摘要

LL(1) grammars have the conceptual and practical advantage that they allow the compiler writer to view the grammar as a program; this allows a more natural positioning of semantic actions and a simple attribute mechanism. Resulting parsers can be constructed that do fully automatic error recovery, which allows the compiler writer to ignore totally the issue of syntax errors. Measurement shows that such parsers can be reasonably efficient.
