abbrev Lake.ScriptFn : Type

The type of a Script's function. Similar to the main function's signature, except that its monad is also equipped with information about the Lake configuration.

Equations

• Lake.instInhabitedScript = { default := { name := default, fn := default, doc? := default } }

def Lake.Script.run (args : List String) (self : Lake.Script) : Lake.ScriptM Lake.ExitCode

Equations

• Lake.Script.run args self = self.fn args
