Hi Sean,
#negate is the way to go. #not does not consume the stream.
Cheers, Doru

I've been playing with PetitParser and I keep running into what seems like a common case. I want to skip everything up to the first match of my second parser. For example, if I don't care about anything in a string that comes before 'dd', I write: parser2 := 'dd' asParser negate plus, 'dd' asParser ==> [ :nodes | nodes second ]. parser2 parse: 'kslkxjclkxjcdd'. "Returns 'dd'"
This gets the job done, but seems awkward. What's the most elegant way? I thought maybe "'dd' asParser not plus, 'dd' asParser." But the image just hangs.
