Thanks,

that kind of pushed me into the right direction. So I test this module
by just requesting it. aperently that dont creates a .elc file.

So I use the function macro, that has somethnig to do with
bytecompiling, so doest it automaticly bytecompile that if its needed,
or did it ignore that I dont have let-alist loaded, because it is in the
function macro?

Normaly it should through a error if it cant find a macro/function that
is not availible right?

So I fixed it but would like to 100% understand what the problem was, to
avoid to make the same mistake again.

(defun kodi-remote-get (method params)
  "method to send get requests to the kodi instance"
  (let* ((request-data
          `(("id" . 0)
           ("jsonrpc" . "2.0")
           ("method" . ,method))))
    (if (equal params nil) ()
        (setq request-data
              (append request-data params
                      )))
    ;; (print request-data)
    (request
     (kodi-json-url)
     :data (json-encode request-data)
     :headers '(("Content-Type" . "application/json"))
     :success (function* (lambda (&key data &allow-other-keys)
                  (when data
                    (setq kodi-properties (let-alist (json-read-from-string 
data)
                                            .result))
                    ;; (print (aref (let-alist kodi-properties .episodedetails) 
0))
                    ;; (print data)
                    )))
     :error (function* (lambda (&key error-thrown &allow-other-keys&rest _)
                  (message "Got error: %S" error-thrown)))
     :complete (lambda (&rest _) (message "Finished!"))
     :parser 'buffer-string)))

that was the code I did not have
(require 'let-alist)

in the file?

I importet it with:

  (add-to-list 'load-path "~/.emacs.d/config/")
  (require 'kodi-remote)


Again thanks so far so I can release that code soon, but again I would
like to understand what the problem was. Do I have to have a
byte-compiled .elc file if I use the "function" macro

oh wait its the function* which is a alias to the cl-function macro in
cl-macs

so I need the cl library imported too. But well thats more relevant for
packaging I think, I think the main problem was that there just was no
.elc file?

Strange :) cant it just interpret the sourcefile when I require it on
emacs-start?
