WebApr 5, 2024 · 最近では PEG（Parser Expression Grammar）も知られるようになってきました。 PEGの特徴の一つは，構文ルールだけでなく字句ルールも同時に定義できることです。現在、主要なプログラミング言語のほとんどにPEGパーサージェネレータが存在します。中には抽象構文木（AST）まで生成してくれるものもあります。こうしたツール … WebParsing is a problem that is computationally difficult. There has been over fifty years of research on this subject, but there is still much to learn. Roughly speaking, there are four general algorithms to let a computer parse input: LL parsing. (Context-free, top-down parsing.) LR parsing. (Context-free, bottom-up parsing.) PEG + Packrat parsing.

WebA parser is usually composed of two parts: a lexer, also known as scanner or tokenizer, and the proper parser. Not all parsers adopt this two-steps schema: some parsers do not depend on a lexer. They are called scannerless parsers.
