typed-ast dependency end of life

[jbpaux]

Hi, according to this issue python/typed_ast#179 typed-ast is end of life and you should go to ast package instead

[s3v-]

typed-ast was removed from Debian sid (unstable) and trixie (testing)
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1057174
and diagrams is uninstallable consequently.

Kind Regards

Over a year on and still an issue. On Windows without the ability to build the latest typed-ast & since wheels are not available for Python 3.12 this has blocked diagrams for me.

And in fact, the typed-ast dependency isn't actually a requirement. I cloned the repo, deleted the line, and it Just Worked.

Looks like typed-ast was a requirement of the poetry tools back in the python 3.7 days, and can be simply removed now.

I can't build the typed-ast on python 3.13, which means diagrams is unusable on 3.13:

$ python --version

Oh, just noticed that it's not an issue with the more recent version of diagrams.

• 0.23.4 failed with this typed-ast issue
