Aider Config for Rust with Auto-formatting

Aider configuration file optimized for Rust projects with automatic code formatting and testing.

Configuration Details

This configuration enables efficient Rust development workflows with Aider by:

1. **Automatic Formatting**: Runs `cargo fmt --` after each code change to maintain consistent code style

2. **Automatic Testing**: Executes `cargo test` after modifications to catch regressions immediately

3. **Prompt Caching**: Enables caching for faster response times on repeated operations

4. **Minimal Shell Commands**: Disables shell command suggestions to keep focus on code changes

5. **Clean Git History**: Disables commit message author attribution for cleaner commits

Instructions

When using this Aider configuration:

1. **File Location**: Save this configuration as `.aider.conf.yml` in your project root directory

2. **Rust Formatting**:

- The `lint-cmd: cargo fmt --` setting runs Rust's formatter on all changes

- The `auto-lint: true` flag ensures formatting happens automatically after each edit

- Aider will format code before committing changes

3. **Automatic Testing**:

- The `test-cmd: cargo test` runs your full test suite

- The `auto-test: true` flag executes tests after code modifications

- Failed tests will be reported immediately so you can address issues

4. **Performance Optimization**:

- `cache-prompts: true` speeds up repeated operations by caching prompt responses

- Particularly useful for iterative development sessions

5. **Workflow Behavior**:

- `suggest-shell-commands: false` keeps Aider focused on code changes rather than suggesting shell commands

- `attribute-commit-message-author: false` creates cleaner git commit messages without attribution

Usage Example

Start Aider in your Rust project directory:

```bash

aider

```

With this configuration, Aider will:
