I recently discussed the Google prettify tool that I started using to display colour-coded JavaScript source code in HTML.
As I mentioned there, it does a good job for all languages I looked at except C# and VB .NET, where I prefer the colour coding generated by Visual Studio, since that highlights class names defined in referenced .NET assemblies as well as the built-in .NET ones.
To retrieve the Visual Studio colour coding and insert it into my HTML page, I still use CopySourceAsHtml 3.0. It defines some CSS styles for different colours and adds the corresponding HTML span tags around the keywords to highlight them.
On Windows, I post-processed the output using a Python script pycolorize.py to read the CopySourceAsHtml output from the Windows clipboard and convert its CSS style definitions to my own ones already pre-defined in the main blog stylesheet.
Now that I am working almost exclusively on the Mac, I converted this script from Windows to Mac as well.
Thanks to the platform independence provided by Python, the only thing that needs changing is to replace the Windows clipboard access by Mac pasteboard read and write operations.
For Windows, I was making use of a Python Windows API library. Similar libraries are available for Mac as well, but the Unix pbcopy and pbpaste command line utilities offer an even simpler alternative, as demonstrated by the Pyperclip cross-platform copy and paste sample.
Here is my new Mac version of the colour-coded HTML CopySourceAsHtml output cleanup script:

Middlesex Fells Reservation
I met up with Harry Mattison of Boost your BIM yesterday, and he suggested that I might like to visit the Fells just a few miles north of Cambridge.
That was a great idea! Thank you for that, Harry.
I ended up spending all day here on the bank of the lake, reading, sleeping, watching the sun cross the sky, taking an occasional swim. My first day in months of doing almost absolutely nothing.
Friday night I visited Dance Freedom in Cambridge, the original barefoot weekly dance, continuously running for 44 years, according to their own words. I especially enjoyed it, since I regularly participate in similar events in Switzerland. One of them is the Barfussdisco in Basle, which just inaugurated its very own Bafudi facebook page.
