Gsoc 2026 : Parsing Fortran code to SymSy - current parser status and direction

[Jasem Manita]

Hi everyone,

I'm Jasem, intrested in "Parsing Fortran code to sympy" project, I wanted to share my findings and get feedback.

The existing fortran_parser depends on the lfortran PYPI package which is not available anymore so the entire parser is not functional. Even if the dependency were restored several core functions are either not implemented or only partially implemented.

I've been working on a replacement that uses lfortran cli (--show-asr --json) to get the ASR as json then walks the tree to produce SymPy expr . 

POC :  https://github.com/jassem-manita/Parsing-Fortran-code-to-SymPy 

My questions are : 

- should the new implementation of the Fortran Parsing idea replace the current parser or extend it ?

 -  Giver the current parser state, what contribution would be the most useful before applying ?

Thanks,

Jasem
