Hello, World! tl;dr ===== Version: 0.9.4 License: Expat (sometimes called MIT) Hilarious: Yes Hy is a wicked funny hack that lets you interop (in both directions) with Lisp from Python (or with Python from Lisp). It's pip installable: $ pip install hy [...] $ hy => (print (.join ", " ["Hello" "World"])) Hello, World (REPL even has cute readline bits mostly workingish, with a few known issues) And the source is on GitHub @ http://git.io/hy (star it, fork it, hack it) It's undergoing changes quite quickly - so, be careful! OK, what is it (technically) ============================ Hy is a set of hacks, implemented in Python, to lex and compile a Lisp variant (called `Hy', which looks very similar to Clojure in some ways) into Python AST, and transparently load it into sys.modules using a PEP 302 import hook. I gave a lightning talk about Hy at PyCon, in case anyone's having flashbacks. You can see that talk on my blog (http://blog.pault.ag/post/46982895940/), or watch a full hour-long talk about Hy at Boston Python at http://www.youtube.com/watch?v=ulekCWvDFVI Right, so that means? ===================== You can do hilarious (hylarious?) things like write full Django projects[1] in Lisp, or interop with pymongo[2], or even use pdb to debug Lisp code[3]. Wait, are you serious? ====================== About it working? Yup! About making this lisp-variant production quality? Not really. It's just really funny, and helps teach people about how awesome Python is. Whatabout Macros? ================= Yep!(*) *: but you have to write them in Python for now (code plot'ed) :( Docs? ===== Yep! http://hy.rtfd.org/ - could use help! Hacks welcome!
