ECPP - a simple programing language for non nerds.

ECPP (EC++ / Easy C++) is a minimalistic programming language implemented in C++. It features basic programming constructs like functions, variables, and arithmetic operations.

Version History

v0.2.0-alpha

• Added multiplication, division, and modulo operations
• Added string interpolation with ${variable}
• Added proper scope handling for variables
• Added debug system with multiple levels
• Added improved memory management
• Added support for complex expressions

v0.1.0-alpha

• Initial release
• Basic function support
• Variable declarations
• Print statements
• Basic arithmetic (+, -)

Features

• Function declarations and calls with proper scoping
• Variable declarations and assignments
• Full arithmetic operations (+, -, *, /, %)
• String literals with variable interpolation
• Print statements
• Complex expression support with parentheses
• Comprehensive debug system
• Memory-safe implementation
• Basic error handling

Building

Windows

.\BUILD.bat

Linux/MacOS

g++ -std=c++17 -I./src/core -I./src/ast src/main.cpp src/core/.cpp -o build/ecpp

Usage

Basic usage:

./ecpp <filename.ec>

With debug output:

./ecpp <filename.ec> --debug <level>

Debug levels:

• error: Error messages only
• warn: Warnings and errors
• info: General information
• debug: Detailed debug information
• trace: Most verbose output

Language Syntax

Functions with Scoped Variables

func greet() {
    var name = "World"
    print("Hello, ${name}!")
}

main() {
    greet()
}

Variables and Arithmetic

main() {
    var x = 10
    var y = 20
    
    print("Basic arithmetic:")
    print(x + y)
    print(y - x)
    print(x * y)
    print(y / x) 
    print(y % x) 
    
    // Complex expressions
    var z = 5
    print(x * y + z) 
    print(x * (y + z)) 
}

String Interpolation

main() {
    var name = "ECPP"
    var version = "0.2.0-alpha"
    print("Welcome to ${name} version ${version}!")
}
