ANN: Hy - Python / Lisp interoperability layer (0.9.6)

[Paul Tagliamonte]

Hello, World!

tl;dr
=====

Version:   0.9.6
License:   Expat (sometimes called MIT)
Hilarious: Yes
Site:      http://hylang.org 

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)


What's new
==========

There's a new release of hy (version 0.9.6) pushed to PyPi. It's hand-crafted
with the utmost care from the AUTHORS[1] to help you (yes, you!) hack using
Lisp without giving up your Python libs of choice (or even your Python
libs giving up on you!)

The source is on GitHub @ http://github.com/hylang/hy (star it,
fork it, hack it)

It's undergoing changes quite quickly - so, be careful! The API / language
is being worked out very quickly.

The two releases since the last post here (0.9.5 and 0.9.6) features the
following select features (for a full list, check NEWS, this is seriously
cut down)


    * Added all the missing math operators.
    * We now support float and complex numbers.
    * Keywords (such as :foo) are now valid and loved.
    * `try' now accepts `else'
    * Added "not" as the inline "not" operator.
    * `let' macro added
    * Added "~" as the "invert" operator.
    * Added the tail threading macro (->>)
    * UTF encoded symbols are allowed, but mangled.
    * If hoisting (for things like printing the return of an if statement)
      have been added. '(print (if true true true))'


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

Thanks!

Thanks, folks! Tweet about it, hack with it, hang out with us on #hy

Fondly, and with just tons of love,
