## ✨ What is GIMS?

GIMS is a revolutionary Git CLI tool that uses AI to automatically generate meaningful commit messages from your code changes. Say goodbye to generic "update code" commits and hello to descriptive, professional commit messages that actually tell a story.

### 🎬 See It In Action

```bash
# Traditional Git workflow 😴
git add .
git commit -m "update stuff"  # 🤦‍♂️
git push

# GIMS workflow ⚡
g o  # AI analyzes changes, commits with perfect message, and pushes!
```

## 🌟 Features

### 🤖 **AI-Powered Commit Messages**
- OpenAI, Google Gemini, and Groq support with automatic provider selection
- Smart diff analysis that understands your code changes
- Handles large codebases with intelligent summarization and safe truncation
- Optional Conventional Commits formatting and optional commit body generation (`--conventional`, `--body`)

### ⚡ **Lightning Fast Workflow**
- One command commits: `g o` - analyze, commit, and push
- Smart suggestions: `g s` - get AI-generated messages copied to clipboard
- Local commits: `g l` - commit locally with AI messages
- Staged-only by default for suggestions for precise control (use `--all` to stage everything)

### 🧠 **Intelligent Code Analysis**
- Analyzes actual code changes, not just file names
- Understands context from function changes, imports, and logic
- Graceful fallbacks for extremely large changesets and offline use

### 🛠️ **Developer-Friendly**
- Numbered commit history with `g ls` / `g ll` and index-aware commands
- Smart branching: `g b 5` creates branch from commit #5
- Safe operations with confirmations and dry-run support
- JSON output for editor integrations
- Quality-of-life: `--amend`, `undo` command, and automatic upstream setup on push
- Manual commit command for custom messages: `g m "your message"`

## 🚀 Quick Start

### Installation

```bash
npm install -g gims
```

### Setup AI (Choose One)

**Option 1: OpenAI**
```bash
export OPENAI_API_KEY="your-api-key-here"
```

**Option 2: Google Gemini**
```bash
export GEMINI_API_KEY="your-api-key-here"
```

**Option 3: Groq**
```bash
export GROQ_API_KEY="your-api-key-here"
# Optional, if self-hosting/proxying
export GROQ_BASE_URL="https://api.groq.com/openai/v1"
```

GIMS auto-detects configured providers. If none are configured, it uses a local heuristic to generate sensible messages.

### Your First AI Commit

```bash
# Make some changes to your code
echo "console.log('Hello GIMS!');" > hello.js

# Let AI commit it for you
g o
# Output: Committed & pushed: "Add hello world console log"
```

- `--amend`: Amend the last commit instead of creating a new one
- `--set-upstream`: On push, set upstream if the current branch has none

## 💡 Real-World Examples

### 🔧 Bug Fix
```bash
# You fix a null pointer exception
g o
# AI generates: "Fix null pointer exception in user authentication"
```

### ✨ New Feature
```bash
# You add a search function
g o  
# AI generates: "Add search functionality with pagination support"
```

### 📚 Documentation
```bash
# You update README and add comments
g o
# AI generates: "Update documentation and add inline code comments"
```

### 🎨 Refactoring
```bash
# You clean up code structure
g o
# AI generates: "Refactor authentication module for better maintainability"
```

## 🔥 Pro Tips

### 🎯 Perfect Workflow
```bash
g p                 # Pull latest changes
# ... code your features ...
g s                 # Preview AI suggestion from staged changes
g s --all           # Or stage everything and suggest
g l                 # Commit locally first
# ... test your changes ...
g o --set-upstream  # Push with automatic upstream setup on first push
```

### 🧠 Smart Branching
```bash
g ls                # See numbered history
g b 5 hotfix        # Branch from commit #5
g l                 # Make changes and commit
g checkout main && g pull  # Back to main
```

### 🛡️ Safe Experimentation
```bash
g l                 # Commit your experiment
# ... code breaks something ...
g r 1 --soft --yes  # Soft reset to previous commit (confirmed)
# ... or ...
g u --yes           # Undo last commit (soft)
```

## ⚙️ Configuration

### Environment Variables

| Variable | Purpose |
|----------|---------|
| `OPENAI_API_KEY` | OpenAI API access |
| `GEMINI_API_KEY` | Google Gemini API access |
| `GROQ_API_KEY` | Groq API access (OpenAI-compatible) |
| `GROQ_BASE_URL` | Groq API base URL (optional) |
| `GIMS_PROVIDER` | Default provider: `auto` | `openai` | `gemini` | `groq` | `none` |
| `GIMS_MODEL` | Default model identifier for provider |
| `GIMS_CONVENTIONAL` | `1` to enable Conventional Commits by default |
| `GIMS_COPY` | `0` to disable clipboard copying in `g s` by default |

### .gimsrc (optional)

Place a `.gimsrc` JSON file in your repo root or home directory to set defaults:

```json
{
  "provider": "auto",
  "model": "gpt-4o-mini",
  "conventional": true,
  "copy": true
}
```

### Smart Fallbacks

GIMS handles edge cases gracefully:

- 🔄 Large diffs: Automatically switches to summary or status view
- ✂️ Massive text: Truncates safely with informative context
- 🛜 No API key: Uses a local heuristic that summarizes your changes
- ⚠️ API failures: Clear errors and local fallback so you keep moving
- 🔒 Privacy-first: Only sends diffs when you explicitly run AI features
