bython-prushton 1.1.5

Transpiles Bython to Python

Bython

Python with braces. Because Python is awesome, but whitespace is awful.

Bython is a Python preprosessor which translates curly braces into indentation.

Key features

• Write Python using braces instead of whitespace, and use the transpiler to convert it to valid Python code
  • Transpiles curly braces while keeping maps, fstrings, and curlies inside strings intact
• Allows for translation of && and || to and and or
• Can optionally translate true and false to True and False

Code example

myMap = {
    "status": "awesome!"
}

def print_message(num_of_times) {
    for i in range(num_of_times) {
        print(f"Bython is {myMap["status"]}");
    }
}

if __name__ == "__main__" {
    print_message(10);
}

Installation

Install from pip

$ python -m pip install bython-prushton

Quick intro

Bython works by first translating Bython-files (required file ending: .by) into Python-files, and then using Python to run them. You therefore need a working installation of Python for Bython to work.

To run a Bython program, simply type

$ python -m bython-prushton source.by 

to run source.by. If you want more details on how to run Bython files (flags, etc), type

$ python -m bython-prushton -h

To transpile an entire directory, run bython with the -o to specify the output directory, and -e to specify the entry point.

$ python -m bython-prushton -o dist -e main.py src

To transpile without running, omit the -e argument. You can also include -t to translate lowercase booleans to uppercase and null to None

$ python -m bython-prushton -o dist -t src

Contributing

Code

If you want to contribute, make sure to install

• Python
• Colorama

All source code is located in src

• src/bython.py handles the command line arguments
• src/parser.py handles tokenizing and parsing files
• src/py2by.py parses python to bython and could use some help

testcases only test bython conversions, and are structured as follows:

<test name>
|-main.by Bython code to convert
|-expected_out.txt Expected out when running the bython
|-build/ Dir for transpiled python code

run make test to run bython tests

Installation

If you want to write an install recipe for windows or mac, please feel free. I cannot write these scripts myself as I have neither.
