A rundown of what's happened this week in the Elm community, and an exercise to
add a tab showing projects cards for the user.
We'll begin with links, covering: Elm 0.18 released, and upgrading made easy;
type bombs; ML in Erlang; a more featureful input field; forms made easier.
Might as well get the biggest link out of the way first:
Elm 0.18 Was Released!!!
The Perfect Bug Report
Evan's announcement post focuses on the new Debugger and how it makes life super
nice if you're trying to reproduce errors in your program. A few other notable
- Even better error messages! A few previously confusing cases have been
identified and made nicer.
- Less Syntax! This means that some things are going away. Specifically:
- Primes are out. You can expect them to be replaced by underscores in some
cases, and better naming in other cases.
List.range takes the place of interpolation, so no more
- Backticks are out. Now, the goal is to make things easily chainable with
pipe syntax. To that end,
andThen and other commonly-backticked functions
have had the order of their arguments swapped. In some cases, this involved
renaming the functions as well, for readability.
Html.App is gone, with
program and friends just moved to the
elm-lang/http had a few big ticket items (track progress, rate limit) added,
and it's been made easier for newcomers to use.
elm-lang/navigation no longer has a
Parser, so this will change how its
programs work a decent bit. I'll cover it later.

If you want to just trivially upgrade your elm app to 0.18, this tool is for
you. It should basically take care of everything.

Type Bombs in Elm
Kris Jenkins discusses a feature he thinks Elm should have, then points out that
Elm totally has this feature by way of a hack presently. I use it moderately
frequently, but if it didn't feel like a hack I might reach for it more often.

MLFE: ML Landing in the Erlang World
Not at all related to Elm, but rather ML on the Erlang VM. As this is a
longstanding goal of mine, I figured I'd take this soapbox to spread the
interest. I'm not yet using this but it's good news that it's advancing.

Elm Simple Form has been renamed to Elm Form, and has support for dynamic lists
of fields now as well.
[ h/t @etaque ]
This week we added a much more full-featured
View.Users.Show module. We've
implemented all but one of the tabs this week, so you won't be surprised to find
out that we'll implement that next. It's the projects tab! For now, you can
see it here:
We'll just use the projects from the projects model for now, so you'll want to
do the same trick we used for
API.fetchUsers for the projects on this route as
well, for now. Good luck!
