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": {
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

README.md Note: All source code in this repository is under the Unlicense. Proposal for SpiderMonkey AST representation for import and export statements The current AST format is both inconsistent and complicated. Esprima and Acorn have two different syntax trees for the same thing, and that currently heavily hinders inter-op between the two. Since the module syntax is stabilized, but I can tell t

Grasp - JavaScript structural search, replace, and refactor
Search, replace, and refactor your JavaScript code based on its structure rather than its text Grasp is a command line utility that allows you to search and replace your JavaScript code - but unlike programs such as grep or sed, it searches the structure behind your code (the abstract syntax tree), rather than simply the text you've written - this allows you to: Search your code with unparalleled
