Collision
Collision is a command-line interface error report formatter and developer debugging tool. It functions as a terminal UI component that converts raw application crash logs into stylized, readable error messages.
The tool focuses on application crash diagnostics and command-line error reporting to improve the developer experience. It transforms technical error reports and stack traces into a clean, human-readable format to simplify the process of identifying and fixing software bugs.
The project achieves this by intercepting standard error streams and using pattern-matching to parse raw log strings. It applies ANSI-based terminal styling and template-based formatting to the captured output, rendering the final reports through a process-wrapper execution model.
Features
- CLI Error Reporting - Creates readable and stylized error messages for command line tools to help users debug application crashes.
- Process Execution Wrappers - Wraps external command execution to monitor the process lifecycle and capture failure data.
- Stderr Interception - Intercepts the standard error stream to capture raw crash output for transformation into stylized reports.
- Terminal Error Formatting - Provides visual rendering of technical errors in the terminal using predefined templates for consistent reporting.
- Error Reporting - Functions as a system for capturing and presenting application errors in a stylized, readable format.
- Regular Expression-Based Parsing - Uses regular expression pattern matching to extract structured crash data from raw application log strings.
- Crash Reporters - Provides crash diagnostics by presenting technical error reports and stack traces in a clear, human-readable format.
- Error Reporting - Displays stylized and readable error messages when a command-line application crashes to facilitate debugging.
- CLI User Experience Tools - Enhances the CLI user experience by improving how application failures are communicated through formatted diagnostic output.
- Debugging Tools - Provides a utility to simplify the debugging process by presenting crash data in a clean format.
- Formatted Output Buffers - Buffers process output in memory to ensure formatted error messages are rendered without interlacing.
- ANSI Escape Sequence Renderers - Generates raw terminal control codes to apply colors and layout styles to crash reports for better visual hierarchy.
- Terminal UI Components - Implements a visual formatting layer as a terminal UI component for displaying system errors and stack traces.
