[darcs-devel] [patch1969] : remove graphviz dependency by re-implementing show dependencies

[Ben Franksen]

Ben Franksen <ben.franksen at online.de> added the comment:

It was surprisingly easy to re-implement the main functionality from first
principles. I also find it remarkable how much cleaner the code has become.
The output of the new 'show dependencies' command differs in two points: it
uses a hex rendering of the shortened (to 32 bits) patch ID as the node
identifier. It also contains edges for all direct dependencies which I find
more useful than reducing the graph to avoid transitive edges by arbitrarily
deleting them.

  * move getDeps and SPatchAndDeps from D.P.Depends to D.UI.C.ShowDependencies
  
  This somewhat messy code has no relationship with anything else happening
  inside D.P.Depends. Besides, getting rid of the graphviz dependency may
  involve re-writing at least parts of that code, which will be easier if it
  is concentrated in D.UI.C.ShowDependencies.
