Decision gist · record as of 2026-08-14
Yes, if you need simple, templated exception formatting with no dependencies. The package is stable, permissively licensed, and has low install friction. However, maintenance is dormant—no updates since 2023-09-17—so it is best suited for projects that do not require ongoing support or new features.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later.
- Low friction install with no runtime dependencies.
- Maintenance is dormant—last release was 2023-09-17 with no commits since—but the package is stable.

What it is and what it does
msgfy is a lightweight utility that transforms Python Exception instances into formatted text strings suitable for logging, display, or debugging. It provides two main functions: to_error_message() for standard error output and to_debug_message() for detailed debug context. Both accept optional format templates using keywords like {exception}, {file_name}, {line_no}, {func_name}, and {error_msg} to customize the output layout.
The package has no external dependencies and supports Python 3.7 through 3.11 on CPython and PyPy. It is useful when you need consistent, readable exception formatting across a codebase without building custom exception handlers. The library is stable but dormant—last updated 2023-09-17 with no recent maintenance activity.
Use it for
- Format exceptions for structured logging systems that require consistent message templates.
- Generate user-friendly error messages from exceptions while hiding internal stack details.
- Build debug output that includes file, line, and function context extracted from exception metadata.
- Standardize exception-to-string conversion across a codebase without duplicating formatting logic.
