Custom Language Builder

Overview

A revolutionary web application that empowers developers to create custom programming languages through an intuitive visual interface. This tool changes everything by providing a Visual Language Designer to define syntax via drag-and-drop, generating working compilers and complete language toolchains instantly.

Platform

Mobile App View on GitHub
Backend & Compiler View on GitHub

Technologies

Flutter Web

Used for the intuitive, drag-and-drop visual IDE and web interface.

Python

Powers the backend server and the core compiler generation logic.

Compiler Core

Generates the Lexical Analyzer, Syntax Parser, Semantic Analyzer, and Code Generator.

Visual AST Builder

Allows users to define the Abstract Syntax Tree and language structure visually.
