Failure to generate diagram in PlantUML converted files

[ronaldtse]

It seems that the converter includes the <CR> symbols and outputs them, which crashes LutaML:

diagram IsoDoc_IsoBibliographicItem {
  
  
  
  class BibliographicItem <<Bibliography>> {
  
  }
  
  class IsoBibliographicItem{
      +docIdentifier: IsoDocumentId

Actually it still doesn't work after removing <CR> symbols. Will await @w00lf for investigation.

The actual code is here: metanorma/metanorma-model-iso#60

The error was because of a redundant <<enumeration>> keyword on enum type entity:

enum <<enumeration>> {
....

Removed it, pushed changes

@w00lf thanks! Can the LutaML parser throw out the exact error so the user knows how to fix it?

I am looking for a way to do that, the library that we are using for dsl parsing - parslet does allow it, but its not trivial to configure

[w00lf]

@ronaldtse created an enhancement task for that

Thanks @w00lf ! Let's close this then.
