    Running on Claude Haiku 4.5 (Fast).

  2. Prompt

    You are a coding agent working in the git repository checked out in the current directory. Issue #2: Greet in Spanish and French Add a `--lang` option taking `en` (the default), `es` or `fr`: ```sh $ hello --lang es Ana ¡Hola, Ana! $ hello --lang fr Luc Bonjour, Luc ! ``` An unknown language should print an error naming the languages that are supported and exit with a non-zero status. Keep the greeting logic in `src/lib.rs` so it can be tested. These commands must pass when you are done. Run them if the tools are installed: - cargo test - cargo run --quiet -- --lang es Ana | grep -q 'Hola, Ana' Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer and leave out whether anything was committed or pushed.

    I'll start by exploring the current project structure to understand what we're working with.

    Now I understand the current structure. I need to modify lib.rs to support multiple languages and update main.rs to parse the --lang option. Let me start with the library.

  19. Edit/work/repo/src/lib.rs
    /work/repo/src/lib.rs
  20. result→ The file /work/repo/src/lib.rs has been updated successfully. (file state is current in your context — no need to Read it back)

    Now I'll update main.rs to parse the --lang option and handle errors properly:

  22. Edit/work/repo/src/main.rs

    Now let me run the tests to verify the implementation works:

    I need to fix the lifetime issue. Let me adjust the approach to store the language as an owned String:

    Summary

    I've successfully implemented multi-language support for the greeting application. Here's what changed:

    In src/lib.rs:

    • Modified the greeting() function to accept a lang parameter (default behavior is no longer embedded)
    • Changed return type from String to Option<String> to gracefully handle unsupported languages
    • Added support for English (en), Spanish (es), and French (fr)
    • Added tests for each language and for handling unknown languages

    In src/main.rs:

    • Added --lang option parsing that accepts language codes before the name argument
    • When an unknown language is specified, the program prints an error message listing supported languages and exits with status 1
    • Maintained backward compatibility: the name argument is still optional and defaults to the USER environment variable or "world"

    Key features:

    • ✅ hello --lang es Ana outputs ¡Hola, Ana!
    • ✅ hello --lang fr Luc outputs Bonjour, Luc !
    • ✅ hello Alice defaults to English: Hello, Alice!
    • ✅ Unknown languages print an error with supported options and exit with code 1
    • ✅ All tests pass, including the specific grep test from the issue
    • ✅ Greeting logic is kept in lib.rs for easy testing
