This is an application that lets you post to multiple web services at once.
While you can use Multiposter from the REPL, it also has a convenient command line interface. To build a binary, simply run sbcl --eval '(asdf:make :multiposter)'.
The following services are supported:
On the command line you can simply run multiposter and it should show you a nice help text with all the available options and commands.
If you'd like to contribute another client to Multiposter, it's not too hard. Simply create a new client class with define-client, and ensure all the properties that should be persisted for it are returned from an initargs method. Then implement methods for the post, ready-p and setup functions.
If your service supports undoing/deleting a post, you should also create a result subclass and implement the undo method for it. Your post methods should then return a result instance on success, such that the post can be removed again later if desired.
For the setup function, make sure you implement the following logic: if &rest args are passed, reinitialise your client to use those initargs. Otherwise, if your client is not yet ready-p, perform an interactive setup using query to prompt the user for the necessary options.
