digitalmars.D - EBNF for D?

Two related questions:

1. Do the EBNF statements scattered throughout the D specification form a
complete description of the D grammar?

2. Is there a "non-scattered" version of the grammar available?

kind. As for part 1, the grammar is incomplete and wrong, but only in a few tiny places. I'm working on fixing them and am going to submit a patch to Walter in a few days. This is a result of something connected with part 2; I have a sed script that extracts the grammar from the HTML and converts it to EBNF (or a dialect there of) I'll release it if anyone is interested.

Of course! Mention it in Announcements when you've put it somewhere!

Out of curiosity, is the grammar in the docs complete and correct? I remember that it didn't used to be, but there's been a bunch of work on it since then. Sean

compleat, I haven't a clue. Correct, I have a list of about 6-10 (small) errors that I need to fix, so No. As to if that will match what DMD does, again, I don't know. (but I have a feeling, I'm going to find out dang quick as soon as I find time to start looking.)

It's posted: http://www.dsource.org/projects/scrapple/browser/trunk/dparser the relevant files are: "cut_gram2" and and "gram.sed". "cut_gram2" is a bash script that runs the sed script and does a little filtering. Call it from the directory containing the .html docs or pass it the directory as the first arg. The output will end up in "gram.inp" and isn't quite right (formatting errors and whatnot) I have another program that will convert it to something usable (and also factor out left recursions) but it's not ready for posting. p.s. It is intended to be run on the doc as patched by me. With any luck, Walter will get my edits in post haste.
