Gem provides animated spinner for UNIX shell and could be used with rake tasks and any console scripts. It basically wraps any code and show spinner until code isn't completed.
gem install shell-spinner
In Rails 3, add this to your Gemfile and run the
The main gem function
ShellSpinner accepts text string as first argument,
which is not required, but it's better to have it for pretty output.
And it accepts block of code. So spinner will be presented while block is running.
require 'shell-spinner' # With message ShellSpinner "Positive result" do Rake::Task["foo:bar"].invoke end # Spinner without message ShellSpinner do sleep 1 end # With exception ShellSpinner "Code with exception" do sleep 2 raise "Some exception" end
This code produces output similar to:
> Positive result... done > Code with exception... fail > <exception message and backtrace>
I can't show you a spinner there, but promise - it appears :)
To see an example of the code in action you can execute
bin/example from your terminal.
