[antlr-interest] Strangeness when parsing strings and spaces

[Kevin Jackson]

Hi,

I know that this is a problem with my lexer and I'm doing something
stupid, but I have a problem with simple k,v pairs of the format:

[String "quoted string with spaces and non-alhpa chars"]

My grammar
------------------

LEFT_SQUARE: '[';
RIGHT_SQUARE: ']';
STRING: 'a'..'z'|'A'..'Z';
TEXT: ('a'..z'|'A'..'Z'|' '|',')+

pair: LEFT_SQUARE (info=STRING) ' ' '"' (value=TEXT) '"' RIGHT_SQUARE
NEWLINE+ -> transform(i={$info.text},v={$value.text});

This fails with "mismatched input expecting 'Test ' expecting STRING"
(note the space that should not be present).

pair: LEFT_SQUARE (info=TEXT) ' ' '"' (value=TEXT) '"' RIGHT_SQUARE
NEWLINE+ -> transform(i={$info.text},v={$value.text});

This grabs the space and passes it to transform (which I really don't want)

Can anyone see what I'm doing wrong?  I know the answer is probably simple

Thanks,
Kev
