Liquid Language Interpreter

This project is a TypeScript-based interpreter for a custom language named "Liquid". The project is organized into several modules, each with a specific role in the interpretation process.

Project Structure

The project is divided into several directories:

• src/: Contains the source code of the interpreter.
  • common/: Contains helper functions and type definitions.
  • core/: Contains the core components of the interpreter, including the lexer, parser, and runtime.
  • lang/: Contains language-specific definitions, such as grammar and patterns.
• tests/: Contains test files for the lexer.

Core Components

• Lexer (src/core/lexer.ts): Transforms a source code string into a sequence of tokens.
• Parser (src/core/parser.ts): Transforms a sequence of tokens into an Abstract Syntax Tree (AST).
• Runtime (src/core/runtime.ts): Executes the AST and produces a result.

Usage

To run the interpreter, use the dev script defined in the package.json file:

npm run dev

This will execute the src/index.ts file, which serves as the entry point of the interpreter.

Testing

Tests are located in the tests/ directory. Currently, there are tests for the lexer. run test using :

npm run test

Linting and Formatting

The project uses ESLint for linting and Prettier for code formatting. You can run the linter and formatter using the following commands:

npm run lint
npm run format
