# CMAI - AI-Powered Commit Message Normalizer

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![Python 3.10+](https://img.shields.io/badge/python-3.10+-blue.svg)](https://www.python.org/downloads/)

CMAI is a CLI tool that uses AI to transform informal commit descriptions into standardized, professional Git commit messages based on your staged changes.

## 🚀 Quick Start

### 1. Installation

Install via `uv` (recommended) or `pip`:

```bash
# Install with all providers support
uv tool install cmai[all-providers]
# OR
pip install cmai[all-providers]

# For specific providers only: cmai[openai], cmai[ollama], cmai[anthropic], etc.
```

### 2. Configuration

Create the configuration file at `~/.config/cmai/settings.env`:

```env
# --- Remote Provider Example (OpenAI, DeepSeek, Zai, etc.) ---
PROVIDER=openai
API_KEY=your_api_key_here
MODEL=gpt-4o-mini
# API_BASE=... (Optional: Only needed for non-standard endpoints)

# --- Anthropic (Claude) Provider Example ---
# PROVIDER=anthropic
# API_KEY=your_anthropic_api_key_here
# MODEL=claude-3-5-sonnet-20241022
# ENABLE_THINKING=true
# THINKING_BUDGET=1024

# --- Local Provider Example (Ollama) ---
# PROVIDER=ollama
# OLLAMA_HOST=http://localhost:11434
# MODEL=qwen2.5:7b

# --- Commit Specification Rules ---
COMMIT_SPEC=conventional
COMMIT_STRICT=true
# COMMIT_ALLOWED_TYPES=feat,fix,docs,chore
COMMIT_SCOPE_POLICY=optional
COMMIT_SUBJECT_MAX_LEN=72
COMMIT_HEADER_MAX_LEN=100
COMMIT_SUBJECT_CASE=lower
COMMIT_ALLOW_BANG=true

# --- Large Diff and Context Optimization ---
MAX_DIFF_LENGTH=8000
MAX_DIFF_FILE_LINES=50
MAX_DIFF_FILES_FOR_AI=30
ENABLE_SPLIT_SUGGESTION=true
SPLIT_CONFIDENCE_THRESHOLD=0.75
DIFF_SUMMARY_CONCURRENCY=5
RETRY_MAX_ATTEMPTS=5
RETRY_BASE_DELAY_SECONDS=2.0
RETRY_MAX_DELAY_SECONDS=30.0
```

**Supported Providers:** openai, bailian, deepseek, siliconflow, anthropic, claude, zai (智谱), ollama.

**Tip:** You can also set CMAI_API_KEY or ANTHROPIC_API_KEY as environment variables instead of putting them in the config file.

### 3. Usage

Stage your changes and run cmai:

```bash
git add .
cmai "fix a bug"
```

The tool will output a normalized message and prompt for action:

- [c]ommit: Execute git commit.
- [e]dit: Edit the message manually.
- [r]egenerate: Ask the model to regenerate. You can provide an optional additional prompt.
- [a]bort: Cancel.

When `COMMIT_STRICT=true`, non-compliant messages cannot be committed.
The CLI will show warnings and only allow `edit`, `regenerate`, or `abort` until the message passes validation.

For very large staged diffs, CMAI now falls back to per-file truncated diff previews instead of only file names.
When a staged diff exceeds `MAX_DIFF_LENGTH`, CMAI asks whether to generate file-level summaries or use only the staged file list for commit generation.
During file summarization, CMAI runs file summaries concurrently and shows a single `tqdm` progress bar instead of printing each file's summary.

When providers hit rate limits (for example `403 RPM limit exceeded` or `429`), CMAI automatically retries with exponential backoff.
If final commit generation still fails after retries, CMAI falls back to a local heuristic commit message instead of exiting immediately.

If a commit error occurs, an appropriate error message will be displayed and retained here. You can open a new terminal to fix these issues and then input 'c' to proceed with the commit.

## 🛠 CLI Options

```bash
cmai [MESSAGE] [OPTIONS]

Options:
  -c, --config TEXT    Path to a custom configuration file
  -r, --repo TEXT      Path to the git repository (default: current dir)
  -l, --language TEXT  Target language for the commit message (e.g., "Chinese")
```

## ✅ Commit Specs and Formatting Preferences

- `COMMIT_SPEC`: `conventional` or `angular`
- `COMMIT_STRICT`: if `true`, block commit until message is valid
- `COMMIT_ALLOWED_TYPES`: optional comma-separated override for allowed types
- `COMMIT_SCOPE_POLICY`: `optional`, `required`, or `forbid`
- `COMMIT_SUBJECT_MAX_LEN`: max subject length
- `COMMIT_HEADER_MAX_LEN`: max full header length
- `COMMIT_SUBJECT_CASE`: `lower`, `sentence`, or `any`
- `COMMIT_ALLOW_BANG`: whether `!` is allowed in header
- `MAX_DIFF_LENGTH`: max characters for raw staged diff context
- `MAX_DIFF_FILE_LINES`: per-file changed lines kept in truncated preview mode
- `MAX_DIFF_FILES_FOR_AI`: max files included in file-level AI summarization
- `ENABLE_SPLIT_SUGGESTION`: enable split-commit recommendation
- `SPLIT_CONFIDENCE_THRESHOLD`: minimum AI confidence to show split recommendation
- `DIFF_SUMMARY_CONCURRENCY`: concurrent file-summary requests
- `RETRY_MAX_ATTEMPTS`: max attempts when provider hits rate limit (runtime minimum: 5)
- `RETRY_BASE_DELAY_SECONDS`: initial backoff delay for rate-limit retry (runtime minimum: 2.0s)
- `RETRY_MAX_DELAY_SECONDS`: max backoff delay for rate-limit retry (runtime minimum: 30.0s)

## 🔁 Retry and Fallback Behavior

- CMAI retries only on likely rate-limit errors (such as `429`, `RPM limit`, `too many requests`, `limit exceeded`).
- Backoff uses exponential delays with an extra scale factor: `base * 2^(attempt-1) * 1.5`, capped by `RETRY_MAX_DELAY_SECONDS`.
- If retries are exhausted for final commit generation, CMAI builds a local commit message that still follows your configured commit rules.
