About

An SQL-like language for querying the DOM. More info here.

Development

DOMQL is an interpereted language powered by the Sizzle selector engine.
Most SELECT queries can be directly compiled to a Sizzle query (see src/test.coffee).

DOMQL is written using the Jison parser generator.

Source Files Overview

  • dql.coffee is the main file. Responsible for initiating the parser and contains some utils (domReady, templates etc).
  • grammer.coffee is the language grammer file written in CoffeeScript's Jison DSL.
  • lexer.coffee is the language lexer.
  • nodes.coffee contains all the nodes for the syntax tree also responsible for compiling to sizzle / evaluating the code.
  • test.coffee the test suite ran by index.html.

Getting the Code

git clone git@github.com:amasad/DOMQL.git  

Dependencies

  • NodeJS for the development environment.
  • Browserify for Node requires to work in the browser.
  • express for development server.
  • uglify-js for minifying build file.
  • Jison for creating the parser.

You only need to install NodeJS. All the modules are checked in.
Note that browserify has been altered to work around a bug.

Running

Using CoffeeScript's Cakefile you could do the following:

  • cake buildParser : Builds the parser.
  • cake dev : Starts the development server at localhost:8080 and watches the grammer file for changes to rebuild the parser.
  • cake build : Builds and minifies to domql.min.js.

Tests

Run cake dev and navigate your browser to http://localhost:8080 then open your JavaScript console to see the test results.
