pencilbox-dotnet

• PencilBox is a Virtual Machine for HTML canvas plotting.
• This is a PencilBox bytecodes compiler written in .NET core.

Environment

.NET Core >= 1.1

How to use

Example: basic plotting

PencilBox.DSL op = new PencilBox.DSL();
PencilBox.Compiler compiler = new PencilBox.Compiler();

compiler = Compiler()
compiler.compile(
  op.beginPath(),
  op.rect(0, 0, 50, 50),
  op.arc(25, 25, 25, 0, 1.5 * 3.14159265359),
  op.closePath(),
  op.strokeStyle("red"),
  op.stroke()
)
bytecodes = compiler.output() // We get list of bytecodes here

Example: fibonacci

PencilBox.DSL op = new PencilBox.DSL();
PencilBox.Compiler compiler = new PencilBox.Compiler();

var code = op.scope("fib",
    op.func("n")(
        op.ifElse(
        op.lt(op.get("n"), 2),
        op.get("n"),
        op.add(
            op.apply(op.get("fib"), op.sub(op.get("n"), 1)),
            op.apply(op.get("fib"), op.sub(op.get("n"), 2))))
    )
  )(
    op.print("dotnet fib pencilbox", op.apply(op.get("fib"), 30))
  );

compiler.compile(code);
var bytecodes = compiler.output() // We get list of bytecodes here

Using bytecodes

Once the bytecodes is generated, it should be passed to PencilBox runtime in browser to run the program. Please checkout the PencilBox runtime How to use
