Progressbar
This project is a thread-safe terminal progress bar and IO progress wrapper for Go applications. It provides a library for rendering updating progress indicators and activity spinners within a command-line interface to visualize task completion and data stream progress.
The library includes a stream-wrapping IO interceptor that automatically tracks and displays the volume of bytes processed during read or write operations. It also supports indeterminate activity spinners for processes where the total work volume is unknown.
Users can configure the visual appearance of the progress indicators through custom colors, themes, and descriptive text. The system handles the dynamic updating of task completion visualization as a process advances toward a defined limit.
Features
- CLI Process Visualizations - Provides visual indicators specifically designed for command-line interfaces to represent task completion and background activity.
- IO Progress Tracking - Wraps data streams to automatically detect and display the volume of bytes processed.
- Byte Transfer Tracking - Monitors the number of bytes transferred during read and write operations to estimate completion progress.
- IO Progress Wrappers - Provides a utility that wraps data streams to automatically track and display byte transfer progress.
- Go Application Monitoring - Enables real-time tracking of internal process progress within Go applications.
- Terminal Progress Indicators - Provides dynamic, overwritable terminal updates to visualize task completion and data stream progress.
- IO Stream Wrappers - Wraps standard IO interfaces to automatically intercept and track bytes processed for progress updates.
- Indeterminate Indicators - Implements indeterminate indicators via spinners to signal activity when the total work volume is unknown.
- Task Progress Bars - Renders a terminal-based progress bar that updates dynamically to visualize task completion.
- CLI Spinners - Provides character-based loading spinners for command-line interfaces when task duration is unknown.
- Terminal Progress Libraries - A dedicated library for rendering updating progress indicators and activity spinners in Go CLI applications.
- Mutexes and Locks - Employs mutual exclusion locks to ensure thread-safe updates of progress state across multiple goroutines.
- ANSI Escape Sequence Renderers - Implements terminal output control using ANSI escape sequences to rewrite progress bars in place.
- Progress Bar Styling - Allows customization of spinner, bar, and theme styles for terminal progress indicators.
- Command Line Interfaces - Thread-safe terminal progress bar.
- Command Line Tools - Terminal progress bar implementation.
- Console Interfaces - Listed in the “Console Interfaces” section of the Awesome Go awesome list.
- Console UI - Thread-safe progress bar management.
- Terminal User Interfaces - Thread-safe progress bar for terminal applications.
