Packager

Packager is a PHP 5.2+ library to concatenate libraries split in multiple files in a single file. It automatically calculates dependancies. Packager requires a yml header syntax in every file, and a package.yml manifest file, as seen on the MooTools project.

Packager API

Constructor

The constructor of this class accepts either a path to a package or a list of path to packages. package.yml must not be included in the path.

Example

$pkg = new Packager("/Users/kamicane/Sites/mootools-core/");
$pkg = new Packager(array("/Users/kamicane/Sites/mootools-core/", "/Users/kamicane/Sites/mootools-more/"));

Adding a manifest

• parse_manifest » adds a manifest to this instance

Working with files

Getters

• get_all_files » gets an list of all files
• get_file_dependancies » gets an ordered list of every file that this file depends on
• get_file_path » gets the file path
• get_file_source » gets the file source
• get_file_description » gets the file description
• get_file_provides » gets a list of the file provided components

Converters

• complete_file » converts a single file to an ordered list of files
• complete_files » converts a list of files to an ordered list of files

Generators

• build_from_files » returns a string containing the source of the selected files and their dependancies
• write_from_files » writes a file with the selected files and their dependancies

Working with components

Converting to files

• component_to_file » gets the name of the file that provides this component
• components_to_files » converts a list of components to a list of files

Generators

• build_from_components » returns a string containing the source of the selected components and their dependancies
• write_from_components » writes a file with the selected components and their dependancies

Class usage

Syntax

$pkg = new Packager(`$path_to_manifest`);

Example

$pkg = new Packager("/Users/kamicane/Sites/mootools-core/");

$pkg->write_from_components("/Users/kamicane/Sites/mootools.js", array('Type', 'Array'));

Packager Command Line script

The Packager command line script is your one-stop solution to build any of your packages at once. Works on unices.

Syntax

./packager COMMAND +option1 argument1 argument2 +option2 argument1 argument2

• COMMAND a packager command (required)
• +option options for commands (optional)

Commands

• register registers a package. Creates a .packages.yml file in your home folder.
• unregister unregisters a package
• list list registered packages
• build builds a single file with the supplied packages / files / components

Registering a Package

Example

./packager register /Users/kamicane/mootools-core
» the package Core has been registered

Listing Packages

Example

./packager list
» Core: /Users/kamicane/mootools-core

Unregistering a Package

Example

./packager unregister Core
» the package Core has been unregistered

Building Packages

Examples

./packager build Core/Type Core/Fx ART/ART.Element

Which is the same as...

./packager build +components Core/Type Core/Fx ART/ART.Element

Which builds the passed in components (and their dependancies) using your registered packages.

./packager build +components Core/Type Core/Fx ART/ART.Element -components Core/Core

This will build a library that has the same dependencies as the previous example but exclude the Core/Core component.

./packager build +files Core/Core Core/Fx ART/ART

This builds the passed in files (and their dependancies) using your registered packages.

./packager build ART/*

Builds every component from ART, and their dependancies, using your registered packages.

./packager build SomePackage/SomeComponent +packages /Users/kamicane/Sites/some-package

Builds the selected components using your registered packages and a temporary package that resides in /Users/kamicane/Sites/some-package, without having to register it first.

./packager build SomePackage/SomeComponent -packages Core

Builds the selected components using your registered packages minus the package names you pass to -packages. This lets you build your components without dependancies.

./packager build ART/SomeComponent +use-only ART

Builds the selected components using only ART of your registered packages. This lets you build your components without dependancies.

./packager build SomePackage/SomeComponent +use-only +packages /Users/kamicane/Sites/some-package

Builds the selected components using none of your registered packages plus the passed in package, without registering it. This lets you build your components without dependancies.

./packager build +components ART/ART +files ART/ART.Base

You can mix components and files

./packager build Core/* > mootools.js

This is how you output to a file
