JSIL

JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime. Unlike other cross-compiler tools targeting JavaScript, JSIL produces readable, easy-to-debug JavaScript that resembles the code a developer might write by hand, while still maintaining the behavior and structure of the original .NET code.

For live demos and code samples, visit the website.

For help on getting started using JSILc, see the wiki.

JSIL is currently in partial maintenance mode (due to time constraints on the maintainer's part), but bug reports and questions are still actively responded to. Pull requests still welcome!

JSIL depends upon or is based on the following open source libraries:

• Mono.Cecil: MIT/X11 (thanks to Jb Evain)
• ICSharpCode.Decompiler: MIT/X11 (developed as part of ILSpy)
• Mono.Options: MIT/X11 (Jonathan Pryor & Federico Di Gregorio)
• printStackTrace: Public Domain (Eric Wendelin and others)
• XAPParse: Microsoft Public License/Ms-PL (Andy Patrick)

• S3TC DXT1 / DXT5 Texture Decompression Routines (Benjamin Dobell)

The Upstream folder also contains:

• Win32 build of the Spidermonkey command-line JavaScript shell. It is built from sources provided by the Mozilla project (http://www.mozilla.org/). This build is used for running JavaScript automated tests.
• A specific version of the NUnit.Framework assembly, used by the automated tests. This ensures that they compile correctly regardless of which version of NUnit you have installed.
• Win32 build of PNGQuant for optimizing PNG files. (Jef Poskanzer, Greg Roelofs)
• Mono ILASM for CIL tests execution

The following NuGet packages are used:

• Grunt
• Node
• NPM
• NUnit
• NUnit Test Adapter
• FSharp CodeDom
