Hy

Exploring hy lang

• This seems like a fun way to explore programming models.

• The docs are nice, but a little bit rough, I may be able to help there.

• Potential projects:

  • PAIP in Hy
  • This year's advent of code
  • Nanogpt, Llama2 in Hy + JAX

• Getting started

  • pip install hy hyrule
  • jedhy is a bit outdated / broken
  • the emacs mode for jedhy is also broken as a consequence; disabling company-mode helps

Cheatsheet

For things I find myself looking up repeatedly

• (require module :reader [macroname]) for reader macros
• slicing / slice macros are a little bit kludgy
• #() tuples aren't hashable?
• a.b.c etc. sugar just works, don't need to use (. a b) forms

Ecosystem improvements

• Better highlighting, specially in tuples #()
• Easy to use repl with syntax highlighting
• Inferior emacs mode that just works
• Live reload mode / live eval mode?
• Stack traces should be more readable
• Close enough to python to make me itch
• A potential bug? in function handling when using a.b.c[x]; not sure if supported
• Quick way to check generated python code for a given code snippet
