hmm - Git Safety Wrapper

A safety wrapper for git push that prevents accidental pushes to origin without a branch name.

What does it do?

Have you ever typed git push origin and immediately regretted it? hmm adds a safety net by requiring 3 explicit confirmations before allowing a push to origin without a branch name.

Before hmm:

$ git push origin
# Oops... pushed to the wrong branch or with unintended behavior

After hmm:

$ git push origin
  DANGER: You are pushing to ORIGIN without a branch!
Type 'yes' to confirm [1/3]: yes
  WARNING: This may overwrite or break things on origin!
Type 'yes' to confirm [2/3]: yes
  FINAL CHECK: Do you really want to do this?
Type 'yes' to confirm [3/3]: no
Push cancelled.

Installation

Method 1: NPM/NPX (Recommended for Node.js users)

# Install globally
npm install -g hmm-git-safety

# Or use npx without installing
npx hmm-git-safety install

Method 2: Python/Pip (Recommended for Python users)

# Install via pip
pip install hmm-git-safety

# Run the installer
hmm install

Method 3: Homebrew (macOS)

# Add the tap (when published)
brew tap yourusername/hmm
brew install hmm

# Or install directly
brew install hmm.rb

Method 4: Direct Shell Script (Universal)

# Download and run installer
curl -fsSL https://raw.githubusercontent.com/yourusername/hmm/main/install.sh | bash

# Or manually
git clone https://github.com/yourusername/hmm.git
cd hmm
chmod +x install.sh
./install.sh

Method 5: GUI Installer (All Platforms)

Download and run the GUI installer:

# Requires Python 3 with tkinter
python3 gui_installer.py

The GUI provides a user-friendly interface for:

• Installing hmm
• Uninstalling hmm
• Checking installation status
• Viewing installation logs

Usage

Once installed, hmm works automatically. Just use git as normal:

# Safe - specifies branch
git push origin main
git push origin feature-branch

# Dangerous - will trigger 3 confirmations
git push origin

Management Commands

# Check installation status
hmm status

# Uninstall hmm
hmm uninstall

# Get help
hmm help

How it Works

hmm adds a bash/zsh function to your shell configuration file (.zshrc, .bashrc, or .profile) that wraps the git command. When you try to run git push origin without a branch name, it intercepts the command and asks for confirmation three times before proceeding.

The wrapper is lightweight and doesn't affect any other git commands.

Supported Platforms

• macOS (zsh, bash)
• Linux (bash, zsh)
• Windows (via WSL or Git Bash)

Uninstallation

# Using the command
hmm uninstall

# Or using the package manager you used to install
npm uninstall -g hmm-git-safety
pip uninstall hmm-git-safety

# Or using the uninstall script
./uninstall.sh

# Or manually remove the "hmm git safety wrapper" block from your shell config

Configuration Files

hmm automatically detects your shell and modifies the appropriate config file:

• zsh: ~/.zshrc
• bash: ~/.bashrc
• other: ~/.profile

Why "hmm"?

Because when you type git push origin without a branch name, your first thought should be "hmm... is this really what I want to do?"
