# DevTools

A collection of developer tools to enhance your workflow. This package includes tools for generating commit messages, changelogs, and .gitignore files, all accessible from a single unified CLI: `devtools`.

## Installation

```bash
# Clone the repository
$ git clone https://github.com/S4NKALP/DevTools.git
$ cd devtools

# Install in editable mode
$ pipx install .

# Using Uv
$ uv tool install .
```

## Configuration

### API Keys

The tools use various APIs that require API keys. You can set these using the config command:

```bash
# Set AI provider API key (required for AI features)
# For OpenRouter
devtools config set OPENROUTER_API_KEY "your-openrouter-api-key"

# For OpenAI
devtools config set OPENAI_API_KEY "your-openai-api-key"

# For Google Gemini
devtools config set GOOGLE_API_KEY "your-google-api-key"

# For Anthropic Claude
devtools config set ANTHROPIC_API_KEY "your-anthropic-api-key"

# For Hugging Face
devtools config set HUGGINGFACE_API_KEY "your-huggingface-api-key"

# Set GitHub token (recommended for license generator)
devtools config set GITHUB_TOKEN "your-github-token"
```

Or set them in your environment:

```bash
# AI Provider API keys
export OPENROUTER_API_KEY="your-openrouter-api-key"
export OPENAI_API_KEY="your-openai-api-key"
export GOOGLE_API_KEY="your-google-api-key"
export ANTHROPIC_API_KEY="your-anthropic-api-key"
export HUGGINGFACE_API_KEY="your-huggingface-api-key"

# GitHub token for license generator
export GITHUB_TOKEN="your-github-token"
```

Or create a `.env` file in your project root:

```bash
OPENROUTER_API_KEY=your-openrouter-api-key
OPENAI_API_KEY=your-openai-api-key
GOOGLE_API_KEY=your-google-api-key
ANTHROPIC_API_KEY=your-anthropic-api-key
HUGGINGFACE_API_KEY=your-huggingface-api-key
GITHUB_TOKEN=your-github-token
```

### Managing Configuration

```bash
# Show all configuration
devtools config show

# Show specific value
devtools config show OPENROUTER_API_KEY

# Delete a value
devtools config delete OPENROUTER_API_KEY

# Clear all configuration
devtools config clear
```

Configuration files are stored in:

- `~/.devtools/config.yaml`

Example config.yaml:

```yaml
# API Keys
OPENROUTER_API_KEY:
OPENAI_API_KEY:
GOOGLE_API_KEY:
ANTHROPIC_API_KEY:
HUGGINGFACE_API_KEY:
GITHUB_TOKEN:

# AI Settings
provider: openrouter # or "openai", "gemini", "claude", "huggingface"
model: mistralai/mixtral-8x7b-instruct # model name for the selected provider
max_tokens: 1024
temperature: 0.7
output_format: text

# Commit Settings
conventional_commits: true
emoji: false

# Repository Settings
repositories: []
```

## Configuration via CLI

You can set up all configuration options for DevTools using the CLI. This is the recommended way to configure your `~/.devtools/config.yaml` file:

```bash
# Set AI provider (required for AI features)
devtools config set provider "openrouter"  # or "openai", "gemini", "claude", "huggingface"

# Set preferred AI model (optional, depends on provider)
# For OpenRouter
devtools config set model "mistralai/mixtral-8x7b-instruct"
# For OpenAI
devtools config set model "gpt-4-turbo-preview"
# For Gemini
devtools config set model "gemini-pro"
# For Claude
devtools config set model "claude-3-opus-20240229"
# For Hugging Face
devtools config set model "mistralai/Mixtral-8x7B-Instruct-v0.1"

# Set temperature for AI completions (optional, default is 0.7)
devtools config set temperature 0.7

# Set maximum tokens for AI completions (optional, default is 150)
devtools config set max_tokens 150

# Set conventional commit style (optional, default is true)
devtools config set conventional_commits true

# Enable or disable emojis in commit messages (optional, default is false)
devtools config set emoji false

# Set output format (optional, e.g., text or markdown)
devtools config set output_format text

# Set repositories list (optional, usually not needed)
devtools config set repositories "[]"
```

To view your current configuration:

```bash
devtools config show
```

To delete a config value:

```bash
devtools config delete output_format
```

To clear all config:

```bash
devtools config clear
```

All configuration is stored in `~/.devtools/config.yaml` and can be managed entirely through these commands. You do not need to manually edit the YAML file.

## Usage

All tools are available under the main `devtools` command:

```
devtools [COMMAND] [SUBCOMMAND] [OPTIONS]
```

### Commit Message Generator

Generate and apply commit messages, create changelogs, and manage configuration.

#### Generate Commit Message

```bash
devtools commit generate [OPTIONS]
```

**Options:**

- `--files, -f [FILE]...` Specific files to generate commit messages for
- `--repo, -r PATH` Repository path (default: current directory)
- `--commit, -c` Automatically commit changes
- `--push, -p` Push changes after commit
- `--conventional/--no-conventional` Use conventional commit format (default: True)
- `--no-stage` Skip automatic staging of changes
- `--sign` Sign commits with GPG
- `--temperature FLOAT` AI temperature (0.0-1.0)
 - `--emoji/--no-emoji` Include emoji prefixes (default: disabled)

Commit messages follow the conventional format (emojis optional):

When emojis are enabled, these prefixes are used:
- ✨ feat: New feature
- 🐛 fix: Bug fix
- 📚 docs: Documentation
- 💅 style: Formatting, missing semi colons, etc
- ♻️ refactor: Code refactoring
- ✅ test: Adding tests
- 🔧 chore: Maintenance

#### Changelog Generation

```bash
# Generate from git history
devtools commit changelog generate [OPTIONS]

# Generate interactively
devtools changelog generate [OPTIONS]

# Generate from a file
devtools changelog generate-from-file [OPTIONS]
```

**Options:**

- `--version, -v VERSION` Version number for the changelog entry (required)
- `--from-tag, -t TAG` Generate changelog from this tag
- `--days, -d N` Generate changelog from the last N days
- `--commits, -n N` Generate changelog from the last N commits
- `--output, -o FILE` Output file path (default: CHANGELOG.md)
- `--temperature FLOAT` AI temperature (0.0-1.0)
- `--input, -i FILE` Input file with changes (for file-based generation)

The changelog generator supports three modes:

1. Git history: Automatically generates changelog from commit history
2. Interactive: Enter changes manually with emoji prefixes
3. File-based: Generate from a file containing changes

Changes are grouped by type with emojis:

- ✨ Added
- 🔄 Changed
- 🐛 Fixed
- 🚀 Performance
- 📝 Documentation
- 🔧 Maintenance
- 🗑️ Removed
- 🔒 Security

#### Repository Status

```bash
devtools commit status
```

---

### Gitignore Generator

Generate .gitignore files for your project, either by auto-detecting project types or specifying technologies.

#### Auto-detect Project Types

```bash
devtools gitignore auto [OPTIONS]
```

**Options:**

- `--directory, -d DIR` Directory to scan (default: current directory)
- `--output, -o FILE` Output file path (default: .gitignore)

#### Generate for Specific Technologies

```bash
devtools gitignore generate python django vscode [OPTIONS]
```

**Options:**

- `--output, -o FILE` Output file path (default: .gitignore)

The generator uses the gitignore.io API to fetch templates. No API key is required.

---

### License Generator

Generate LICENSE files for your project using templates from GitHub's license API.

```bash
# List available licenses
devtools license list

# Generate a license
devtools license generate [OPTIONS]
```

**Options:**

- `--type, -t TYPE` Type of license to generate (e.g., mit, apache-2.0, gpl-3.0)
- `--author, -a NAME` Name of the author/copyright holder
- `--year, -y YEAR` Year for the copyright notice (defaults to current year)
- `--output, -o FILE` Output file path (default: LICENSE)

Example:

```bash
# List available licenses
devtools license list

# Interactive mode
devtools license generate

# With all options specified
devtools license generate --type mit --author "John Doe" --year 2024 --output LICENSE
```

The license generator uses GitHub's license API to fetch templates. For optimal performance:

1. Set up a GitHub token:
   ```bash
   devtools config set GITHUB_TOKEN "your-github-token"
   ```
   This increases your API rate limit from 60 to 5,000 requests per hour.

2. If no token is set, the tool will use a fallback list of common licenses.

If an invalid license type is provided, the tool will display a list of available licenses.

### Hooks Manager

Manage Git hooks easily. Install lint/test hooks for `pre-commit` and `pre-push`.

```bash
# Install both pre-commit and pre-push hooks in current repo
devtools hooks install

# Install only pre-commit
devtools hooks install --pre-commit --no-pre-push

# Install only pre-push
devtools hooks install --no-pre-commit --pre-push

# Uninstall hooks
devtools hooks uninstall           # both
devtools hooks uninstall --pre-commit --no-pre-push

# Use your own script templates
devtools hooks install \
  --pre-commit-template ./scripts/hooks/my-pre-commit.sh \
  --pre-push-template ./scripts/hooks/my-pre-push.sh

# List hooks present in the repository
devtools hooks list
```

The hooks auto-detect your ecosystem and run sensible defaults:

- Node.js: `npm run lint --if-present` then `eslint` or `prettier --check`; tests via `npm test`/`pnpm test`/`yarn test`
- Python: `ruff .` or fallback to `black --check .`; tests via `pytest -q`
- Rust: `cargo fmt --check`; tests via `cargo test`
- Go: `gofmt -l` (fail if unformatted), `go vet`; tests via `go test ./...`
- Java: Gradle `check`/`test` or Maven `verify -DskipTests=true`/`test`
- If `.pre-commit-config.yaml` is present, `pre-commit run --all-files` is used for pre-commit, and `pre-commit run --hook-stage push --all-files` for pre-push.

You can customize hooks by editing files in `.git/hooks/` after installation.
Alternatively, pass `--pre-commit-template` and/or `--pre-push-template` to install from your own script files. The files will be copied into `.git/hooks/` and made executable.

Note: If a hook already exists, DevTools creates a timestamped backup in `.git/hooks/` with the `.bak` suffix before overwriting, e.g., `pre-commit.20250101123000.bak`.

Auto-fix behavior (pre-commit):

- If initial checks fail, DevTools attempts to auto-fix issues by running `scripts/format.py` and `scripts/lintfix.py` if those files exist in your repo.
- Any changes made are automatically staged (`git add -A`), and checks are re-run. The commit will fail only if the re-run still fails.
- You can run these scripts manually as well:

```bash
python3 scripts/format.py
python3 scripts/lintfix.py
```
