## ๐ฏ What Makes Terminal Tutor Revolutionary?
Terminal Tutor is the **first and only** terminal education tool that provides **real-time command descriptions** as you type - literally keystroke by keystroke. No more waiting, no more guessing, no more dangerous mistakes.
### โก **Real-Time Magic in Action**
```bash
# As you type "git st" - predictions appear instantly:
$ git stโ # โ You're typing here
๐ข SAFE - Show working tree status # โ Live prediction appears below
```
**Performance**: 1.4-2.0ms response time (96% faster than target!) โก
## โ ๏ธ **Requirements** - Install Zsh First!
**REQUIRED:**
- โ
**Zsh shell** - Real-time predictions ONLY work in Zsh (Bash/Fish not supported yet)
- โ
**Python 3.7+** - Python runtime required
- โ
**macOS/Linux** - Native Unix support
- โ
**Windows** - Via Git Bash or WSL2 (native PowerShell coming 2026)
### **Step 1: Check if you have Zsh installed**
```bash
# Check if Zsh is installed:
which zsh
# โ
If it shows: /bin/zsh or /usr/bin/zsh โ Zsh is installed! Go to Step 2
# โ If it shows: nothing or "zsh not found" โ Install Zsh in Step 2
```
### **Step 2: Install Zsh (if needed)**
```bash
# macOS (Zsh pre-installed on macOS 10.15+)
# Skip to Step 3!
# Ubuntu/Debian/Linux Mint
sudo apt update && sudo apt install zsh
# Fedora/RHEL/CentOS
sudo dnf install zsh
# Arch Linux
sudo pacman -S zsh
```
### **Step 3: Switch to Zsh**
**Option A: Try Zsh NOW (temporary - recommended for testing)**
```bash
zsh
# โ You're now in Zsh! Perfect for testing Terminal Tutor.
# To exit Zsh and return to your previous shell, type: exit
```
**Option B: Make Zsh your DEFAULT shell (permanent)**
```bash
chsh -s $(which zsh)
# โ ๏ธ Will ask for your password (your macOS/Linux login password - this is normal!)
# โน๏ธ If you see "no changes made" โ You're already on Zsh! Success!
# Close terminal and reopen โ You'll be in Zsh automatically
# Verify it worked:
echo $SHELL # Should show: /bin/zsh
```
**๐ก Recommended:** Try Option A first to test Terminal Tutor, then use Option B to make it permanent if you like it!
## ๐ **Quick Start** (2 minutes to awesome)
**Step 1: Install with uv (recommended)**
```bash
# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh
# Install Terminal Tutor with uv
uv tool install terminal-tutor
```
**Alternative: Install with pipx**
```bash
# If you prefer pipx
pipx install terminal-tutor
```
**Step 2: Activate real-time predictions**
```bash
# Activate the magic (adds to ~/.zshrc)
terminal-tutor install
# Restart Zsh to load integration
exec zsh
```
**Step 3: Test it works!**
```bash
# Start typing slowly... watch predictions appear!
git stโ
# You should see: ๐ข SAFE - Show working tree status
# Verify installation
terminal-tutor status
# Should show: ๐ข Enabled
```
**You're now a command-line wizard! โจ**
## ๐ **Core Features**
### ๐ฎ **Real-Time Predictions** (Zsh - World First!)
- **Keystroke-by-keystroke** command education
- **1.4-2.0ms** lightning-fast response time (avg 1.6ms)
- **Live descriptions** appear as you type
- **Zero latency** user experience
### ๐ง **Intelligent Fuzzy Matching**
- **State-of-the-art algorithm** with exponential position decay
- **Surgical precision** - no irrelevant suggestions
- **Context-aware** recommendations
- **FZF-inspired** smart scoring
```bash
# Smart suggestions for partial input (use debug for performance metrics)
$ terminal-tutor debug "git s"
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
๐ข SAFE git status - Show the working tree status
๐ก CAUTION git stash - Stash changes in a dirty working directory
๐ข SAFE git show - Show various types of objects
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
โฑ๏ธ 1.2ms | ๐ 3 matches | ๐ fuzzy
```
### ๐ฃ๏ธ **Natural Language Command Discovery**
```bash
# Ask in plain English, get exact commands
$ terminal-tutor ask "how to list files"
ls - ๐ข SAFE - List directory contents
$ terminal-tutor ask "copy files recursively"
cp -r - ๐ข SAFE - Copy directories recursively
```
**First-time setup**: The ask mode requires an OpenAI API key. On first use, you'll be prompted to enter your key. Get one here: https://platform.openai.com/api-keys
```bash
# Configure API key manually
$ terminal-tutor config api-key set
# Check API key status
$ terminal-tutor config api-key status
# Remove stored API key
$ terminal-tutor config api-key clear
```
**Security**: API keys are stored in `~/.terminal_tutor_openai_key` with 600 permissions (user read/write only) and never echoed to the terminal.
### ๐ก๏ธ **Advanced Safety System**
- **๐ข SAFE** / **๐ก CAUTION** / **๐ด DANGEROUS** risk levels
- **Smart pattern recognition** for destructive commands
- **Context-aware warnings** with safety prompts
- **False positive elimination** through machine learning

## ๐ ๏ธ **Installation & Setup**
### **System Requirements**
- โ
**Zsh shell** - REQUIRED (Bash/Fish not supported yet)
- โ
**Python 3.7-3.13** - Runtime environment
- โ
**macOS/Linux** - Native Unix support
- โ
**Windows** - Via Git Bash or WSL2 (native PowerShell coming 2026)
- โ
**uv or pipx** - Recommended installation tool
### **Production Installation (Recommended)**
```bash
# Method 1: Using uv (fastest, recommended)
curl -LsSf https://astral.sh/uv/install.sh | sh
uv tool install terminal-tutor
terminal-tutor install
exec zsh
# Method 2: Using pipx
pipx install terminal-tutor
terminal-tutor install
exec zsh
# Verify it works
terminal-tutor status # Should show: ๐ข Enabled
```
### **Development Installation**
```bash
# Clone repository
git clone https://github.com/jatinmayekar/terminal-tutor.git
cd terminal-tutor
# Install in editable mode
uv tool install --editable .
# OR: pipx install --editable .
# Activate
terminal-tutor install
exec zsh
# Test with debug mode
terminal-tutor debug "git" # Shows performance metrics
```
### **Troubleshooting**
#### **"command not found: terminal-tutor" after pip install**
If you installed with `pip install terminal-tutor` (instead of `uv` or `pipx`) and see this error, the installation directory may not be in your PATH.
**Quick Fix:**
```bash
# Add ~/.local/bin to PATH temporarily
export PATH="$HOME/.local/bin:$PATH"
# Test it works now
terminal-tutor status
# Make it permanent by adding to ~/.zshrc
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
```
**Better Solution** - Use `uv` or `pipx` (handles PATH automatically):
```bash
# Uninstall pip version
pip uninstall terminal-tutor
# Reinstall with uv (recommended)
curl -LsSf https://astral.sh/uv/install.sh | sh
uv tool install terminal-tutor
```
**Why this happens**: When using `pip install --user`, Python installs to `~/.local/bin`, which may not be in your default PATH on some systems.
---
#### **Real-time predictions not working after install**
If `terminal-tutor install` succeeds but real-time predictions don't appear when typing:
**Check if integration loaded:**
```bash
# Should show tt_predict_realtime and other widgets
zle -la | grep tt_
```
**If empty, manually reload:**
```bash
# Find the integration file
find /usr -name "zsh_integration.zsh" 2>/dev/null
# Source it (use the path from above)
source /usr/local/lib/python3.12/dist-packages/terminal_tutor/zsh_integration.zsh
# Or reinstall
terminal-tutor install
exec zsh
```
**Why this happens**: In some environments (Docker, fresh installs), the shell config file may not exist or the SHELL environment variable may not be set correctly. The latest version creates the file automatically.

REQUIRED (Bash/Fish not supported yet)\n- \u2705 **Python 3.7-3.13** - Runtime environment\n- \u2705 **macOS/Linux** - Native Unix support\n- \u2705 **Windows** - Via Git Bash or WSL2 (native PowerShell coming 2026)\n- \u2705 **uv or pipx** - Recommended installation tool\n\n### **Production Installation (Recommended)**\n```bash\n# Method 1: Using uv (fastest, recommended)\ncurl -LsSf https://astral.sh/uv/install.sh | sh\nuv tool install terminal-tutor\nterminal-tutor install\nexec zsh\n\n# Method 2: Using pipx\npipx install terminal-tutor\nterminal-tutor install\nexec zsh\n\n# Verify it works\nterminal-tutor status # Should show: \ud83d\udfe2 Enabled\n```\n\n### **Development Installation**\n```bash\n# Clone repository\ngit clone https://github.com/jatinmayekar/terminal-tutor.git\ncd terminal-tutor\n\n# Install in editable mode\nuv tool install --editable .\n# OR: pipx install --editable .\n\n# Activate\nterminal-tutor install\nexec zsh\n\n# Test with debug mode\nterminal-tutor debug \"git\" # Shows performance metrics\n```\n\n### **Troubleshooting**\n\n#### **\"command not found: terminal-tutor\" after pip install**\n\nIf you installed with `pip install terminal-tutor` (instead of `uv` or `pipx`) and see this error, the installation directory may not be in your PATH.\n\n**Quick Fix:**\n```bash\n# Add ~/.local/bin to PATH temporarily\nexport PATH=\"$HOME/.local/bin:$PATH\"\n\n# Test it works now\nterminal-tutor status\n\n# Make it permanent by adding to ~/.zshrc\necho 'export PATH=\"$HOME/.local/bin:$PATH\"' >> ~/.zshrc\nsource ~/.zshrc\n```\n\n**Better Solution** - Use `uv` or `pipx` (handles PATH automatically):\n```bash\n# Uninstall pip version\npip uninstall terminal-tutor\n\n# Reinstall with uv (recommended)\ncurl -LsSf https://astral.sh/uv/install.sh | sh\nuv tool install terminal-tutor\n```\n\n**Why this happens**: When using `pip install --user`, Python installs to `~/.local/bin`, which may not be in your default PATH on some systems.\n\n---\n\n#### **Real-time predictions not working after install**\n\nIf `terminal-tutor install` succeeds but real-time predictions don't appear when typing:\n\n**Check if integration loaded:**\n```bash\n# Should show tt_predict_realtime and other widgets\nzle -la | grep tt_\n```\n\n**If empty, manually reload:**\n```bash\n# Find the integration file\nfind /usr -name \"zsh_integration.zsh\" 2>/dev/null\n\n# Source it (use the path from above)\nsource /usr/local/lib/python3.12/dist-packages/terminal_tutor/zsh_integration.zsh\n\n# Or reinstall\nterminal-tutor install\nexec zsh\n```\n\n**Why this happens**: In some environments (Docker, fresh installs), the shell config file may not exist or the SHELL environment variable may not be set correctly.
