Sorry for the delay on this, but I updated the formatter before realizing the demo project wasn't on the right version to use the new {} syntax, so it'll be a little delayed while I update the demo project to the latest Phoenix.

@srcrip are you not able to usemix format --migrate to automatically convert to use the new syntax? maybe I can help out if you wish?

[srcrip]

it's all good, it should be fixed now. Sorry it took me a while! the problem was a combination of the formatter thing, but also the formatter broke some tests that cared about newlines in the html elsewhere that wasn't immediately obvious.

[srcrip]

actually, one more problem sorry

ok, for reference, in here I fixed this weird usage of body to reference the text of the toast where everywhere else I called it msg, but for some reason it still worked? It works either way. I have no idea why. I must be double-assigning msg to body somewhere else. That'd be something good to track down and remove.

Anyway I'm full sending this now, as it all seems to work for me.

@srcrip thanks for the effort. I have spotted one issue with the release: #46
