He moved the development from Github to Gitlab

Good move!

Why’s that? Because Github is scraping repos for Copilot?

The youtube series is quite good for this, especially the first few episodes where he uses NASM to compile from Python instead of compiling Porth with Porth.

Not to be confused with Forthon.

So a Python interpreter implemented in Forth?

That reminds me of some code I came across one time which was a BASIC implemented in Forth. It was less than 100 lines of code, which I thought was impressive.

I believe the first version of that interpreter was written by Charles Moore himself. "Lines" in Forth are rather fluid but I have a version here that is 154 lines when formatted as a text file rather than 1K disk blocks.

I read that initially as "Forthtran" and I can't tell if that sounds like a good idea or an awful one

A compiled, number crunching dialect of Forth with a very good vocabulary (and the accompanying semantics) for n-dimensions matrix calculations sounds pretty neat. I’m surprised no one jumped in with a an APL reference, however there are some significant differences between an array processing language and a concatenative language with Fortran semantics.

I'd like to know more about "certain individuals trying to disrupt the language design process" alluded to in the readme.

Alifatisk2• 4 years ago

Yeah that stuck with me as well.

I think it was basically this dude building an LLVM compiler for Porth, which made Porth's creator (Tsoding Daily) uncomfortable because he felt like he was on a race to see who made his own unfinished language better. He says individuals with an "s", so I'm not sure who else he might be talking about, but I remember this LLVM person being the big shocking reason why he initially closed the source code.

As far as I remember, the LLVM dude apologized in a public comment on the same video where Tsoding complained about this, claiming he was closing the LLVM repo and explaining it was just a toy project he made to understand LLVM better that got some attention.

This is quite stupid in my opinion. I don't see how you "help" the language discouraging others from forking/improving the project.

I am missing the python? This seems self hosting,

throwaway17_172• 4 years ago

In Tsoding’s streams Porth started out hosted via Python before he eventually wrote Porth in Porth.

There's also https://github.com/llllllllll/phorth, an implementation of forth that compiles to cpython bytecode

Playlist of this being created.

I like this HN pivot from rust to forth.
