Syntax sugar and other goodies for working with xml-rpc.el
Using xml-rpc is prone to code like:
(setq myurl "http://hostname:port/path") (xml-rpc-method-call myurl 'method "arg") (xml-rpc-method-call myurl 'other-method "other-arg")
This library lets us instead write:
(xrc-defcaller service :url "http://hostname:port/path") (service 'method "arg") (service 'other-method "other-arg")
Sure that doesn't look much shorter but it adds up. The syntactical sugar makes a difference for exploratory programming, but could also provide benefits such as sanity checks on method names and arguments for XML-RPC services.
Append :checked-p t to the end of the xrc-defcaller line to have an error raised immediately by the library if a method is called that is not supported by the endpoint.
