## What It Does

This tool takes your ZMK `.keymap` file (exported from the [MoErgo Glove80 Layout Editor](https://my.glove80.com/)) and generates a PDF document with a visual diagram for each layer—similar to [sunaku's layer diagrams](https://sunaku.github.io/moergo-glove80-keyboard-layers.pdf).

## Example Output

**Default output** — Shows shifted characters above keys (! above 1, @ above 2, etc.):

![Example plain output](docs/images/example-plain.png)

**With `--color` flag** — Semantic coloring by key category with legend:

![Example with color coding](docs/images/example-color.png)

**Layer with held key indicator** — Fingerprint icon shows which key activates this layer:

![Example Cursor layer with held key](docs/images/example-cursor.png)

**With `--no-shifted` flag** — Hide shifted characters for a cleaner look:

![Example without shifted characters](docs/images/example-no-shifted.png)

## Getting Started

### Step 1: Install System Dependencies

**macOS:**
```bash
brew install cairo
```

**Ubuntu/Debian:**
```bash
sudo apt-get install libcairo2-dev
```

**Windows:**
See [CairoSVG installation docs](https://cairosvg.org/documentation/#installation) for Windows instructions.

### Step 2: Install the Tool

**Option A: Install from PyPI (recommended)**
```bash
pip install glove80-keymap-visualizer
```

**Option B: Install from source**
```bash
git clone https://github.com/dsifry/glove80-keymap-visualizer.git
cd glove80-keymap-visualizer
pip install .
```

### Step 2.5: Install Browser for KLE Output (Optional)

For KLE PNG/PDF output (using keyboard-layout-editor.com styling), install Chromium:
```bash
playwright install chromium
```

This is only needed if you want to use `--format kle-png` or `--format kle-pdf`.

### Step 3: Export Your Keymap

1. Go to [my.glove80.com](https://my.glove80.com/)
2. Load your layout
3. Click **Export** → **Download ZMK Keymap**
4. Save the `.keymap` file

### Step 4: Generate Your PDF

```bash
# Basic usage - generates a PDF with all layers
glove80-viz your-keymap.keymap -o my-layers.pdf

# With color coding (recommended!)
glove80-viz your-keymap.keymap -o my-layers.pdf --color
```

That's it! Open `my-layers.pdf` to see your keyboard layout.

## Common Options

```bash
# Color-coded keys by category (modifiers, navigation, etc.)
glove80-viz keymap.keymap -o output.pdf --color

# Color-coded without the legend
glove80-viz keymap.keymap -o output.pdf --color --no-legend

# Windows modifier symbols (Win, Ctrl, Alt, Shift) instead of Mac symbols
glove80-viz keymap.keymap -o output.pdf --windows

# Show what keys do on transparent layers (instead of "trans")
glove80-viz keymap.keymap -o output.pdf --resolve-trans

# Generate only specific layers
glove80-viz keymap.keymap -o output.pdf --layers Base,Symbol,Cursor

# Control layers per page (1, 2, or 3 - default is 3)
glove80-viz keymap.keymap -o output.pdf --layers-per-page 1  # Full page per layer
glove80-viz keymap.keymap -o output.pdf --layers-per-page 2  # Two layers per page

# Custom DPI for higher/lower resolution output
glove80-viz keymap.keymap -o output.pdf --dpi 150  # Lower res, smaller file
glove80-viz keymap.keymap -o output.pdf --dpi 600  # Higher res, larger file

# Page orientation (portrait is default)
glove80-viz keymap.keymap -o output.pdf --portrait   # Portrait orientation (default)
glove80-viz keymap.keymap -o output.pdf --landscape  # Landscape orientation

# Generate SVG files instead of PDF
glove80-viz keymap.keymap -o ./svg-folder --format svg

# Generate KLE JSON (for keyboard-layout-editor.com)
glove80-viz keymap.keymap -o ./kle-folder --format kle

# Generate KLE-style PNG via headless browser (requires Chromium)
glove80-viz keymap.keymap -o ./png-folder --format kle-png

# Generate KLE-style combined PDF via headless browser
glove80-viz keymap.keymap -o output.pdf --format kle-pdf

# List all available layers in your keymap
glove80-viz keymap.keymap --list-layers
```

## Features

- **Shifted character display** — Shows shifted characters above keys (! above 1, " above ') like a physical keyboard
- **Custom mod-morph support** — Automatically detects custom shift mappings (e.g., `(` → `<`) from your keymap
- **Refined typography** — Balanced key label positioning inspired by physical keycaps, with clear visual hierarchy
- **OS-specific modifier symbols** — Mac (⌘⌥⌃⇧), Windows (Win+Ctrl+Alt+Shift), or Linux (Super+Ctrl+Alt+Shift)
- **Semantic coloring** — Color-code keys by category: modifiers, navigation, numbers, symbols, media, layers, system
- **Color legend** — Shows what each color means (can be hidden with `--no-legend`)
- **Held key indicators** — Fingerprint icon shows which key you hold to activate each layer
- **MEH/HYPER expansion** — `MEH(K)` displays as `⌃⌥⇧K` on Mac
- **Transparent key resolution** — Optionally show inherited keys instead of "trans" markers
- **Layers per page** — Control PDF density with 1, 2, or 3 layers per page (default: 3)
- **Configurable DPI** — Adjust PDF resolution for quality vs. file size tradeoff
- **Table of contents** — PDF includes clickable TOC for easy navigation
- **Layer filtering** — Generate only the layers you want
- **KLE output** — Export to keyboard-layout-editor.com JSON or render via headless browser to PNG/PDF

## Color Scheme

When using `--color`, keys are colored by category using an Everforest-inspired palette:

|----------|-------|--------------|
| Modifiers | Teal | ⌘, ⌥, ⌃, ⇧, Shift, Ctrl, Alt |
| Navigation | Green | ←, →, ↑, ↓, Home, End, PgUp, PgDn |
| Numbers | Yellow | 0-9, F1-F12 |
| Symbols | Orange | !@#$%^&*() etc. |
| Media | Light Green | ⏯, ⏭, 🔊, 🔇, brightness |
| Layer | Purple | Layer activators (held keys) |
| System | Red | Reset, Boot, Bluetooth keys |
| Mouse | Teal | Mouse movement and clicks |
| Transparent | Gray | Transparent/pass-through keys |

## Configuration File

For persistent settings, create a YAML config file:

```yaml
# my-config.yaml
os_style: mac          # "mac", "windows", or "linux"
show_colors: true
show_legend: true
show_shifted: true     # show shifted chars (default: true)
resolve_trans: false
include_toc: true
page_size: letter      # or "a4"
orientation: portrait  # "portrait" (default) or "landscape"
layers_per_page: 3     # 1, 2, or 3 layers per PDF page
dpi: 300               # output resolution (72-600 typical)
```

Then use it:
```bash
glove80-viz keymap.keymap -o output.pdf --config my-config.yaml
```

## Development

```bash
# Install with dev dependencies
pip install -e ".[dev]"

# Install browsers for KLE rendering tests
playwright install chromium

# Run tests
pytest

# Run tests with coverage
pytest --cov

# Run fast tests only (skip slow browser tests)
pytest -m "not slow"

# Format code
ruff format .

# Lint
ruff check .
```

## How It Works

1. **Parse** — Uses [keymap-drawer](https://github.com/caksoylar/keymap-drawer) to parse ZMK keymap files
2. **Extract** — Extracts layer info, key bindings, hold behaviors, and layer activators
3. **Generate SVG** — Creates SVG diagrams with keymap-drawer's layout engine
4. **Convert to PDF** — Combines SVGs into a PDF with TOC using CairoSVG and pikepdf
