tramp related execution

[spiderbit]

I have following problem:

I use request to send a json message to a webserver in my lan. I have set that to a Shortcut (F6)
Normaly that works just fine, but if I am in a Eshell window that is connected to another pc over ssh or in a open file that is on another pc accessed through tramp, it just refuses to work.

It looks to me that it tries to execute the curl program then on that pc or something like that?

Is there a way to overwrite the executable url to lets say /~ or /tmp or something like that?

to be more precise I am the author or the package:
https://github.com/spiderbit/kodi-remote.el

which is using request.el to send the json messages to kodi.

And I bound kodi-remote-music to F6:

(global-set-key (kbd "<f6>") 'kodi-remote-music)

I ran into the same issue. Actually the Tramp support has some quirks:

• curl backend is chosen even if it is not installed remotely: executable-find is evaluated locally to set the request-backend
• Tramp support is not consistent: url-retrieve backend doesn't have Tramp support

You might just bind default-directory to enforce execution of curl on your local machine:

(let ((default-directory nil))
  (request "http://amazon-1d35745cb.fritz.box:8080"
	   :success (cl-function
		     (lambda (&key data &allow-other-keys)
		       (message "OK")))))

@spiderbit @juergenhoetzel does #82 fix your issue?

I'm afraid not. #82: is about invalid use of internal tramp functions. This issue is about different
behavior when using request on remote hosts: curl is executed on the remote host (contrary to the url-retrieve backend).

I will check it out.

Thanks for taking care of this nice Emacs package 👍

IMO this issue can be closed, because Tramp support for curl is intended and there is no way to implement tramp support using the url-retrieve backend.

thanks @juergenhoetzel -- sorry for the slow response. Closing this now!
