$ show crocuda/pipelight
Pipelight is a Rust-based CLI tool for defining and running automation pipelines. It allows users to create pipelines using TOML, YAML, HCL, or TypeScript configurations, trigger them via git hooks or file system changes, and monitor their execution. The architecture follows a modular design with separate crates for CLI parsing, workflow execution, configuration casting, process management, and utilities. Key features include process detachment for background execution, output capture for post-execution inspection, git hook integration, and file watching capabilities. The project demonstrates strong engineering practices with comprehensive error handling, cross-platform considerations, and thoughtful UX design for terminal interactions.
The LLM identified 2 files worth highlighting for reuse:
A standalone process management library that provides a clean API for executing, monitoring, and controlling Unix processes. It supports background/detached execution, orphan processes (not killed when parent dies), and file-based output capture for later inspection. The crate demonstrates sophisticated handling of Unix process complexities with a builder-pattern API and comprehensive test coverage. It has zero internal dependencies on other project crates, making it highly extractable to other projects needing process management capabilities.
A utility module for handling Unix signals (particularly SIGINT/SIGTERM) and restoring terminal state to prevent leaving the terminal in a corrupted state after interruption. It uses signal_hook to set up signal handlers that restore terminal attributes when the application receives termination signals. This solves a common problem in CLI applications that use libraries altering terminal state (like for password prompts). The module is self-contained with minimal dependencies (console, signal_hook) and could be extracted to any CLI application needing robust signal handling.
