| LALR look-ahead sets from item right con |
| 28 Feb 26 13:43:17 |
From: rprogers@seanet.com Qwen3-coder just pointed out that what I've described is actually "LALR(1) with context-sensitive look-aheads," also known by a couple other names. To get true LALR(1), you'd have to take the union of the FIRST(RCG(i,j)) over states j containing item i. But that seems silly since it's better and less code without doing the union :) --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
