DSL with a free text [message #1769897] Fri, 04 August 2017 18:35 Go to next message

Hi,
I am trying to implement a parser for not very formalized DSL that already exists and cannot be modified.
It looks like the following:

~Instruction name: 
VABS16

~Instruction Description:
Vector Absolute 16-bit Word Parts
Other multi line input

~More structured section
Number1 Name1 Args1
Number2 Name2 Args2


Would you please advise how my parser and terminals should be implemented for free text multi line input where tilde starts a new section?
I think that state dependent lexer is required for this purpose. Is it possible to accomplish this within Xtext?

Thank you

Hi,

the super naive approach does not work for you?

Model:
	sections+=Section*;
	
Section:
	value=SECTION_VALUE
;

terminal SECTION_VALUE 	:
	'~' !('~')*
;
