the-pyro-lang 2.0.0

A friendlier Python that compiles to Python

Pyro – A friendlier Python

Pyro is a programming language that feels like Python but removes the rough edges: no indentation errors, no self, no mandatory print() parentheses, and blocks end with end.

It compiles to standard Python – so you can use any Python library (NumPy, Django, TensorFlow) without change.

Why Pyro?

Feature	Python	Pyro
Blocks	Indentation sensitive	if ... end (no indentation errors)
Function definition	def	func (standard) or fn (Mojo-style Fast execution path!)
Method first argument	self	this (shorter)
print	print("hello")	print "hello" (or with parens)
Colons after headers	Required	Optional
Variable assignment	x = 1	make x: int = 1 or x = 1 (MyPy typing supported)
Ranges	range(1,6)	1..5 (inclusive)
Functional Pipelines	print(add(x, 10))	`x

🔥 NEW in v1.0.0 🔥

• Beginner Tracebacks: Pyret-inspired visually pinpointed (^) error handlers.
• Typing out-the-box: MyPy support for .pyro definitions.
• Mojo Speeds: fn explicitly caches and wraps using numba.njit implicitly.
• Browser Sandbox: Comes with an interactive HTML examples/browser_playground.html inspired by Brython/Skulpt.
• MCU & Web Compilation: Use --target mcu or --target js (RapydScript) for direct integrations.

Example

print "Hello from Pyro!"

make x = 10
y = 20
print "Sum: " + str(x + y)

if x > 5
    print "x is large"
else
    print "x is small"
end

func greet(name)
    print "Hello, " + name
end

greet("world")

for i in 1..5
    print i
end

class Person
    constructor(name)
        this.name = name
    end
    func say_hello()
        print "My name is " + this.name
    end
end

p = Person("Pyro")
p.say_hello()

Installation

To install Pyro globally or to update to the latest v1.0.0 release:

pip install --upgrade the-pyro-lang==1.0.0

Usage

Compile a .pyro file to Python:

pyro compile input.pyro -o output.py

Run directly:

pyro run input.pyro

Or use as a Python module:

from pyro import compile_pyro
py_code = compile_pyro(source)
exec(py_code)

Roadmap

• MVP (variables, arithmetic, if/else, loops, functions, classes)

• Compile to Python source

• Import system

• Exception handling (try/catch)

• List/dict comprehensions

• Standalone bytecode compiler (direct .pyc output)

• Self‑hosting (compiler written in Pyro itself)
