Hi!
I’m wondering if Treetop can provide (or is it already have?) a
mechanize like this:
module MyModule
Treetop.load(“my”)
end
so that I’ll get a MyModule::MyParser instead of a top-level MyParser.
Or something like:
Treetop.load_into(“my”, MyModule)
which might be implemented like the original `load’:
def self.load(path)
def self.load_into(path, module)
adjusted_path = path =~ /.(treetop|tt)\Z/ ? path : path +
‘.treetop’
compiler = Treetop::Compiler::GrammarCompiler.new
Object.class_eval(compiler.ruby_source(adjusted_path))
module.class_eval(compiler.ruby_source(adjusted_path))
end
Any idea? Thanks!

You can use tt to generate the parsing module:
tt my.treetop
Then to get it into your MyModule:
require ‘my’
module MyModule
include My
end

The Treetop meta-grammar allows you to define your grammar inside a
module, even more than one level. The parser will be emitted inside
a module of the same name.
module MyModule
grammar MyLang
rule top
…
end
end

Yes! That’s exactly what I’m looking for! Thanks!
