Issues with SDL final separator for latex or math expression [in Activity-Beta]

Question

Hello PlantUML team,

To continue with: https://forum.plantuml.net/11320/latex-command-requires-space-between-activity-object

We observe the same issue with some other end SDL separator:

With /

:<latex>P(y|\mathbf{x}) \mbox{ or } f(\mathbf{x})+\epsilon</latex>/

[Click to image to see all code on PlantUML server]

With }

:<latex>P(y|\mathbf{x}) \mbox{ or } f(\mathbf{x})+\epsilon</latex>}

With >

:<latex>P(y|\mathbf{x}) \mbox{ or } f(\mathbf{x})+\epsilon</latex>>

Idem With <

And for |, we observe:

:<latex>P(y|\mathbf{x}) \mbox{ or } f(\mathbf{x})+\epsilon</latex> |
:<latex>P(y|\mathbf{x}) \mbox{ or } f(\mathbf{x})+\epsilon</latex>|

If that can help to test,
Regards,
Th.

Probably the idea of changing the final ; separator for SDL by another character was a bad idea beacause it's confusing for the parser.

Instead of changing this final separator, we could use stereotype instead.

So for example, instead of:
:this is an example|

We could have:
:this is an example; <<task>>

Or another example:
:demo<

would become:
:demo; <<input>>

What do you think about it?

Here are the actual possibility and we are out of inspiration for most of them:

•     <   <<input>>
•     >   <<output>>
•     /   <<foo1>>
•     \   <<foo2>>
•     ]   <<foo3>>
•     }   <<foo4>>
•     |   <<task>>

Hi,

IMHO that seems good;
And conform with all the PlantUML philosophy... (as stereotype: port, end, join,...)

The last question will be:

• How to manage multi-line ?

:demo
multi line; <<input>>

and how manage special char on multi-line, as:

:demo
multi line 1
multi line >>
; <<input>>

or 

:demo
multi line 1
multi line >>; <<input>>

and the worst:

:demo
multi line 1;
multi line >>
; <<input>>

:demo
multi line 1;
<<input>>
multi line >>
; <<input>>

For multi-line:

• Is it necessary to oblige `;` on the begin of the line....

And some questions arise as:

We've just published a new snapshot that support the new syntax:

Any though about stereotype names? We are not sure they are the right one.

Thanks!

That seems good.

But we can ask the question on PlantUML Github Discussion to confirm...

Regards.
