Agenda

• Tool shed update
• Model class proposal and prototype implementation
• Eric & Tom proposal for molecular graphical data

Tool shed update

• Committed and in the repository
• Currently checks local installs and builds local database
• Significant restructuring of Makefile
  • Install into app tree is done by building wheel file in build tree and moving into the app tree
  • What's not done is moving the wheels into a standard location
• Users will use Chimera2's built-in web browser to select new tools for install
• Source tree organization for tools -- all tools should have a setup.py (or setup.py.in)
  • Will handle the build and move
  • Should be a simple template
• Metadata for tools come from the wheel, which include an "info" file that include all of the standard and Chimera2-specific metadata

Model class proposal and prototype implementation

• Now model class is a sub-class of drawing
• Export function is part of the drawing class
• Next step is making it also a subclass the session state API to support saving and restoring sessions
• Issue: how do we handle reading data from a saved session into a current session?
  • Restore new session into it's own session object
  • Merge them (will have a lot of "fixup" to do)

Molecular graphical data proposal

• Approach is to use the same approach as Chimera1. This avoids some ugly things in the C++ layer.
• How do we decide which attributes are in the C++ layer?
  • All core graphical attributes are in C++ layer
• For external developers, need to decide on the recommended approach for adding attributes for high performance
  • Not on the list for February
  • Need to think more about this
    • Would be nice to support in the C++ layer
    • Should integrate with Render by attribute

Other notes

• Greg will be adding a precommit hook to lint the python code before you commit
  • We're going to try it, but Greg will send out instructions on how to override the precommit hook

Next Meeting

• Greg: Model API
• Eric & Tom: Initial proposal for the set of C++ attributes that's part of the molecular graphical data proposal
• Conrad: Tool Shed local repository server demo
