opts[:root] not be set after start server.

[zw963]

Hi, i saw following document in mastering roda.

:root sets the root path to the application in the file system. It is used for setting default paths for various parts of the application. It defaults to the current working directory of the process, so if our Roda application is being run from a different directory, we should definitely set this.

But, i test it with rackup, puma, or Procofile, all opts[:root] return nil.

in fact, i can't see any key name match root, following is my opts

{
          :default_headers => {
        "Content-Type" => "text/html; charset=UTF-8"

Thank you.

This is expected. If you don't provide a value for :root, the default value that is used when a root directory is needed is the current working directory of the process. However, Roda does not explicitly set the :root option (or any other options).

the default value that is used when a root directory is needed is the current working directory of the process.

Don't understand clear, sorry, so, if we want get this default value in a roda app, how to do that?

[jeremyevans]

Dir.pwd returns the current working directory of the process.
