Hi,
I am not sure what you mean when you say an object that knows how to add to the result.
Basically, you would need to build for each production the object and collect the
meaningful ones in the outer scope.
Here is something that would work for your example:
a := 'AAA' asParser ==> [:token | #a].
b := 'BBB' asParser ==> [:token | #b].
c := 'CCC' asParser ==> [:token | #c].
meaningful := a / b / c.
other := (meaningful / #newline asParser) negate star flatten.
log := (meaningful / other) delimitedBy: #newline asParser.
result := log end parse: 'AAA
AAA
BBB
CCC
AAA
other text
CCC
BBB
other text'.
result select: #isSymbol
I am CC-ing the moose mailing list because these questions tend to find better answers
there.
Cheers,
Doru

Hi all,
First of all thanks for the amazing work and aswers to all. Having said that, the
problem:
I need to parse a log, a model that represents the lo is the following:
'
AAA
AAA
BBB
Line I don't care which can contain anything that is not AAA BBB or CCC
CCC
AAA
CCC
BBB
Line I don't care which can contain anything that is not AAA BBB or CCC
'
I manage to write the grammar which parses this, but then I would lilke to have all the
log info digested on a result object which behaves something like this:
resutlObject as size --> 3
resultObject bs size --> 2
restulIbject cs size -->2
The option that im using now is that individual parsers (meaning the parser for
AAA,BBB,CCC,etc) actually retunrs an object that knows how to add themselves to the
result and then, I iterate over the parser's array result asking to each object to add
itself to the result.
Is there a better solution?
Thanks to all,
Juan.
