Fast XML-based template engine with Genshi syntax and Jinja blocks

Project description

Kajiki provides fast well-formed XML templates

Because Kajiki’s input is XML, it can ensure that your HTML/XML output is well-formed. The Genshi-like syntax, based on XML attributes or tags, is simply beautiful and easily understood (or ignored) by web designers. But instead of the slow performance of Genshi, Kajiki compiles templates to Python code that renders with blazing-fast speed, so Kajiki can compete with the speed of Jinja, Mako, Chameleon and others. Also, one of Genshi’s misfeatures – py:match – is replaced with blocks which work like Jinja’s blocks.

By combining the best ideas out there – XML input, Genshi’s syntax and features, Jinja’s template inheritance and final compilation to Python –, Kajiki is ready to become the most widely used templating engine for web development in Python. And more features are coming soon; stay tuned!


>>> import kajiki
>>> Template = kajiki.XMLTemplate('''<html>
...     <head><title>$title</title></head>
...     <body>
...         <h1>$title</h1>
...         <ul>
...             <li py:for="x in range(repetitions)">$title</li>
...         </ul>
...     </body>
... </html>''')
>>> print(Template(dict(title='Kajiki is teh awesome!', repetitions=3)).render())
    <head><title>Kajiki is teh awesome!</title></head>
        <h1>Kajiki is teh awesome!</h1>
            <li>Kajiki is teh awesome!</li><li>Kajiki is teh awesome!</li><li>Kajiki is teh awesome!</li>

0.7.0 (2017-06-27)

  • Support for multiline ${} expressions

  • Subsequent text nodes are now squashed into a single text node. This allows translating whole paragraphs instead of single sentences.

  • Some HTML nodes that do not require being closed but is commonly considered best practice to close them are now emitted with ending tag (IE: <p>)

  • Generally improved code documentation to lower entry barrier for contributors

  • py:switch now correctly supports multiple py:case statements.

  • text inside <script> and <style> tags is no longer collected translation.

  • As py:swtich discards all its content apart from py:case and py:else statements it will now correctly report an error when the statements has other content.

  • py:else will now correctly detect spurious content between itself and py:if as the two must be consequential.

  • Improved code documentation on core classes.

0.5.3 (2016-01-25)

  • py:with statement now keeps order of variables, so that variables can depend from each other.

  • Correctness: escape HTML attribute values.

  • Correctness: Always close script tags, even in XML mode.
