  • install dependencies found in elm-package.json
  • compile X.elm, and all modules it depends on
  • write concatenated output to elm.js

• elm make X.elm --output=x.js

  • write concatenated output to x.js

Laszlo's JSON parsing proposal

The following functions should be available in Elm's standard library:

module Json where

parse : String -> Maybe JsonValue
getProp : String -> JsonValue -> Maybe JsonValue
toString : JsonValue -> Maybe String
toInt : JsonValue -> Maybe Int

Elm Style Guide

Purpose

The goal of the style guide is foremost to promote consistency and reuse of pattern from other languages in order to improve readability and make Elm easier for beginners. This includes moving Elm away from Haskell’s indentation style and even making some parts look closer to JavaScript. These decisions are intentional.

We would like Elm to look friendly and familiar to users of any language — especially JavaScript — so they can discover Elm’s powerful features without being overwhelmed. This does not intend to weaken or discourage any features of Elm, but instead to make them more accessible.

A secondary goal of the style guide is to encourage short diffs when changes are made. This makes changes more clear, and helps when multiple people are collaborating.
