Discussion

• ctypes
  • ctypes wrapping works pretty conveniently but does not handle C++ exceptions
    • Throwing a C++ exception results in core dump
  • Alternative 1: fix ctypes to catch C++ exceptions
    • Ugh
  • Alternative 2: change C wrapper to catch exception and convert to a C error, then change ctypes call to check for error
    • Possibly use template mechanism to decorate C wrapper to minimize typing
  • Keep these solutions in mind until we encounter an actual problem
• Progress updates
  • Daily build available at ​http://preview.rbvi.ucsf.edu/chimera2/builds/macosx/chimera-2.0.daily.dmg
  • Preliminary ribbon code is in but needs to be refactored (Conrad)
    • 'ribbon' and 'rcolor' commands for ribbon display and color
    • Need to refactor for secondary structure cross sections

• help system
  • User interface:
    • Add a '?' on title bar to act as help button?
    • F1 as help key?

    • Use HTML widget in Chimera 2
    • Reading in separate browser has advantages too
