Onion

Onion, The fast approach to make/install/bundle PEAR packages for PHP.

Onion is able to generate a PEAR2-compatible package.xml file from a very simple config file, you can release your PEAR package very quickly!

And through Onion, you can also install PEAR dependencies into local bundle (just like Ruby Bundler).

Onion is not target to replace other package manager, its target is to make current PEAR ecosystem easier.

Let's keep hard long PEAR package.xml away! :-)

Onion is for people want to..

• Build PEAR, PECL package easily, quickly.
• Install PEAR dependencies into local project directory. (like Ruby Bundler)

What People Say

nrk:

its own package.ini file looks simple enough to edit and maintain.

It's been super-easy to get up and running and I haven't encountered any real
problems.  Onion looks good already.

Requirement

• PHP 5.3
• simplexml extension
• DOMDocument extension
• curl

The minimal spec file

[package]
name = Onion
desc = package description
version = 0.0.1
author = Yo-An Lin <cornelius.howl@gmail.com>
channel = pear.php.net

A Quick tutorial for building PEAR package

Get and install onion:

$ curl -s http://install.onionphp.org/ | sh

Please make sure your directory structure:

src/   # contains php source code
doc/   # documentation files (optional)
tests/ # unit testing files

Fill your package.ini file:

[package]
name = Onion
desc = package description
version = 0.0.1
channel = pear.php.net
author = Yo-An Lin <cornelius.howl@gmail.com>

To generate a package.xml 2.0 spec file for PEAR and build a PEAR package, just run:

$ onion build --pear

Then Your PEAR package is out!

The --pear flag is optional.

See:

$ onion help build

Adding package dependencies

[package]
name = Onion
desc = package description
version = 0.0.1
author = Yo-An Lin <cornelius.howl@gmail.com>
channel = pear.php.net

[require]
php = 5.3
pearinstaller = 1.4
pear.php.net/PackageName = 0.0.1

Bundle

Install PEAR dependencies into vendor/ directory

$ onion install

Compile package to Phar executable/library file

An example, we use onion to compile our executable file onion:

$ onion compile \
    --executable \
    --classloader \
    --bootstrap scripts/onion.embed \
    --lib src \
    --lib ../CLIFramework/src \
    --lib ../GetOptionKit/src \
    --output onion

For C Extensions

Simple put a extension attribute:

[package]
...
extension = yourext

Available Config Tags

please checkout doc/SPEC.md

Version Naming

version naming standard from PEAR group: http://pear.php.net/manual/en/rfc.version-naming.standard.php

Customize roles

There are many built-in roles so that you don't need to define it by yourself, built-in roles are:

• src/ php role
• docs/ doc role
• tests/ test role
• *.md doc role

But you can add custom roles by yourself.

[roles]
path/to/data = data
path/to/library = php
path/to/doc = doc

A more detailed example

[package]
name        = your package name
desc        = package description
summary     = ....                  # optional, default to Description
homepage    = http://your.web.com   # optional

channel     = pear.php.net          # default

; lead developer
author         = Yo-An Lin <cornelius.howl@gmail.com>

; other authors
authors[]      = Yo-An Lin <cornelius.howl@gmail.com>
authors[]      = Yo-An Lin

 ; contributors ...
contributors[] = ...                # optional
maintainers[]  = ...                # optional

[require]

; pear package based on channel
pear.channel.net/package = 1.1

; pear package based on URI
package = http://www.example.com/Foo-1.3.0
package = conflicts

extension/reflection = 
extension/ctype = 
extension/pcre =
