CodeGPT

Generates code snippets and functions by accepting natural language descriptions, leveraging the active editor's language context (detected file type, selected code region, and surrounding code structure) to produce syntactically correct output. The extension integrates with VS Code's language detection to infer the target language and applies language-specific formatting rules before inserting generated code into the editor.

Analyzes selected code blocks and generates natural language explanations of their functionality, including logic flow, variable usage, and algorithmic intent. The extension sends the selected code to the LLM backend with language-specific parsing hints, then formats the explanation as inline comments or standalone documentation that can be inserted back into the editor.

Provides a conversational interface within VS Code where developers can ask questions about code, request modifications, or seek debugging help. The chat maintains conversation history and can reference the currently selected code or open file as context, sending this context along with each message to the LLM backend to enable multi-turn conversations about specific code sections.

Enables searching for code patterns, functions, or logic by natural language description rather than keyword matching. The extension converts natural language queries into semantic embeddings and searches the current file or workspace for code that matches the intent, returning ranked results based on semantic similarity. This differs from regex or keyword search by understanding the meaning of code rather than literal text patterns.

Accepts refactoring requests in natural language (e.g., 'extract this logic into a separate function', 'rename all instances of X to Y', 'convert this callback to async/await') and applies transformations while preserving language-specific syntax, indentation, and formatting. The extension parses the selected code using language-specific rules, applies the transformation via the LLM, and validates the output against the target language's syntax before insertion.

Analyzes a selected function or code block and automatically generates unit test cases covering common scenarios (happy path, edge cases, error conditions). The extension infers the function's input/output types and expected behavior, then generates tests in the appropriate framework for the detected language (Jest for JavaScript, pytest for Python, JUnit for Java, etc.), formatted and ready to insert into a test file.

Analyzes selected code for common bugs, anti-patterns, and potential runtime errors (null pointer dereferences, type mismatches, off-by-one errors, etc.) and provides specific debugging suggestions. The extension sends code to the LLM with language-specific bug pattern hints, receives a list of potential issues with explanations, and displays them as inline diagnostics or in a dedicated panel with suggested fixes.
