YAML stands for YAML Ain't a Markup Language. Enjoy easy to understand syntax even your boss will be able to read and write! This module will let you write your Kohana config and i18n files in YAML.

Clone the repository (or add it as a submodule) to your modules directory:

$ git clone git://github.com/gevans/kohana-yaml.git modules/yaml

Update & initiate submodules (to get the latest Symfony YAML libraries):

$ cd modules/yaml
$ git submodule update --init

Enable the module in your bootstrap.php:

<?php
Kohana::modules(array(
    'yaml' => MODPATH.'yaml', // YAML config & i18n reader
    // ...
));

Optionally, you can compile php-yaml.

You can write your config files in YAML like so:

# This is a comment
some_key: some_value
group:
  # Don't forget the PHP_EOL or PHP will mess you *and* the line breaks up:
  dynamic_key: <?= 'PHP!'.PHP_EOL ?>
  another_key: another_value

Save the files as config/<filename>.yml and Kohana will be able to read them as usual.

I18n is just as easy as the last part was. Just save your .yml files in the i18n/ while the module does that rest. For example:

# i18n/es.yml
"Hola, :name!": "Hello, :name!"
Yo no hablo Español.: I don't speak Spanish.
Wait. What?: Espere. ¿Qué?

After that, using __('Yo no hablo Español.') returns I don't speak Spanish. Having fun yet?

You can read The Official YAML Web Site for more advanced syntax.

You can enjoy better performance and faster YAML parsing by installing the native YAML extension.

On Ubuntu, install some packages to build the extension:

$ sudo apt-get install build-essential php5-dev libyaml-dev

Then, use PECL to install the extension:

$ sudo pecl install channel://pecl.php.net/yaml-1.0.1

You'll need to enable the newly installed extension. On Ubuntu, you can do so by creating a new file called /etc/php5/conf.d/yaml.ini or adding to your php.ini:

; configuration for YAML extension
extension=yaml.so

Save the file, restart your web server, and you should be good to go!

Using Homebrew, you can install the YAML extension from @josegonzalez's homebrew-php repository:

$ brew install https://raw.github.com/josegonzalez/homebrew-php/master/Formula/yaml-php.rb

To finish installing yaml-php:
  * Add the following line to /usr/local/etc/php.ini:
    extension="/usr/local/Cellar/yaml-php/1.0.1/yaml.so"
  * Restart your webserver.
  * Write a PHP page that calls "phpinfo();"
  * Load it in a browser and look for the info on the yaml module.
  * If you see it, you have been successful!
