It seems we observe the same issue with ditaa:

@startuml
ditaa
+--------+   +-------+    +-------+
|        +---+ ditaa +--> |       |
|  Text  |   +-------+    |diagram|
|Document|   |!magic!|    |       |
|     {d}|   |       |    |       |
+---+----+   +-------+    +-------+
    :                         ^
    |       Lots of work      |

About ditaa, for some historical reason, you now have to use this.

Tell us if it's a big issue for you.

Hi @arnaudroques,

For ditaa:

Tell us if it's a big issue for you.

No: That is not an issue for me.
But, we must:

1. update the doc. [on alphadoc/.../ditaa] (already just done, awaiting your approval)
2. verify sub-digram management...
   But that is another wanted feature...:

node n [
{{ditaa
+---------+  /--------\   +-------+
| cBLU    +--+cAAA    +---+Version|
|         |  |  Data  |   |   V3  |
|    +----+  |  Base  |   |cRED{d}|
|    |cPNK|  |     {s}|   +-------+
|    |    |  \---+----/
+----+----+    
}}
{{ebnf
a  = "a";
}}
]

Regards.

As said in #1232, we are going to put back help themes et help font, since they are useful.

[arnaudroques]

This should be fixed in last snapshot.
Tell us if it's not working for you!

Thanks a lot.

If you want to suppress Help...
Perhaps change the name...
Like:

• Listfonts
  Why not:
• Listthemes

To debate...
Regards.
