JavaScript ASTを始める最初の一歩
何かJavaScriptのソースコードを機械的にチェックするためのツールを作りたいという場合に、JavaScriptのASTというものを触る必要が出てくると思います。 この記事では、その取っ掛かりとなる案内を簡単にまとめたものです。 ASTとは AST(Abstract Syntax Tree)はコードをパースした抽象構文木のこと。 JavaScriptの場合はJavaScriptオブジェクト(JSON)として表現されます。 コード: { "range": [ 0, 10 ], "type": "Program", "body": [ { "range": [ 0, 10 ], "type": "VariableDeclaration", "declarations": [ { "range": [ 4, 9 ], "type": "VariableDeclarator", "id": {
Concrete Syntax in tree · Issue #41 · estree/estree
Your imagination can probably take it from there. There's a whole slew of complex ES6 syntax forms which implies a deep rabbit hole of nooks and crannies where we need to be able to preserve information (in some way) that our normal approach to AST doesn't currently preserve. Consider the tree structure for the arrow function expression, for example... how and where could we represent /*29*/ and /
Deprecating esprima-fb · Issue #111 · facebook/esprima · GitHub
At this point we're ready to start deprecating esprima-fb. We'll ship a "final" version soon with anything we have but otherwise we don't plan on integrating new JS features. Once that version is shipped, we won't be actively maintaining the project and probably won't ship bug fixes either. At Facebook we're in the process of switching our parsing and transforming to make use of Acorn and Babel. T

[2015-02] 最近のJavaScript AST標準化の動き
以前書いた記事からのどんな感じの動きがあったのかまとめたものです。 最近気になったJavaScript AST周りの動き | Web Scratch 前回の記事 2015年の1月前後の内容が中心です。 前回のに比べ、JavaScriptのエコシステムの根幹でもあるパーサやASTの仕様まわりについての動きが最近活発なので、その辺を中心にまとめています。 RReverser RReverserさんはここ最近のJavaScript ASTに関係するところならどこでもみかけると思うので紹介。 主にacornのコミッターでもありますが、後ほど出てくるESTreeやBabelなど色々なところで活動しています。 またasterというASTの効率的に処理できるツールチェインを出したりしています。 AST周りでよく見る人やパーサをいかにまとめてあります。 JavaScript AST Links. esto
Towards ECMAScript 6 with Esprima 2 · ariya.io
Towards ECMAScript 6 with Esprima 2 Feb 9, 2015 3 min read #es6 #esprima #javascript Little did I know that the start of my adventure with Esprima three years ago will result in something beyond my expectation. While the syntax tree format used by Esprima is not original (see SpiderMonkey Parser API), this de-facto format gains a lot of traction since it provokes a Cambrian explosion of composable
Esprima 2.0 Released | Official jQuery Blog
Last week, the jQuery Foundation announced our adoption of the Esprima project, the widely used JavaScript parser that powers many code analysis tools. Today we’re pleased to announce the release of version 2.0, now available on npm. Up until now, the official releases of Esprima have only parsed ECMAScript 5 standard syntax. However, the experimental “harmony” branch has been adding ECMAScript 20
