CodeGenLink is a Visual Studio Code extension that interacts with GitHub Copilot Chat to generate code, analyze its origin, and identify the associated license.
- OpenAI token
- Python >= 3.9.x
- For the extension to work properly, you need to 8000 install:
CCFinderSW is a token-based clone detector, at the moment, it support programming languages such as:
- Python
- Java
- Ruby
- PHP
- Go
- C
- C++
- C#
- ...
For the full list visit CCFinderSW.
If you want to support other programming languages, you can extend it following the guideline provided by the authors of the tool.
Generates code via GitHub Copilot Chat and retrieves source links used during generation (web search is powered by the OpenAI tool tool_web_search). Uses cosine similarity and clone ratio to identify the most relevant sources and extract their licenses based on the domain.
Analyzes selected code to find matching sources on the web (web search powered by tool_web_search), using similarity metrics, and extracts the license from each identified source.
For users, to install a .vsix file in VS Code:
-
From the Extensions view in VS Code:
Go to the
Extensions view > Select Views and More Actions... > Install from VSIX... -
From the command line:
# If you use VS Code code --install-extension codegenlink-0.0.1.vsix# If you use VS Code Insiders code-insiders --install-extension codegenlink-0.0.1.vsix
You can configure the working parameters by following the instructions below:
- For Windows: Go to the menu
File > Preferences > Settingsand searchCodeGenLink Settings. - For macOS: Go to the menu
Code > Settingsand searchCodeGenLink Settings.
- AI model: Specify the OpenAI model to use (e.g.,
gpt-4o,gpt-4.1). Refer to the OpenAI documentation for supported models. (Default:gpt-4o) - APIKey: Your OpenAI API key.
- Temperature: Controls creativity vs determinism. Higher values = more creative. (Default:
1) - minLines: Minimum number of code lines (excluding blanks) for both extracted and generated snippets. (Default:
5) - cloneRatioThreshold: Clone ratio threshold to include code from a source. (Default:
60) - cosineSimilarityThreshold: Cosine similarity threshold to include source links. (Default:
0.6) - CCFinderSWPath: Path to the
CCFinderSWexecutable. - outputDir: Directory to store analysis results.
- minTokenLength: Minimum token sequence length for CCFinderSW clone detection. (Default:
20) - licenseclassifierPath: Path to the folder containing
identify_license.gofor license classification.
The usage differs depending on the selected functionality:
- CodeGenLink: In the Copilot Chat input prompt, type your request prefixed with the tag
@CodeGenLink. This will trigger code generation and source/license detection. - LinkSearcher: Select the code in the editor, right-click, and choose "Send Selected Code to Copilot". The extension will automatically analyze the selection and retrieve possible source links and license information.
You are a Senior <<LANGUAGE>> developer. Then give me a <<LANGUAGE>> code snippet about: <<QUERY>>.
You don’t need to explicitly ask for a web search — the extension automatically performs it using an embedded secondary query:
Search the web to find links where I can get more information about this code. <<LANGUAGE>>, <<CLEAN_CODE>>
Once the analysis is completed (via either CodeGenLink or LinkSearcher), the results are shown through a dedicated button located in the bottom-right corner of the Visual Studio Code status bar.
Clicking this button opens a view containing all the source links identified for the generated or selected code. Only links that exceed at least one of the two configured thresholds are displayed:
cloneRatioThresholdcosineSimilarityThreshold
For each listed link, the associated license (if detectable) is also shown.
