The System API provides system-level functions for interacting with the SilverBullet environment.

<!--#lua spacelua.renderApiDocumentation("system") -->

Returns the running SilverBullet version.

## system.invokeCommand

`system.invokeCommand(name, args?)`

> **Deprecated:** Use editor.invokeCommand instead.

Deprecated alias for system.invokeFunction.

## system.listCommands
