# module WebConsole::Helper

### Public Instance Methods

console(binding = nil) click to toggle source

Communicates with the middleware to render a console in a `binding`.

If `bidning` isn't explicitly given, Binding#of_caller will be used to get the binding of the previous frame. E.g. the one that invoked `console`.

Raises DoubleRenderError if a double `console` invocation per request is detected.

    # File lib/web_console/helper.rb, line 11
    def console(binding = nil)
      raise DoubleRenderError if request.env['web_console.binding']

      request.env['web_console.binding'] = binding || ::Kernel.binding.of_caller(1)

      # Make sure nothing is rendered from the view helper. Otherwise
      # you're gonna see unexpected #<Binding:0x007fee4302b078> in the
      # templates.
