Installation

Simply download the plugin, place the entire folder in your WordPress /plugins/ folder, and activate.

Usage

It currently uses Clickatell’s gateway services, though more could be supported in the future. Once you get login credentials to Clickatell’s http gateway you can start sending messages easily.

Simply instantiate the class with your credentials:

$mysms = new wpSMS( $API_ID, $USERNAME, $PASSWORD );

Then send your message:

$mysms->send( $YOUR_MESSAGE, $TO_PHONE_NUMBER );

How you create the message or get the destination phone number is up to you.

Screenshots

• You’ve found an interesting book in our library, but who wants to write down the location and call number when you can text it to yourself?
  
• Clicking the “text this to me” link takes you to a screen where you preview the message and enter your mobile number.
  
• The received message includes all the details you need to find the book on the shelf.
  

hmm-citation-extractor, ParsCit and FreeCite (not to be confused with FreeCite, the F/OSS EndNote-like app). FreeCite is available as a service and a download.

Still, wouldn’t a simple URL be easier than all these unstructured citation formats?

WordPress 2.5.1 added a really powerful feature to register_taxonomy(): automatic registration of permalinks and query vars to match the taxonomy. Well, theoretically it added that feature. It wasn’t working in practice. After some searching yesterday and today, I finally found the bug and worked up a fix. I made a diff and set off to open a ticket in Trac.

On the one hand I’m glad I searched first, because it turns out that a ticket on the very same issue was opened on May 16th and it already has a fix. On the other hand, it’s kind of a kicker to have lost my chance at reporting the bug and submitting a fix by only a few days.

The fix is committed for WordPress 2.6, but I’ve done a workaround for 2.5.1 (workarounds are easier to manage than core code changes). I’d say I wish I searched Trac first, but I wouldn’t have known what to search for if I didn’t figure out how to fix the bug first. And I guess I really can’t complain about a community that quickly finds and fixes bugs.

It was part of a long thread among WordPress hackers over the summer and fall, but this post at VulgarisOverIP just reminded of it: minify promises to be an easy way to compress external CSS and JavaScript without adding extra steps to your develop/deploy process. No, really, look at the usage instructions. (To be clear, the Vulgaris and Google Code versions are different, one derived from the other and backported to PHP4 compatible. Still, the concept is the same.)

Vulgaris reports a nearly 300% decrease in time to download, definitely worth the effort.

WordPress 2.0 introduced some sophisticated HTML inspecting and de-linting courtesy of kses.

kses is an HTML/XHTML filter written in PHP. It removes all unwanted HTML elements and attributes, and it also does several checks on attribute values. kses can be used to avoid Cross-Site Scripting (XSS), Buffer Overflows and Denial of Service attacks.

It’s a good addition, but it was also removing the class names from some of the elements of my posts. The result is that the following structured XHTML was coming through without any structure.

<ul class=“fullrecord”>
<li class=“title”><h3>Title</h3>
<ul>
<li>The Effects Of A Modified Ball In Developing The Volleyball Pass And Set For High School Students</li>
</ul>
</li>
<li class=“attribution”>...

Without the semantic value of the classnames, the XHTML loses all the microformatting, making it not only less re-usable/remixable but also harder to style.

<ul>
<li><h3>Title</h3>
<ul>
<li>The Effects Of A Modified Ball In Developing The Volleyball Pass And Set For High School Students</li>
</ul>
</li>
<li>...

A WordPress form post pointed me to the includes/kses.php file, where the $allowedposttags array set the standards for the acceptable tags and attributes. It begins like this:

$allowedposttags = array ('address' => array (), 'a' => array ('href' => array (), 'title' => array (), 'rel' => array ()...

It’s a hack, but changing the entries for some of the tags got me through.

'ul' => array ('class' => array())

(some of the non-printable characters have been replaced with newlines for readability.)

After staring at that record for entirely too long, forgetting about it for a while, then returning again to think about how unreadable it was, then forgetting about it again, then taking one last look, I had that *duh* moment that made me realize what I should have seen on first glance: this is a MARC record that hasn’t had its directory parsed.

So here’s my short-but-handy-and-hopefully-usefull-to-somebody-sometime code to parse the directory and then the rest of the record. It assumes $records is an array of records.

foreach($records as $record){
	$temp = explode('', $record);
	$dir = $temp[0];
	$record = substr($record, (strlen($dir) + 1));

	$dir = substr($dir, 24);
	$dir_field = NULL;
	while($dir){
		$dir_field[] = substr($dir, 0, 12);
		$dir = substr($dir, 12);
	}

	$record = str_replace('', '|', $record);
	$marc = NULL;
	foreach($dir_field as $field){
		if(ereg_replace('[^0-9]', '', $field)){
			unset($temp);
			$len = substr($field, 3, 4);
			$pos = substr($field, 7, 5);
			$field = substr($field, 0, 3);
			$temp = substr($record, $pos, $len);
			if($field < 10)
				$temp = '  |'. $temp;
			$marc .= trim($field .'|'. $temp) .“\n”;
			$marc_array[$field] = $temp;
		}
	}
	echo $marc;
}

The actual output of that code on that record is this:

It includes a little bit of fudging that my other MARC parsing code demands, but works and is readable.
