About viper_:

The goal of is to leverage as many C++ language features as possible to replicate the clean syntax and dynamic typing of python.

This project isn't designed to be used seriously but instead as a fun demonstration of some of the useful, interesting, and obscure features C++ has to offer.

viper_.h is the single include header file that requires no setup but can be configured with the preprocessor.

Features:

Variables can be declared without explicit types, named with a literal and an underscore:

"my_variable"_ = 100;
// Also supports other literals:
123_ = "Hello, World!";
3.14_ = 123_; // 3.14 = "Hello, World!"

Variables can be easily printed with print():

print("{123} This is a format print so my_variable = {my_variable}. Cool, right?");

Hello, World! This is a format print so my_variable = 100. Cool, right?

Variables can optionally be given a type hint for type safety with _(Type):

"hinted"_ _(int) = 100; // Okay
"bad_hint"_ _(int) = "100"; // Throws a type error

Comparison:

viper_:

int main() {
    "my_variable"_ = 100;
    // Also supports other literals:
    123_ = "Hello, World!";
    3.14_ = 123_; // 3.14 = "Hello, World!"
    print("{123} This is a format print so my_variable = {my_variable}. Cool, right?");
    "hinted"_ _(int) = 100; // Okay
    "bad_hint"_ _(int) = "100"; // Throws a type error
}

Python:

my_variable = 100
# Doesn't support variable names beginning with numbers or containing '.'
var123 = "Hello, World!"
var3_14 = var123 # var3_14 = "Hello, World!"
print(f"{var123} This is a format print so my_variable = {my_variable}. Cool, right?")
hinted : int = 100 # Okay
bad_hint : int = "100" # No error but could be caught by a static analyzer
