Filter for typography

Recently Igor Kononuchenko laid out a version of a typographer written in Python . Igor thanks a lot. And I modestly decided to make a typographic filter for django from the library. Not that it is difficult - but for beginners, like me, it can be useful. What actually happened.

1. To start, downloaded through SVN library from Google code: http://code.google.com/p/typo-py/ .

2. As a guide in writing filters turned to official documentation .
')
3. I did tests on a previously written Portfolio model - hence, such paths turned out. The file typographus.py put in mysite / portfolio / templatetags (don’t forget to put an empty __init__.py file there). At the end of the file I added the filter code itself:

from django import template
register=template.Library()

@register.filter
@stringfilter
def typographus(string):
"""Russian typorgify"""
if type(string) is not unicode:
string = unicode(string)
return Typographus().process(string)


4. In the settings.py file in the INSTALLED_APPS list, added a line, mysite.portfolio.templatetags.typographus , which connects the handler.

5. In the html-template we got the following code:

{% extends "base.html" %}
{% load typographus %}
...
{% block content %}

{% autoescape off %}
<h1>{{ portfolio.title|typographus }}</h1>
{{ portfolio.text|linebreaks|typographus }}
{% endautoescape %}

{% endblock %}


That's all. In the process of writing, I managed to run into a little problem: the typographer himself requires a line in utf8, and if a filter chain is used (for paragraph breaks : {{portfolio.text | linebreaks | typographus}} ), an error is generated . Therefore, in the filter itself there is a check for the type of the string and a conference in utf8, if necessary.

I learned a little crumpled - I just recently used Django - if where I was wrong, correct me. And thanks again to Igor for the typographer.
