I would like to hijack the python2/3 community over to guile. A first step
is a parser, it
is ontop of guile-log so you might disslike it, but that can be changed
later. I do need to develop the guile-log parser framework further so it is
logical to use it because of that. This means that currently none but me
probably can use it atm but that will change. I'm very pleased  with how
the functional parser framework works. Currently it is in hefty development
and I can't parse much python code, but that will change soon.

Stay tuned!

Oh~I could be your accomplice~ ;-P

I've rewritten guile-lua with LALR based on Guile-2.2 backend, and
passed several tests. There're few ambiguous conflicts now, but the work
is still continuing:
https://github.com/NalaGinrut/guile-lua-rebirth/blob/master/language/lua/parser.scm

Frankly, I wish I can write it with PEG. The conflicts in LALR drove me
mad, PEG would be better, in principle.
But I didn't have the chance when I started guile-lua-rebirth. Now we
have it in master!
Anyway it doesn't matter, I'll use PEG for next language front-end,
maybe Ruby, or maybe fix Ecmascript with ES6...

I confess I'm not a fan of Python, but I do appreciate that you can take
it up. Maybe we can share something in frontend, in close future. ;-)

Happy hacking!

Hi all,

Now in corona times I'm working quite a lot with python-on-guile fixing
bugs in the parser and compiler. Trying to add and test more python
modules. My test case is to get IPython running on python on guile. Some of
the python library code is very advanced python so getting it working is a
great test case. My latest addition is to generate AST from python code. I
have an AST of my own but the translation is quite transparent. I also
managed to get the python typing.py module compiling and running. That was
quite a challenge as it is quite a lot af meta programming that was hard to
get working. I also have been working hard to get autocompilation of python
code working for guile 3.0.0 and are quite happy now with it. I also
sielenced a lot of variable warnings that was wrong. So no usually those
warnings are spot on and very helpful. I will continue to work on getting
better feedback in the compiler to detect errors. I also want to see if I
can do anything with the ctypes package as well. I think the gule ffi is
comparable to ctypes. Else I will continue to see what I can do with the
ipython package.

Happy Hacking

You’re awesome! Thank you!

It sounds like the time could be coming to actually test the speed.
Maybe you can look into the pypy benchmarks for that:

https://speed.python.org/
https://speed.python.org/about/ — with link to the code

Those would give the first truly comparable test of the speed of Guile
vs. a non-Scheme — and a practical path into improving performance based
on higher level usage patterns.

Best wishes,
Arne
