To use generated code, you'll need to include ActionScript runtime package antlr3.swc in your library path. There are no other dependencies beyond the standard Flex libraries. Note, that the library contains some Adobe AIR class references, to use the library in a pure Flex project use the -library-path compiler option rather than the {{-include-library} option when compiling from the command line.

Usage

Selecting ActionScript output

...

For a grammar T.g ANTLR3 will then create the files TLexer.as and TParser.as which contain the classes TLexer and TParser (or just one of those, if you have a pure lexer/parser). For tree parsers, ANTLR3 creates T.as containing the class T.

Specifying an ActionScript package for your recognizer

You can specify that your generated recognizer should be declared within a specific package as shown below. By default all recognizers are generated as top-level types with no enclosing package.

grammar MyGrammar;

options
{
    language=ActionScript;
}

@parser::package { My.Custom.NameSpace.For.Parser.In.Combined.Grammar } // Or just @package { ... }

@lexer::package { My.Custom.NameSpace.For.Lexer.In.Combined.Grammar }

// rest of grammar follows
....

lexer grammar MyGrammar;

options
{
    language=ActionScript;
}

@package { My.Custom.NameSpace.For.Lexer }

// rest of grammar follows
....

parser grammar MyGrammar;

options
{
    language=ActionScript;
}

@package { My.Custom.NameSpace.For.Parser }

// rest of grammar follows
....

tree grammar MyGrammar;

options
{
    language=ActionScript;
}

@package { My.Custom.NameSpace.For.TreeParser }

// rest of grammar follows
....
