A module system and library for writing safe, maintainable Bash scripts with strict mode support.
bash-modules is a module system and library for Bash that provides reusable components like logging, argument parsing, and error handling. It helps developers write safer, more maintainable Bash scripts by enforcing strict mode and offering modular, well-tested utilities.
System administrators and developers who write Bash scripts for Linux environments and need robust error handling, logging, and argument parsing in their scripts.
It offers a standardized way to write Bash scripts with strict mode compliance, reducing common pitfalls and providing production-ready modules for logging and argument parsing out of the box.
Useful modules for bash
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides debug, info, warn, error, and todo logging functions with colorized output, enhancing script readability and debugging, as shown in the showcase images.
Enables declarative definition of command-line arguments with validation, help text generation, and support for required/optional flags, simplifying complex argument handling in scripts.
Full support for unofficial Bash strict mode (set -ue) ensures safer scripting by catching errors early, as demonstrated in the strict mode showcase.
Offers chain-of-errors reporting for debugging and panic mode with stack traces for immediate failure, aiding in error diagnosis and management.
The project has only a few core modules, and the TODO list admits the need for a repository for extra modules and cooperation with other Bash projects, indicating an immature ecosystem.
LGPL2+ license may hinder integration into non-GPL projects, as the README explicitly warns against copy-pasting code into non-GPL projects.
Error handling in subshells requires additional boilerplate code, such as extra panic handlers, which can be error-prone and less intuitive for developers.
