elm-package says version 0.17 just like all the binaries. So it is a
mystery why the auto-gen of elm-package.json is sticking in the wrong
versions for core. But I just edited the JSON by hand and am unblocked.
I'm writing a bridge card game in elm. First version in 0.16. I really
struggled with all the SIGNAL and foldp stuff. I was nervous about moving
to Cmd / Msg etc. But it proved easy and I find the new paradigm much
easier to grok intuitively. I based those changes on the Mario in 0.17
someone posted so it was easy.
One big chicken-and-egg problem I had with foldp was figuring out window
dimensions as I needed to draw my card table to fit the window at init
time, before any signals came in. I couldn't figure out how to do this
graceful so had to hack my old view function to check if the window was not
initialized yet.
It's easy and graceful in 0.17 via:
App.program
{ init = (initialModel, Task.perform (\_ -> DoNothing) WinResize
Window.size)
