Metaprogramming in C#.
Generate Partial method code at compile time on the fly.
Sample shows how to generate code for scenario given below
new JSAsm().Create();
partial class JSAsm
{
[JSMethod]
public partial void Create();
}Traversing Syntax Tree to generate compile time injectable code
// using the context, get a list of syntax trees in the users compilation
var syntaxTrees = context.Compilation.SyntaxTrees.Where(t => t.GetText().ToString().Contains("[JSMethod"));
sourceBuilder.AppendLine(@"using System;");
// add the filepath of each tree to the class we're building
foreach (SyntaxTree tree in syntaxTrees)
{
var v=tree.GetRoot().DescendantNodes().OfType<ClassDeclarationSyntax>().ToList();
}
