🚀 Introducing Pebble: A Tiny New Programming Language

Rasa Dariush — Mon, 15 Sep 2025 12:18:48 +0000

Hey everyone 👋

I’m super excited to announce Pebble, my own programming language — simple, fun, and beginner-friendly. I just published it to PyPI so anyone can install and try it out! 🎉

🌟 Why Pebble?

Pebble is designed to feel light and readable, kind of like Python, but with its own twist:

Friendly keywords (fnc, say, out, go, until)
Easy math and variables (x is 10)
Built-in loops, conditionals, functions
Lists and dictionaries with clean syntax
Input and output made super simple

I wanted something that feels natural, is easy to pick up, but still powerful enough to build stuff.

🛠️ Installation

Pebble is on PyPI, so you can grab it with:

pip install pebble-lang

📂 Usage

Write your Pebble code in a .pb file, then run it with:

python -m pebble yourfile.pb

✨ Example Code

say "Hello Pebble!"

x is 10

fnc double(n):
    out n * 2

say double(x)

go i in {1, 2, 3}:
    say "loop " + i

✅ Output:

Hello Pebble!
20
loop 1
loop 2
loop 3

💡 Features

say → print to screen
fnc → define functions
out → return values
go → for loops
until → while loops
inp[...] → get input
! → comments

And much more coming soon 🚀

📢 Get Involved

The project is open-source on GitHub:
👉 Pebble-lang
I’d love feedback, ideas, and contributions. This is just the beginning — Pebble will grow with the community!

🎉 I’ve Moved from `rs-calculator` to `rsc` — Here’s What’s New!

Rasa Dariush — Sat, 02 Aug 2025 11:18:11 +0000

Hey everyone! 👋

I wanted to share some exciting news about my Python calculator library. After some thought and feedback, I decided to rename and simplify the package from rs-calculator to just rsc. The goal? To make it as clean and easy to use as possible!

Why the change?

The old name rs-calculator was a bit long and sometimes confusing to type or remember. By switching to rsc, the library gets a fresh, short, and memorable name — perfect for quick imports and smoother development.

What does `rsc` offer?

If you’re new to this library, here’s a quick rundown:

🧮 Calculate expressions with ease using the calculate() function
📌 Assign variables with assign_var() and use them in calculations
🔢 Supports common operators like +, -, *, /, //, %, **, and ^
🧩 Handles parentheses for grouping complex expressions
🔒 Uses safe evaluation under the hood (with the asteval package) so you don’t have to worry about security
🎯 Simple API designed to get you calculating fast

How do you use it?

Here’s a quick example to get you started:

import rsc

print(rsc.calculate("2 + 3 * (4 - 1)"))  # Output: 11
print(rsc.calculate("5 ^ 2 + 10"))       # Output: 35

# Assign variables
rsc.assign_var("a", 10)
rsc.assign_var("b", 20)
rsc.assign_var("c", 10)

# Use variables in calculations
print(rsc.calculate("a + b - c"))        # Output: 20
print(rsc.calculate("(a + b) - c"))      # Output: 20

How to install?

Just run this in your terminal:

pip install rsc

A little about the package

I believe rsc might be the simplest calculator library in Python with variable support — perfect for beginners, students, or anyone who needs a lightweight tool for quick math.

The library is designed with simplicity and safety in mind, so you can trust it in your projects without worrying about complex setup or security risks.

Where to find it?

You can check out the project on PyPI here to see the latest versions, docs, and more.

What’s next?

I’m always open to feedback and contributions! If you have ideas or find bugs, please feel free to open an issue or submit a pull request on the GitHub repo (link in the PyPI page).

Thanks for reading, and happy calculating! ✨

🚀 RS Calculator v0.2.0: Safer, Smarter, and Now Supports Full Math Expressions!

Rasa Dariush — Fri, 01 Aug 2025 18:47:17 +0000

🚀 RS Calculator v0.2.0: Now Handles Full Expressions with Infinite Numbers, Operators, and Safety 💥

Hey Pythonistas! 👋

I’m thrilled to announce a huge upgrade to my beginner-friendly calculator library: RS Calculator v0.2.0 🎉

This version brings smarter math, safer evaluation, and a cleaner package design — all in one release!

✨ What’s New in v0.2.0?

✅ Infinite numbers and operators — write full expressions like "2 + 3 * 4 - 1 / 5 + (6 ** 2)"

✅ Parentheses and operator precedence now work correctly

✅ Secure evaluation using asteval instead of risky eval()

✅ Input validation: only math-safe characters allowed

✅ Modern packaging with pyproject.toml

✅ Clear error messages for division by zero and invalid input

📦 Installation

Install via pip:

pip install rs-calculator

pip install rs-calculator==0.2.0

🧠 How to Use

from rs_calculator import calculate, show_help

# Infinite numbers and multiple operators
print(calculate("2 + 3 * 4 - 1 / 5 + (6 ^ 2)"))  # 40.8
print(calculate("10 + 5 * 2 - 3 // 2 + (8 % 3)"))  # 20.5
print(calculate("5 ^ 2 + 10"))                    # 35

# Division by zero
print(calculate("10 / 0"))  # Error: Division by zero

# Help message
show_help()

🛡️ Safe Expression Evaluation

No risky eval() calls!
RS Calculator now uses asteval, a safe math-only interpreter that:

Only evaluates valid math expressions
Rejects anything with unsafe characters or code
Supports only: 0-9, +, -, *, x, /, //, %, **, ^, (), and whitespace

🧱 Built for Beginners

I created rs_calculator to give new Python learners a clean, fun way to explore:

Packaging a Python module
Using safe expression evaluation
Understanding how a calculator works under the hood

I Published My First Python Library: `rs-calculator`

Rasa Dariush — Sat, 26 Jul 2025 10:52:03 +0000

I just released my first Python library on PyPI — it’s called rs-calculator.

It’s not trying to be the smartest calculator out there, but it might be the simplest one.

A simple, open-source calculator library designed to help beginners both use and understand how Python libraries are built.

🔗 GitHub

https://github.com/Rasa8877/rs-calculator

📦 Install with pip

pip install rs-calculator

✨ Features

calculate() function with simple math: +, -, , /, *, %, //

show_help() that actually shows help — no extra docs needed

Handles division/modulo by zero

If you’re learning Python or teaching it, give it a try.
I’d love feedback or ideas for improvement 🙌
