Elm range syntax
Update: Elm’s list range syntax has been removed as of version 0.18. The replacement is
List.range 1 2, which is if nothing else more searchable.
I recently stumbled around for more than a few moments searching for a canonical way to generate a range of numbers in Elm. I finally found a working example by searching for ”haskell range syntax“.
> [1..2] [1,2] : List number
Elm doesn’t appear to support the more advanced variants such as
[1,3..20], but this definitely covers 95% of my use cases.
This is actually documented under the Lists section of the syntax docs, but there aren’t any useful words for a search to match on. Hopefully this post will save a few minutes for a few people.
