QodeAssist - AI-powered coding assistant plugin for Qt Creator

QodeAssist is an AI-powered coding assistant plugin for Qt Creator. It provides intelligent code completion and suggestions for C++ and QML, leveraging large language models through local providers like Ollama. Enhance your coding productivity with context-aware AI assistance directly in your Qt development environment.

⚠️ Important Notice About Paid Providers

When using paid providers like Claude, OpenRouter or OpenAI-compatible services:

• These services will consume API tokens which may result in charges to your account
• The QodeAssist developer bears no responsibility for any charges incurred
• Please carefully review the provider's pricing and your account settings before use

Configure for using Ollama

1. Install Ollama. Make sure to review the system requirements before installation.
2. 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

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

System Prompt Configuration

The plugin comes with default system prompts optimized for chat and instruct models, as these currently provide better results for code assistance. If you prefer using FIM (Fill-in-Middle) models, you can easily customize the system prompt in the settings.

File Context Features

QodeAssist provides two powerful ways to include source code files in your chat conversations: Attachments and Linked Files. Each serves a distinct purpose and helps provide better context for the AI assistant.

Attached Files

Attachments are designed for one-time code analysis and specific queries:

• Files are included only in the current message
• Content is discarded after the message is processed
• Ideal for:
  • Getting specific feedback on code changes
  • Code review requests
  • Analyzing isolated code segments
  • Quick implementation questions
• Files can be attached using the paperclip icon in the chat interface
• Multiple files can be attached to a single message

Linked Files

Linked files provide persistent context throughout the conversation:

• Files remain accessible for the entire chat session
• Content is included in every message exchange
• Files are automatically refreshed - always using latest content from disk
• Perfect for:
  • Long-term refactoring discussions
  • Complex architectural changes
  • Multi-file implementations
  • Maintaining context across related questions
• Can be managed using the link icon in the chat interface
• Supports automatic syncing with open editor files (can be enabled in settings)
• Files can be added/removed at any time during the conversation

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.
