Emacs

A year ago, u/vsavchenko announced https://www.reddit.com/r/emacs/comments/wemj1z/writing_emacs_dynamic_modules_in_swift. I had been meaning to try it out for some time. Finally had the chance and it's really neat!

For example, most of the sharing logic from the experiment in the screen grab is below:

try env.defun(
  "macos-module--share",
  with: """
    Share files in ARG1.

    ARG1 must be a vector (not a list) of file paths.
    """
) { (env: Environment, files: [String]) in
  let urls = files.map { URL(fileURLWithPath: $0) }

  let picker = NSSharingServicePicker(items: urls)
  guard let view = NSApp.mainWindow?.contentView else {
    return
  }

  let x = try env.funcall("macos--emacs-point-x") as Int
  let y = try env.funcall("macos--emacs-point-y") as Int

  let rect = NSRect(
    x: x + 15, y: Int(view.bounds.height) - y + 15, width: 1, height: 1
  )
  picker.show(relativeTo: rect, of: view, preferredEdge: .maxY)

  return
}
