Introducing Raptor Templates: The Power of Genshi for JavaScript

Hi all,
About a year ago, when comparing popular templating languages, I came
across Genshi and was impressed by the clean syntax. Unfortunately it only
worked for Python and I was looking for a good templating solution for
JavaScript. I decided to create a new JavaScript templating language that

Hmm. That page needed a thorough overhaul. I did a new benchmark run
on my machine and updated the page with the results. I removed the
other templating engines -- I'm happy to add them back if someone is
willing to put in the effort of getting them all running on Python 2.x
and 3.x somewhere.

Re: UnicodeDecode when calling render()

hodges...@gmail.com (Simon Cross) — Tue, 25 Dec 2012 06:36:33 UT

Your original example doesn't boil down to #357. It's an encoding
issue. Genshi trunk raises:

UnicodeError: source returned bytes, but no encoding specified

and setting "encoding='latin-1'" in the construction of HTMLParse
causes your example to work.

The attached patch to Genshi 0.6.x makes the behaviour there similar.

The HTML5 standard actually describes all the cleanup procedures

HTML5Parser using [link] and patch its existing
HTMLParser to have optional fallback mechanism?

Just to chime in, I've had to deal with the difference between correct HTML

the difference between the two is huge. The amount of "garbage in, what
you probably wanted out" is staggering. I don't know if this is still

Re: UnicodeDecode when calling render()

techto...@gmail.com (anatoly techtonik) — Mon, 24 Dec 2012 10:57:39 UT

Genshi has an HTML parser, so if parser can not handle HTML that is
accepted and correctly rendered by at least three top browsers, it is of a
little use of Genshi. I used it, because Genshi comes bundled with Trac,
and it is used in a plugin that substitutes links like "issue #423" for
specific repositories with a reference to external tracker.

Re: UnicodeDecode when calling render()

hodges...@gmail.com (Simon Cross) — Mon, 24 Dec 2012 09:58:50 UT

I closed that ticket as wontfix -- cleaning up HTML seems outside of
Genshi's scope and in any case it's not clear why Genshi would do a
better job than a dedicated tool.

Same here, no problems with Python 3.2 on trunk.

What's the hold up? Better to have a Python 3 release out there and people
using / testing against it than no release at all if you're waiting for it
to be perfect. This is blocking many packages downstream from supporting
Python 3.

Having genshi in a distributed vcs, even if subversion remains as the main source for now, would help a lot.
So far there's [link] (Mercurial) and [link] (git, but empty), and I've got [link] as a git-svn mirror, but it's not showing all the tags.

Re: Genshi with Angular.JS

Assuming that Angular.js is a browser framework (not something related

typically doesn't care about what happens once you've gotten the
template output html into the browser.

This is a quirk of how Genshi is implemented (or maybe a documentation

that evaluates to False. I would probably have done 'or {}' for
clarity.

The syntax inside the py:attrs value is just standard Python.

You're right on this in the strictly technical sense. I did not suggest
this solution in this case with a good reason. Using py:attrs in such cases
usually ended up in unreadable, hard to maintain code. According to my

the number of cases are low. I suggest using py:attrs only when the value

Re: py:if statement newbie

ferenczi.vik...@gmail.com (fviktor) — Thu, 07 Jun 2012 08:57:59 UT

No, since Genshi's XML template syntax does not provide any if-else nor
switch-case like construct.
This fact does not cause so many problems in practice, since the affected
code is usually small. For example if you build up your tabs from a list,
then only the <li> element would be doubled and only at a single place. The
