GitHub - shobrook/wut: A terminal assistant for the hopelessly confused

Dec 20, 2024 - github.com
The article introduces "wut," a command-line interface tool designed to help users understand the output of their last terminal command. By typing `wut`, users can receive explanations for stack traces, error codes, incorrect commands, and log summaries. The tool supports integration with language models like OpenAI and Claude, requiring users to set the appropriate API keys in their environment. Additionally, it can work with local models via Ollama.

To use "wut," it must be run within a `tmux` or `screen` session to capture the last command's output. The article provides examples of how "wut" can clarify errors, such as explaining why a Git command failed. Future plans for "wut" include removing the `tmux` or `screen` requirement, adding a `--fix` option to execute suggested commands, integrating with Homebrew, and developing unit tests.

Key takeaways:

  • wut is a CLI tool that helps explain the output of your last command using an LLM, aiding in understanding stack traces, error codes, and more.
  • Installation requires setting up API keys for OpenAI or Claude, or using a local model with Ollama by configuring environment variables.
  • The tool must be used within a tmux or screen session to capture the last command's output, providing explanations or answering specific queries.
  • Future plans include removing the session requirement, adding a --fix option, integrating with Homebrew, and creating unit tests.
