FileGen

Build Status SensioLabsInsight Scrutinizer Code Quality

A small tool to aid in the creation of (complicated) file and directory

layouts.

use Naneau\FileGen\Structure;
use Naneau\FileGen\Generator;

// Specify a structure to be generated
$structure = new Structure;
$structure
    ->directory('foo')
    ->file('bar/baz', 'these are the file contents');
    ->link('/some/file/somewhere', 'qux');

// Generate the structure
$generator = new Generator('/output/directory');
$generator->generate($structure);

will output:

- /output/directory/
    - foo/
    - bar/
        - baz
    - qux => /some/file/somewhere

Examples

Copy A File

Copying an existing file to a new file in the structure to be generated is easy.

use Naneau\FileGen\Structure;
use Naneau\FileGen\File\Contents\Copy;

$structure = new Structure;
$structure->file('foo', new Copy('/from/this/file'));

Use a Twig Template

Files can be given content using a Twig template.

use Naneau\FileGen\Structure;
use Naneau\FileGen\File\Contents\Twig;

// $twig = ...

// Load a template
$template = $twig->load('some_template.twig');

// Parameters for the template
$parameters = array('foo' => 'bar')

$structure = new Structure;
$structure->file('foo', new Twig($template, $parameters));

Set up A Parameter Specification Alongside A Structure

In some cases you'll want to specify parameters to be used by your structure beforehand. These parameters can then be queried for using the console helper (see below), and used in Twig templates.

use Naneau\FileGen\Generator;
use Naneau\FileGen\Structure;
use Naneau\FileGen\File\Contents\Twig;

// $twig = ...
$template = ;
$structure = new Structure;
$structure
    // A parameter "foo" is expected
    ->param('foo')

    // A bar parameter with a description
    ->param('bar', 'Please specify "bar"')

    // Can use {{ foo }} and {{ bar }}
    ->file('someFile', new Twig($twig->load('someFile.twig'));

    // Can also use {{ foo }} and {{ bar }}
    ->file('anotherFile', new Twig($twig->load('anotherFile.twig'));

// Set a default value for foo
$structure->getParameterDefinition()->get('foo')->setDefaultValue('Foo!');

// Pass values for the structure's parameters to the generator
$generator = new Generator('/output/directory', array(
    'foo' => 'foo!'
    'bar' => 12345
));

// Generate the structure
$generator->generate($structure);

Console Helper

FileGen ships with a a (Symfony Console Helper](http://symfony.com/doc/current/components/console/introduction.html#console-helpers) that will use the built-in question helper to ask for parameter values.

Simply add the helper to your console helper set:

use Naneau\FileGen\Console\Helper\ParameterHelper;

// $application = ...
$application->getHelperSet()->set(new ParameterHelper, 'filegenParameters');

And use it in your commands:

protected function execute(InputInterface $input, OutputInterface $output)
{
    // $structure = ...

    $helper = $this->getHelper('filegenParameters');

    // Ask for all parameters one by one
    $parameters = $helper->askParameters($structure, $input, $output);

    // Ask for a single parameter
    $fooParameter = $structure->getParameterDefinition()->get('foo');
    $fooValue = $helper->askParameter($fooParameter, $input, $output);
}
