I see you are not the only one who started writing string array
literals like this:
enum PEGCode = grammarCode!(
"Grammar <- S Definition+ EOI"
,"Definition <- RuleName Arrow Expression"
,"RuleName <- Identifier>(ParamList?)"
,"Expression <- Sequence (OR Sequence)*"
);
IOW comma on the left side. I know it's not a style preference but
actually a (unfortunate but needed) technique for avoiding bugs. :)
So can you use this to actually parse D code, extract syntax trees and
stuff like that? I'm clueless about parsing but it looks very neat.
Nice work!
