Pb
pb is a Go progress bar library and terminal UI component used to track and display the completion status of long-running tasks. It functions as an IO progress tracker by wrapping reader and writer operations to automatically update visual indicators as data flows through a system.
The library provides capabilities for rendering progress bars, completion percentages, and processing speeds within a console interface. It includes a system for customizing the visual layout, metadata templates, and color schemes of these status indicators.
The project covers IO stream monitoring and terminal-based UI design to provide real-time feedback during command line tool execution.
Features
- Terminal Progress Indicators - Renders dynamic, overwritable terminal updates showing completion percentage and processing speed for long-running tasks.
- Console UI - Provides tools for building and customizing visual status indicators and layouts within a console interface.
- IO Progress Tracking - Automatically detects and displays byte volumes processed during streaming IO to update progress bars.
- IO Progress Wrappers - Acts as a wrapper for reader and writer operations that automatically drives progress bar updates.
- IO Stream Wrappers - Provides wrappers that intercept IO read and write operations to track byte throughput in real time.
- Terminal Progress Bar Animations - Renders animated progress bars in the terminal to provide visual feedback for long-running tasks.
- Progress Rendering Libraries - Provides a comprehensive library for rendering visual progress bars and processing speeds in Go applications.
- Visual Feedback Components - Enables Go-based command line tools to provide visual feedback on long-running process status.
- ANSI Escape Sequence Formatting - Implements terminal escape sequences to refresh specific console lines and prevent screen flickering.
- Progress Bar Appearance Customizers - Allows customization of progress bar colors, spinners, and layout to match application styling.
- State Redraw Loops - Uses a state-driven redraw loop to periodically update terminal display based on real-time processing metrics.
- Terminal - Provides a template system for customizing the visual arrangement and metadata of progress indicators.
- Terminal UI Components - Implements a reusable terminal UI component to track and display the completion status of tasks.
- Command Line Tools - Console progress bar library.
