I'm working on past Advent of Code puzzles to warm myself up for this year's and I wanted to copy a result to the clipboard so I could paste it into the AOC website.
But I can't see an easy way to do it
Am I missing something simple or is the facility missing?
I came up with this method
and then selecting the value in list block and using ctrl-C on it
but its a big sledgehammer for a little job 
you can use this block, but in order to copy a list, you need to do something like
wait until(call (JSFunction [data] [let res = null; navigator.clipboard.writeText(data.toString()).then(_ => { res = data; ).catch(err => {throw err;}); return () => res;] :: operators) with inputs [what you need to copy]:: control
we can't see the whole code.
Not the same code, but this one would work: (takes a parameter data) const d = typeof data === 'string' ? data : JSON.stringify(data, null, 2); navigator.clipboard.writeText(d); note that running multiple times doesn't guarantee the first one is done before the second runs.
The problem is that navigator.clipboard.writeText is asynchronous, and you need to wait for the returned promise to resolve before doing the next action.
There is a handy tool to streamline the process: Snap! Build Your Own Blocks
Just click reporter script with [Alt] pressed. For simple types, lists, and multidimensional tables clipboard will be filled with the text representation of the result.
I explicitly said that it's async, "running multiple times doesn't guarantee the first one is done before the second one runs"
The best solution would be js function blocks to be async/awaitable
