Triangle?

[BBX999]

Might it be possible to draw a triangle with text in it, similar to the current rectangle syntax? Or a circle for that matter (I currently achieve a circle with a very high value for the rectangle round corners using a stereotype). Thanks!

Would this be hard to implement? If I wanted to work on a pull request, could someone familiar with the code base point me in the direction of which files I might need to look at / modify? Is there a resource anywhere giving a high level overview of the organization of the codebase? @The-Lum @arnaudroques

Thanks!

Hello @BBX999, and all,

---

Is there a resource anywhere giving a high level overview of the organization of the codebase?

No, it seems not...
But you can take inspiration from the latest shapes creations:

• person (added on v1.2021.4)

  • Adding new "person" keyword
  • include on plantuml/plantuml@feba014

• hexagon (added on v1.2021.1)

  • https://forum.plantuml.net/10418/please-provide-a-hexagon-shape?show=10418#q10418

  • include on plantuml/plantuml@0dc13cc

  • But here are some issues 'already closed or always open':

• hollow actor (30 Oct 2020) [:warning: but that is an actor style; not a real new shape name]

  • New actor style - Hollow plantuml#396
  • include on plantuml/plantuml@a9813ad

If I wanted to work on a pull request, could someone familiar with the code base point me in the direction of which files I might need to look at / modify?

Then here is an attempts of list of change for new shape creation:

1. Adding your new shape name in:

• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/graphic/USymbols.java
• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/descdiagram/command/CommandCreateElementFull.java

2. Create your new shape with a new file USymbol<ShapeName>.java on this directory:

• https://github.com/plantuml/plantuml/tree/master/src/net/sourceforge/plantuml/graphic

3. Adding your shape name on param & style:

• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/style/SName.java
• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/style/FromSkinparamToStyle.java
• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/FontParam.java
• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/ColorParam.java
• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/LineParam.java
• Depending if your shape have round corner: https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/CornerParam.java

4. Adding your shape name on language:

• https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/syntax/LanguageDescriptor.java

5. Test...

If that can help,
Regards.

That would be very useful for me as well!
