Parse::RecDescent incrementally generates top-down recursive-descent text parsers from simple yacc-like grammar specifications. It provides: * Regular expressions or literal strings as terminals (tokens) * Multiple (non-contiguous) productions for any rule * Repeated and optional subrules within productions * Full access to Perl within actions specified as part of the grammar * Simple automated error reporting during parser generation and parsing * The ability to commit to, uncommit to, or reject particular productions during a parse * The ability to pass data up and down the parse tree ("down" via subrule argument lists, "up" via subrule return values) * Incremental extension of the parsing grammar (even during a parse) * Precompilation of parser objects * User-definable reduce-reduce conflict resolution via "scoring" of matching productions

This package is the shared library for perl.
Extract delimited text sequences from strings
These Perl subroutines may be used to extract a delimited substring, possibly after skipping a specified prefix string.
The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
Stringified perl data structures, suitable for both printing and eval
Given a list of scalars or reference variables, writes out their contents in perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. Handles self-referential structures correctly. The return value can be evaled to get back an identical copy of the original reference structure. (Please do consider the security implications of eval'ing code from untrusted sources!)
