Write a Statement Parser in JavaScript - HTML Goodies.
Parser - JavaScript is fed into a Parser, which generates an Abstract Syntax Tree Interpreter - Abstract Syntax Tree is the input for the V8 Ignition Interpreter, which generates the ByteCode Compiler - The Turbofan Compiler of the V8 Engine takes in the ByteCode and generates machine code.
A Parse.Relation behaves similar to an array of Parse.Object for querying purposes, so any query you can do on an array of objects, you can do on a Parse.Relation. Data Types So far we’ve used values with type String, Number, and Parse.Object.
TL;DR; We have a lightweight, battle-tested, CSS parser and utility library written in JavaScript. It’s open source; Go and grab it here. We recently put forth a huge effort to build a cutting edge web designer for web forms. The project took 6 months to complete. The team was cross.
The ANTLR website has a JavaScript grammar already defined so we will take that grammar, get ANTLR to create a parser, and then use that parser to parse some JavaScript code. The following guide is based on using ANTLRWorks 1.4.2, which includes ANTLR 3.3, and the CSharp3 code generator version 3.3.1.
But it has some brilliant stuff in it that is well worth consideration. We will build a parser that can process Simplified JavaScript. We will write the parser in Simplified JavaScript. Simplified JavaScript is just the good stuff, including: Functions as first class objects. Functions in Simplified JavaScript are lambdas with lexical scoping.
If you insist on doing this, you should probably try to find lexer and parser generators somebody else has written for you to build upon, such as Peg.js (this is not a recommendation, just a pointer). Then you can build parsers on top of those mec.
The JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string. An optional reviver function can be provided to perform a transformation on the resulting object before it is returned.
