Port package to Python 3.13

[pradal]

Update the package to Python 3.13.

[pradal]

when running

from antlr4 import *

I have the following error

ModuleNotFoundError: No module named 'typing.io'; 'typing' is not a package

typing.io has been removed in Python 3.13

pip install antlr4-python3-runtime==4.8

@brichet @cyrillemidingoyi
antlr4-python3-runtime==4.8 is not valid anymore in Python 3.13.
Need to port to recent versions of antlr

[cyrillemidingoyi]

@Christophe, So I think we need to generate all the parsers and lexers.

[pradal]

How can I do that? Could you recommend some method?

[cyrillemidingoyi]

In this readme https://github.com/AgriculturalModelExchangeInitiative/PyCrop2ML/tree/master/src/pycropml/transpiler/antlr_py#readme I put the link which explain it: https://github.com/antlr/antlr4/blob/master/doc/python-target.md

The main step, after installing the new version of antlr runtime, we run these commands:
antlr4 -Dlanguage=Python3 ExprLexer.g4
antlr4 -Dlanguage=Python3 -visitor ExprParser.g4

[pradal]

First, I install

mamba install antlr4-python3-runtime==4.13.0
mamba install antlr4-tools

Then I go to

cd PyCrop2ML/src/pycropml/transpiler/antlr_py/grammars

Then I applied the two generation steps on all the Lexer.g4 (*Lexer.g4) and all the Parsers (*Parser.g4)

[pradal]

The Python code generated by

antlr4 -Dlanguage=Python3 CSharpLexer.g4

is not valid.

[pradal]

Missing grammars (I add them)

• CPP14.g4
• R.g4

[pradal]

@cyrillemidingoyi I have regenerated the grammar files.
I Have errors but not in the grammar.
I think you will be able to understand the source better than me.

I am on the branch #271 : https://github.com/AgriculturalModelExchangeInitiative/PyCrop2ML/tree/py313

[cyrillemidingoyi]

Some parts of the generated codes contain Java instructions. I remember fixing them in the last version.

[pradal]

Yes. But this has been fixed with the latest grammars.
It seems that the last errors are linked to other things...

[pradal]

I have added the grammars that were missing. And for CSharp, I added two base classes that were not generated on Python
