README

Fuko\Open is a small PHP library that helps you to generate links for opening referenced files directly in your IDE or editor, or have it linked to an online repository.

Basic Use

At the heart of it is all is the \Fuko\Open\Link class, which is really simple: it takes a format to use in its constructor, and then using that format it creates a formatted link to a code reference identified by its file and line:

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\Link;

$link = new Link('source-code://%s:%d');
$href = $link->link(__FILE__, __LINE__);

The format is sprintf()-based, with two placeholders: first one is %s for the file, and the second one is %d for the line. That's it, it's pretty simple.

Translating Paths

There are occasions when leading portions of the filenames must be "translated" to something different, like when:

• like when you get the real path to a file after some of its parent folders was a symlink that was resolved to its real source;

• like when you've mounted a shared network volume with your web server machine, and you want to use the locally mounted names, and not the remote ones

• or like when you are using Docker and you want to translate the Docker-based filenames to your locally-accessible filenames.

For all of those cases, the \Fuko\Open\Link objects have the ability to replace leading filename prefixes. You can add a new prefix for translating a file path like this:

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\Link;

$link = new Link('source-code://%s#%05d');
$link->addPrefix(getcwd() . '/', '/upside/down/');
$href = $link->link(__FILE__, __LINE__);
// source-code://%2Fupside%2Fdown%2Fdemo.php#00023

You can add multiple prefixes, as usually there is more than one symlinked folder in most projects.

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\{Link, Editor};

$href = (new Link(Editor::ATOM))
	->addPrefix(getcwd() . '/', '/upside/down/')
	->addPrefix('/private/tmp', 'tmp')
	->link(__FILE__, __LINE__);

Editor Links

There are several IDEs and editors that support special URL format for local files with the purpose to allow them to open them directly. This feature will only work if you are running your code locally, so that your source code files are accessible to the editor.

To generate such URLs you must use the format associated with that editor:

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\Editor;
use \Fuko\Open\Link;

/* I have Atom installed locally, so this is what I want to use */
$editor = new Link(Editor::ATOM);

Once you have created the \Fuko\Open\Link object, you call its link() method to get the generated and formatted URL:

echo $editor->link('/var/www/html/index.html', 2);
// atom://core/open/file?filename=%2Fvar%2Fwww%2Fhtml%2Findex.html&line=2

The \Fuko\Open\Link::link() method is also called if you do \Fuko\Open\Link::__invoke(), so you can also just do this:

echo $editor('/var/www/html/index.html', 2);

Editor Sniff

You can sniff what editor is installed locally by using \Fuko\Open\Sniff::detect(). It will either return the editor link format found, or if nothing is found it will return NULL.

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\{Link, Sniff};

/* I have Atom installed locally, so this is how you can detect it */
$format = (new Sniff)->detect();
if ($format)
{
	echo (new Link($format))->link('/var/www/html/index.html', 2);
	// atom://core/open/file?filename=%2Fvar%2Fwww%2Fhtml%2Findex.html&line=2
}

The sniffing is done using "sniffer" functions/methods. There are some that are built-in, but you can add your own using \Fuko\Open\Sniff::addSniffer(). The sniffers must return either the format to use in the \Fuko\Open\Link constructor, or an empty string if there is no match.

$sniff->addSniffer(function()
{
	return getenv('EDITOR') === 'subl -w'
		? \Fuko\Open\Editor::SUBLIME
		: '';
});

Repo Links

There are situations in which you do not want to create links to local source code files, but instead link to your code repository. Code repo source links usually contain not just the workspace/account/project and the repo name, but also the branch/tag/commit at which you reviewing the code. To create repo links use the Fuko\Open\Repo class, which will help you to get a new \Fuko\Open\Link object with the repo link format setup inside:

include __DIR__ . '/vendor/autoload.php';
use \Fuko\Open\Repo;

$repo = new Repo(Repo::GITHUB,
	getcwd() . '/',	// cloned repo root folder which must be stripped from the link
	'fuko-php',	// workspace (aka project or account)
	'open',		// name of the repository
	'master'	// branch, tag or commit
	);

echo $repo->getLink()->link(__FILE__, 42);
// https://github.com/fuko-php/open/blob/master/tests%2FRepoTest.php#L42

There constants inside the Fuko\Open\Repo class to help you with the formats for the different source-code hosting websites:

• Fuko\Open\Repo::BITBUCKET is for Bitbucket Cloud
• Fuko\Open\Repo::GITHUB is for GitHub
