Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

"Check out this new language I've been working on!"
"Here's a blog post on how I implemented static type checking into this compiler"
"I want to write a compiler, where do I start?"
"How does the Java compiler work? How does it handle forward declarations/imports/targeting multiple platforms/?"
"How should I test my compiler? How are other compilers and interpreters like gcc, Java, and python tested?"
"What are the pros/cons of ?"
"Compare and contrast vs. "
"Confused about the semantics of this language"
"Proceedings from PLDI / OOPSLA / ICFP / "

See /r/ProgrammingLanguages for specific examples

From the site:

We have entered a world in which we need to do more with less. If you, like us, have frowned at the difficulty and inefficiency of creating software, and wondered if there is a better way, Meta is for you. It is a descendant of the acclaimed REBOL and Logo computer languages. Logo was designed in academia to teach programming in a simple yet powerful way. It is widely used in education and influenced many newer systems and languages. REBOL extended this concept to professional programming. It was invented by Carl Sassenrath, the chief software designer of the famous Amiga computer, the first consumer multimedia system. Meta takes the next step by combining this design with the virtues of the C programming language, which has been the standard for software interoperability and performance for half a century.

Seems to be primarily inspired by REBOL but designed to be faster [1].
Can compile to various 8-bit Atari machines and αcτµαlly pδrταblε εxεcµταblε (which means it can run on almost anything) [2].
Has an official Bluesky account, which AFAIK is the main social media presence.

REBOL is one of my biggest blind spots in programming language familiarity. I remember there was another REBOL revival project called RED, which always boasted huge feature sets with small amounts of code, though I never got around to investigating those claims myself.

This project seems to aim to provide strong foundations for a more performant compiler, but still lacks the most powerful REBOL features. I wonder if anyone can summarise those features? In particular, is there anything fundamental that distinguishes REBOL from Lisp, Smalltalk, Ruby, etc?

Also to be fully homoiconic, Meta needs to be able to manipulate its own code. Currently, that is done by REBOL 3. REBOL is homoiconic, and Meta is currently a REBOL 3 format. It will take a lot more to enable Meta to handle its own code, so that will take time. Even though REBOL and Red are homoiconic, they're not implemented in themselves. REBOL has a C interpreter and Red a Red/System interpreter. Meta is two to three orders of magnitude faster and designed to be able to implement itself eventually.
