hackett VS dmd

I am not super knowledgeable about this, but I think you might find Type Systems as Macros interesting. There is also the in-development language Hackett which uses the approach described in the paper to unify Racket style macros with a Haskell style type system.

I agree. I've been searching for solutions for a while. A few choices: - Common Lisp Coalton, very similar to Haskell. - Hackett, a Haskell-like DSL implemented in Racket. Licensing would be an issue, so it would have to be ported to Guile Scheme if you want to build an Emacs out of it. This is not easy since it takes advantage of several Racket-specific language features. - Shen, which can be built on top of Common Lisp, Scheme, Racket, or even Emacs Lisp. The drawback is that it is a fairly cryptic language, and extending foreign language bindings is not well documented. You would basically have to program the entirety of Emacs from scratch - PreScheme is a statically-typed (Hindley-Milner family) subset of Scheme that compiles to C. Originally written to build the Scheme-48 compiler, it is being ported to Guile. Not production read yet. - Zile is an editor engine built on Guile 2.0. But there is no static typing or algebraic data types, it is simply a replacement for Emacs written in Scheme from the ground-up. It needs to be ported to Guile 3.0. Guile 3 has an Emacs Lisp interpreter built-in, but it needs to be developed further before it could run more popular Emacs Lisp applications like Org-Mode or Magit.

Meh. As my final part in this exchange I will leave this here, conclusion are left to the reader: https://lexi-lambda.github.io/hackett/

My dream is something like Hackett, but alas, Alexis didn't have time to continue it. Someday ...

The documentation says it does: https://lexi-lambda.github.io/hackett/

But we can always import Coalton, or Hackett, or miniKanren into our Lisp program if we need it.

This doesn't really answer your question but you may be interested in checking out https://lexi-lambda.github.io/hackett/ by u/lexilambda.

Extremely difficult, but you can do some cool stuff with macros if you do it. Have a look at Alexis King's "Hackett" language for a cool example: https://lexi-lambda.github.io/hackett/

Here's the pipeline spitting out the same error as on my macbook did.

Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo:

https://github.com/dlang/dmd/pull/12507

https://news.ycombinator.com/item?id=27102584

A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The reference compiler, DMD, is open source: https://github.com/dlang/dmd

But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md

However, by some accounts, it's really hard to get anything through.

Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
