I am using parsing combinators in scala
If I have recursive parser:
val uninterestingthings = ".".r
val parser = "(?ui)(regexvalue)".r | (uninterestingthings~>parser)
How can I check how many characters of input my parser consumed?
There is a
positionedcombinator that (to quote its documentation) “decorates a parser’s result with the start position of the input it consumed.”
