plantuml doesn't support latex

[catap (Kirill A. Korinsky)]

Any attempt to use plantum to render something with latex produces a error like that:

Looks like it has missed dependencies ;)

[judaew (Vadym-Valdis Yudaiev)]

This looks like the missing graphviz optional dependency. Try to install graphviz and try again. If all goes well, I will make the following changes to the port notes:

notes "
graphviz port is optional -- you don't need this if you only need sequence
and activity diagrams. Otherwise, install with
 
    sudo port install graphviz
"

If you get an error again, then send a minimal example of your diagram.

Replying to judaew:

My machine has installed graphviz and textlive-full, so it isn't something like that.

If you get an error again, send a minimal example of your diagram.

Sure,

@startuml
-> test: <latex>\epsilon</latex>
@enduml

It should be rendered like that: ​http://www.plantuml.com/plantuml/uml/SoWkIImgAStDuTArKoX9BIwnKh39IIn9hR2BIIqepip9pxFHX_2v75BpKe0A0G00

[judaew (Vadym-Valdis Yudaiev)]

Thanks, your example helped a lot.

I created a PR with the fix: ​https://github.com/macports/macports-ports/pull/11092

Feel free to leave feedback or reopen the ticket.

result with your minimal example
