When your app launches in 3 seconds, your user may think twice before he runs it again. Optimizing the startup time involves a lot of investigation effort, covering areas from fast transport/delivery
JavaScript Parser Infrastructure for Code Quality Analysis
JavaScript Parser Infrastructure for Code Quality AnalysisAI-enhanced description This document introduces JavaScript Parser, an infrastructure for code quality analysis. It describes building blocks of a JavaScript engine including a parser, syntax tree, and virtual machine. It discusses producing a correct syntax tree and handling syntax errors. Code quality tools like linting, formatting, and c
James Shore: Lessons Learned: Lint and Javascript
Yesterday, I announced my new screencast series, Let's Code: Test-Driven Javascript. Today, I'm pleased to share an early screen test for the "Lessons Learned" channel. Each "Lessons Learned" episode provides a distilled look at a specific topic, such as automating Lint, testing a Node.js server, or automating cross-browser testing. The series also includes a "Live" channel: a live recording of a

README.markdownCode Painter Code Painter is a JavaScript beautifier that instead of asking you to manually specify the desired formatting style, can infer it from a code sample provided by you. This could, for instance, be a code snippet from the same project that your new code is supposed to be integrated with. It uses the excellent Esprima parser by Ariya Hidayat (thanks!). The name is inspired

JavaScript is very loose language. Closure Compiler helps us to keep quality of codes. jscc does: watch modification of your JS files (using watchdog and goog.require dependency), background compile & lint (using Closure Compiler and Closure Lint), visualize them with dinamic graph (using Highcharts and Flask). Dependencies Closure Linter growlnotify Watchdog Closure Library Closure Compiler Flask
JavaScript syntax tree visualization with Esprima · ariya.io
JavaScript syntax tree visualization with Esprima Apr 4, 2012 2 min read #code #esprima #javascript #parser One little feature I added to Esprima parser demo was syntax tree visualization (using YUI TreeView). While it is already possible to see the JSON version of the parsed AST, often a much more visual representation improves the syntax analysis workflow. It is also more educational. An example
UglifyJSの--defineと--define-from-moduleが便利すぎる - スコトプリゴニエフスク通信
JavaScriptのコードの中にアプリの設定を定数として埋め込みたいことってありますよね。例えば、このFacebook Mobileのドキュメントにあるログインの例を借りると、 window.fbAsyncInit = function() { FB.init({ appId: FB_APP_ID, status: true, cookie: true, xfbml: true, oauth: true }); FB.Event.subscribe('auth.authResponseChange', function(response) { if (__DEBUG__) { console.log("Got auth.authResponseChange event"); console.log(response); } // Do something }); }; のように、あるメソ
How to write JS code generator - 枕を欹てて聴く
esprimaに入りました. 次のversionからesprima.generateで利用可能です. Issue 89 - esprima - Code generator: convert AST to source code - ECMAScript parsing infrastructure for multipurpose analysis - Google Project Hosting JSのpretty printerを作りました. ECMAScriptのparserとしてesprimaを使っていて, 自作のcode generatorがASTから綺麗なJSをprintします. で, 現在はesprima code baseに持って行こうとしています. 将来的にesprimaで使えるようになる予定なので, 使いたい!! という方はお待ちください. operator prec
