The way I read you is "no" as i can't reassign inside a grammar.
what i was expecting is to hack the grammar itself. something like
replacing
token col:sym<quoted> {
'"' ~ '"'
[ <( [ '""' | <-[\n"]> ]* )> ]
}
by something close to
token col:sym<quoted> {
'"' ~ '"'
[ <( [ '""' { $0 = '"' } | <-[\n"]> ]* )> ]
}
anyway: thanks for the detailed explaination. your solution is really
elegant
marc
