TOPIC: TEXTPATTERN
Investigating Textpattern
9th March 2009With the profusion of Content Management Systems out there, open source and otherwise, my curiosity has been aroused for a while now. In fact, Automattic's aspirations for WordPress (the engine powering this blog) now seem to go beyond blogging and include wider CMS-style usage. Though some may even have put the thing to those kinds of uses, I believe that it has a way to go before it can put itself on a par with the likes of Drupal and Joomla!.
Speaking of Drupal, I decided to give it a go a while back and came away with the impression that it's a platform for an entire website. At the time, I was attracted by the idea of having one part of a website on Drupal and another using WordPress, but the complexity of the CSS in the Drupal template thwarted my efforts and I desisted. The heavy connection between template and back end cut down on the level of flexibility too. Though that mix of different platforms might seem odd in architectural terms, my main website also had a custom PHP/MySQL-driven photo gallery too and migrating everything into Drupal wasn't going to be something that I was planning. Since I might have been trying to get Drupal to perform a role for which it was never meant, I am not holding its non-fulfillment of my requirements against it. While Drupal may have changed since I last looked at it, I decided to give an alternative a go regardless.
Towards the end of last year, I began to look at Textpattern (otherwise known as Txp) in the same vein, and it worked well enough after a little effort that I was able to replace what was once a visitor dossier with a set of travel jottings. In some respects, Though Textpattern might feel less polished when you start to compare it with alternatives like WordPress or Drupal, the inherent flexibility of its design leaves a positive impression. In short, I was happy to see that it allowed me to achieve what I wanted to do.
If I recall correctly, Textpattern's default configuration is that of a blog, which means that it can be used for that purpose. So, I got in some content and started to morph the thing into what I had in mind. Because my ideas weren't entirely developed, some of that was going on while I went about bending Txp to my will. Most of that involved tinkering in the Presentation part of the Txp interface, though. It differs from WordPress in that the design information like (X)HTML templates and CSS are stored in the database rather than in the file system à la WP. Txp also has its own tag language called Textile and, though it contains conditional tags, I find that encasing PHP in <txp:php></txp:php> tags is a more succinct way of doing things; only pure PHP code can be used in this way and not a mixture of such in <?php ?> tags and (X)HTML. A look at the tool's documentation together with a perusal of Apress' Textpattern Solutions got me going in this new world (it was thus for me, anyway). The mainstay of the template system is the Page, while each Section can use a different Page. Each Page can share components and, in Txp, these get called Forms. These are included in a Page using Textile tags of the form <txp:output_form form="form1" />. Style information is edited in another section and you can have several style sheets too.
The Txp Presentation system is made up of Sections, Pages, Forms and Styles. The first of these might appear in the wrong place when being under the Content tab would seem more appropriate but the ability to attach different page templates to different sections places their configuration where you find it in Textpattern and the ability to show or hide sections might have something to do with it too. As it happens, I have used the same template for all bar the front page of the site and got it to display single or multiple articles as appropriate using the Category system. Though it may be a hack, it appears to work well in practice. Being able to make a page template work in the way that you require really offers a considerable amount of flexibility; it allowed me to go with one sidebar rather than two as found in the default set up.
Txp also has the facility to add plugins (look in the Admin section of the UI) and this is very different from WordPress in that installation involves the loading of an encoded text file, probably for the sake of maintaining the security and integrity of your installation. I added the navigation facility for my sidebar and breadcrumb links in this manner, with back end stuff like Tiny MCE editor and Akismet coming as plugins too. While there may not be as many of these for Textpattern, the ones that I found were enough to fulfil my needs. If there are plugin configuration pages in the administration interface, you will find these under the Extensions tab.
To get the content in, I went with the more laborious copy, paste and amend route. Given that I was coming from the plain PHP/XHTML way of doing things, the import functionality was never going to do much for me with its focus on Movable Type, WordPress, Blogger and b2. The fact that you only import content into a particular section may displease some, too. Peculiarly, there is no easy facility for performing a Textpattern to Textpattern migration apart from doing a MySQL database copy. While some alternatives to this were suggested, none seemed to work as well as the basic MySQL route. Tiny MCE made editing easier once I went and turned off Textile processing of the article text. This was done on a case by case basis because I didn't want to have to deal with any unintended consequences arising from turning it off at a global level.
While on the subject of content, this is also the part of the interface where you manage files and graphics along with administering things like comments, categories and links (like a blog roll on WordPress). Of these, it is the comment or link facilities that I don't use, allowing me to turn comments off in the Txp preferences. So far, I am using categories to bundle together similar articles for appearance on the same page, while also getting to use the image and file management side of things as time goes on.
All in all, it seems to work well, even if I wouldn't recommend it to the sort of audience to whom WordPress might be geared. My reason for saying that is because it is a technical tool that is used best if you are prepared to your hands dirtier from code cutting than other alternatives. I, for one, don't mind that at all because working in that manner might actually suit me. Nevertheless, not all users of the system need to have the same level of knowledge or access; usefully, it is possible to set up users with different permissions to limit their exposure to the innards of the administration. In line with Textpattern's being a publishing tool, you get roles such as Publisher (administrator in other platforms), Managing Editor, Copy Editor, Staff Writer, Freelancer, Designer and None. Those names may mean more to others, but I have yet to check out what those access levels entail because I use it on a single user basis.
Txp may lack certain features, such as graphical visitor statistics instead of the current text listings. While, its administration interface could benefit from refinement, it fulfils my core requirements. The more streamlined approach makes it more practical in my opinion, which is demonstrated by my creation of A Wanderer's Miscellany. Consider exploring it yourself to see what's possible, since I am certain that I have only scratched the surface of Textpattern's capabilities.
