GitHub - hughsk/ast-pipeline: Seamlessly pipe between text transform streams and AST transforms
Seamlessly pipe between text transform streams and AST transforms. Say, for example, you have a source transform API similar to browserify's: each file goes through a series of transforms streams, the output of one becoming the input of the next. Recently an increasing number of transform streams have appeared that operate on plain old parseable JavaScript, generally using the following pattern: v

Falafel, Source Rewriting, and a Magicial Assert
A couple of weeks ago, I wrote about how to do some basic static analysis of Javascript source code using Esprima. This post is a follow up where I demonstrate how to write a program to transforms Javascript source code using an Esprima-based library - falafel. Hello, Falafel Falafel is an AST traversal library like estraverse. If you've read my previous article, this is familiar territory. Instea
Fun with Esprima and Static Analysis
Writing programs to do static analysis on Javascript is easier now than ever, thanks to Esprima - the Javascript parser library. In this post, I'll demonstrate how to use Esprima to do something fairly simple - detect accidentally leaked global variables in a program. Accidentally leaked global variables happen when a value is assigned to an identifier without declaring the identifier as a variabl

GitHub - millermedeiros/rocambole: Recursively walk and transform EcmaScript AST
This module was heavily inspired by node-falafel and node-burrito but I needed more information than what is currently available on falafel (specially about tokens, empty lines and white spaces) and also needed to do the node traversing on the opposite order (start from leaf nodes). The amount of changes required to introduce the new features and the differences on the concept behind the tool just
tkbjsでJavaScript ASTについて発表してきました
オフラインJavaScript勉強会 – Online Study TokyoBouldering.js | DoorkeeperでJavaScript ASTについて発表してきました。 JavaScript AST Walker JavaScript ASTがどんなものかや、どのようなツールで使われてるか、ASTを編集するのにどういうライブラリがあるかなどについて書いてあります。 (中でかなり重たいものを読み込んでるのでロードが終わるまで適応に待ったほうがいいです) JS ASTを触る練習のためにQUnitのテストをJasmineに変換するreQUnitというものを書いていたましたが、 ASTをセレクタで選択したり、変更したりするのがもっと楽にできたりするともっとカジュアルにASTを触れるようになる気がします。 後、自己紹介もかねてここ最近のJSer.infoについても話しました。
JavaScript Syntax | Grasp - JavaScript structural search, replace, and refactor
A node can have three different types of attributes. An attribute containing another node, an attribute containing an array of other nodes, or an attribute containing a primitive value such as a boolean, string, or number. Use grasp --help syntax for an overview of the syntax, and grasp --help node-type (eg. grasp --help if) for more about information about a node type. Skip to statements, express
