JSで書かれたECMAScript RegExpパーサーの比較 | Memory ice cubes
OXCで正規表現パーサーを実装してるときに全部一通り読んでみて、みんな違ってみんな良いってなったので。 候補はこちらの3つ。 https://github.com/jviereck/regjsparser https://github.com/DmitrySoshnikov/regexp-tree https://github.com/eslint-community/regexpp かのAST Explorerでも、RegExp部門ではこの3つがリストにある。 AST explorer https://astexplorer.net/ 前提 ECMAScript本体だと、ESTreeというデファクトがあるけど、残念ながらRegExpにはない。 ESTreeでのRegExpの扱いはこんな感じで、ただの文字列でしかない。 interface RegExpLiteral <: Literal
Regenerator, AST, and ES6 at Facebook (Tech Talk by Ben Newman)
See the full post here: http://www.hakkalabs.co/articles/ecmascript-6-at-facebook Ben Newman (Engineer, Facebook) has spent many months creating Regenerator which brings support for ES6 style generators to your code. In this popular talk, Ben will talk about what led him to create Regenerator, show us what it can do today, and talk about where it's going in the future. This talk was presented at
Parsing in JavaScript: all the tools and libraries you can use
This is an article similar to a previous one we wrote: Parsing in Java, so the introduction is the same. Skip to chapter 3 if you have already read it. If you need to parse a language, or document, from JavaScript there are fundamentally three ways to solve the problem: use an existing library supporting that specific language: for example a library to parse XML building your own custom parser by
ESTree 互換っぽい AST を出力する JavaScript のパーサーまとめ
@babel/parser Babel で使われているパーサー。最新の JavaScript だけでなく、まだ ECMAScript に入っていないプロポーザルや TypeScript、Flow もオプションで対応している。また、AST は ESTree と一部互換性がないものを出力するが、estree プラグインを使うことで、ESTree 互換の AST を出力させることもできる。 Prettier のデフォルトパーサー。@babel/eslint-parserを使うことで ESLint のパーサーとしても使うことができる。 @typescript-eslint/typescript-estree @typescript-eslint/parser の内部で使われている TypeScript をパースするためのパーサー。 内部的には TypeScript Compiler API を使っ
Lezer
The Lezer Parser System The problem of parsing structured text has resisted one-size-fits all solutions for over 60 years. Lezer isn't such a solution either, but it is a very decent parser generator, especially well suited for use in code editors. Lezer (the Dutch word for reader, pronounced like “laser”) provides a parser generator that outputs JavaScript modules, which can be loaded to parse co
