NAME

       tt - Compile a treetop grammar file to ruby source code

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
