Re: Printing source code intelligently with ConTeXt (with overlay)

[Gerben Wierda <Gerben.Wierda@rna.nl>]

The overlay if a prelimiary of IfSQ code inspection (http:// 
www.ifsq.org). Source code is printed with the overlay and then a  
visual inspection process is performed using the overlay to keep track  
of results.

I tried the following with a test TeX file (no landscape or line  
numbers yet):

> \defineoverlay[ifsqoverlay][\overlayfigure{IfSQ-overlay.pdf}]
> \starttext
> \setupbackgrounds[page][overlay=ifsqoverlay]
> \typefile[SQL][]{details.pls}
> \stoptext

And the start of file details.pls is:

But that ends in tears:

The overlay I am using is:

http://www.ifsq.org/resources/level-2/overlay.pdf

If prettyprinting does not work I would be happy with verbatim print  
with line numbers and correct indentation.
