 **Code Indexer Loop** is a Python library designed to index and retrieve code snippets. 
 
-It uses the useful indexing utilities of the **LlamaIndex** library and the multi-language **tree-sitter** library to parse the code from many popular programming languages. **tiktoken** is used to count tokens in a code snippet and **LangChain** to obtain embeddings (defaults to **OpenAI**'s `text-embedding-ada-002`) and store them in an embedded **ChromaDB** vector database. It uses **watchdog** for continuous updating of the index based on file system events.
