314 specific error messages (as of version 0.7.0)
The compiler supports 314 dedicated error or warning messages that precisely explain any problem that the compiler has identified in your sources. Each message refers to the paragraph in the OTJLD that is being violated by the problem at hand. The Problems view of the OTDT furthermore offers an option "Go To Language Definition" in its context menu for quickly navigating to this exact paragraph for further reference.
8 OT/Equinox plug-ins (as of version 0.7.0)
  • 8 Plugins of the OTDT are built using the OT/Equinox technology for adapting existing plugins. These OT/Equinox plugins comprise
  • 77 team classes
  • 206 bound role classes
  • 280 callin bindings
  • 258 callout bindings
  • approx. 19,400 PSLOC (physical source lines of code)
  • the following plug-ins are adapted by the above:
