lex class definition for "C language" string

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm trying to define lex class definition for C strings. First step was to take a class definition from one already defined in codejock samples. It looks like below (taken from file _cpp.schclass):

lexClass: 	
	name			= c_String	
	parent:dyn		= c_CPP, c_CPPCodeBlock
	children		= c_URL
	start:Tag		= '"'
	skip:Tag		= '\\"', '\\\r\n', '\\\n\r', '\\\n', '\\\r'	
	end:Tag			= '"', @eol
	txt:colorFG		= 0xE00000
	DisplayName		= 'String (Double Quotes)'

Class above does not cope well with text like one below:

"c:\\fdsasdf\\" + 333.3

result:
whole line is colored like text

expected:
only text between quotes is colored like text

To fix this issue I thought that when I additionally skip '\\' it will to the job but this didn't help.

Does anyone have an idea how to define C like string lex class to cope well with scenario described above?

	you have to change the skip:tag section, so that it looks like that: lexClass: name = c_String parent:dyn = c_CPP, c_CPPCodeBlock children = c_URL start:Tag = '"' skip:Tag = '\\\r\n', '\\\n\r', '\\\n', '\\\r' end:Tag = '"', @eol txt:colorFG = 0xE00000 DisplayName = 'String (Double Quotes)' But if you would like to get something like this: 1 "c:\\fdsasdf\\" + 333.3 2 3 "c:\\fd\n\r 4 5 sasdf\\" + 333.3 You need to change it to: lexClass: name = c_String parent:dyn = c_CPP, c_CPPCodeBlock children = c_URL start:Tag = '"' skip:Tag = '\\\r\n', '\\\n\r', '\\\n', '\\\r', '\n', '\n\r', '\r\n', '\r' end:Tag = '"', @eol txt:colorFG = 0xE00000 DisplayName = 'String (Double Quotes)' Best regards Flashermail
