View Source Credo.Execution.Task behaviour (Credo v1.6.4)
A Task is a step in a pipeline, which is given an Credo.Execution
struct and must return one as well.
Tasks in a pipeline are only called if they are not "halted" (see Credo.Execution.halt/2
).
It implements a call/1
or call/2
callback, which is called with the Credo.Execution
struct
as first parameter (and the Task's options as the second in case of call/2
).

Callbacks
Is called by the pipeline and contains the Task's actual code.
Works like call/1
, but receives the options, which are optional when registering the Task, as second argument.
Gets called if call
holds the execution via Credo.Execution.halt/1
or Credo.Execution.halt/2
.
Works like error/1
, but receives the options, which were given during pipeline registration, as second argument.

Specs
call(exec :: Credo.Execution.t()) :: Credo.Execution.t()
Is called by the pipeline and contains the Task's actual code.
defmodule FooTask do
use Credo.Execution.Task
def call(exec) do
IO.inspect(exec)
end
end
The call/1
functions receives an exec
struct and must return a (modified) Credo.Execution
.
Specs
call(exec :: Credo.Execution.t(), opts :: Keyword.t()) :: Credo.Execution.t()
Works like call/1
, but receives the options, which are optional when registering the Task, as second argument.
defmodule FooTask do
use Credo.Execution.Task
def call(exec, opts) do
IO.inspect(opts)
exec
end
end
Specs
error(exec :: Credo.Execution.t()) :: Credo.Execution.t()
Gets called if call
holds the execution via Credo.Execution.halt/1
or Credo.Execution.halt/2
.
Specs
error(exec :: Credo.Execution.t(), opts :: Keyword.t()) :: Credo.Execution.t()
Works like error/1
, but receives the options, which were given during pipeline registration, as second argument.
