Ididi, dependency injection, in a single line of code

Ididi is a pythonic dependency injection lib, with ergonomic apis, without boilplate code, works out of the box.

# What My Project Does

it builds a dependency graph based on your type hints, and inject those dependencies into corresponding classes/functions.

In the base case, all you need to do is to make a call to instance = ididi.solve(class) and you are done.

# Quick Start

Here’s a quick example of how idid works:

import ididi

class Config:
def init(self, env: str = "prod"):
self.env = env

class Database:
def init(self, config: Config):
self.config = config

class UserRepository:
def init(self, db: Database):
self.db = db

class UserService:
def init(self, repo: UserRepository):

pipe-operator: Elixir's pipe operator in Python

TLDR: pipe-operator is an open-source python package which brings similar features to elixir's |> tap then to Python, with 2 vastly different implementations. Because why not :D

\---

Hey there! Thought it might be of interest to some of you! I come from Python but lately I've been working with Elixir (mostly at work) and came to really enjoy its pipe operator |> and its related features like tap, then, and shortcut syntaxes. So I thought to myself: "could be fun to bring this to python". So I did, and the **pipe-operator** project was born.

# What My Project Does

It provides similar features to elixir |>, allowing you to chain operations without using intermediary variables. Through 2 very different implementations, you can pass the result of the previous expression as the first parameter of the next one.

As for those 2 very different implementation, they are:

A pythonic class-based one, which is fully compatible with linters and type-checkers
And an elixir-like one, with a syntax resembling elixir's, which will drive you linters mad

# Target Audience

I don't think anyone would be using this in production/work projects, but it can be a fun tool for developers' side projects who enjoy functional programming.

# Quick demo

Python implementation:
