Vandelay

Description

This library is an expriement with a module system with import/export.

Plugins are used to resolve paths, load files, resolve imports and transform source code.

Vandelay::Compiler#compile returns a hash of Vandelay::ResourceInfo which can be marshaled, and later unmarshaled into Vandelay::Runtime to run the same code later without having to transform everything again.

Inspired by ES-modules and Rollup.

Usage

Export

class Foo
  def hello
    puts "hello"
  end
end

Export = Foo

This class can be imported like this:

Foo = import("./foo.rb")

Multiple exports

module Export
  class Foo
  end

  class Bar
  end

  BAZ = "baz"
end

and can be imported like this:

MyModule = import("module.rb")
MyModule::Foo

Notes

It's not possible to use Sorbet in these modules.

It might be possible to generate RBS-files for each module using parlour.

import would have to be overloaded for each module, and each imported path must be mapped to an id, so that the RBI-generator can resolve the exports for that module.

However, this approach would require saving a module after changing imports to regenerate the RBI. It would be awesome if there was a way to get Sorbet to run a method that could resolve imports while editing, but I don't think there is.
