# SimpAlg Language Parser
This project defines a simple programming language called **SimpAlg**, which supports basic variable declarations, control structures, and arithmetic/boolean expressions. The project uses ANTLR to generate a lexer and parser based on the defined grammar.
## Overview
The **SimpAlg** language consists of two main sections:
1. **Variable Declarations** - where variables of type `int` and `float` are declared.
2. **Program Commands** - where the main logic of the program is defined with commands such as printing, reading input, conditional statements (`if`), loops (`while`), and assignments.
The language supports arithmetic and boolean expressions, basic I/O operations, and standard control flow structures.
## Grammar Structure
The grammar for **SimpAlg** is written in ANTLR and defines the following:
- Variable declarations (supporting `int` and `float` types).
- Basic commands including `print`, `scan`, assignments, conditionals (`if`), and loops (`while`).
- Arithmetic and boolean expressions with standard operators.
## Installation
### Prerequisites
- **Java** (version 8 or higher)
- **ANTLR** (version 4)
### Steps
1. **Install ANTLR:**
Follow the official installation guide for [ANTLR](https://www.antlr.org/).
2. **Generate Lexer and Parser:**
After cloning the repository, generate the lexer and parser using ANTLR:
```bash
antlr4 SimpAlg.g4
```
3. **Compile the Java Code:**
```bash
javac Main.java
```
4. **Run the Main Program:**
```bash
java Main
```
## Usage
1. Write your SimpAlg program in a file, for example teste.txt.
2. Run the main program to parse and analyze the code.
3. The program will output the parse tree in the console.
