NOTE:

parser and code templates are not perfect. There is planty of cases that is not yet covered or supported. Basic scenarious should work.

Problems?

• If puml2code causes error like:

  Error: line: 21 column: 3: SyntaxError: Expected "'", "--", "..", "__", "abstract ", 
  "class ", "hide empty members", "interface ", "namespace ", "note ", "skinparam", "title ",
  [ \t], [#], [+], [A-Za-z_], [\-], [\n], [\r\n], [^ ,\n\r\t(){}], or [}] but "{" found.

  it's most probably because PEG.js based grammar does not have support for plantuml format you have in input file.

  What should I do?

  Please raise ticket with example plantuml file that does not work

• generated source code does not look like you expected

  What should I do?

  Please raise ticket with example plantuml file and generated source code with some description how it should look like.

NOTE If you are able to create PR that solves your issue it would be even more wellcome.
