Look into using pylib for nim

pynim/transpiler.py:visit_range(), visit_print() etc could be simplified using this library

Similar library for rust:

IMO, use it, but have a fairly strict rule about when to use it, and when not to, and then break the rule as necessary to reach the goal quicker and leave a comment each time the rule is broken.

Something like: Only use helpers for Python functionality that is not feasible to reproduce using a few lines of the target language usings its stdlib.

i.e. we should inline routines where a person would normally inline routines, and use external libs where a person would normally do it, and err slightly on the side of inlining vs invoking external code, as surely one of the goals of py2many is to show people how to (correctly..?) rewrite Python logic into other languages.

That library is still seeing a lot of development.

It looks like it will allow with open(...) and with NamedTemporaryFile() without any plugins, as it allows using Python names and (apparently) Python behaviour.

Hello, while it's sad that the original url of pylib: https://github.com/Yardanico/nimpylib is 404...

yet nimpylib is still alive and even more active! new link here -> github.com/nimpylib/pylib. [^wiki]

That library is still seeing a lot of development

Now the newly born repo has implemented quite few more Python-like features, as well as some stdlibs.

[^wiki]: here's the history if you're interested.

I'm coming when planning about this issue, and wonder if there would be some cooperation between two repos. :)

Thanks for advising us of the new project; great to see it is alive.

Unfortunately py2many is not so active at the moment.

However, I can review PRs and organise a new release of py2many if you are wanting to use it as a pre-processor of Python.

py2many has the ability for each language transpiler to add Python -> Python-like transformers, so doing print(... , end=..) -> print(... , endl=..) is trivial.

With mojo as a new entrant into this area, this idea of rewriting python stdlib from scratch without using C-API has taken a life of its own. Mojo seems to be doing it, not suprisingly in mojo. But the lack of a mojo -> python AST rewriter (I couldn't find an open source AST parser for mojo) makes it a bit harder.

When I was thinking about alternatives, Nim came to mind. Feel free to open issues if something is not working well.
