From .Net Developer to Elm. Part 1 – Elm with Sublime.

No Comments

Elm is a an amazing way to build web applications that guarantees no runtime exceptions and blazingly fast rendering.
This is a path -one of many possible- to start Elm development.

Step One – Get the Right Tools.
Sublime is my editor of choice. Amazingly fast and extensible.

First, a few general tweaks

  • Enable Go to Definition on Ctrl + Mouse
    Create a new file – “Default (Windows).sublime-mousemap” – in %appdata%\Sublime Text 3\Packages\User
    With the following content:
    [
    {
    “button”: “button1”,
    “count”: 1,
    “modifiers”: [“ctrl”],
    “press_command”: “drag_select”,
    “command”: “goto_definition”
    }
    ]

  • Add a shortcut for locating a file in the file tree sidebar.
    Go to Preferences -> Key Bindings-User and add:
    { “keys”: [“alt+shift+l”], “command”: “reveal_in_side_bar” }
  • Pick a different theme, if you’d like – soda-theme.
  • Install Sublime Package Control to enable easy package installation – Package Control

Now, some Elm-specific changes.

  • Install Elm Language Package
  • Install elm-oracle to enable autocompletions.
  • Install Highlight Build Errors from Sublime Package Control
  • Install elm-format to enable auto-formatting. Just download the zip and add the executable to the path to make it work.
    To enable automatic formatting on every save, go to Preferences -> Package Settings -> Elm Language Support -> User, and add this setting: “elm_format_on_save”: true

When you work with elm files, you can press Ctrl+B to build it. If there are any errors or warnings, they will show up in the console below and also get highlighted.

If you want to see the definition of a method, press Alt+Up while your cursor is on the method.
