lib-cli-exit-tools
CLI exit handling helpers: clean signals, exit codes, and error printing
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries no security vulnerabilities, and solves a real problem for CLI developers: portable signal handling and consistent exit codes across platforms. Use it whenever you wrap a Click command that needs to behave correctly in shell pipelines and CI/CD systems.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or newer.
- Low friction: pure Python wheel with a single runtime dependency (rich-click).
- Active maintenance with recent releases.

What it is and what it does
lib_cli_exit_tools wraps Click commands to handle platform-specific signal translation, exception-to-exit-code mapping, and error output formatting. It solves the problem of CLI applications behaving inconsistently across shells, CI/CD systems, and operating systems by automatically converting Python exceptions (FileNotFoundError, PermissionError, KeyboardInterrupt) into standard exit codes, translating SIGINT/SIGTERM/SIGBREAK into structured exceptions, and gracefully handling BrokenPipeError when output is piped to truncating tools.
The library is built on rich-click and provides two main entry points: run_cli() for wrapping a single command with signal handling and exit-code translation, and cli_session() as a context manager for centralised configuration and testing. It supports optional traceback display via --traceback, custom signal handlers, and subprocess stdout/stderr capture. Configuration is test-friendly and requires no boilerplate beyond wrapping your Click command.
Use it for
- Wrap a Click command to ensure it returns exit code 130 on Ctrl+C and 141 on broken pipe, matching shell conventions.
- Build a multi-command CLI that toggles full Rich-formatted tracebacks via --traceback without modifying command code.
- Handle SIGTERM gracefully in containerised applications by translating it to a deterministic exit code.
- Test error paths by raising exceptions and verifying the correct exit code is returned without manual bookkeeping.
- Pipe CLI output to head or other truncating tools without noisy tracebacks when BrokenPipeError occurs.
