ForgeBox Enterprise
Progress Bar
When writing a Task that needs to iterate some predefined amount of work that might take some time, you can now tap into the Progress Bars in CommandBox easily for your own purposes.
There are two different progress bars in CommandBox. One specifically for downloading files, and a generic one.
Progressable Downloader
Here is how you can download a file in a Task Runner and have a progress bar animation that contains all the usual data such as download speed and file size. The progressable downloader will automatically take any HTTP proxy settings into account.

Generic Progress Bar
You can also use a generic progress bar for any purpose. It is up to you to update the progress bar with the current percentage. If you are inside of an Interactive Job, the progress bar will automatically show at the bottom of the job output.
