### What it is ASDF-System-Connections provides auto-loading of systems that only make sense when several other systems are loaded. If I'm lucky, an example will make this clear! [CL-Containers][] and [CL-Variates][] are separate systems and can therefore be loaded independently. If both of them are loaded, however, then it makes sense to also load code that uses CL-Variates to sample random elements from containers. Rather than requiring you to remember to load that extra system (and to load it only after both Cl-Containers and CL-Variates are loaded), ASDF-System-Connections lets you set things up so that loading happens automatically. Here is a simple example from [metabang-bind][]'s system definition: (asdf:defsystem-connection bind-and-metatilities :requires (metabang-bind metatilities-base) :perform (load-op :after (op c) (use-package (find-package :metabang-bind) (find-package :metatilities)))) The _requires_ clause specifies the other systems that must be loaded before this connection will be activated. The rest of the system definition is regular [ASDF][]. ASDF-System-connections will be loaded as soon as the systems they require are all loaded and they will only be loaded once. Before loading a system that uses a system connection, you should load ASDF-System- Connections in the usual manner: (asdf:oos 'asdf:load-op 'asdf-system-connections) ### Mailing Lists Nope. Sorry, there isn't one. You can, however, contact [Gary King][gwking-mail]. The best way to keep updated is to follow the metabang weblog: [unClog][] ### Where is it the current ASDF-System-Connections repository is on [github][github-asdf-System-Connections] and you can clone it using: git clone git://github.com/gwkkwg/asdf-System-Connections Its CLiki home is right [where][cliki-home] you'd expect. {anchor news} ### What is happening
