[SimpleParse] Having SimpleParser ignore whitespaces

[Karl T. K. <ka...@pr...>]

Hi fellow parsists.

I notice that all of the example grammars include whitespaces in the
productions explicitly. Is there any simple way to tell SimpleParse that
the charset "[ \t\n\r]+" is considered a generic token separator, as is
customary with other EBNF tools ? 

funcall := id, '(', arglist, ')', ';'

is most definitely easier to read and reason about than

funcall := id, ws, '(', ws, arglist, ws, ')', ws, ';'

I tried modifying the resultant tuple returned by generator.buildParser
thusly;

parser = generator.buildParser(decl).parserbyname('root')
parser = ((None,TextTools.AllInSet,TextTools.set(' \r\n\t'),+1),) + parser
pprint.pprint( TextTools.tag( input, parser ))

but that does not seem to have any effect.

Any suggestions/pointers to solutions are most welcome.


Kind regards,

Karl T
