Bistrot

A cli tool that transforms any Python function into an executable, or can easily print any constant in a codebase or library

It takes an existing Python function in a project and allows you to call it as an independent executable. All the function arguments become cli arguments with argparse.

Examples

Let's consider this example from examples/ops.py:

#examples/ops.py
def add(a: int, b: int) -> int:
    return a + b

We can call this function from the command line using bistrot:

$ bistrot examples.ops:add --x=2 --y=3
bistrot> 5

Or it can use positional arguments if they are defined as such in the function:

$ bistrot examples.ops:add 2 3
bistrot> 5

However, the mandatory arguments must all be either positional or named in a cli call.

It also works with static and class methods

#examples/klass.py
import bistrot

class UsefulClass:
    @staticmethod
    def version():
        return bistrot.__version__

$ bistrot examples.klass:UsefulClass.version
bistrot> 0.1.0a1

The same result can be achieved by targeting directly the __version__ variable:

$ bistrot bistrot:__version__
bistrot> 0.1.0a1

It is also possible to call methods on strings

$ bistrot '{\"hello\"}:upper'
bistrot> HELLO

Install

Bistrot is on pypi and it has no dependencies! Install it simply with

$ pip install bistrot

Or you may want to install it with pipx for global usage

$ pipx install bistrot
$ bistrot <cmds>

And verify your installation with

$ bistrot --version
bistrot> 0.1.0a1

Warning

This project is still experimental and is guaranteed to work only with primitive Python types.
