clevergit 0.1.0

A CleverGit-like Git client tool with high-level abstractions

Project Documentation (CleverGit - Git Client, Python Implementation)

Quick Start

CleverGit provides two ways to interact with your Git repositories:

🖥️ Graphical User Interface (GUI)

Launch the GUI application for an intuitive, visual Git experience:

sgg
# or
python -m clevergit.ui.main

Features:

• Point-and-click repository management
• Visual file status display
• Branch management with drag-and-drop
• Commit history viewer
• Dialog-based operations
• Enhanced Diff Viewer - Professional, SmartGit-inspired code difference presentation
  • Softer color scheme for reduced eye strain
  • Word-level highlighting to spot exact changes
  • Improved visual spacing and separation
  • Side-by-side and unified views
• Command Palette - Quick search and command execution (Ctrl+P)
  • Search files, commits, and branches with fuzzy matching
  • Execute commands without navigating menus
  • Keyboard-driven workflow

👉 For detailed GUI documentation, see GUI_USAGE.md

💻 Command Line Interface (CLI)

Use powerful command-line commands for scriptable Git operations:

# View repository status
sg status

# Commit all changes
sg commit all -m "feat: add new feature"

# View commit history
sg log --oneline

# Manage branches
sg branch list
sg branch new feature/auth
sg branch switch main

Features:

• Fast, efficient terminal-based workflow
• Scriptable operations
• Batch processing support
• Integration with other tools

🐍 Python API

Use CleverGit programmatically in your Python scripts:

from clevergit import Repo

# Open repository
repo = Repo.open(".")

# Check status
status = repo.status()
print(f"Modified files: {len(status.modified)}")

# Create commit
repo.commit_all("fix: resolve issue")

# Branch operations
repo.create_branch("feature/new")
repo.checkout("feature/new")

📦 Installation

# Clone the repository
git clone https://github.com/petertzy/CleverGit.git
cd CleverGit

# Install with all features
pip install -e .

# Verify installation
sgg --version  # GUI version check
sg --version   # CLI version check

1. Project Background & Goals

This project aims to develop an advanced Git client tool CleverGit using Python, with focus on:

• Provide more user-friendly, higher-level Git operation abstractions
• Lower the learning curve for daily Git usage (especially complex commands)
• Support CLI-first, GUI-extensible architecture design

Target users:

• Developers familiar with Git basics but don't want to memorize commands frequently
• Users who want to operate Git in Python within scripts / toolchains

---

2. Design Principles

1. High-level semantics, not command concatenation Example:

   • repo.commit_all("fix login bug")
   • Instead of git commit -am "..."

2. Readability first Class names and method names should express "user intent" rather than Git details

3. Modular & Extensible

   • Decouple CLI / GUI / API
   • Can add TUI / Web UI later

4. Failure is explainable

   • Convert Git errors to "human-readable" exception messages

---

3. Technology Stack

• Python >= 3.10

• Git calling methods:

  • Preferred: GitPython
  • Fallback: subprocess (for scenarios GitPython doesn't support)

• CLI framework:

  • typer (recommended, type-friendly)

• GUI (future):

  • PySide6 or Tkinter

---

4. Core Feature Planning

4.1 Repository Management

• Open / Initialize repository
• Detect repository status
• Current branch, HEAD status

✔ Is it a Git repository
✔ Are there uncommitted changes
✔ Is it behind / ahead of remote branch

---

4.2 Status View

• Modified files
• Untracked files
• Staged files
• Conflicted files

Support:

• Group by file type
• Output as structured objects for UI use

---

4.3 Commit

• Commit all changes
• Selective commit (specific files)
• Auto-generate commit message (optional)
• Pre-commit checks (lint / test hooks)

---

4.4 Branch Management

• List branches (local / remote)
• Create / Delete / Rename branches
• Switch branches
• Display branch relationships (simple DAG)

---

4.5 Merge & Rebase (High-level Wrapper)

• Safe merge (detect conflicts)
• Interactive rebase workflow (step-by-step)
• Conflict file list + hints

---

4.6 Remote Repository Operations

• fetch / pull / push
• Show commits to be pushed / pulled
• force push risk warning

---

4.7 History (Log)

• Concise log view (like git log --oneline --graph)
• Filter by author / time / branch
• Single commit details

---

6. Core Object Design Example

Repo (Core Entry Point)

repo = Repo.open(".")

repo.status()
repo.commit_all("fix: login bug")
repo.create_branch("feature/auth")
repo.checkout("feature/auth")

Design goals:

• One Repo object = One Git repository
• Most features start from here

---

7. CLI Design Example

sg status
sg commit -m "fix bug"
sg branch new feature/auth
sg branch switch main
sg log --oneline

CLI principles:

• Short commands
• Don't require users to understand Git detail parameters

---

8. Error Handling Strategy

• Git raw errors → Custom exceptions
• CLI layer catches exceptions → User-friendly hints

Example:

❌ Current branch has uncommitted changes, cannot switch branches
Suggestions:
- Commit changes
- Or use sg stash

---

9. Future Expansion Directions

• GUI (graphical interface)

• AI assistance:

  • Auto-generate commit messages
  • Conflict resolution suggestions

• Plugin system (hooks)

• Git Flow / Trunk Based workflow support

---

10. One-Sentence Project Summary

Wrap Git's "intent layer" in Python, make Git usable like objects, not remembered like incantations.
