In computer science, a parsing expression grammar (PEG) is a type of analytic formal grammar, i.e. it describes a formal language in terms of a set of...

LL parser is called an LL(k) parser if it uses k tokens of lookahead when parsing a sentence. A grammar is called an LL(k) grammar if an LL(k) parser can...

it takes parsing expression grammars (PEGs) as input rather than LL grammars. In 1970, Alexander Birman laid the groundwork for packrat parsing by introducing...

operator precedence parsers. An operator-precedence parser is a simple shift-reduce parser that is capable of parsing a subset of LR(1) grammars. More precisely...
