Why do you use `(flip andThen)`?

Why do you use (flip andThen)?

TLDR; To use it with the pipe (|>) operator.

The actual andThen problem

Here is the signature for Task.andThen:

import Task exposing (andThen)
View decodeJson.elm
module Test where
import Text (asText)
import Array (Array, get)
import Json.Decode (..)
import Maybe (..)
type alias Foo =
{ foo : String
, bar : Bar

Convert a List of objects into a Dict (≈ Map) using an object's property as key, in a type safe way with ELM

import Dict
-- The transformation function
listToDict : (a -> comparable) -> [a] -> Dict.Dict comparable a
listToDict getKey values = Dict.fromList (map (\v -> (getKey v, v)) values)

sbt-we plugin workflow
View stylus-shell.js

We'll take the stylus plugin as an exemple.

Making it work with Node.js

To make our plugin to work with node, we are going to use Christopher's js-transpiler. It allows to develop a shell script that will work independtly on both node and the jvm. You can call a shell script from the cli like this:

    node my-shell.js file.extension '{"flag":true}'

You can use this to debug your processor until it works!

Demo of wOOOt api
Todos =
# public properties
list: OOO.observableArray([])
# public methods
counter: OOO.computed ()->
@list.length + " remaining todos"
clear: ()->
@list.remove (_)-> _.done
You can’t perform that action at this time.
