techfoolery We're kind of a big deal

I've been using TextMate a lot recently. It's completely replaced TextWrangler as my editor of choice, for a lot of reasons: better syntax coloring, more extensible, more customizable and insane Unix integration. You can create commands, which are code snippets in any language you can run through the terminal, and tie them to keyboard shortcuts. This is one that I created to pull up documentation from php.net for whatever function name or keyword I have selected. It is very loosely based on code from Jeff Gould.

To use this, first copy the code below. You'll want the un-styled version, so click on the "view plain text" link just above it.

#!/usr/bin/php
<?php

ob_start();
$func = preg_replace('/[() ;]/', '',  $_ENV['TM_CURRENT_WORD']);
$url = 'http://us2.php.net/manual/en/function.' . str_replace('_', '-', $func) . '.php';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Accept-Language: en-gb, en"));

$res = curl_exec($ch);
$error = curl_error($ch);
curl_close($ch);

$data = ($res) ? substr(strstr($res, "rnrn"), 4) : "Curl error: " . $error;

$data = substr($data, strpos($data, 'Swedish'));
$data = substr($data, strpos($data, '<!--/UdmComment-->'));
$data = substr($data, 0, strpos(strtolower($data), '<div id="usernotes">'));
echo $data;

$output = ob_get_contents();
ob_end_clean();

echo (strlen($output) > strlen($func)) ? $output : "Error: function " . $func . "() not found.";
?>

Next, open TextMate and go to the Bundle Editor. Create a new command under PHP and use these settings:

Paste the code into the "Command(s)" text area. Use whatever activation method you like; I use ctrl-H. Now, anytime you are editing PHP code and your text cursor is in, or next to, a keyword, just activate this command to pull up a formatted version of the documentation in a new window.
