improved error messages from internal compiler errors again (BPO-42218 will be fixed in Python 3.9.1)
  • Bumped Hypothesis requirement to version 5.39 or later

0.1.5 - 2020-10-12

  • Emit additional debug info when Python fails to compile a string

0.1.4 - 2020-08-16

  • Improve handling of identifiers
  • Fix internal error in from_grammar("single_input")

0.1.3 - 2020-07-30

  • Update to latest versions of LibCST and Hypothesis, for Python 3.9 support

0.1.2 - 2020-05-17

  • Emit more debug info to diagnose a compile() issue in CPython nightly

0.1.1 - 2020-05-17

  • Emit some debug info to help diagnose a possible upstream bug in CPython nightly

0.1.0 - 2020-04-24

  • Added auto_target=True argument to the from_node() strategy.
  • Improved from_node() generation of comments and trailing whitespace.

0.0.8 - 2020-04-23

  • Added a from_node() strategy which uses LibCST to generate source code. This is a proof-of-concept rather than a robust tool, but IMO it's a pretty cool concept.

0.0.7 - 2020-04-19

  • The from_grammar() strategy now takes an auto_target=True argument, to drive generated examples towards (relatively) larger and more complex programs.

0.0.6 - 2020-04-08

  • support for non-ASCII identifiers

0.0.5 - 2019-11-27

  • Updated project metadata and started testing on Python 3.8

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.
