typed_ast does not support parsing syntax introduced in Python 3.8 and newer, and never will. Instead, it is recommended to use the stdlib ast module in Python 3.8 and newer, which has been augmented to support extracting type comments and has some support for parsing older versions of Python 3.

This means the only valid use cases for typed_ast are a) parsing when run with Python 3.7 and older, or b) parsing Python 2.

typed_ast will continue to be maintained through Python 3.7 EOL (27 June 2023), but will likely become unmaintained soon thereafter.

Given this, we recommend:

  • Switch your project over to using ast when run on Python 3.8 or newer. Avoid installing typed_ast when running on Python 3.8 or newer by using a PEP 508 requirement, see for example.
  • If your project supports parsing Python 2, make this support an optional extra, so users do not have to install typed_ast unless they need that support, see for example. Also, y'know, consider dropping Python 2 support.

(To avoid user confusion, please discuss in #170)

Bump typed_ast 1.4.2 -> 1.4.3
2210bdc 
To get the fix for python/typed_ast#159; With
1.4.2 `typed_ast` can't be installed on recent Pythons. Note that this
 new version is still compatible with the version specifications in
`pyproject.toml`; this is "just" a `poetry update typed_ast`.

Side note: `typed_ast` is going away next July: python/typed_ast#179

Python: Avoid typed-ast dependency
87fe7e8 
The `typed-ast` package is being end-of-life'd soon. See python/typed_ast#179.
Moreover, it is causing issues when building with Python 3.11+. See
GaloisInc/cryptol#1491.  Thankfully, `typed-ast` is no longer required if you
use sufficiently new versions of `mypy` and Python. This patch raises the lower
version bounds to make it possible to shed the `typed-ast` dependency entirely.

Python: Bump argo-client, mypy versions
ea05062 
This patch:

* Bumps the `mypy` lower bounds to avoid incurring a dependency on `typed-ast`,
  which is being EOL'd soon. See python/typed_ast#179.
* Bumps the `argo` lower bounds to bring in the changes from
  GaloisInc/argo#195, which makes corresponding changes on the `argo` side.

Fixes #1491.

It's July 2023, death to typed_ast!

I did a quick check and it seems like typed_ast does work against Python 3.12 beta 2, so that could be nice for whatever users are remaining on latest Python (we're still clocking a few thousand daily downloads on 3.11). We won't ship wheels, but we didn't ship wheels for Python 3.11 either.

I'll ask the Steering Council to archive this repository.
