[EBNF] None-first style

[toxn]

Allow for a none-first style in ebnf and regex diagrams. It could even be the default, as it tends to be more readable when using repetition over optional elements.

Hi @toxn, and all,

[Just for the record,] see some discussions on the forum (on the same topic) from:

Hi @toxn

That is not your final request but here is a possible workaround, using compact:

@startebnf
!pragma compact
compact = {something};
@endebnf

If that can help,
Regards,

Hi all,

[This is an Issue Review] 👀
This is now fixed, on next release v1.2025.1:

@startebnf
nice_on_v1-2025-1 = {something};
@endebnf

Thanks to:

• @toxn for the report.
• PlantUML team and @arnaudroques for your work.

Hi @arnaudroques, @toxn and all,

• Should the modification also be made for the simple optional?
  [in order to have the same global layout]

Very good idea!
