Dear Developers,
I'm preparing to implement a Typst printer and parser for Sympy.
I had already partially implemented the printer last year(#26814) , but it was put on hold due to academic commitments. Now, I'm hoping to participate in GSoC 2025, and here is my proposal wiki page:Implementing Typst Printer and Parser.
I'm not sure if this idea is a good fit for a GSoC proposal, and I haven't yet found a mentor to approach.
I would appreciate any feedback on the GSoC aspects as well as any suggestions regarding the printer and parser implementation.
Best regards,
Zhenxu Zhu

Hi Zhenxu,
I recommend picking either the printer or the parser as the scope, not both. Maybe you could do both in a 350 hour project, but I'm not sure.
I think lately people are trying to move to Lark as the parser tool and away from ANTLR. A project that does this for the existing ANTLR parsing would be more beneficial long term than adding a new printer/parse language.
Adding Typst support is welcome.
Jason

Hi Jason,
Thank you for your suggestions!
I understand your concerns about the overall workload. While I’m not sure about the time required for the parser, I believe I can complete the printer within 100 hours, as I’ve already finished nearly half of it last year. Given this, do you think completing both within 350 hours is reasonable?
I know that LaTeX already has a new Lark implementation. Would you recommend just using Lark instead of ANTLR for implementing a Typst parser?
After GSoC, I would also be happy to work on adding Lark implementations for existing ANTLR-based parsers.
