asked Apr 7 in Question / help by The-Lu (4,780 points)

For example, if we add a team for each participants ; and a new field color:

!$data={"partlen": "2", "game": "GamePlantuml", "participants": [
{"name": "XYZ" ,"as": "xyz", "team": "A"},
{"name": "RST" ,"as": "rst", "team": "B"},
{"name": "UVW" ,"as": "uvw", "team": "B"}],
"color": {"A": "red", "B": "blue"}
}

How to access to the color of the team, from a participant on a foreach loop?

According to: the last answer and the usage of '%string()'

We test:

  1. :access to json: [$data.color.A, $data.color.B] $part.team -> $data.color.%string($part.team);
  2. :access to json: [$data.color.A, $data.color.B] $part.team -> $data.color[$part.team];
    
  3. :access to json: [$data.color.A, $data.color.B] $part.team -> $data.color.($part.team);
    
  4. :access to json: [$data.color.A, $data.color.B] $part.team -> %get_variable_value($data.color,".",$part.team);
    

But with no success.

  • Is it possible with te current version?
  • or is it on the road map of a new release?

Here is the full code:

@startuml
!$data={"partlen": "2", "game": "GamePlantuml", "participants": [
{"name": "XYZ" ,"as": "xyz", "team": "A"},
{"name": "RST" ,"as": "rst", "team": "B"},
{"name": "UVW" ,"as": "uvw", "team": "B"}],
"color": {"A": "red", "B": "blue"}
}

:a;
!foreach $part in $data.participants
  :$part.name as $part.as;
  :access to json: [$data.color.A, $data.color.B] $part.team -> $data.color of $part.team;
  ':access to json: [$data.color.A, $data.color.B] $part.team -> $data.color.%string($part.team);
  ':access to json: [$data.color.A, $data.color.B] $part.team -> $data.color[$part.team];
  ':access to json: [$data.color.A, $data.color.B] $part.team -> $data.color.($part.team);
  ':access to json: [$data.color.A, $data.color.B] $part.team -> %get_variable_value($data.color,".",$part.team);
!endfor

Thanks for the feedback.

This is fixed in last beta http://beta.plantuml.net/plantuml.jar

@startuml
!$data={"partlen": "2", "game": "GamePlantuml", "participants": [
{"name": "XYZ" ,"as": "xyz", "team": "A"},
{"name": "RST" ,"as": "rst", "team": "B"},
{"name": "UVW" ,"as": "uvw", "team": "B"}],
"color": {"A": "red", "B": "blue"}
}

:a;
!foreach $part in $data.participants
  :$part.name as $part.as;
  :1 access to json: [$data.color.A, $data.color.B] $part.team -> $data.color of $part.team;
  :2 access to json: [$data.color.A, $data.color.B] $part.team -> $data.color[$part.team];
!endfor
