Hi,
I need to accept statements like:
"a" and "b" and "c"
and retrieve the quoted strings (i.e. "a", "b", and "c").
When it didn't work as expected I decided to boil it down to its simplest
components. I would expect the following to match, but it doesn't:
ruleA : QUOTED_TEXT 'and' QUOTED_TEXT 'and' QUOTED_TEXT;
QUOTED_TEXT : '\"' ( options {greedy=false;} : .)* '\"'
{ setText(getText().substring(1, getText().length() - 1)); } ;
With the text '"a" and "b" and "c"' (without the single quotes) it produces
the following output:
line 1:8 mismatched character '"' expecting 'w'
line 1:19 required (...)+ loop did not match anything at character '<EOF>'
line 1:9 mismatched input 'b' expecting 'and'
Changing ruleA so one of the quoted strings is replaced by the QUOTED_TEXT
lexical removes any errors. For example, the following ruleA definition
works:
ruleA: '"a" and' QUOTED_TEXT 'and "c"';
So, my question is, what have I missed? (This is using IDEA 8 with the
latest antlr works plugin by the way).
Many thanks,
Col
