Progress

Track the Progress of one or more Tasks (like downloading multiple files in parallel).

Sample Progress Tracking

A demonstration of all the capabilities can be found here: ../cmd/demo-progress

Track one or more Tasks at the same time
Support for both determinate (with Total) and indeterminate (without Total) trackers
Error tracking with MarkAsErrored() for failed tasks
ETA (Estimated Time of Arrival) calculation for each tracker
Speed calculation (items/bytes per second) with customizable formatters
Overall progress tracker that aggregates progress across all trackers

Dynamically add one or more Task Trackers while Render() is in progress
Sort trackers by Index (ascending/descending), Message, Percentage, or Value
- SortByIndex / SortByIndexDsc - Sort by explicit Index field, maintaining order regardless of completion status (done and active trackers are merged and sorted together)
- For other sorting methods, done and active trackers are sorted separately, with done trackers always rendered before active trackers
Tracker options
- AutoStopDisabled - Prevent auto-completion when value exceeds total
- DeferStart - Delay tracker start until manually triggered
- Index - Explicit ordering value for trackers (used with SortByIndex)
- RemoveOnCompletion - Hide tracker when done instead of showing completion

Choose to have the Writer auto-stop the Render when no more Trackers are in queue, or manually stop using Stop()
Redirect output to an io.Writer object (like os.StdOut)
Pinned messages that stay visible above all trackers
Log messages during rendering that appear temporarily
Automatic terminal width detection to prevent line wrapping
Flexible tracker positioning (left or right of message)
Configurable update frequency for smooth rendering
