24 alternatives to Use Python docstrings as exception messages

The following exception @dataclass class PodBayDoorsStillClosed(DocumentedError): """ I’m sorry, {self.user_name}. I’m afraid I can’t do that. """ user_name: str when raised as raise PodBayDoorsStillClosed('Dave') will print PodBayDoorsStillClosed: I’m sorry, Dave. I’m afraid I can’t do that. Reduce the boilerplate, use more exception classes to better express the business logic, or invent your own use cases :) Can be tried out as: pip install documented which works for Python ⩾ 3.8.1.

    Stack Error is a pragmatic error handling library for Rust that provides helpful messages for debugging, and structured data for runtime error handling. Features: * Informative error messages: stack error messages and optionally add file/line context to your messages. This helps convey not just what went wrong, but also how it went wrong, making debugging faster. * Programmatic error handling: include optional error codes and URIs for robust runtime handling. * Library-Friendly: define custom error types easily while staying compatible with Rust’s error ecosystem. If designing good…

    A Simple Inbox for Your Exceptions and Odd Events▲10

    Hi HN, Our Slovenia-based team has worked on numerous projects over the years, and we kept running into the same challenge—handling rare exceptions, edge cases, and one-off manual workflows. Instead of rebuilding the same tooling every time, we decided to create a dedicated solution: Exceptions Inbox. It's a container for your exceptions, rare manual workflows, or events that don't have an obvious home. You can submit an exception with a single HTTP request and get notified when they are collected. Take a look: https://wt.tools/home/exceptions-inbox Let us know if you…

    OSS Python client for creating MCP capable agents in 6 lines of code▲5

    Hello HN, Pietro here! I've been really excited to see the recent buzz around MCP and all the cool things people are building with it. Though, the fact that you can use it only through desktop apps really seemed wrong and prevented me for trying most examples, so I wrote a simple client, then I wrapped into some class, and I ended up creating a python package that abstracts some of the async uglyness. You need: * one of those MCPconfig JSONs * 6 lines of code and you can have an agent use the MCP tools from python. The structure is simple: an MCP client creates and manages the connection and…
