I'm a new DocuWiki user. I'm going to use it mainly for my teaching materials, which are mainly about programming.
I have specific needs for source code presentation: I need not only code highlighting (which is quite simple nowadays to achieve), but also some specific parts of the code to be marked (with some coloured box, or something like this), some arrows pointing at specific places in code, or some text comments. Something similar to the attached image.
There are many ways to achieve these goals, and I think that the best way would be to use HTML/CSS code for code highlighting, embedded into SVG element, and then render all the remaining text/graphics objects with SVG elements.
Is there such a plugin for DocuWiki, or should I write it by myself?
