AngleSharp.Scripting

AngleSharp.Scripting extends the core AngleSharp library with some useful scripting capabilities. This repository contains multiple packages. All of them are quickly presented in this file.

Current status of this repository:

AngleSharp.Scripting.CSharp

The repository contains helpers for dynamic evaluation using the DLR. The dynamic helpers enable JavaScript-like programming, without any requirements on casting. Nevertheless, as in a JavaScript, you'll need to be sure that the instance you are dealing with really exposes the API you are using.

Additionally this library has eventually the goal of providing a very fancy way of integrating Roslyn, scriptcs or any other C# script engine. In HTML files that have been parsed with a configuration that uses WithCSharp, scripts can be provided in using the text/c-sharp type. Such scripts will then be transformed and evaluated by the provided C# script engine.

The transformation should set the this pointer to the IWindow instance. Additionally the DLR will be used. Finally it will be possible to also reference other libraries in the script. The script tag might be used to include external libraries via NuGet.

Status Highly experimental and most things are not implemented.

AngleSharp.Scripting.JavaScript

The repository contains DOM bindings for the Jint JavaScript engine. Jint is fully ECMAScript 5 compatible and provides the basis for evaluating JavaScripts in the context of the AngleSharp DOM representation.

The library comes with a service that exposes WithJavaScript to IConfiguration. This enables automatic evaluation of script elements that have a valid JavaScript type (or without any explicit type, since JavaScript is the default one). The DOM bindings are pre-generated and do not use reflection. Since Jint is interpreting JavaScript, the library can be consumed as a PCL. The downside is that the performance is definitely worse than any compiled JavaScript engine would deliver. For most scripts that should not be a big issue.

Status Currently leaving experimental stage and becoming alpha ready.
