Hi all
I’m looking into progress bar options for Julia. Many packages, during installation, show a rotating ◓ becoming a tick when finished. Anyone can help how to print out this dynamic symbol?
Thanks a lot!

Not the rotating symbol but [GitHub - timholy/ProgressMeter.jl: Progress meter for long-running computations](https://github.com/timholy/ProgressMeter.jl) offers a progress bar.

Looks like it is mixed in with the precompile monitoring logic, but the list of characters is easy to grab:

Thank you, it is very helpful.

A PR to support rotating “spinners” in ProgressMeter.jl is here: [add spinner option to ProgressUnknown by stevengj · Pull Request #206 · timholy/ProgressMeter.jl · GitHub](https://github.com/timholy/ProgressMeter.jl/pull/206)

With the latest version of ProgressMeter (1.7.1), you can now just pass `spinner=true` when creating a `ProgressUnknown` meter. For example:
```julia
prog = ProgressUnknown("Working hard:", spinner=true)
while true
ProgressMeter.next!(prog)
rand(1:2*10^8) == 1 && break
end
ProgressMeter.finish!(prog)
```

Another (somewhat silly) way to draw a spinner:
```julia
command = "
t=Threads.@async read(stdin, Char)
while !istaskdone(t)
for q=['◒','◐','◓','◑']
print(q)
sleep(0.1)
print('\b')
end
end
";
let
proc_input = Pipe();
proc = run(pipeline(`julia -e $command`, stdin = proc_input, stdout = stdout, stderr = stderr), wait = false)
sleep(2)
write(proc_input,'c') #Signal the spinner process to stop
while(process_running(proc))
sleep(0.1)
end
end
```
The spinner is drawn by shelling out to an external Julia process, which has its downsides, but it can update completely independently of the main process. I could never get `kill()` to work here, so the spinner process just runs until it reads something from its `stdin`.
