I’m relatively new to Elixir but encountered some similar frustration with multi-line formatting at the beginning, though I’ve since gotten more used to it. I realized, however, that I was often overmatching in order to reduce line count at the expense of readability.
The standard I’ve started to stick to is to only match in the function head on the minimum amount necessary to make that function body applicable to the given arguments. Everything else can be destructured in the function body. This means more lines of code on average, but function heads become more readable and convey more information by highlighting the specific elements of arguments that they’re really matching on.
