    NAME

    yapp - A perl frontend to the Parse::Yapp module
     
    

    SYNOPSYS

    yapp [options] grammar[.yp]

    yapp -V

    yapp -h  

    DESCRIPTION

    yapp is a frontend to the Parse::Yapp module, which lets you compile Parse::Yapp grammar input files into Perl LALR(1) OO parser modules.  

    OPTIONS

    Options, as of today, are all optionals :-)
    -v
    Creates a file grammar.output describing your parser. It will show you a summary of conflicts, rules, the DFA (Deterministic Finite Automaton) states and overall usage of the parser.
    -s
    Create a standalone module in which the driver is included. Note that if you have more than one parser module called from a program, to have it standalone, you need this option only for one of your parser module.
    -n
    Disable source file line numbering embedded in your parser module. I don't know why one should need it, but it's there.
    -m module
    Gives your parser module the package name (or name space or module name or class name or whatever-you-call-it) of module. It defaults to grammar
    -o outfile
    The compiled output file will be named outfile for your parser module. It defaults to grammar.pm or, if you specified the option -m A::Module::Name (see below), to Name.pm.
    -t filename
    The -t filename option allows you to specify a file which should be used as template for generating the parser output. The default is to use the internal template defined in Parse::Yapp::Output.pm. For how to write your own template and which substitutions are available, have a look to the module Parse::Yapp::Output.pm : it should be obvious.
    -b shebang
    If you work on systems that understand so called shebangs, and your generated parser is directly an executable script, you can specifie one with the -b option, ie:

        yapp -b '/usr/local/bin/perl -w' -o myscript.pl myscript.yp
    
    
    
    This will output a file called myscript.pl whose very first line is:

        #!/usr/local/bin/perl -w
    
    
    
    The argument is mandatory, but if you specify an empty string, the value of $Config{perlpath} will be used instead.
    grammar
    The input grammar file. If no suffix is given, and the file does not exists, an attempt to open the file with a suffix of .yp is tried before exiting.
    -V
    Display current version of Parse::Yapp and gracefully exits.
    -h
    Display the usage screen.
