Ruby Plays Well With Others

Developing applications entirely in Ruby isn't always practical. It may be desirable to utilize existing code written in other languages. Also, implementing some functionality in Ruby may not yield sufficient performance. When these situations arise, Ruby can invoke code written in Java or C.

The easiest way to invoke Java code from Ruby is to use JRuby (http://jruby.codehaus.org/). JRuby is maturing rapidly now that Sun is financing much of its development.

C code can be invoked from Ruby by using wrapper code that is generated using SWIG (http://www.swig.org/) or written manually.

Google Web Toolkit (GWT)

This talk introduces the GWT, an open-source, Java-based framework for creating Ajax web applications."

Implementing Languages with ANTLR 3

ANTLR 3 (http://antlr.org) is a Java-based tool that generates language parsers in a variety of programming languages including Java. This talk will walk through implementation of a domain-specific language (DSL) using ANTLR.

ANTLR differs from most other parser generators in that it supports
unlimited lookahead to select between grammar rule alternatives.

While languages such a Ruby and Groovy can also be used to implement
DSLs, they bring with them the baggage of their own syntax rules.
ANTLR allows you to make the syntax of your DSL be exactly what you want to be.

We'll start with lexer rules to break a character stream into tokens,
write parser rules that build an abstract syntax tree,
and write tree parser rules that walk the AST and
execute the code that was fed to the lexer.

We'll also demonstrate use of ANTLRWorks which is a
free graphical editor and debugger for ANTLR grammars.
It is particularly useful in stepping through the construction of ASTs.

After attending this talk you'll be ready to begin using ANTLR
to implement your own languages.
