This module provides methods to compact javascript source down to just what is needed. It can remove all comments, put everything on one line (semi-)safely, and remove extra whitespace.

Marpa::PP is the pure Perl version of Marpa. Marpa parses any language whose grammar can be written in BNF. That includes recursive grammars, ambiguous grammars, infinitely ambiguous grammars and grammars with useless or empty productions.

Marpa::XS is the XS version of Marpa. Marpa parses any language whose grammar can be written in BNF. That includes recursive grammars, ambiguous grammars, infinitely ambiguous grammars and grammars with useless or empty productions.

Modern Perl programs use several modules to enable additional features of Perl and of the CPAN.

This module provides the capability to parse a string at runtime as Perl source code, so that the resulting compiled code can be later executed. This is part of the job of the string form of the eval operator, but in this module it is separated out from the other jobs of eval. Parsing of Perl code is generally influenced by its lexical context, and this module provides some explicit control over this process, by reifying lexical environments as Perl objects.

Perl6::Subs is a source filter that adds a very useful subset of Perl 6 subroutine syntax to Perl 5. Given a subroutine defined with a Perl 6 prototype, the code generated by Perl6::Subs will, at runtime, declare the formal parameters, assign them their values, and validate their contents according to both built-in and user-given rules.

This module is an implementation of the "Promise/A+" pattern for asynchronous programming. Promises are meant to be a way to better deal with the resulting callback spaghetti that can often result in asynchronous programs.

This module provides an implementation for Perl 6 Rules. It is a front-end to several other modules: * Pugs::Grammar::Rule parses the Rules syntax. * Pugs::Grammar::Rule::Rule specifies the Rules syntax with Rules. * Pugs::Emitter::Rule::Perl5 converts parsed Rules to Perl 5 code. * Pugs::Runtime::Rule provides the runtime engine for Rules. * Pugs::Runtime::Match represents a Match object.

The Quantum::Superpositions module adds two new operators to Perl: any and all. Each of these operators takes a list of values (states) and superimposes them into a single scalar value (a superposition), which can then be stored in a standard scalar variable. The any and all operators produce two distinct kinds of superposition. The any operator produces a disjunctive superposition, which may (notionally) be in any one of its states at any time, according to the needs of the algorithm that uses it. In contrast, the all operator creates a conjunctive superposition, which is always in every one of its states simultaneously. Superpositions are scalar values and hence can participate in arithmetic and logical operations just like any other type of scalar. However, when an operation is applied to a superposition, it is applied (notionally) in parallel to each of the states in that superposition.
