Lua2JS

LiveDemo: http://basicer.com/lua2js/

NPM Package: https://www.npmjs.org/package/lua2js

Repository: http://github.com/basicer/lua2js/

Some features I think make my parser special

• Runs many lua programs off the shelf with identical output to stock interpreter
• Operators replaced with function calls to maintain correct lua behavior.
• Lots of blood, sweat and tears to support language features like tuple unpacking and ... arguments.
• Tunable parser options to enable and disable different AST transforms to support trade-offs between correct lua behavior and cleaner javascript output.
• Many features (loops, calls, operators) detect javascript vs lua objects and at accordingly. (Fix the value of this, round trip lua tables as arrays when passed to JS functions, etc..)
• Custom error messages for common mistakes, such as forgetting an end, not closing "'s etc.
• Above error messages mention the beginning of the block they are referring to.
• Parser grammar written from scratch using PEG.js instead of porting existing JS parser.
• Loose parsing mode with support for multiple error messages and running half working programs.
• No runtime NPM dependencies, all runtime code MIT (or some other license if you prefer!)
