APR-Template 0.0.1

I just cut the first release of APR-Template, my Apache Portable Runtime based templating system. Since I already wrote a perfectly good README file that explains what it is, I'll just quote it here:

APR-Template is a minimalist template library implemented on top of APR and APR-Util. It's designed to provide a lightweight templating solution that fits easily into an Apache HTTPD module or other APR based program.

The template language looks like this:

<title>[% print title %]</title>
[% if add_header %]<hr>[% end %]

<h1>[% print title %]</h1>

[% for e in elements %]
<li>[% print e %]</li>
[% end %]

[% if add_footer %]<hr>[% end %]

Which produces about what you'd expect. If you've used Template-Toolkit or EZT you'll find APR-Template to be similar, although the feature set is quite stripped down, so if you find yourself trying to do a whole lot in your template it's a sign that you either need to put that logic into your C code or find a different template engine.

For examples of how to use APR-Template in a program please refer to the tmpl command line tool (in src/cmdline/tmpl.c) and the mod_template_example apache module (in examples/mod_template_example).

There's a bunch of stuff I still want to do with it (see the TODO file in the tarball for details), but the current version has just enough functionality to be useful, so I decided it was a good point to cut a release. Get it while it's hot: http://electricjellyfish.net/garrett/apr-template/apr-template-0.0.1.tar.gz


  1. It's a slow morning. Just one question: Why?

  2. Most of my reasons are discussed in a previous blog post: http://asdf.blogs.com/asdf/2005/09/fun_with_templa.html
    In short though, I want something lightweight that integrates with APR so it's easy to plug into an Apache module so that people aren't tempted to create their HTML interfaces via the equivalent of printf.

  3. You computer people need to get new acronyms. APR is taken and it doesn't mean good things.
