SlashPress

Running any task any task that you want to start immediately from the comfort of your chat app. It’s great for providing instant summaries, triggering actions like backups, clearing/preloading caches of optimisation plugins, updating copies of remote data.

Your code can respond with anything you need, from a simple OK to a full tabulated response using Markdown:

|Order stat|Count|
|:---|---:|
|New orders today|27|
|Orders to fulfil|8|
|Unpaid orders|2|

A simple example is probably best:

            ->addHelp('uncache', 'Site content not looking quite right? Use `uncache` to clear the out the generated pages.');
    }
