pkg extends the standard "use" statement to more transparently handle inner packages, additionally incorporating some of the functionality of the aliased and use pragmata with a few extra twists. An inner package is one which does not have the same n...

In scientific (and other) applications, it is frequently necessary to classify a series of values in a number of bins. For instance, particles may be classified according to particle size in a number of bins of, say, 0.01 mm wide, yielding a histogra...

Platypus is a library for creating interfaces to machine code libraries written in languages like C, C++, Go, Fortran, Rust, Pascal. Essentially anything that gets compiled into machine code. This implementation uses "libffi" to accomplish this task....

Lua is a simple, expressive, extension programming language that is easily embeddable. Lua::API provides Perl bindings to Lua's C-based embedding API. It allows Perl routines to be called from Lua as if they were written in C, and allows Perl routine...

This module provides tools for building external (non-CPAN) dependencies for CPAN. It is mainly designed to be used at install time of a CPAN client, and work closely with Alien::Base which is used at runtime. This is the detailed documentation for t...

Beam::Wire is a configuration module and a dependency injection container. In addition to complex data structures, Beam::Wire configures and creates plain old Perl objects. A dependency injection (DI) container creates an inversion of control: Instea...

This module allows you to compose Test::More tests from roles. It is inspired by the excellent Test::Routine module, but uses Moo instead of Moose. This gives most of the benefits without the need for Moose as a test dependency. Test files are Moo cl...

App::Env presents a uniform interface to initializing environments for applications which require special environments. App::Env only handles the loading, merging, and caching of environments; it does not create them. That is done within modules for ...

• App::Env::Null - return a snapshot of the current environment

App::Cmd is intended to make it easy to write complex command-line applications without having to think about most of the annoying things usually involved. For information on how to start using App::Cmd, see App::Cmd::Tutorial....

This class provides access to the XPA messaging system library, "xpa", developed by the Smithsonian Astrophysical Observatory's High Energy Astrophysics R&D Group. The library provides simple inter-process communication via calls to the "xpa" library...

This module provides multi-dimensional implementations of common functions....

This class provides access to the DS9 image display and analysis program through its XPA access points. DS9 is a rather flexible and feature-rich image display program. Rather than extol its virtues, please consult the website in "REQUIREMENTS". Whil...

This module provides an inteface to the PGPLOT graphics library. To obtain the library and its manual, see "OBTAINING PGPLOT". For every PGPLOT function the module provides an equivalent Perl function with the same arguments. Thus the user of the mod...

Typically PDL uses bad values to mark elements in a piddle which contain invalid data. When multiple piddles should have the same elements marked as invalid, a separate *mask* piddle (whose values are true for valid data and false otherwise) is often...

• PDLx::Role::RestrictedPDL - restrict write access to a PDL object as much as possible

Pg::Simple is a very simple interface to PostgreSQL. It is patterned after the DBI interface. Why not use the DBI interface instead? The main reason is that it does not yet support cursors. This module does. When the DBI Postgres interface supports c...

This module provides a simple, light and minimalistic way of validating user input. Except perl core modules and some test modules it has no other dependencies, which is why it does not implement any complicated checks and filters such as email and c...

This module reads *key - value* data pairs from a file. What sets it apart from other configuration systems is that keys may contain Perl regular expressions, allowing one entry to match multiple requested keys. Configuration information in the file ...

This role is used by classes that want to add callback hooks to allow users to add new behaviors to their objects. These hooks are called "events". A subscriber registers a callback for an event using the "subscribe" or "on" methods. Then, the class ...

This module iterates over files and directories to identify ones matching a user-defined set of rules. The API is based heavily on File::Find::Rule, but with more explicit distinction between matching rules and options that influence how directories ...
