- **Speech driver**: speechdDriver (via speech-dispatcher)
- **Input driver**: evdevDriver (Linux) or ptyDriver (other platforms)
- **Screen driver**: vcsaDriver (Linux TTY) or ptyDriver (terminal emulation)
## Getting Started
### Basic Usage
1. **Start Fenrir**:
```bash
sudo systemctl start fenrir # If installed as service
# OR
sudo fenrir # Run directly
```
2. **Basic Navigation**:
- **Fenrir Key**: By default `Insert`, `Keypad Insert`, or `Meta/Super` key
- **Tutorial Mode**: `Fenrir + H` to learn all commands interactively
- **Quit Fenrir**: `Fenrir + Q`
3. **Essential Commands**:
- `Ctrl` - Stop speech (shut up)
- `Fenrir + Keypad 5` - Read current screen
- `Keypad 8` - Read current line
- `Keypad 5` - Read current word
- `Keypad 2` - Read current character
- `Fenrir + T` - Announce time
- `Fenrir + S` - Spell check current word
### Keyboard Layouts
Fenrir supports two main keyboard layouts:
- **Desktop Layout**: Uses numeric keypad for navigation (recommended for desktop users)
- **Laptop Layout**: Alternative bindings for keyboards without numeric keypad
Configure in `/etc/fenrir/settings/settings.conf`:
```ini
[keyboard]
keyboardLayout=desktop # or 'laptop'
```
### First Time Setup
1. **Enable Fenrir at boot**:
```bash
sudo systemctl enable fenrir
```
2. **Configure audio** (if needed):
- For PulseAudio: Run configure_pulse.sh script (see below)
- For PipeWire: Run configure_pipewire.sh script (see below)
3. **Test speech**:
```bash
# Test speech-dispatcher directly
sudo spd-say "Hello World"
```
## Remote Control
Fenrir includes a powerful remote control system that allows external applications and scripts to control Fenrir through Unix sockets or TCP connections. This is particularly useful for automation, integration with other applications, or providing alternative control methods.
### Configuration
Enable remote control in `/etc/fenrir/settings/settings.conf`:
```ini
[remote]
enable=True
driver=unixDriver # or tcpDriver
port=22447 # for TCP driver
socketFile= # custom socket path (optional)
enableSettingsRemote=True # allow settings changes
enableCommandRemote=True # allow command execution
```
### Remote Drivers
1. **unixDriver** (recommended): Uses Unix domain sockets
- Socket location: `/tmp/fenrirscreenreader-deamon.sock` (TTY mode) or `/tmp/fenrirscreenreader-<pid>.sock`
- More secure, local-only access
- Works with `socat`
2. **tcpDriver**: Uses TCP sockets on localhost
- Default port: 22447
- Works with `netcat`, `telnet`, or any TCP client
- Local connections only (127.0.0.1)
### Using socat with Unix Sockets
The `socat` command provides the easiest way to send commands to Fenrir:
#### Basic Speech Control
```bash
# Interrupt current speech
echo "command interrupt" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Speak custom text
echo "command say Hello, this is a test message" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Temporarily disable speech (until next keystroke)
echo "command tempdisablespeech" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
#### Settings Control
```bash
# Enable highlight tracking mode
echo "setting set focus#highlight=True" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Change speech parameters
echo "setting set speech#rate=0.8" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set speech#pitch=0.6" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set speech#volume=0.9" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Change punctuation level (none/some/most/all)
echo "setting set general#punctuationLevel=all" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set general#punctuationLevel=none" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Voice and TTS engine control
echo "setting set speech#voice=en-us+f3" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set speech#module=espeak-ng" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Disable sound temporarily
echo "setting set sound#enabled=False" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set sound#volume=0.5" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Keyboard and input settings
echo "setting set keyboard#charEchoMode=1" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting set keyboard#wordEcho=True" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Screen control (ignore specific TTYs)
echo "setting set screen#ignoreScreen=1,2,3" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Multiple settings at once
echo "setting set speech#rate=0.8;sound#volume=0.7;general#punctuationLevel=most" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Reset all settings to defaults
echo "setting reset" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Save current settings
echo "setting save" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
echo "setting saveas /tmp/my-fenrir-settings.conf" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
#### Clipboard Operations
```bash
# Place text into clipboard
echo "command clipboard This text will be copied to clipboard" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Export clipboard to file
echo "command exportclipboard" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
#### Window Management
```bash
# Define a window area (x1 y1 x2 y2)
echo "command window 0 0 80 24" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Reset window to full screen
echo "command resetwindow" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
#### VMenu Control
```bash
# Set virtual menu context
echo "command vmenu nano/file" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Reset virtual menu
echo "command resetvmenu" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
#### Application Control
```bash
# Quit Fenrir
echo "command quitapplication" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
```
### Using TCP Driver
If using the TCP driver, replace socat commands with netcat:
```bash
# Using netcat
echo "command say Hello from TCP" | nc localhost 22447
# Using telnet
echo "command interrupt" | telnet localhost 22447
```

fenrir_interrupt
```
#### Python Integration
```python
#!/usr/bin/env python3
import socket
import os
def send_fenrir_command(command):
"""Send command to Fenrir via Unix socket"""
socket_path = "/tmp/fenrirscreenreader-deamon.sock"
if os.path.exists(socket_path):
sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
try:
sock.connect(socket_path)
sock.send(command.encode('utf-8'))
finally:
sock.close()
# Examples
send_fenrir_command("command say Processing complete")
send_fenrir_command("setting set speech#rate=0.9")
```
### Security Considerations
- Unix sockets are accessible only to the user running Fenrir
- TCP driver binds only to localhost (127.0.0.1)
- Socket file permissions are set to write-only (0o222)
- Commands are processed with Fenrir's privileges
- Settings changes can be disabled via `enableSettingsRemote=False`
- Command execution can be disabled via `enableCommandRemote=False`
### Troubleshooting
**Socket not found:**
- Verify Fenrir is running: `ps aux | grep fenrir`
- Check socket location: `/tmp/fenrirscreenreader-*`
- Ensure remote driver is enabled in settings
**Commands not working:**
- Verify `enableCommandRemote=True` in settings
- Check Fenrir debug logs: `/var/log/fenrir.log`
- Test with simple command: `echo "command interrupt" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock`

- **onScreenUpdate**: Triggered on screen content changes
- **onKeyInput**: Triggered on key presses
- **onByteInput**: Triggered on byte-level input
- **onScreenChanged**: Triggered when switching screens
## Development Setup
### Requirements
- Python 3.6+
- python3-evdev
- python3-pyudev
- speech-dispatcher
- sox
### Getting Started
```bash
# Clone repository
git clone https://git.stormux.org/storm/fenrir.git
cd fenrir
# Install dependencies
sudo pip3 install -r requirements.txt
# Run from source
cd src/
sudo ./fenrir -f -d
```
### Testing
```bash
# Run in debug mode
sudo ./fenrir -f -d -p
# Debug output goes to:
# - Console (with -p flag)
# - /var/log/fenrir.log
```
## Creating Commands
### Basic Command
Create a file in `src/fenrirscreenreader/commands/commands/`:
```python
from fenrirscreenreader.core import debug
class command():
def __init__(self):
pass
def initialize(self, environment):
self.env = environment
def shutdown(self):
pass
def getDescription(self):
return _('My custom command')
def run(self):
# Get current text
text = self.env['screen']['newContentText']
# Speak something
self.env['runtime']['outputManager'].presentText('Hello World')
# Play sound
self.env['runtime']['outputManager'].playSoundIcon('Accept')
```
### Key Bindings
Add key bindings in keyboard layout files:
`config/keyboard/desktop.conf` or `config/keyboard/laptop.conf`
```ini
[KEY_CTRL]#[KEY_ALT]#[KEY_H]=my_command
```
### Event Hooks
Create event handlers in appropriate directories:
```python
# onCursorChange/my_hook.py
class command():
def __init__(self):
pass
def initialize(self, environment):
self.env = environment
def shutdown(self):
pass
def getDescription(self):
return _('My cursor change handler')
def run(self):
if self.env['runtime']['cursorManager'].isCursorHorizontalMove():
# Handle horizontal cursor movement
pass
```
## Creating Drivers
### Driver Template
```python
class driver():
def __init__(self):
pass
def initialize(self, environment):
self.env = environment
def shutdown(self):
pass
# Driver-specific methods...
```
### Input Driver
Implement these methods:
- `getInputEvent()`: Return input events
- `writeEventBuffer()`: Handle output events
- `grabDevices()`: Take exclusive control
- `releaseDevices()`: Release control
### Screen Driver
Implement these methods:
- `getCurrScreen()`: Get current screen content
- `getSessionInformation()`: Get session info
### Speech Driver
Implement these methods:
- `speak()`: Speak text
- `cancel()`: Stop speech
- `setCallback()`: Set callback functions
### Remote Driver
Implement these methods:
- `initialize()`: Setup socket/connection
- `watchDog()`: Listen for incoming commands
- `shutdown()`: Clean up connections
#### Remote Driver Example
```python
class driver(remoteDriver):
def initialize(self, environment):
self.env = environment
# Start watchdog thread
self.env['runtime']['processManager'].addCustomEventThread(
self.watchDog, multiprocess=True
)
def watchDog(self, active, eventQueue):
# Listen for connections and process commands
while active.value:
# Accept connections
# Parse incoming data
# Send to event queue
eventQueue.put({
"Type": fenrirEventType.RemoteIncomming,
"Data": command_text
})
```
## Configuration
### Settings System
Settings are hierarchical:
1. Command-line options (`-o`)
2. Configuration file
3. Hard-coded defaults
### Adding Settings
1. Add default value to `core/settingsData.py`
2. Access via `self.env['runtime']['settingsManager'].getSetting(section, key)`
## Debugging
### Debug Levels
- 0: DEACTIVE
- 1: ERROR
- 2: WARNING
- 3: INFO
### Debug Output
```python
self.env['runtime']['debug'].writeDebugOut(
'Debug message',
debug.debugLevel.INFO
)
```
### Testing Commands
```bash
# Test specific functionality
sudo fenrir -f -d -o "general#debugLevel=3"
# Test with custom config
sudo fenrir -f -s /path/to/test.conf
```

environment = {
'runtime': {
'settingsManager': settingsManager,
'commandManager': commandManager,
'screenManager': screenManager,
'inputManager': inputManager,
'outputManager': outputManager,
'debug': debugManager,
# ... other managers
},
'screen': {
'newContentText': '',
'oldContentText': '',
'newCursor': {'x': 0, 'y': 0},
'oldCursor': {'x': 0, 'y': 0},
# ... screen data
},
'general': {
'prevCommand': '',
'currCommand': '',
# ... general data
}
}
```
### Common Operations

=== Remote Control
Fenrir includes a powerful remote control system that allows external applications and scripts to control Fenrir through Unix sockets or TCP connections.
==== Configuration
Enable remote control in settings.conf:
....
[remote]
enable=True
driver=unixDriver
enableSettingsRemote=True
enableCommandRemote=True
....
==== Using socat with Unix Sockets
The `+socat+` command provides the easiest way to send commands to Fenrir:
===== Basic Speech Control
....
# Interrupt current speech
echo "command interrupt" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Speak custom text
echo "command say Hello, this is a test message" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Temporarily disable speech (until next keystroke)
echo "command tempdisablespeech" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
....
===== Settings Control
....
# Enable highlight tracking mode
echo "setting set focus#highlight=True" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Change speech rate
echo "setting set speech#rate=0.8" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Change punctuation level (none/some/most/all)
echo "setting set general#punctuationLevel=all" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Voice and TTS control
echo "setting set speech#voice=en-us+f3" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Multiple settings at once
echo "setting set speech#rate=0.8;sound#volume=0.7;general#punctuationLevel=most" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Reset all settings to defaults
echo "setting reset" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
....
===== Clipboard Operations
....
# Place text into clipboard
echo "command clipboard This text will be copied to clipboard" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
# Export clipboard to file
echo "command exportclipboard" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
....
===== Application Control
....
# Quit Fenrir
echo "command quitapplication" | socat - UNIX-CLIENT:/tmp/fenrirscreenreader-deamon.sock
....
