Declo

pip install git+https://github.com/arunpatro/declo

Declo is a Python dialect that brings JavaScript-like functional programming patterns to Python, making functional code more concise and readable.

Why?

I wanted to bring the excellent ergonomics of map, filter, chaining of functional transformations to python. We already have that in pandas, torch, so why not extend this to the rest of the language?

Usage

1. Compile Declo code to Python

# File: list_comp.declo
nums = [1, 2, 3, 4, 5]
squares = nums.map(x => x * x)
evens = nums.filter(x => x % 2 == 0)

declo compile list_comp.declo

# File: list_comp.py
nums = [1, 2, 3, 4, 5]
squares = [x * x for x in nums]
evens = [x for x in nums if x % 2 == 0]

2. Decompile

declo decompile list_comp.py

3. Run

declo run input_file.declo
declo run input_file.py
