[chimera-dev] ribbon for circular molecule

[Volodymyr Babin]

Dear Sirs,

I am writing to ask for the chimera sources -- I would like to
visualize a circular molecule using ribbons. As far as I can tell,
with the current code ribbons always have ends (cannot be closed)
because of the following snipped from

libs/_chimera/Chimera.toolkit/Ribbon.implementation

696	Molecule::updateRibbonData()
697	{
698	        clearRibbonData();
699
700	        //
701	        // For each residue, find the residues before and after. 702	 
      // Note that only residues with valid guide and plane atoms 703	    
   // may be used as the prev/next residue in a ribbon.
704	        //
705	        std::map<Residue *, RibbonResidue> rrMap;
706	        Residue *prev = NULL;
                ^^^^^^^^^^^^^^^^^^^^^

Could you please allow me to check out the svn version of the
chimera or get (easily compilable) sources of a recent release.

Thank you,

Volodymyr
