NAME

Erlang::Parser - Erlang source code parser

VERSION

This document describes version 0.4 of Erlang::Parser released 2011-11-07.

SYNOPSIS

    use Erlang::Parser;

    # Parse the code found in DATA; return all root-level nodes.
    my @nodes = Erlang::Parser->parse(\*DATA);

    # Each object in @nodes implements the Erlang::Parser::Node role, which
    # is the function 'print'. It takes one argument, the filehandle to
    # pretty-print to.
    $_->print(*STDOUT) for @nodes;

    # Use the accessors of each node type to get at the innards:
    my ($directive, $def) = Erlang::Parser->parse(<<ERL);
        -export([my_fun/2]).
        my_fun(X, Y) -> X + Y.
