ProgressBar is a simple Ruby library for displaying progress of long-running tasks on the console. It is intended to be as simple to use as possible.
gem install progress_bar
require 'progress_bar'
bar = ProgressBar.new
100.times do
sleep 0.1
bar.increment!
end
Produces output like:
[####################################### ] [ 59.00%] [00:06]
Note: It may not be exactly like this. I might have changed the default meters between now and when I wrote this readme, and forgotten to update it.
Usually, the defaults should be fine, the only thing you'll need to tweak is the max.
bar = ProgressBar.new(1000)
If you want to process several things, and update less often, you can
pass a number to #increment!
bar.increment! 42
By default, ProgressBar will use all available meters (this will probably change). To select which meters you want, and in which order, pass them to the constructor:
bar = ProgressBar.new(100, :bar, :rate, :eta)
:bar-- The bar itself, fills empty space with "#"s. Ex:[### ].:counter-- Number of items complete, over the max. Ex:[ 20/100]:percentage-- Percentage of items in the maximum. Ex:[ 42%]:elapsed-- Time elapsed (since the ProgressBar was initialized. Ex:[00:42]:eta-- Estimated Time remaining. Given the rate that items are completed, a guess at how long the rest will take. Ex:[01:30]:rate-- The rate at which items are being completed. Ex:[ 42.42/s]
Run the tests to see examples of all the formats, with different values and maximums.
