Aider Coder

Aider Coder

Terminal pair programming with Aider — an AI pair programmer that directly edits files in your local git repository.

Commands

Initialize a project

python3 aider_coder.py init [--dir /path/to/project]

Detects or creates a git repo, generates .aider.conf.yml with sensible defaults, and shows project status.

Run a coding task

python3 aider_coder.py code "Add error handling to the login function" --files src/auth.py src/utils.py
python3 aider_coder.py code "Refactor the database layer to use connection pooling" --files db/*.py
python3 aider_coder.py code "Fix the bug where null values crash the parser" --all

Runs aider with your natural language request against specified files. Use --files for specific files or --all to let aider auto-detect relevant files.

Show diffs

python3 aider_coder.py diff
python3 aider_coder.py diff --staged
python3 aider_coder.py diff --file src/auth.py

Shows git diff of changes made by aider (or any changes in the working tree).

Undo last aider commit

python3 aider_coder.py undo

Reverts the last commit made by aider (aider commits each change set). Useful when a change introduces regressions.

List / switch models

python3 aider_coder.py models
python3 aider_coder.py models --set gpt-4o
python3 aider_coder.py models --set claude-sonnet-4-20250514

Lists available models or switches the default model in .aider.conf.yml.

Run tests

python3 aider_coder.py test
python3 aider_coder.py test --cmd "pytest tests/ -x"
python3 aider_coder.py test --cmd "npm test"

Runs the project test suite. Auto-detects test runner (pytest, npm test, go test, cargo test, etc.) or uses a custom command.

Run linting

python3 aider_coder.py lint
python3 aider_coder.py lint --files src/auth.py
python3 aider_coder.py lint --fix

Runs linting on changed files. Auto-detects linter (ruff, flake8, eslint, golangci-lint, etc.) or uses project config.

Workflow

Quick coding session

1. Navigate to your project: cd /path/to/project
2. Init: python3 aider_coder.py init
3. Code: python3 aider_coder.py code "implement feature X" --files relevant.py
4. Review: python3 aider_coder.py diff
5. Test: python3 aider_coder.py test
6. If broken: python3 aider_coder.py undo

Model configuration

Aider supports many models. Set your API keys as environment variables:

• ANTHROPIC_API_KEY for Claude models
• OPENAI_API_KEY for GPT models
• OPENROUTER_API_KEY for OpenRouter models

Notes

• Aider makes real file edits and git commits — always review diffs before pushing
• Aider respects .gitignore and won't edit ignored files by default
• Use --no-auto-commits flag to stage changes without committing
• The .aider.conf.yml file persists your model and settings preferences
