In reply to Requesting Java AST from selection Error after Deinstal UML Lab by Frank Zillus
Hi Frank,
sorry you had issues when trying out UML Lab. We had a look at your error description and were able to reproduce it, even with UML Lab still installed. The cause is a third-party library that is updated as a dependency, when UML Lab is installed. Rapidclipse is not compatible with this newer version. Such incompatibilities between dependencies of different Eclipse plug-ins are unfortunately difficult to avoid, but we will keep an eye on this issue.
Best regards
Andreas
Sequence diagrams
Submitted by Harish Sidlaghatta on Thu, 10/31/2019 - 06:16
Does it generate sequence diagrams too, based on call stack?
Thanks,
Harish.

Hi Harish,
currently UML Lab doesn't support sequence diagrams. We have them on our road map, but we won't integrate them in the near future.

Hi Keshav,
currently UML Lab comes with built-in support for Java and PHP.
UML Lab uses XPand templates for the code-model mapping.
By creating your own templates for the C language, UML Lab can be extended with C language support.
If you need support with integrating your custom templates into UML Lab, feel free to contact us at info@yatta.de.
Best regards,
Lukas
