Clojurians Log v2

If I am understanding my bug right then I think I've been caught out by this before. That a single signal to a subscription is passed as a value, multiple signals are passed as a vector. Most of the time I am doing single signals and I get used to the idea they are values, then forget when I have multiple signals and get confused. If so, I might prefer that signals always be passed as a vector, even of 1 element, but I suspect that would break too much now.

They can also be passed as a map.

And nothing prevents you from wrapping even a single signal in a vector. It's all very simple - the shape of what you return from the signal function is preserved, that's it. A single value becomes a single value, a vector becomes a vector, a map becomes a map.

I realise now I wasn't clear, I'm taking about using the sugared :<- [:signal] syntax

if you use one you get a value, if you use more than one you get a vector of values

Ah, right, I see.

I feel you, made the same mistake with :<- many times! Same with forgetting to skip (`_`) the event ID when destructuring. Now all those things are second nature

Regarding _ - I just always add the trim-v interceptor to my event handlers. :)

I sometimes consider that, but then some other part of my brain decides that typing _ is shorter. 😅 What I probably should is write a wrapper around reg-event-*... I wonder if you can do the same for reg-sub to have single :<- return a vector?

> What I probably should is write a wrapper around reg-event-* That's exactly what I did initially. And then I started using kee-frame that already has that functionality. Regarding reg-sub - you would have to copy and alter the whole implementation of re-frame.subs/reg-sub.
