LL Parser is a web application that demonstrates the LL Parsing technique used by compilers to perform top-down non-recursive parsing. This project is implemented using Python for the main logic and Streamlit for the web interface.
LL Parsing, or LL(1) Parsing, is a parsing strategy used in compiler design. It reads input from Left to Right, and constructs a Leftmost derivation of the sentence (hence LL). The (1) indicates that there is a one-symbol look-ahead in the parsing process. For more details, refer to this GeeksforGeeks article.
- Python: Used for implementing the main logic of the application.
- Streamlit: Used for creating the web interface of the application.
Follow these steps to set up the project for local development:
-
Clone the repository:
