Having an LR grammar would make it easier to convert for parser generators and is more conducive to building ASTs during the parse. Thanks, Kevin 40927 1 annevk 2010-10-11 12:38:41 +0000 Why two ways of defining IDL fragments? That seems far worse than having just one. And it seems unlikely we will change the existing one a lot. 40933 2 kevin 2010-10-11 19:21:47 +0000 Anne, I was chatting with Cameron about this and he suggested I add a bug entry for it. Basically, an LR grammar is typically better suited for generating ASTs than LL grammars. My preference would be to have a single grammar, as well, and for that to be an LR grammar, but I'm biased. -Kevin 48686 3 cam 2011-05-23 02:55:36 +0000 Not necessary for now, so maybe in v2. 50454 4 art.barstow 2011-06-29 16:03:49 +0000 I think this bug should be Resolved now as "Later" and considered an input for v2. 128811 5 tobie.langel 2017-07-31 09:12:07 +0000 Maintaining two grammars is a bad idea, so we'd want to do a complete switch from one grammar to the other. There are now numerous consumers of the current LL(1) grammar, so we'd need buy-in from them before organizing such a move. If someone's ready to do this work, I'd suggest starting a conversation on public-script-coord@w3.org before moving this to a GitHub issue, then a pull request. In the meantime, I'll close this as wontfix.
