#52(one) nice thing about Raku is it does a surprisingly good lisp impression out of the box…

Re: Hy 1.0 – Lisp dialect for Python
#53Any downsides to using Hy (over Python)? Other than my coworkers don't know Lisp? More concrete: Are there Python language features I can't use in Hy? Or performance penalties in using Hy?
Lack of self-contained tooling. Idle doesn't work with Hy. You'll probably need to fiddle with Emacs to set your environment first, before being able to do anything beyond playing with the language in the REPL.
IDLE is not designed for this, obviously. But you can debug Hy using standard Python tools.
Re: Hy 1.0 – Lisp dialect for Python
#54Congrats! Two questions: 1. Does it support REPL-driven development? (condition system, breakloop, etc.) 2. Is there a standalone distribution? Distributing python in itself is a hassle, ideal situation would be to simply distribute a single Hy binary that contains all dependencies within it (either statically linked or as a zip file extracted in tmp directory).
not a standalone distribution but: uvx hy@1.0.0 gets you into the Hy REPL echo '(print "hi hn")' > hi.hy uvx hy@1.0.0 hi.hy prints "hi hn" https://docs.astral.sh/uv/guides/tools/#running-tools (context: uv can install and manage python versions)
Generally, uv answers the objection that ‘Python sux’ in that it (1) is correct, unlike pip, and (2) is freaky fast.
Re: Hy 1.0 – Lisp dialect for Python
#55Yay! The birth of a language is a beautiful thing.
I’m curious about the macros: how are these implemented? They seem like pretty straightforward unhygienic Lisp macros, which is a little bit of a disappointment, but better some macros than none at all! Anything about the macro system that distinguishes it from the Common Lisp system? E.g. anything borrowed from Scheme or Racket? Docs are sparse here.
Re: Hy 1.0 – Lisp dialect for Python
#56I'm wondering, is it worth learning Hy if I don't know any python? (coming from a clojure background)
Or is python knowledge a prerequisite?

It’s far from new. In 2012 I worked for a shop who used an internal package named “hy”, and the introduction of this Hy made our builds break in a novel and interesting way.
(Also, use something to insure your own internal packages have a higher priority, alright? That’s a lesson I didn’t need to learn twice.)
Re: Hy 1.0 – Lisp dialect for Python
#58Super happy Hy 1.0 has been released! It was the first proper open-source project I contributed towards and I don't think I would have been as engaged as I am in the community without it.
Re: Hy 1.0 – Lisp dialect for Python
#59I was having some difficulty figuring out how Hy actually is translated to Python (and wasn't even sure if it was compiled or interpreted). Eventually I found on Wikipedia the following: > Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Also, looking at the code on Github suggests this compiler is written in Pytho…
The original hy annoucement makes it clear that they embed a Lisp by compiling with Python bytecode. You can see it in the following video about the 16:25 mark https://m.youtube.com/watch?v=1vui-LupKJI
and for those interested in history, Docker was first announced 10 minutes afterwards on the 26:24 mark.

Now I know how those guys felt who were on the same episode of Ed Sullivan that introduced the Beatles.
