One Factory To Rule Them All
Have a script that needs to utilize several VersionControl_SVN
subclasses? At the expense of a little overhead, you can be sure
your $svn objects are fully-loaded by using the
VersionControl_SVN::factory() command keyword
__ALL__.
For example, in a basic script to get the list of current files in a repository, you just need the VersionControl_SVN::VersionControl_SVN_List() subclass.
Getting the list of current files in a repository
<?php
require_once 'VersionControl/SVN.php';
// Setup error handling -- always a good idea!
$svnstack = &PEAR_ErrorStack::singleton('VersionControl_SVN');
// Set up runtime options.
$options = array('fetchmode' => VERSIONCONTROL_SVN_FETCHMODE_ARRAY);
// Request list class from factory
$svn = VersionControl_SVN::factory('list', $options);
// Define any switches and aguments we may need
$switches = array('username' => 'user', 'password' => 'pass');
$args = array('svn://svn.example.com/repos/TestProject');
// Run command
if ($output = $svn->run($args, $switches)) {
print_r($output);
} else {
if (count($errs = $svnstack->getErrors())) {
foreach ($errs as $err) {
echo '<br />'.$err['message']."<br />\n";
echo "Command used: " . $err['params']['cmd'];
}
}
}
?>
However, if you need to get a recursive list of files in a repository, look up the recent log activity for those files, and view the annotated source for those files, you've got two options.
Recursively getting the list of current files in a repository
<?php
require_once 'VersionControl/SVN.php';
// Setup error handling -- always a good idea!
$svnstack = &PEAR_ErrorStack::singleton('VersionControl_SVN');
// Set up runtime options.
$options = array('fetchmode' => VERSIONCONTROL_SVN_FETCHMODE_RAW);
// METHOD ONE: Lowest Overhead
// Create svn object with subcommands we need listed out individually
$svn = VersionControl_SVN::factory(array('list', 'log', 'blame'), $options);
// Define any switches and aguments we may need
$switches = array('username' => 'user', 'password' => 'pass');
$args = array('svn://svn.example.com/repos/TestProject');
print_r($svn->list->run($args, $switches));
// Pick files out of the above output, and see who did what
$args = array('svn://svn.example.com/repos/TestProject/trunk/index.php');
echo "<pre>" . $svn->blame->run($args) . "</pre>";
// METHOD TWO: Put all available commands at your disposal
// Load up all subcommands - higher overhead, but convenient for certain occasions
$svn = VersionControl_SVN::factory('__ALL__', $options);
// Now you may run whatever you need to ...
$svn->cat->run($args, $switches);
$svn->info->run($args, $switches);
// ... and so on.
