depsolve 0.1.0

Agnostic dependencies solver

DepSolve

This is an asyncio agnostic dependency tree solver

The idea is to take out the problem of depencies solving from packages managers or importers

Usage

import asyncio
from depsolve import Dependency, walk


async def perform_importation(dependency: Dependency):
    # here your package/whatever is supposed to inherit from `Dependency`
    # if any other argument is need for the command line in the package
    # have a look to functools.partial()
    await asyncio.sleep(2)


async def main():
    dependencies = [
        Dependency(name='land'),
        Dependency(name='hen', depends_on=['land']),
        Dependency(name='eggs', depends_on=['hen']),
        Dependency(name='sugar_cane', depends_on=['land']),
        Dependency(name='plain flour', depends_on=['wheat']),
        Dependency(name='sugar', depends_on=['sugar_cane']),
        Dependency(name='genoise', depends_on=['eggs', 'sugar']),
        Dependency(name='strawberry', depends_on=['land']),
        Dependency(name='wheat', depends_on=['land']),
        Dependency(name='sirop', depends_on=['strawberry']),
        Dependency(name='cake', depends_on=['genoise', 'strawberry', 'sirop']),
        Dependency(name='cooking', depends_on=['cake'])
    ]
    async for items in walk(dependencies):
        deps_names = [dep.name for dep in items]
        print(f'dependencies to install: {len(items)} : {", ".join(deps_names)}')
        tasks = asyncio.gather(*[perform_importation(dep) for dep in items])
        await tasks


if __name__ == "__main__":
    asyncio.run(main())

wich output:

dependencies to install: 1 : land
dependencies to install: 4 : hen, sugar_cane, strawberry, wheat
dependencies to install: 4 : eggs, plain flour, sugar, sirop
dependencies to install: 1 : genoise
dependencies to install: 1 : cake
dependencies to install: 1 : cooking
