A feline-friendly esoteric programming language

.meow — The Feline-Friendly Esoteric Programming Language

Because programming should be fun, cats are chaotic, and you deserve to write code that goes meow!

What is MeowLang?

MeowLang (.meow) is a whimsical esoteric programming language where every line of code sounds like a cat. Inspired by the chaos of esolangs and the elegance of felines, .meow lets you vibe code using cat noises.

Quick Start

Installation

# Clone the repository
git clone https://github.com/jaytirthjoshi/meow.git
cd meow

# Run a .meow program
python meow_interpreter.py examples/hello_world.meow

Your First .meow Program

Create a file called hello.meow:

# Hello World in .meow
meow
meow
meow
purr
hiss
purr
scratch
purr

Run it:

python meow_interpreter.py hello.meow

Output:

3
2
0

Commands Reference

Command	Action	Example
meow	Increment memory value by 1	meow → memory += 1
hiss	Decrement memory value by 1	hiss → memory -= 1
purr	Print the current memory value	purr → prints memory
nap	Do nothing (no-op)	nap → does nothing
scratch	Reset memory value to 0	scratch → memory = 0
lick	Double the current memory value	lick → memory *= 2
zoomies	Square the memory value	zoomies → memory = memory²
yowl	Begin a loop (while memory != 0)	yowl → loop start
paw	End a loop	paw → loop end
sleep	Sleep for memory value milliseconds	sleep → pause execution
🐾	Comment/decoration (ignored)	🐾 comment 🐾
mew	Take user input and set memory to that value	mew → memory = user input
pounce <line_number>	Jump to the specified line number (1-based)	pounce 5

File Extension

All MeowLang programs are saved as .meow files:

• hello_world.meow
• fibonacci.meow
• countdown.meow

Usage

Command Line Interface

# Run a .meow file
python meow_interpreter.py program.meow

# Execute code directly
python meow_interpreter.py -e "meow meow meow purr"

# Get help
python meow_interpreter.py

Python API

from meow_interpreter import MeowInterpreter

interpreter = MeowInterpreter()

# Run from string
code = """
meow
meow
meow
purr
"""
result = interpreter.run(code)
print(result)  # Output: 3

# Run from file
result = interpreter.run_file("program.meow")

Language Features

Memory Model

• Single integer memory cell
• Starts at 0
• Can be positive or negative
• Supports basic arithmetic operations

Control Flow

• Simple while loops with yowl and paw
• Loops continue while memory != 0
• Nested loops supported

Input/Output

• purr outputs current memory value
• Output is always numeric
• Values are printed on separate lines

Comments and Decorations

• Lines starting with 🐾 are comments
• Emoji comments (🐾 comment 🐾) are ignored
• Empty lines are skipped

Notes & Limitations

• Case-sensitive: All commands must be lowercase
• Whitespace: Commands are separated by newlines
• Unknown commands: Ignored with a warning
• Memory limits: Standard Python integer limits apply
• No input: Currently read-only (memory manipulation only)

Why .meow?

Because:

• Programming is fun — Why not make it adorable?
• Cats are chaotic — Perfect for esoteric languages
• You deserve joy — Write code that makes you smile
• Learning is better with cats — Meow while you code!

Contributing

Want to add more cat commands? Here are some ideas:

• stretch — Absolute value
• pounce — Jump to line number
• groom — Sort memory (if we add arrays)
• chase — Random number generation
• sleep — Sleep/delay command
