[antlr-interest] caseSensitive = false in C taget ??

[Indhu Bharathi]

AFAIK, there is no shortcut.

You will have to write something like

HELLO	:	( ('H'|'h') ('E'|'e') ('L'|'l') ('L'|'l') ('O'|'o') )
	;


You can make it more readable using fragments.

HELLO : H E L L O

fragment H: ('H'|'h')

fragment E: ('E'|'e')

fragment L: ('L'|'l')

fragment O: ('O'|'o')


If you don't care about case in the complete text, you can consider creating
your own Stream subclassing StringStream or write a wrapper on top of it and
emit all characters in lower case. Then you parser needs to handle only
lower case.

Cheers, Indhu
