SYNOPSIS

tt [options] grammar_file[.treetop|.tt] ...

DESCRIPTION

The tt program is a command-line script to compile .treetop files into Ruby source code.

The tt program takes a list of files with a .treetop extension and compiles them into .rb files of the same name. You can then require these files like any other Ruby script.

Alternately, you can supply just one .treetop file and a -o flag to specify the name of the output file.

Note: while treetop grammar files must have a supported filename extensions, (.treetop or .tt), the extension name is not required when calling the compiler with grammar file names.

OPTIONS

-o, --output FILENAME

Write parser source to FILENAME.

-f, --force

Overwrite existing output file(s)

-v, --version

Show Treetop version

-h, --help

EXAMPLES

1 grammar -> 1 parser source

tt foo.tt

2 grammars -> 2 separate parsers

tt foo bar.treetop

Alternately named output file

tt -o alterate_name.rb foo
