Cimple Docs

CIMPLE (pronounced "simple") is a high-level programming language that merges Python-like syntax with C++ performance. It is designed to be beginner-friendly like Python, but compiled and optimized like C++. CIMPLE files (.cimp) are translated into native C++ code and compiled via g++.

This version, CIMPLE v0.2 Beta, introduces foundational programming features and builds a bridge between readability and raw power.

Python-style syntax (print(), cin(), indentation-based blocks with : and end)
Type declarations (int, float, string, etc.)
Arithmetic, comparison, logical, and bitwise operations
Conditionals (if, else) and Loops (while, for)
User-defined functions, single-line and multi-line comments
C++-style cin() input supported
Modular imports using import cimple.module
Compiles to C++ (translates to .cpp and builds to .out)

.cimp files: Source code files written in CIMPLE
output.cpp: Auto-generated as translated C++ code
run.out: The final compiled executable

CIMPLE modularizes C++ headers into grouped import aliases:

CIMPLE Import	Includes
`import cimple.inout`	iostream, fstream, sstream, iomanip
`import cimple.data`	vector, list, deque, map, set, unordered_map
`import cimple.algo`	algorithm
`import cimple.math`	cmath, numeric, complex, valarray, random
`import cimple.util`	utility, memory, tuple, chrono, type_traits
`import cimple.str`	string
`import cimple.local`	locale
`import cimple.diag`	stdexcept, cassert
`import cimple.multithread`	thread, mutex, future, condition_variable, atomic
`import cimple.file`	filesystem
`import cimple.regex`	regex
`import cimple.range`	ranges
`import cimple.corot`	coroutine

Variables & Data Types

int x = 5
float pi = 3.14
string name = "Saravanan"
bool isCimpleCool = true

Printing

print("Hello,", name)

Input (C++ style)

int age
cin(age)

Arithmetic & Operators

Supports all standard operators from C++, including: + - * / %, == != > < <= >=, && || !, & | ^ ~ << >>, `= += -= *= /= %=`, ++ --

If-Else

if(x > 10):
    print("Greater")
else:
    print("Smaller or equal")
end

Loops (While & For)

// While Loop
int i = 0
while(i < 5):
    print(i)
    i++
end

// For Loop
for(int i = 0, i < 5, i++):
    print("i =", i)
end

Functions

void greet():
    print("Hello from a function!")
end

greet()

// Function with return value
int add(int a, int b):
    return a + b
end

Comments

// This is a single-line comment

/*
This is a multi-line comment
that can span multiple lines.
*/

Example Program — Factorial

print("Enter a number:")
int a
cin(a)
int fact = 1
for(int i = 1, i <= a, i++):
    fact *= i
end
print("Factorial is:", fact)

Support import logic to inject modules automatically
String manipulation utilities
Class/object support
File handling functions
Enhanced function parameters (default values, multiple returns)
Cross-platform executable packaging

We’re building a new, open-source programming language made by and for young developers and passionate learners. If you believe in the power of simplicity and performance — this is your language.
