A noncanonical parser is able to suspend a reduction decision where its canonical counterpart would not be deterministic, explore the remaining input, perform ...

In this paper, we first survey the known methods of providing noncanonical extensions to LR parsers, then give a new class of grammars which provides bounded ...
The talk advocates the use of noncanonical parsers wherever deterministic parsers are needed: they preserve the linear time parsing and unambiguity properties, ...

An LALR parser is a software tool to process (parse) text into a very specific internal representation that other programs, such as compilers, can work with.
If multiple non-terminals are provided in start, the parser expression produces a list of parsing functions, one for each non-terminal in the same order.
We conclude by proposing a method for constructing compact. GPLR parsers from LALR(1) machines and identifying future directions for research in incremental, ...
