Overview

Compiler module methods

Instance Method Summary

• #compile(mod, grammar_or_parser, opts = {}) ⇒ Object

• #compile_parser(base, grammar_or_parser, opts = {}) ⇒ Object

  Compile grammar source or a parser model into a new parser subclass of base.

Instance Method Details

#compile(mod, grammar, opts) ⇒ Module #compile(mod, parser, opts) ⇒ Module

Compile grammar source or a parser model into match methods in a module.

Overloads:

• #compile(mod, grammar, opts) ⇒ Module

  Returns mod.

  Parameters:

  • mod (Module) —

    the target module for the match methods

  • grammar (String) —

    the grammar source to compile

  Returns:

  • (Module) —

    mod

• #compile(mod, parser, opts) ⇒ Module

  Returns mod.

  Parameters:

  • mod (Module) —

    the target module for the match methods

  • parser (Rattler::Parsers::Grammar, Rattler::Parsers::RuleSet, Rattler::Parsers::Rule) —

    the parser model to compile

  Returns:

  • (Module) —

    mod

# File 'lib/rattler/compiler.rb', line 51

def compile(mod, grammar_or_parser, opts={})
  model = parser_model(grammar_or_parser)
  mod.module_eval ParserGenerator.code_for(model, opts)
  mod
end

#compile(base, grammar, opts) ⇒ Class #compile(base, parser, opts) ⇒ Class

Compile grammar source or a parser model into a new parser subclass of base.

Overloads:

• #compile(base, grammar, opts) ⇒ Class

  Returns a new sublcass of base with compiled match methods.

  Parameters:

  • base (Class) —

    the base class for the new parser class

  • grammar (String) —

    the grammar source to compile

  Returns:

  • (Class) —

    a new sublcass of base with compiled match methods

• #compile(base, parser, opts) ⇒ Class

  Returns a new sublcass of base with compiled match methods.

  Parameters:

  • base (Class) —

    the base class for the new parser class

  • parser (Rattler::Parsers::Grammar, Rattler::Parsers::RuleSet, Rattler::Parsers::Rule) —

    the parser model to compile

  Returns:

  • (Class) —

    a new sublcass of base with compiled match methods
