Overview

• AI-powered code completion
• Chat functionality:
  • Side and Bottom panels
• Support for multiple LLM providers:
  • Ollama
  • LM Studio
  • OpenAI-compatible providers(eg. https://openrouter.ai)
• Extensive library of model-specific templates
• Custom template support
• Easy configuration and model selection

Installation

1. Install Latest QtCreator
2. Install Ollama. Make sure to review the system requirements before installation.
3. Install a language models in Ollama via terminal. For example, you can run:

For standard computers (minimum 8GB RAM):

ollama run qwen2.5-coder:7b

For better performance (16GB+ RAM):

ollama run qwen2.5-coder:14b

For high-end systems (32GB+ RAM):

ollama run qwen2.5-coder:32b

4. Download the QodeAssist plugin for your QtCreator.
5. Launch Qt Creator and install the plugin:
   • Go to MacOS: Qt Creator -> About Plugins... Windows\Linux: Help -> About Plugins...
   • Click on "Install Plugin..."
   • Select the downloaded QodeAssist plugin archive file

Configure Plugin

QodeAssist comes with default settings that should work immediately after installing a language model. The plugin is pre-configured to use Ollama with standard templates, so you may only need to verify the settings.

1. Open Qt Creator settings (Edit > Preferences on Linux/Windows, Qt Creator > Preferences on macOS)
2. Navigate to the "Qode Assist" tab
3. On the "General" page, verify:
   • Ollama is selected as your LLM provider
   • The URL is set to http://localhost:11434
   • Your installed model appears in the model selection
   • The prompt template is Ollama Auto FIM
4. Click Apply if you made any changes

You're all set! QodeAssist is now ready to use in Qt Creator.

Supported LLM Providers

QodeAssist currently supports the following LLM (Large Language Model) providers:

• Ollama
• LM Studio
• OpenRouter
• OpenAI compatible providers

Recommended Models:

QodeAssist has been thoroughly tested and optimized for use with the following language models:

• Qwen2.5-coder
• CodeLlama
• StarCoder2
• DeepSeek-Coder-V2

Model Types

FIM models (codellama:7b-code, starcoder2:7b, etc.) - Optimized for code completion and suggestions

Instruct models (codellama:7b-instruct, starcoder2:instruct, etc.) - Better for chat assistance, explanations, and code review

For best results, use FIM models with code completion and Instruct models with chat features.

Ollama:

For autocomplete(FIM)

ollama run codellama:7b-code
ollama run starcoder2:7b
ollama run qwen2.5-coder:7b-base
ollama run deepseek-coder-v2:16b-lite-base-q3_K_M

For chat and instruct

ollama run codellama:7b-instruct
ollama run starcoder2:instruct
ollama run qwen2.5-coder:7b-instruct
ollama run deepseek-coder-v2

Template-Model Compatibility

Note:

• FIM (Fill-in-Middle) templates are optimized for code completion
• Chat templates are designed for interactive dialogue
• The Ollama Auto templates automatically adapt to most Ollama models
• Custom Template allows you to define your own prompt format

QtCreator Version Compatibility

• QtCreator 15.0.0 - 0.4.x
• QtCreator 14.0.2 - 0.2.3 - 0.3.x
• QtCreator 14.0.1 - 0.2.2 plugin version and below

Development Progress

• Basic plugin with code autocomplete functionality
• Improve and automate settings
• Add chat functionality
• Sharing diff with model
• Sharing project source with model
• Support for more providers and models

Hotkeys

• To call manual request to suggestion, you can use or change it in settings
  • on Mac: Option + Command + Q
  • on Windows: Ctrl + Alt + Q
• To insert the full suggestion, you can use the TAB key
• To insert word of suggistion, you can use Alt + Right Arrow for Win/Lin, or Option + Right Arrow for Mac

Troubleshooting

If QodeAssist is having problems connecting to the LLM provider, please check the following:

1. Verify the IP address and port:

   • For Ollama, the default is usually http://localhost:11434
   • For LM Studio, the default is usually http://localhost:1234

2. Check the endpoint:

Make sure the endpoint in the settings matches the one required by your provider - For Ollama, it should be /api/generate - For LM Studio and OpenAI compatible providers, it's usually /v1/chat/completions

3. Confirm that the selected model and template are compatible:

Ensure you've chosen the correct model in the "Select Models" option Verify that the selected prompt template matches the model you're using

If you're still experiencing issues with QodeAssist, you can try resetting the settings to their default values:

1. Open Qt Creator settings
2. Navigate to the "Qode Assist" tab
3. Pick settings page for reset
4. Click on the "Reset Page to Defaults" button
   • The API key will not reset
   • Select model after reset

How to Build

Create a build directory and run

cmake -DCMAKE_PREFIX_PATH=<path_to_qtcreator> -DCMAKE_BUILD_TYPE=RelWithDebInfo <path_to_plugin_source>
cmake --build .

where <path_to_qtcreator> is the relative or absolute path to a Qt Creator build directory, or to a combined binary and development package (Windows / Linux), or to the Qt Creator.app/Contents/Resources/ directory of a combined binary and development package (macOS), and <path_to_plugin_source> is the relative or absolute path to this plugin directory.
