README

Ken is a project automation tool in Hacklang and can be used as a general build tool as well.

Ken exists because of Bob, a great PHP tool it's based on. I haven't forked because the project changed too much.

How it works

Ken doesn't use XML/JSON for task files. Instead, tasks are registered with the PHP language itself using the TaskLibraryInterface or configuration files.

Application is the core object used by developers to register task files or libraries.

The tasks are created by TaskFactory.

Getting Started

If not specified, the default configuration file is loaded from ken_config.php

If the folder ken_tasks exists, then all files inside it are threated as configuration files.

A configuration file is required at runtime and uses 2 functions:

• task(name, dependencies, action) - register a new task ..+ task(name, dependencies) ..+task(name, action) ..+task(action)
• desc(text) - provides the description for the next task defined

The configuration file has also a global instance of Application that can be accesed outside the task closure, internally know as action.

desc('Concat clientside code');
task('concat', function(Application $app) {
	// concat files
});

desc('Minify clientside code');
task('minify', function(Application $app) {
	// minify files
});

task('default', ['concat', 'minify'])

To provide a better OOO approach, you can define tasks instead with TaskLibraryInterface.

Libraries are registered in Application with:

register(TaskLibraryInterface $taskLib, array $parameters = array())

To create a new library you must implement the TaskLibraryInterface. For an example, check the ComposerLibrary which manage composer packages.

Client Interfaces

The ClientInterface represents the entry point for developers to use the Ken library.

For now there're two implementations for ClientInterface:

• Cli: The CLI implementation to be used with HHVM client
• Host: An implementation to be used inside another framework or existing project (you're able to execute tasks from inside your code easily)

While the CLI is used to execute tasks directly from the command line, the Host is used to be consumed inside other code.

Both Cli and Host initialize the client dependencies creating a new Application then the method run is invoked.

Cli

The CLI is pretty straightford and you can access it through bin/ken.

When called the run method, the Cli executes the tasks.

Host

The Host client must be run at Application Startup, before any consumption to Ken is done. To execute the tasks, the developer invokes the task method.

Install

Pre Requesites

Ken needs at least hhvm 3.8 to run.

Composer

Add the guilhermegeek/ken package to the require-dev section in your composer

{
	"require-dev": {
		"guilhermegeek/ken": "master"
	}
}

Then run composer install -dev

You can invoke ken with:

hhvm bin/ken
