Hi,

Requirement is to custom color the block of code.
How can I achieve this?

Consider the below example.
<CodeBlock> which are under if(false) will not be executed. Requirement is to mark those as grayed out or any custom color. User will know that block will not be executed.


  if(true){
  
    <Code Block>

   }

   if(false){

    <Code Block>
   }



Please guide me how to proceed. Some pointers will be helpful.

Thanks and regards,
Virag Purnam

Hi,

Semantic highlighting gets called during the start of application.
I want to achieve this dynamically.
When ever any 'if statement' is false, I want to gray out the code block present inside that.
Is there any class which I can refer?

Thanks and regards,
Virag

I cannot follow you. Semantic highlighting is called when you type in the editor.
Please explain what you do

Hi Mr. Christian Dietrich,

I have implemented TokenSource interface.
In the method nextToken(), I am checking IF condition.
If condition is false, I am making all the token present in IF block as SL comment, by changing token type.

But in editor, it does not appear as SL comment color. It retains its original color.


Thanks and regards,
Virag

You can find an example for semantic highlighting in the GEF DOT project:

Thanks Mr. Tamas Miklossy for the example. I will check, if I get something out of this.
Thanks Mr. Christian Dietrich. Yes requirement does not look nice. Just wanted to give try and check the feasibility.
