QUESTION
I am trying to upgrade Elm 0.18 to 0.19 and got stuck on a final step, where I can't figure out how to rewrite Elm 0.18 code to Elm 0.19. One issue I had was that the package mgold/elm-date-format": "1.5.0 <= v < 2.0.0
, which was one of the dependencies of the project, was not upgrded yet to support Elm 0.19 so I decided to replace it with ryannhg/date-format. I've also read in the migration docs that Time
and Date
moved to elm/time but I can't figure out how to rewrite the code below. I have no idea about Elm whatsoever so please go easy on me, I was just tasked to upgrade Elm from 0.18 to 0.19 in my project. I am trying to learn it, though.
Here's the code I have right now which does not work after upgrading to 0.19 plus the full stacktrace. I used the automated Elm upgrade tool for upgrading Elm

function,
You'll need to handle a result rather than a Maybe, and the total size of your compiled package will go up as this uses parsing libraries rather than using javascript's native data parser

I'm currently writing a web-based vocabulary trainer in Elm. This requires sorting a list of words by a custom comparator.
The type I want to sort is:

Answered 2017-Jan-08 at 18:46A more Elm-ish way of doing this kind of things is compositionally, thanks to the |>
operator.
The elm-ordering library provides the primitives that you need to do this kind of things, especially the Ordering.byField
and Ordering.breakTiesWith
functions.
As for the dates, my advice would be to use Date.toTime
(the resulting values are comparable).
Bonus: full implementation of your ordering function available for testing here: https://runelm.io/c/xoz. You can see it's much simpler and more readable than yours...
