MoonScript v0.2.3

Today marksMoonScript version 0.2.3, the CoffeeScript inspired languagethat compiles to Lua. It’s been about 3 months since last release. I've got acouple new features, fixes, Lua 5.2 support and a backwards incompatible change.

You canfollow me on twitter for updates or complaints. Also if you'reusing MoonScript I'd love to hear about it:leafot@gmail.com.

Changes

• For loops when used as expressions will no longer discard nil values whenaccumulating into an array table.This is a backwards incompatiblechange. Instead you should use thecontinue keyword to filter outiterations you don’t want to keep.Read more here.
• Themoonscript module no longer sets a global value formoonscript andinstead returns it. You should update your code:

moonscript=require"moonscript"

New Things

• Lua 5.2 Support. The compiler can now run in either Lua 5.2 and 5.1
• A switchwhen clausecan take multiple values, comma separated.
• Addeddestructuring assignment.
• Addedlocal * (andlocal ^) forhoisting variable declarations in the current scope
• List comprehensions and line decorators now support numeric loop syntax

Bug Fixes

• Numbers that start with a dot, like.03, are correctly parsed
• Fixed typo infold library function
• Fix declaration hoisting inside of class body, works the same aslocal * now

Other Stuff

MoonScript hasmade its way intoGitHub..moon files shouldstart to be recognized in the near future.

Web

I've started a couple interesting projects for MoonScript as a web programminglanguage.

• Lapis — A MoonScript friendly webframework. Includes application routing, a HTML construction MoonScript DSL,and a basic ORM.
• cloud_storage — A MoonScript/Luamodule for interacting with Google Cloud Storage.

Using the following I've created a community powered Lua rock hosting websitecalled MoonRocks:

http://rocks.moonscript.org. (source)

Compiled MoonScript runs inside of the nginx distributionOpenResty. I created a created aLua rock for runningOpenResty on Heroku in conjunctionwith myHeroku Lua buildpack.

Games

Ludum Dare happened again, two games were created inMoonScript:

• X-Moon
• Event Horizon — by SelectricSimian

Additionally, Michael F has created a game engine, BoxEngine, whichnatively supports MoonScript.
