Help - how to handle captures and optionals about npeg

[mantielero]

Right now solved with closures:

proc parserBlocksGen():auto =
    var db:Block
    new(db)

    return  peg("delimitedBlocks", blk: Block):
              # Title
              title     <- '.' * >adoc.txt * adoc.crlf:
                db.title = $1
              attributes <- '[' * >*(1 - '[' - ']' - '\r' - '\n') * ']' * adoc.crlf:
                db.attributes = $1
              delimitedBlocks <- ?title * ?attributes * >R("blockDelimiter", adoc.blockDelimiters  * adoc.crlf ) * >*(!R("blockDelimiter") * *(1 - '\r' - '\n') * adoc.crlf) * R("blockDelimiter"):
                db.content = $2
                db.delimiter = $1

                blk.blocks &= db

let parserBlocks* = parserBlocksGen()

I will close this issue. If there is a better pattern, let me know:
