ollie-kde

KDE-native integration for ollie — a long-lived D-Bus daemon that manages AI agent sessions, with thin KDE clients (system tray, Plasmoid, KRunner, Kate plugin, Dolphin menus).

The daemon owns all sessions and the Go runtime (libollie.so). KDE components are pure D-Bus clients — lightweight, stateless, and independently restartable.

Dependencies

• Go 1.25+
• Qt 6 (Core, DBus, Widgets, Quick) or Qt 5 (Core, DBus, Widgets, Quick, Qml)
• KDE Frameworks 6 (StatusNotifierItem, Runner, TextEditor, CoreAddons, Config) or KDE Frameworks 5 (Notifications, Runner, TextEditor, CoreAddons, Config, Plasma)
• Plasma 6 or Plasma 5 (for Plasmoid)
• ECM (Extra CMake Modules)
• ollie/core (sibling directory at ../ollie/core)

KF6/Qt6 is the default (CMakeLists.txt). To build against KF5/Qt5, point CMake at the alternate file:

cmake -S . -B build-cmake -DCMAKE_PROJECT_INCLUDE=CMakeLists-kf5.txt
# or copy/symlink it:
ln -sf CMakeLists-kf5.txt CMakeLists.txt

Build

make          # builds libollie.so (Go) then ollie-kde + ollie-tray (CMake)

Outputs:

• build/libollie.so — Go shared library (cgo c-shared)
• build-cmake/ollie-kde — D-Bus daemon
• build-cmake/ollie-tray — system tray icon
• build-cmake/lib/kf6/krunner/krunner_ollie.so — KRunner plugin (kf5/ on KF5 builds)
• build-cmake/lib/kf6/ktexteditor/ollie_kate.so — Kate plugin (kf5/ on KF5 builds)
• build-cmake/org/ollie/private/ — Plasmoid QML plugin

Install

# Daemon + tray
sudo install -m755 build-cmake/ollie-kde /usr/bin/
sudo install -m755 build/libollie.so /usr/lib64/

# KRunner plugin (use kf5/ and qt5 paths on KF5 builds)
sudo cp build-cmake/lib/kf6/krunner/krunner_ollie.so /usr/lib64/qt6/plugins/kf6/krunner/

# Kate plugin
sudo cp build-cmake/lib/kf6/ktexteditor/ollie_kate.so /usr/lib64/qt6/plugins/kf6/ktexteditor/

# Plasmoid
make plasmoid-install

# KRunner (restart needed)
make krunner-install

# Dolphin service menus
make dolphin-install

# System tray (optional standalone)
sudo install -m755 build-cmake/ollie-tray /usr/bin/

Service Setup

The daemon starts automatically via XDG autostart when you log into a KDE Plasma session. No manual service configuration is needed after make install.

To disable autostart without uninstalling:

# Per-user override
cp /etc/xdg/autostart/org.ollie.SessionManager.desktop ~/.config/autostart/
echo "Hidden=true" >> ~/.config/autostart/org.ollie.SessionManager.desktop

Manual

make run   # foreground, for development

Usage

D-Bus API

The daemon registers as org.ollie.SessionManager on the session bus.

# Create a session
dbus-send --session --dest=org.ollie.SessionManager --type=method_call --print-reply \
  /org/ollie/SessionManager org.ollie.SessionManager.CreateSession \
  string:"$HOME" string:"" string:"" string:"default"

# Submit a prompt
dbus-send --session --dest=org.ollie.SessionManager --type=method_call --print-reply \
  /org/ollie/SessionManager org.ollie.SessionManager.Submit \
  string:"<session_id>" string:"your prompt here"

# Get chat output
gdbus call --session --dest org.ollie.SessionManager --object-path /org/ollie/SessionManager \
  --method org.ollie.SessionManager.GetChat "<session_id>" 0

KRunner

• ollie <prompt> — one-shot: creates session, submits, shows popup with result
• ollie list — show active sessions
• ollie kill <id> — terminate a session

Dolphin

Right-click any file or directory:

• Ask Ollie about this — one-shot prompt with file context, shows result in kdialog
• Start Ollie session here — creates a persistent session in that directory

Kate

Enable the "Ollie" plugin in Settings → Configure Kate → Plugins. Panel appears on the right with:

• Session indicator + CWD label
• New — create session in project/file directory
• Ask File — send current file path for description
• Explain — send selected text for explanation
• Prompt input for free-form messages
• Live-streaming chat view

Plasmoid

Add the "Ollie" widget to your panel or desktop:

• Session list with state indicators (○ idle, ● thinking, ⚡ tool call)
• Live chat view with auto-scroll
• Inline prompt input
• Real-time updates via D-Bus signals

System Tray

• Tooltip: session count
• Status: passive (no sessions), active (sessions idle), attention (agent working)
• Right-click: New Session, Sessions submenu (kill each), Stop All, Quit

D-Bus Interface

Methods:

• CreateSession(cwd, backend, model, agent) → session_id
• ListSessions() → [id\tstate\tmodel\tagent, ...]
• KillSession(session_id) → success
• RenameSession(session_id, new_name) → success
• Submit(session_id, prompt) → success
• Interrupt(session_id) → success
• GetState(session_id) → state
• GetChat(session_id, offset) → text, new_offset
• GetUsage(session_id) → usage
• GetCost(session_id) → cost
• GetConfig(session_id) → key=value pairs
• SetConfig(session_id, key, value) → success
• GetContext(session_id) → JSONL messages
• ListBackends() → [names]
• ListModels(session_id) → [names]
• ListAgents() → [names]
• PeerAdd(session_id, peer_id) → success
• PeerRemove(session_id, peer_id) → success
• PeerList(session_id) → [peer_ids]
• PeerSubmit(session_id, peer_id, prompt) → success

Signals:

• SessionCreated(session_id)
• SessionKilled(session_id)
• StateChanged(session_id, new_state)
• ChatUpdated(session_id, offset, new_text)
