As Ekaitz has been doing some great PEG work and it seems that there's some renewed interest in PEG, please find a newer version of this patch as a broken-up patch set and rebased on latest main. It features: * debug tracing, for debugging of grammar * expectation parser, for (syntax) error reporting * parameterize'able whitespace and comment skip parsing * preserving of location information * fall-back parsing, for parsing incomplete texts We've been using these extensions in Dezyne (https://dezyne.org) for some years now.
