I mostly switched from MetaPost to Asymptote for generating my figures.

One thing that I found useful in MetaPost (or more specifically, MetaFun) was the debugging routines such as drawwholepath which renders the details of a given path. This is may be used to determine subpaths for commands such as buildcycle or just to analyse or refine a path coming from a library.

It seems Asymptote is not (yet) equiped with such debugging routines, so here is my attempt.

Here is a simple path, drawn normally and then with my debugging routine.

• The routines debug.asy
• The simple path simple.asy
• The debugged path debugged.asy
