## Features

- Generate quiz questions on any topic using Gemini Flash 2.5
- Multiple choice and True/False question types
- Two quiz modes: Interactive (question-by-question) and Batch (all at once)
- **CLI Interface**: Terminal-based with arrow key navigation and configurable styling
- **Streamlit Web UI**: Modern web interface with visualizations and interactive charts
- Minimal configuration by default, advanced options available
- Built with Pydantic for data validation

## CLI Styling and Accessibility

Quli ships with configurable, accessible CLI styling. It uses Rich (already a dependency) and prompt-toolkit.

### Themes
- classic (default when color is available)
- high-contrast (better readability with strong colors)
- auto (chooses based on terminal capabilities)

Select with:

```bash
uv run quli --style auto        # or classic, high-contrast
```

### Symbols and Fonts
- Unicode symbols are used when supported by your terminal/locale.
- Nerd Font glyphs are used when available/preferred (e.g., JetBrains Mono Nerd Font). If unavailable, Quli falls back to Unicode or ASCII.

Overrides:

```bash
uv run quli --ascii                 # force ASCII-only symbols
uv run quli --unicode               # force Unicode symbols (if supported)
uv run quli --nerd-font             # prefer Nerd Font glyphs
uv run quli --no-nerd-font          # disable Nerd Font glyphs
```

Environment hints:
- Respect `NO_COLOR` (disables colors)
- Respect `TERM=dumb` (disables colors)
- Optional `NERD_FONT=1` to hint Nerd Font availability

### Accessibility Notes
- High-contrast theme emphasizes readability with minimal decoration.
- ASCII fallbacks ensure compatibility on limited environments.
- Unicode/nerd glyphs are only used when your terminal supports them.

### Example

```bash
uv run quli --style high-contrast --nerd-font
```

```

## Installation

1. Install uv (if not already installed):
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```

2. Install dependencies:
```bash
uv sync
```

3. Set up environment variables:
```bash
cp .env.example .env
# Edit .env and add your GEMINI_API_KEY
```

## Environment Variable Configuration

Quli supports flexible environment variable loading from multiple sources with a clear priority order. This allows you to configure the tool in a way that best fits your workflow.

### Priority Order

Environment variables are loaded in the following priority order (higher priority overrides lower):

1. **CLI arguments** (via `--env-file` option) - **Highest Priority**
2. **Standard input (stdin)**: piped or interactive entry
3. **`.zshenv` file** (if zsh is installed): checked in current directory first, then `~/.zshenv`
4. **`.env` file** (project root directory)
5. **System environment variables** (already set in your shell) - **Lowest Priority**

### Configuration Methods

#### 1. System Environment Variables

Set environment variables in your shell session:

```bash
export GEMINI_API_KEY="your-api-key-here"
```
```bash 
quli -t "Python"
```

#### 2. `.env` File (Project Root)

Create a `.env` file in your project root:

```bash
# .env
GEMINI_API_KEY=your-api-key-here
```

This is the traditional method and works automatically when you run Quli.

#### 3. `.zshenv` File (Zsh Users)

If you use zsh, Quli will automatically check for `.zshenv` files:

- **Current directory**: `./.zshenv` (checked first)
- **Home directory**: `~/.zshenv` (checked if current directory file doesn't exist)

Example `.zshenv` file:

```bash
# .zshenv
export GEMINI_API_KEY="your-api-key-here"
# Other environment variables
export CUSTOM_VAR="value"
```

**Note**: Quli only reads `.zshenv` files if zsh is installed on your system. If zsh is not available, this method is skipped.

#### 4. Standard Input (Piped)

Pipe environment variables from a file or command:

```bash
# From a file
cat .env | quli -t "Python"

# From echo
echo "GEMINI_API_KEY=your-key" | quli -t "Python"

# Multiple variables
cat <<EOF | quli -t "Python"
GEMINI_API_KEY=your-key
CUSTOM_VAR=value
EOF
```

**Supported formats:**
- `KEY=value`
- `export KEY=value`

#### 5. Interactive Prompting

If no environment variables are found and you're running Quli interactively (not piped), you'll be prompted to enter them:

```bash
quli -t "Python"
# If GEMINI_API_KEY is not set, you'll see:
# Enter environment variables (KEY=value format, one per line).
# Press Enter on empty line to finish, or Ctrl+D.
```

Enter variables one per line:
```
GEMINI_API_KEY=your-api-key-here
CUSTOM_VAR=value

# Press Enter on empty line to finish
```

#### 6. Custom Environment File (`--env-file`)

Specify a custom environment file path:

```bash
quli --env-file /path/to/custom.env -t "Python"
```

The file should be in standard `.env` format (KEY=value pairs).

### Examples

**Using .zshenv (automatic for zsh users):**
```bash
# Create .zshenv in your project directory
echo 'export GEMINI_API_KEY="your-key"' > .zshenv
quli -t "Python"  # Automatically loads from .zshenv
```

**Piping from stdin:**
```bash
echo "GEMINI_API_KEY=test-key" | quli -t "Test Quiz"
```

**Interactive entry:**
```bash
quli -t "Python"
# When prompted, enter:
# GEMINI_API_KEY=your-key
# [Press Enter on empty line]
```

**Using custom env file:**
```bash
quli --env-file ~/.config/quli.env -t "Python"
```

**Combining methods (priority example):**
```bash
# .env has: GEMINI_API_KEY=env-key
# stdin has: GEMINI_API_KEY=stdin-key
echo "GEMINI_API_KEY=stdin-key" | quli -t "Python"
# Result: Uses stdin-key (stdin overrides .env)
```

### Troubleshooting

**Environment variable not found:**
- Check that the variable is set in at least one of the supported sources
- Verify the variable name is correct (case-sensitive)
- For `.zshenv`, ensure zsh is installed (`which zsh`)
- Try using `--env-file` to explicitly specify a file

**`.zshenv` not being read:**
- Verify zsh is installed: `which zsh` or `zsh --version`
- Check file exists: `ls -la .zshenv` or `ls -la ~/.zshenv`
- Ensure file has correct format (KEY=value or export KEY=value)

**Interactive prompt not appearing:**
- Interactive prompts only appear when stdin is a TTY (not piped)
- If you're piping input, variables should be in the piped data
- Check that `GEMINI_API_KEY` is actually missing: `echo $GEMINI_API_KEY`

**Variable format issues:**
- Use `KEY=value` format (no spaces around =)
- For values with spaces, use quotes: `KEY="value with spaces"`
- Comments start with `#`
- Empty lines are ignored

## Usage

### Command-Line Options

| Option          | Short | Description                                                             |
| --------------- | ----- | ----------------------------------------------------------------------- |
| `--topic`       | `-t`  | Topic for the quiz (e.g., "Python programming")                         |
| `--interactive` | `-i`  | Run in interactive mode (question-by-question with immediate feedback)  |
| `--batch`       | `-b`  | Run in batch mode (answer all questions, then see results)              |
| `--advanced`    | `-a`  | Use advanced configuration (customize difficulty, question types, etc.) |
| `--env-file`    | `-e`  | Path to custom environment file (.env format) to load                   |

**Note:** If no topic is provided, the app will prompt for advanced configuration interactively.

### Basic Usage (Minimal Config)

The simplest way to run a quiz is to provide just a topic. By default, this runs in interactive mode with 5 questions:

```bash
uv run quli --topic "Python programming"
```

This will:
- Generate 5 questions about Python programming
- Include both multiple choice and true/false questions
- Use mixed difficulty levels
- Show immediate feedback after each answer

### Interactive Mode

Interactive mode shows one question at a time with immediate feedback after each answer:

```bash
uv run quli --topic "Python programming" --interactive
```

**What to expect:**
- Questions are displayed one at a time
- After answering, you'll see if you were correct or incorrect
- The correct answer is shown if you got it wrong
- Explanations are displayed when available
- Press Enter to continue to the next question
- Final results are shown at the end

**Example flow:**
```
Question 1/5: What is the output of print(2 + 2)?
A) 3
B) 4
C) 5
D) 6

[Use arrow keys to select, Enter to confirm]
✓ Correct!

Press Enter to continue
```

### Batch Mode

Batch mode lets you answer all questions first, then shows your results at the end:

```bash
uv run quli --topic "Python programming" --batch
```

**What to expect:**
- All questions are displayed sequentially
- You answer each question without immediate feedback
- After answering all questions, you'll see:
  - Your final score (percentage)
  - Number of correct answers
  - Total time taken
  - Review of all questions with your answers and correct answers

**Use case:** Best for timed quizzes or when you want to answer all questions before seeing results.

### Advanced Configuration

Run without arguments or use the `--advanced` flag to access interactive configuration:

```bash
uv run quli
# or
uv run quli --advanced
```

**Configuration options:**
- **Topic:** Enter any topic for your quiz
- **Number of questions:** Choose how many questions (default: 5)
- **Difficulty level:** Easy, Medium, Hard, or Mixed (default)
- **Question types:** Multiple Choice only, True/False only, or Both (default)

**Example:**
```bash
uv run quli --advanced --topic "Machine Learning" --interactive
```

### Answering Questions

**Multiple Choice Questions:**
- Use **arrow keys** (↑/↓) to navigate between options
- Press **Enter** to confirm your selection
- Or type the option letter (A, B, C, D) and press Enter
- If arrow keys don't work, you'll be prompted to type the option number

**True/False Questions:**
- Use **arrow keys** (↑/↓) to select True or False
- Press **Enter** to confirm
- Or type "True" or "False" directly

**Keyboard Shortcuts:**
- `Ctrl+C`: Cancel the quiz at any time
- `Enter`: Confirm selection or continue to next question
- `↑/↓`: Navigate options (in interactive input mode)

### Examples

**Quick quiz on a specific topic:**
```bash
uv run quli -t "JavaScript"
```

**Hard difficulty quiz with 10 questions:**
```bash
uv run quli -a -t "Data Structures" -i
# Then select: 10 questions, Hard difficulty
```

**Batch mode for timed practice:**
```bash
uv run quli -t "Algorithms" -b
```

**True/False only quiz:**
```bash
uv run quli -a -t "History"
# Then select: True/False only
```

## Streamlit Web Interface

Quli includes a modern web-based interface built with Streamlit, providing an intuitive alternative to the CLI with visual feedback and interactive charts.

### Launching the Streamlit App

After installing dependencies, launch the web interface:

```bash
streamlit run src/quli_quiz/streamlit_app.py
