task/filesystem

Example

use Task\Plugin\FilesystemPlugin;
use Symfony\Component\Finder\Finder;

$project->inject(function ($container) {
    $container['fs'] = new FilesystemPlugin;
});

$project->addTask('write', ['fs', function ($fs) {
    $fs->open('/tmp/foo')->write('wow');
}]);

$project->addTask('read', ['fs', function ($fs) {
    $fs->read('/tmp/foo')->pipe($this->getOutput());
}]);

$project->addTask('copy', ['fs', function ($fs) {
    $fs->copy('/tmp/foo', '/tmp/bar');
    # OR
    $fs->read('/tmp/foo')->pipe($fs->touch('/tmp/bar'));
}]);

$project->addTask('copyTree', ['fs', function ($fs) {
    $finder = new Finder;
    $finder->name('foo')->in('/tmp/source');
    $fs->copyTree('/tmp'source', '/tmp/target', $finder);
}]);

Installation

Add to composer.json:

    "task/filesystem": "~0.2"
}

Usage

Task\Plugin\FilesystemPlugin extends Symfony's Filesystem component object, overring some methods and providing some new ones. Many of these methods return streams which can be piped to other plugins. open

open($filename, $mode = 'r+')

Returns Task\Plugin\Filesystem\File, opened with the specified mode. touch

FilesystemPlugin::touch($filename, $time = null, $atime = null)

See Symfony's Filesystem::touch documentation for argument description. Returns Task\Plugin\Filesystem\File, opened with r+. ls

ls($dir)

Returns Task\Plugin\Filesystem\FilesystemIterator. copy

copy($source, $target, $override = false)

Supports multiple operations, e.g.

Given:

use Task\Plugin\FilesystemPlugin;
$fs = new FilesystemPlugin;

File to file:

/
    foo

# @return File('bar')
$fs->copy('foo', 'bar')

/
    foo
    bar

File to directory:

/
    foo
    bar/

# @return File('bar/foo')
$fs->copy('foo', 'bar')

/
    foo
    bar/
        foo

Link to link:

/
    foo
    bar -> foo

# @return File('wow')
$fs->copy('foo', 'wow')

/
    foo
    bar -> foo
    wow -> foo

Directory to directory:

/
    foo/
        bar

# @return FilesystemIterator('wow')
$fs->copy('foo', 'wow')

/
    foo/
        bar
    wow/
        bar

mirror

mirror($originDir, $targetDir, Traversable $iterator = null, $options = []) Mirror a directory, optionally providing a Traversable instance to select or exclude files. Symfony's Finder component is really good for this:

/
    foo/
        .git/
            objects/
        bar
        baz

use Task\Plugin\FilesystemPlugin;
use Symfony\Component\Finder\Finder;

$finder = new Finder;
$finder->ignoreVcs()->in('foo');

$fs = new FilesystemPlugin;
# @return FilesystemIterator('wow')
$fs->mirror('foo', 'wow', $finder);

/
    foo/
        .git/
            objects/
        bar
        baz
    wow/
        bar
        baz
