Link time. This week: drive a browser with Elm; find a function by its type
signature; write friendlier code; stalk a developer; Curry-Howard.
elm-webdriver is a library for
controlling the browser using Elm and Selenium.

elm-search is like Hoogle for Elm.
Search for functions by their types. A good example:
List (Generator a) -> Generator a.

Writing Friendly Elm Code is a nice article on what it means to write code that's nice for other engineers.

Evan's GitHub activity is a good way
to keep up with what might be coming. Or a way to stalk him. Either way.
The Curry-Howard Correspondence - If you enjoyed Philip Wadler's Propositions as Types talk, this is a more in-depth discussion of the basis of it. It's the fundamental reason I prefer FP these days.
This week we implemented a variety of
elm-mdl components, seeing Layout, List,
Card, Menu, and Textfield. The text field in the chat interface is a little sad
looking, as it doesn't use a Material component, and the content of the messages
is a bit lackluster as well.
For this week's exercise:
- Switch the user input box to use Material.Textfield.
- Make the layout's header look more appropriate. Here's the example of how the elm-mdl demo does it.
- Implement the message box as a list of messages.
- Add badges to connected channels showing the count of unread messages.
- Bring in evancz/elm-markdown and
render the text of the messages using it, for richer messaging.
- Make the chat card have a specified height so that it isn't growing as new
messages come in.
