hi everybody,

i wanted to know if it is possible to give a specific color to element types , just imagine in your grammar you have define number having INT as a type or name having String type , and you want xtext to put a specific color to the name you enter or the integer you put?

if it is possible , can you tell me how to do it .

Best regard

Hi,

the basics are covered in the Xtext documentation and there are blog posts and forum posts on the topic (search the web for Xtext semantic highlighting). Feel free to follow up in this thread with more specific questions you have.

thks for the news , but i have searched the web for what you proposed but there was nothing interesting.
my big problem is this :

i have the following xtext grammar for example :

  MUX_CONFIG returns io::MUX_CONFIG:
	{io::MUX_CONFIG}
	'MUX_CONFIG'
	'{'
		('MultiplexedAddressLines' MultiplexedAddressLines=TypeBool)?
		('AddressLineADD0' AddressLineADD0=EString)?
		('AddressLineADD1' AddressLineADD1=EString)?
		('AddressLineADD2' AddressLineADD2=EString)?
		('MuxAdd0LSB' MuxAdd0LSB=TypeBool)?
    '}'

and what i want is to give a specific color to the type element , that means for the type string i want that the walue enter and the element yes or no of the type bool have the same color but i also want that color to be different from the color of the word in quotes.
that means , base on the above grammar , imagine you have the folor editor file:

  	muxconfig MUX_CONFIG {
			MultiplexedAddressLines No
			AddressLineADD0 ggdjd
			AddressLineADD1 tgklgkl
			AddressLineADD2 jgdkd
			MuxAdd0LSB Yes
			}

so i want the No , Yes and tthe differents names like ggdjd, tgklgk or jgdkd to have a specific color..

any ideas on how to do it?

Best regard,
Frank

Take a look at
org.cloudsmith.geppetto.pp.dsl.ui.coloring.PPSemanticHighlightingCalculator
in repository cloudsmith/geppetto @ github for various ways to provide
highlighting. My implementation supports regular (token based), as well
as node based, textual based, and resource-properties based
highlighting. (Basically different ways to find an offset and a length
of text to highlight).

Hope that helps you.

You can view the logic in a browser - just go to github and navigate to
the file.

Use this link:
