Project DescriptionA compiler/minifier for JavaScript, built on Google Closure Compiler and YUI Compressor. It provides a .NET component for integration and a windows UI, allowing compilation of multiple source files in to one single file.
Overview
UI Compiler .NET provides a user interface and a .NET programming API to the most basic functionality of Google Closure Compiler and YUI Compressor.
UI Compiler .NET lets you merge multiple JavaScript files into one single, minified file. This approach will make your web page load and perform faster. The compiler will report errors and warnings. Since UI Compiler .NET has a core component, prividing an API, you can use it in your own applications or build scripts.
UI Compiler .NET can work directly with the Java application of Google Closure Compiler locally on your computer, or with its REST API. This means that you can use the REST API if you don't want to install Java on your computer or the local service (requires Java 6) if you want to compile/minify without having to access to the Internet. Note that the REST API cannot handle more than about 400 Kb input data.
Prerequisites
If you want to work locally with Gooble Closure Compiler, Java 6 or higher is required on any machine running _UI Compiler .NET.
UI Compiler .NET is built on .NET Framework 3.5.
Screenshot
Two files, with a total size of 18798 bytes are compiled into a single, minified file with a size of 6016 bytes.
Code example
The following code snippet shows how you can call UI Compiler .NET from your code. A more detailed specification of the API is included in the installation package.
using Interfleet.SE.UICompiler.Core;
// Create an agent factory, using the local compiler (a java component)
var agentFactory = CompileAgentFactory.CreateAgentFactory(CompileType.ClosureCompilerLocal);
// Build up arguments
var args = agentFactory.CreateArguments();
// Multiple files can be added, full filepaths are expected
args.Files.Add("c:\inputfile.js");
// full path of the compiled file
args.CompiledFileName = "c:\output.js";
args.CompileOption = "SIMPLE_OPTIMIZATIONS"
var closureCompilerAgent = agentFactory.CreateCompilerAgent(args);
// Compile
var result = closureCompilerAgent.Compile();
Output example
Input:
// -- function for determining how far horizontally the browser is scrolled
function scrollX() {
// A shortcut, in case we´re using Internet Explorer 6 in Strict Mode
var de = document.documentElement;
// If the pageXOffset of the browser is available, use that
return self.pageXOffset ||
// Otherwise, try to get the scroll left off of the root node
( de && de.scrollLeft ) ||
// Finally, try to get the scroll left off of the body element
document.body.scrollLeft;
}
Output:
function scrollX(){var a=document.documentElement;return self.pageXOffset||a&&a.scrollLeft||document.body.scrollLeft}
