Il left a comment in your earlier post about “Packrat parser with left recursion” which seem to have been eaten by WordPress.
It was about the same topic, which I recently implemented: https://forge.ocamlcore.org/projects/lrttparser/
BTW, thanks for the idea of writing the grammar directly as an Ocaml tree, this greatly saves on unnecesary fiddling with intermediate files.
I am Richard W.M. Jones, a computer programmer. I have strong opinions on how we write software, about Reason and the scientific method. Consequently I am an atheist [To nutcases: Please stop emailing me about this, I'm not interested in your views on it] By day I work for Red Hat on all things to do with virtualization. I am a "citizen of the world".
My motto is "often wrong". I don't mind being wrong (I'm often wrong), and I don't mind changing my mind.
This blog is not affiliated or endorsed by Red Hat and all views are entirely my own.
