Question

What is the Syntax for "for" loop in Plantuml

Comments

Please show what you want, what type of diagram?

Did you try to google e.g. plantuml for loop

and look at the hit (in my case the top one): http://plantuml.com/sequence-diagram

Hi,

i want the "for-loop" syntax for Activity diagram.

i did try to google, but i didnt get the ones for activity diagrams.

the ones mentioned for sequence diagram doesnt work for me.

Yes, can I use for loops across the PlantUML language, irrespective of object type? :)

Answer 1

I guess you can represent a FOR loop in an activity diagram using a repeat while loop, eg

@startuml
start

repeat :For i=1 to 10;
  :print i;
repeat while (next i)

stop

@boldandbusted - I don't understand your question "can I use for loops across the PlantUML language, irrespective of object type?".  I mean loops only really make sense when you are drawing an activity diagram...  Did you have a diagram type in mind?

@Martin Thanks for chiming in. I'm not looking for support for *diagramming* a for loop - I know that's in there. What I'm looking for is a way to *execute* for loops within the PlantUML language. But, I think I found a workaround approach that uses "!while" loops, with some problems for me, but that's covered in another post I created a few minutes ago. :)

Hello all,

Yes, on Preprocessing you can use:

• While loop: 
  https://plantuml.com/en/preprocessing#7771e9f2c2e2630a

or 

• Loop [foreach] (but on json var):
  https://plantuml.com/en/preprocessing-json#d490ce0984282944

If that can help,
Regards.
