I have something that works, but it is not as clean as I had hoped.
Problem:
Take existing html files and replace the <pre> decorated inline
code examples with pygments.
First idea for solution:
Somehow let mako know to send out some bits of each html file
to be decorated.
Flow:
1. A user chooses Articles from the web menu.
2. A user chooses to view mysample_article.
3. Routes hands the request to the articles controller.
4. That controller hands info to the articles.mako template.
5. That template inherits the base.mako template
-and- includes the chosen article in its body.
Inside that article are blocks of code to be decorated.
6. The whole thing is combined and served
I had hoped to update old articles with pygments by just replacing
<pre> tags like this
<code style="shell">
.. some shell commands ..
</code>
and somehow teaching mako to interpret that and process. But I got as
far as quoting the code bits in the html file as a string and sending
that out to be processed by way of a namespace and defined function.
This works, but there must be a cleaner way. I am new to this and open
to ideas. Does anybody have any suggestions?
Some details:
Here is a snipped tree.
==============================

|-- articles
| `-- mysample_article.html
|-- components
| `-- pygments.mako
`-- pages

`-- articles.mako

==============================
<%namespace name="mypygments" file="/components/pygments.mako"/>

if not lang:
lang = "python"
lexer = get_lexer_by_name(lang.strip('"'), stripall=True)
formatter = HtmlFormatter(linenos=True, cssclass="friendly")
result = highlight(code, lexer, formatter)
%>
<div id="highlight">${ result }</div>
</%def>
