# Cthulhu Development Guide
## Local Development Build
To develop Cthulhu without overwriting your system installation, use the provided build scripts:
### Building Locally
```bash
# Build and install to ~/.local
./build-local.sh
# Clean build and rebuild everything
./build-local.sh --clean
```
This installs Cthulhu to `~/.local/bin/cthulhu` without touching your system installation.
### Testing the Local Build
```bash
# Test the local installation
./test-local.sh
# Run the local version directly
~/.local/bin/cthulhu --version
```
### Running Local Cthulhu
```bash
# Method 1: Direct path
~/.local/bin/cthulhu
# Method 2: Add to PATH (add to ~/.bashrc)
export PATH="$HOME/.local/bin:$PATH"
cthulhu
```
### Cleaning Up
```bash
# Clean build artifacts only
./clean-local.sh --build-only
# Remove local installation only
./clean-local.sh --install-only
# Clean everything (build artifacts + local installation)
./clean-local.sh
```
## D-Bus Remote Controller
Cthulhu now includes a D-Bus service for remote control:
- **Service**: `org.stormux.Cthulhu.Service`
- **Path**: `/org/stormux/Cthulhu/Service`
- **Requires**: `dasbus` library (should be installed)
### Testing D-Bus Service
```bash
# Start Cthulhu with D-Bus service
~/.local/bin/cthulhu
# In another terminal, test the service
busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service GetVersion
# Present a message via D-Bus
busctl --user call org.stormux.Cthulhu.Service /org/stormux/Cthulhu/Service org.stormux.Cthulhu.Service PresentMessage s "Hello from D-Bus"
```
## Development Workflow
1. **Make changes** to the code
2. **Build locally**: `./build-local.sh`
3. **Test**: `./test-local.sh`
4. **Run**: `~/.local/bin/cthulhu`
5. **Clean when done**: `./clean-local.sh --build-only`
## Git Repository Management
The `.gitignore` file is configured to exclude:
- Build artifacts (`configure`, `Makefile`, etc.)
- Generated Python files (`cthulhu_bin.py`, `cthulhu_i18n.py`, etc.)
- Python bytecode (`*.pyc`, `__pycache__/`)
Before committing:
```bash
# Clean build artifacts to avoid committing them
./clean-local.sh --build-only
# Check what will be committed
git status
```
## Dependencies
- **Runtime**: python3, pygobject-3.0, pluggy, AT-SPI2
- **Build**: autotools, gettext, intltool
- **Optional**: dasbus (for D-Bus service), BrlTTY, speech-dispatcher
Install build dependencies on Arch Linux:
```bash
sudo pacman -S autoconf automake intltool gettext python-dasbus
```

# Cthulhu Remote Controller (D-Bus Interface)
> **✅ STABLE**: This D-Bus interface has been successfully ported from Orca v49.alpha and integrated
> into Cthulhu. The API is functional and ready for use, providing external control and automation
> capabilities for the Cthulhu screen reader.
[TOC]
## Overview
Cthulhu exposes a D-Bus service at:
- **Service Name**: `org.stormux.Cthulhu.Service`
- **Main Object Path**: `/org/stormux/Cthulhu/Service`
- **Module Object Paths**: `/org/stormux/Cthulhu/Service/ModuleName`
(e.g., `/org/stormux/Cthulhu/Service/SpeechAndVerbosityManager`)
## Dependencies
The D-Bus interface requires:
- **dasbus** - Python D-Bus library used by Cthulhu for the remote controller implementation.
([Installation instructions](https://dasbus.readthedocs.io/en/latest/index.html))
- **python-dasbus** package (available on most distributions)
## Service-Level Commands
Commands available directly on the main service (`/org/stormux/Cthulhu/Service`):
### Get Cthulhu's Version
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service GetVersion
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service \
--method org.stormux.Cthulhu.Service.GetVersion
```
**Returns:** String containing the version (and revision if available)
**Example output:** `s "Cthulhu screen reader version 2025.06.05-plugins (rev 408fb85)"`
### Present a Custom Message in Speech and/or Braille
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service PresentMessage s "Your message here"
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service \
--method org.stormux.Cthulhu.Service.PresentMessage "Your message here"
```
**Parameters:**
- `message` (string): The message to present to the user
**Returns:** Boolean indicating success
### List Available Service Commands
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service ListCommands
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service \
--method org.stormux.Cthulhu.Service.ListCommands
```
**Returns:** List of (command_name, description) tuples
### List Registered Modules
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service ListModules
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service \
--method org.stormux.Cthulhu.Service.ListModules
```
**Returns:** List of module names
## Interacting with Modules
Each registered module exposes its own set of operations. Based on the underlying Cthulhu code, these
are categorized as **Commands**, **Runtime Getters**, and **Runtime Setters**:
- **Commands**: Actions that perform a task. These typically correspond to Cthulhu commands bound
to a keystroke (e.g., `IncreaseRate`).
- **Runtime Getters**: Operations that retrieve the current value of an item, often a setting
(e.g., `GetRate`).
- **Runtime Setters**: Operations that set the current value of an item, often a setting
(e.g., `SetRate`). Note that setting a value does NOT cause it to become permanently saved.
You can discover and execute these for each module.
### Discovering Module Capabilities
#### List Commands for a Module
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ListCommands
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ListCommands
```
Replace `ModuleName` with an actual module name from `ListModules`.
**Returns:** List of (command_name, description) tuples.
#### List Runtime Getters for a Module
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ListRuntimeGetters
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ListRuntimeGetters
```
Replace `ModuleName` with an actual module name from `ListModules`.
**Returns:** List of (getter_name, description) tuples.
#### List Runtime Setters for a Module
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ListRuntimeSetters
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ListRuntimeSetters
```
Replace `ModuleName` with an actual module name from `ListModules`.
**Returns:** List of (setter_name, description) tuples.
### Executing Module Operations
#### Execute a Runtime Getter
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ExecuteRuntimeGetter s 'PropertyName'
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ExecuteRuntimeGetter 'PropertyName'
```
**Parameters:**
- `PropertyName` (string): The name of the runtime getter to execute.
**Returns:** The value returned by the getter as a GLib variant (type depends on the getter).
##### Example: Get the current speech rate
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/SpeechAndVerbosityManager \
org.stormux.Cthulhu.Module ExecuteRuntimeGetter s 'Rate'
```
This will return the rate as a GLib Variant.
#### Execute a Runtime Setter
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ExecuteRuntimeSetter s 'PropertyName' v <value>
```
**Alternative using gdbus:**
```bash
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ExecuteRuntimeSetter 'PropertyName' <value>
```
**Parameters:**
- `PropertyName` (string): The name of the runtime setter to execute.
- `<value>`: The value to set, as a GLib variant (type depends on the setter).
**Returns:** Boolean indicating success.
##### Example: Set the current speech rate
```bash
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/SpeechAndVerbosityManager \
org.stormux.Cthulhu.Module ExecuteRuntimeSetter s 'Rate' v '<90>'
```
#### Execute a Module Command
```bash
# With user notification
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ExecuteCommand s 'CommandName' b true
# Without user notification (silent)
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/ModuleName \
org.stormux.Cthulhu.Module ExecuteCommand s 'CommandName' b false
```
**Alternative using gdbus:**
```bash
# With user notification
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ExecuteCommand 'CommandName' true
# Without user notification (silent)
gdbus call --session --dest org.stormux.Cthulhu.Service \
--object-path /org/stormux/Cthulhu/Service/ModuleName \
--method org.stormux.Cthulhu.Module.ExecuteCommand 'CommandName' false
```
**Parameters (both required):**
- `CommandName` (string): The name of the command to execute
- `notify_user` (boolean): Whether to notify the user of the action (see section below)
**Returns:** Boolean indicating success
### Please Note
**Setting `notify_user=true` is not a guarantee that feedback will be presented.** Some commands
inherently don't make sense to announce. For example:
```bash
# This command should simply stop speech, not announce that it is stopping speech.
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service/SpeechAndVerbosityManager \
org.stormux.Cthulhu.Module ExecuteCommand s 'InterruptSpeech' b true
```
In those cases Cthulhu will ignore the value of `notify_user`.
**Setting `notify_user=false` is a guarantee that Cthulhu will remain silent.** If Cthulhu provides any
feedback when `notify_user=false`, it should be considered a bug.
## Integration with Cthulhu's Plugin System
The D-Bus Remote Controller integrates seamlessly with Cthulhu's pluggy-based plugin system. Plugins can:
- Register their own D-Bus commands using the `@cthulhu_hookimpl` decorator
- Expose plugin-specific functionality via the remote controller
- Access the D-Bus service through the dynamic API manager
See the main `CLAUDE.md` file for more details on plugin development with D-Bus integration.
## Troubleshooting
### Service Not Available
If you get "The name is not activatable" or similar errors:
1. **Check if Cthulhu is running:**
```bash
ps aux | grep cthulhu
```
2. **Check if the D-Bus service is registered:**
```bash
busctl --user list | grep -i cthulhu
```
3. **Verify dasbus is installed:**
```bash
python3 -c "import dasbus; print('dasbus available')"
```
4. **Check Cthulhu debug output:**
```bash
DISPLAY=:0 ~/.local/bin/cthulhu --debug 2>&1 | grep -i dbus
```
### Common Issues
- **Timing Issues**: The D-Bus service starts after ATSPI initialization. Wait a few seconds after Cthulhu startup before attempting D-Bus calls.
- **Permissions**: Ensure you're using `--user` with busctl/gdbus for session bus access.
- **Display**: Make sure `DISPLAY=:0` is set when running Cthulhu in terminal sessions.
## Examples
### Quick Test Script
```bash
#!/bin/bash
# Test Cthulhu D-Bus Remote Controller
echo "Testing Cthulhu D-Bus Remote Controller..."
# Get version
echo "Version:"
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service GetVersion
# Present a message
echo "Presenting message..."
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service PresentMessage s "Hello from D-Bus!"
# List available modules
echo "Available modules:"
busctl --user call org.stormux.Cthulhu.Service \
/org/stormux/Cthulhu/Service \
org.stormux.Cthulhu.Service ListModules
echo "D-Bus test complete!"
```
## Integration Status
- ✅ **Core D-Bus service**: Fully integrated with Cthulhu
- ✅ **Service lifecycle**: Automatic start/shutdown with Cthulhu
- ✅ **Message presentation**: `PresentMessage()` method working
- ✅ **Version info**: `GetVersion()` method working
- ✅ **Deferred startup**: D-Bus service starts after ATSPI initialization to prevent crashes
- ✅ **Error handling**: Proper exception handling and logging
- 🔄 **Module registration**: Ready for individual managers to register D-Bus commands
- 🔄 **Plugin integration**: Plugins can expose D-Bus commands using decorators
## Future Development
- Add more speech configuration commands, getters, and setters
- Expose Cthulhu's plugin system commands via D-Bus
- Integrate with Cthulhu's advanced features (indentation audio, self-voicing, etc.)
- Progressively expose all of Cthulhu's commands and settings via the remote controller interface
