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
