Code Suggestions plugin for CodeOnTheGo

Inline ghost-text code completions. As you type, the plugin debounces, asks an LLM for a completion at the cursor, and shows it as dimmed inline text via IdeEditorService.showInlineSuggestion().

This plugin has no compile-time dependency on ai-core; it resolves the inference service at runtime through the CodeOnTheGo plugin manager (SharedServices). Install ai-core first, then this plugin, and configure a model in AI Assistant → AI Settings.

Architecture

┌──────────────────────────┐
│  code-suggestions (this) │  ← content-change listener, debounce, ghost text
└────────────┬─────────────┘
             │ SharedServices (runtime) → LlmInferenceService
             ▼
┌──────────────────────────┐
│  ai-core                 │  ← LLM inference (local llama.cpp / Gemini)
└──────────────────────────┘

Features

  • Inline ghost-text completions while typing
  • 800 ms debounce to reduce LLM load
  • LRU cache to avoid redundant calls
  • Language-aware prompts (Kotlin, Java, Python, …)
  • Graceful degradation when ai-core isn't loaded yet (binds lazily)

Permissions

This plugin declares no plugin.permissions of its own — it only registers a content-change listener and renders ghost text. Reading the configured backend/model and any network access happen inside ai-core's process, which declares those permissions.

The surrounding file content and cursor context are sent to the configured backend to generate a completion — on-device for Local, or to Google over HTTPS for Gemini. Choose the backend accordingly for sensitive code.

Building

Prerequisites: Android SDK (API 33+), JDK 17. Create local.properties with sdk.dir=.... No NDK or native toolchain.

cd code-suggestions-plugin
../gradlew assemblePlugin          # release  -> build/plugin/code-suggestions-plugin.cgp
../gradlew assemblePluginDebug     # debug variant

The build resolves plugin-api.jar from the repo-root ../libs/.

Installation

  1. Build and install ai-core first (see ../ai-core/README.md).
  2. Build this plugin, install build/plugin/code-suggestions-plugin.cgp via CodeOnTheGo's Plugin Manager, and restart the IDE.
  3. Configure a model in AI Assistant → AI Settings.
