Genshi (templating language)

Genshi can be used with several Python web frameworks, such as CherryPy, TurboGears, Pylons and web2py. Genshi was the default templating language for TurboGears from versions 1.1 to 2.3.8.

Genshi markup

Genshi makes use of namespaces to embed instructions into HTML. A typical instruction is given as an attribute, with a Python expression inside the quotes. For example, the following will render a paragraph that shows 4:

<span id="mwLA"></span><span class="nt" id="mwLQ"><html</span> <span class="na" id="mwLg">xmlns=</span><span class="s" id="mwLw">"http://www.w3.org/1999/xhtml"</span> <span class="na" id="mwMA">xmlns:py=</span><span class="s" id="mwMQ">"http://genshi.edgewall.org/"</span><span class="nt" id="mwMg">></span> <span class="nt" id="mwMw"><body></span> <span class="nt" id="mwNA"><p</span> <span class="na" id="mwNQ">py:content=</span><span class="s" id="mwNg">"</span><span class="mi" id="mwNw">2</span> <span class="o" id="mwOA">+</span> <span class="mi" id="mwOQ">2</span><span class="s" id="mwOg">"</span><span class="nt" id="mwOw">></span>This will be replaced with 4<span class="p" id="mwPA"></</span><span class="nt" id="mwPQ">p</span><span class="p" id="mwPg">></span> <span class="p" id="mwPw"></</span><span class="nt" id="mwQA">body</span><span class="p" id="mwQQ">></span> <span class="p" id="mwQg"></</span><span class="nt" id="mwQw">html</span><span class="p" id="mwRA">></span>

Because of the use of namespaces, Genshi can be used in WYSIWYG HTML editors.
