Afterimages of the download progress bar

[kimikage]

Afterimages of the download progress bar may be visible.

This is probably due to the redirection. I.e., once the download progress reaches "100.0 %", the actual download restarts from "0.0 %".

	(total, now) -> begin
	bar.max = total
	bar.current = now
	show_progress(io, bar)

This bug seems to be old and can be traced back to at least Julia v1.6.7.

There's also an overprinting bug around this code somewhere #3581

[kimikage]

Fixing the number of characters in the percentage would solve this problem.
E.g., use "%5.1f %%"

Pkg.jl/src/MiniProgressBars.jl

Line 51 in 78bca42

@sprintf "%2.1f %%" perc

Alternatively, a measure to perform line clearing when the value of max changes from the last time would also be effective.

This is off-topic, but the comment below has not been updated and has multiple typos.

Pkg.jl/src/MiniProgressBars.jl

Lines 78 to 89 in 78bca42

	# Useful when writing a progress bar in the bottom
	# makes the bottom progress bar not flicker
	# prog = MiniProgressBar(...)
	# prog.end = n
	# for progress in 1:n
	# print_progree_bottom(io)
	# println("stuff")
	# prog.current = progress
	# showproress(io, prog)
	# end
	#
	function print_progress_bottom(io::IO)
