Is there any way to leverage the pipe operator to access properties of an object after a sequence of operations?
I’m trying to do a sequence of operations followed by accessing a property in the final map but I can’t get it to work while making it look great
Here’s what I have:
hd(hd(ctg).tier_group.tiers_in_tier_group).tier.tier_pills
|> Enum.at(pill_ix)
|> &(&1.pill_id)
ElixirLS autocorrects this to
hd(hd(ctg).tier_group.tiers_in_tier_group).tier.tier_pills
|> Enum.at(pill_ix)
|> (& &1.pill_id)
and that does not work, it throws the following error:
(ArgumentError) cannot pipe Enum.at(
hd(hd(ctg).tier_group.tiers_in_tier_group).tier.tier_pills,
pill_ix
) into & &1.pill_id, can only pipe into local calls foo(), remote calls Foo.bar() or anonymous function calls foo.()
This makes me think it’s not possible, but there’s no harm in asking because it still feels like something with a trivial solution. The alternative would be doing this:
(hd(hd(ctg).tier_group.tiers_in_tier_group).tier.tier_pills
|> Enum.at(pill_ix)).pill_id
but this way makes me have to add an extra parenthesis to the front, which is a bit ugly in my opinion because in the case I have to do it several times it will accumulate a lot of parenthesis in the front, plus I’ll have to go back and forth adding them.
Any insights into this? Thanks!
