Hello, I want to change an atom only when another atom changes value, ho wdo I do that? For example, I have a value
(let [button-disabled? (r/atom true)])(let [email-button-disabled? (r/atom true)
number-button-disabled? (r/atom true)])it looks like those are not normal Clojure atoms but atoms from reagent library. if that is the case then look at reactions provided by reagent https://github.com/reagent-project/reagent/blob/master/doc/ManagingState.md#reactions
also there is #C0620C0C8 channel
Add-watch will work too I believe! But reactions are nice of course
Hello y’all, thanks for the amazing help last time! I’ve been banging my head against a sort problem regarding a vector of maps and maybe someone is able to point me into the right direction. I have following structure:
[{:score 22/111, :size 2}
{:score 8/113, :size 3}
{:score 200/221, :size 19}
{:score 8/113, :size 6}
{:score 2/3, :size 20}
{:score 1N, :size 3}
{:score 0, :size 2}]descending and by size ascending like this:
[{:score 1N, :size 3}
{:score 200/221, :size 19}
{:score 2/3, :size 20}
{:score 22/111, :size 2}
{:score 8/113, :size 3}
{:score 8/113, :size 6}
{:score 0, :size 2}]sort-by, group-by and min/max-key functions, but I wasn’t able to find the correct way to combine these for the desired result.
I’m grateful for any help and/or push in the right direction 🙂(->> data
