5.0.0 UNRELEASED

General

  • 5.x runtime can be co-installed with the 4.x series.
  • hkl.h contain all the Public API.
  • A clear separation between the public and private API was achieved, in order to propose a Long Time Support of the 5.x series.
  • c-tap-hardness library was embeded to provide the unit test framework.
  • gobject-instrospection provide the binding support. Look at this page for more informations.
  • Documentation was generated with sphinx and asymptote for the figures.
  • New diffractometers added
    • E4CH (eulerian 4 circles horizontal) geometry.
    • MARS beamline (SOLEIL) eulerian 4 circles vertical geometry.
    • SOLEIL SIRIUS KAPPA
    • SOLEIL SIRIUS TURRET
  • New Pseudo Axes engines.
    • qper_qpar
  • A not yet public hkl3d library used only by the gui allow to compute (Bullet) and display (OpenGL) collision for model described using the COLLADA file format.

Buildsystem

  • add a –disable-hkl3d flag to avoid hkl3d library compilation.
  • replace the –enable-ghkl with a –disable-gui.
  • use ./configure –help for all the options

Gui

  • Rewriten using Gtk instead of Gtkmm, in order to minimise the required dependencies.
  • Added a 3D view to display diffractometers and collisions.
  • Added the K6C 3D model.

Bindings

  • Provide the garantie via unit tests that the python API will be stable during all the 5.x lifetime.
  • For other languages look at here.
