Viddy
Viddy is an interactive terminal command monitor and watcher that executes shell commands at recurring intervals to track changes in output over time. It functions as a command execution history pager and output difference viewer, allowing users to monitor real-time state changes within a terminal interface.
The tool distinguishes itself by providing playback and history navigation capabilities, enabling users to move backward and forward through a recorded sequence of previous command outputs. It includes a dedicated output diff viewer that visually highlights text additions or removals between consecutive executions.
The system incorporates a keyboard-driven pager for inspecting long outputs through scrolling and text searching. It also features state management to pause and resume periodic execution and a configuration system for customizing keymappings and color schemes.
Features
- Interval Command Monitoring - Executes shell commands repeatedly at fixed intervals to provide real-time monitoring of state changes.
- State History Buffers - Implements a memory buffer that stores sequential command outputs to enable bidirectional navigation through history.
- Scheduled Command Execution - Executes specified shell commands on a recurring interval to monitor real-time state.
- Keyboard-Driven Interfaces - Provides a keyboard-driven interface for scrolling and navigating through extensive command outputs.
- Diff Viewers - Provides a visual interface to compare consecutive command executions and highlight text additions or removals.
- Interactive Terminal Watchers - Functions as an interactive replacement for the watch command with integrated playback, pausing, and history navigation.
- Terminal Pagers - Implements a scrollable pager view for inspecting long command outputs with keyboard navigation.
- Command History Navigation - Enables keyboard-driven traversal through a recorded sequence of previous command outputs.
- Output Difference Highlighting - Compares new command output with previous versions to visually highlight additions and removals.
- Execution History Pagers - Provides a terminal interface for scrolling through and navigating previous versions of command outputs.
- Terminal Output Analysis - Compares consecutive command results to visually identify differences and track changes over time.
- Diff Change Styling - Visually marks text additions and removals between consecutive command executions to highlight changes.
- Pause and Resume Controls - Allows users to pause and resume the periodic execution of shell commands without terminating the session.
- Text Pattern Search - Provides a text search interface to locate specific strings within the captured command output.
- Terminal Pagers - Uses a terminal pager to scroll and search through command results that exceed the screen size.
- Periodic Loop Executions - Manages the lifecycle of recurring command executions, allowing users to pause and resume them dynamically.
- Keymap Action Dispatchers - Maps keyboard shortcuts to internal application actions via a persistent configuration file.
- Infrastructure and Monitoring - Enhanced watch command.
