--------------------------
= Discussion =

* Clipped Color dialog on Windows
  - Tristan Croll reported that color choose dialog has clipped text on Windows 10 in daily build but not 1.8.
  - Tristan's screenshot shows system color chooser.
  - Worked correctly for Eric on vive.
  - Ask Tristan to try Windows Paint program color chooser to see if it is also clipped.

* Core C++ header files not found in Clipper build
  - Tristan reports Clipper build now fails unable to find core C++ header files.
  - Zach reproduced the problem.
  - Appears that bundle_builder is not adding -I flag to compile line.
  - Zach will test if ChimeraX 1.8 is working and if so figure out the change that broke it.

* Git Action automatic builds sometimes fail
  - Eric sometimes sees Github Actions automatic build fail after he makes a commit.  But daily build that night succeeds.
  - Zach asks Eric to look at what specifically failed.
  - Zach says sometimes Github fails to reach plato but then the build fails early.

* New atomspec parser
  - Eric wondering how to get some testing for the new C++ atomspec parser.
  - Probably not ready for daily build.
  - Will add debug command to enable new parser so us developers can try it.
  - C++ PEG library new atomspec parser uses makes use of exotic C++ meta-template(?) programming.  Eric can show us what it looks like at some developer meeting.

* Small-angle X-ray scattering
  - Eric asks if we ever plan on porting Opal small-angle x-ray scattering web service from Chimera.
  - Tom says probably not unless some user demand, and if then we would probably look at some newer SAX prediction method.
  - Chimera used FOXS from Dina Schneidman but no longer works with Opal discontinued.  Eric just got first bug report a few years after shutdown so not used much.

* Chimera end-of-life prep
  - Greg asked what needs to be done for Chimera end-of-life.
  - Don't ask for registration.
  - Don't have user fill out bug reports if we are no longer accepting them.

* ChimeraX test data
  - Zach copied ChimeraX test data to ChimeraX web site on plato www/data/test-data with subdirectories named after each bundle.
  - Script in chimerax/utils/sync-test-data.sh can fetch the test data and copy it into your source tree for use.
