Bootstrap for the Dart language is looking not only for contributors, but also new maintainers!

The current state of the project takes the JavaScript version of bootstrap and uses a transformer to allow the API to be used in a Dart context.

Effortless React State Management.

Alfa - Effortless React State Management

Why Alfa?

React is an excellent library for creating interactive and stateful views. However, things become unclear when you need to share & change data across components.

Alfa is an intuitive and straightforward way to manage React state. It completely decouples the complex relationships between components and let you focus on making components that work anywhere.

Its simple design allows you to adopt it in a matter of minutes while at the same time provides your essential tools to keep your application code easy to change and understand. Here is a list of things why it is the perfect fit for your next React app:

  • Easy - Only 4 functions/APIs to learn.
  • Fast - Alfa wraps your components with a thin layer. It introduces a little or no performance impacts.
  • Small - ~ 190LOC & 3KB minified + gzipped.
  • Async - Alfa supports asynchronous operation natively without additional packages.
  • Explicit - Alfa lets you know what a component requires (input) and what it changes (output).
  • Transparent - You can use and unit test your components as it is without Alfa. Users of your lib/component could but don't have to use Alfa at all.
  • React Native - Support React Native out of the box.
  • Server Render - Support isomorphic app out of the box.
  • Production Ready - 100% test coverage and being used in productions.


Quick Guide


Use npm to add it to your package.json.

npm install --save alfa

Alternatively, use yarn if you prefer:

yarn add alfa

Getting Data for Components

Alfa converts your regular React component into a dependency injected component by injecting application data from a key/value store. Let Alfa handle the data if you use it in different components:

// hello.js
import React from 'react'
import { subscribe } from 'alfa'

// A stateless functional component.
function HelloMessage(props) {
  // Data is injected as the property of props.
  return <div>Hello ${}!</div>

export default subscribe(HelloMessage, ['name'])

subscribe makes a new component which gets the variable name and feeds it into the HelloMessage as on (re)rendering.

Now let's see how to use the above component in our app:

// index.js
import React from 'react'
import { render } from 'react-dom'
import { provide, subscribe } from 'alfa'

import HelloMessage from './hello.js'

// Define the root app which renders HelloMessage as a child.
const App = () => (
    <HelloMessage />

// Create the Root component by wrapping the App component with initial data
// using `provide(Component, data)`.
const Root = provide(App, { name: 'Motoko' })

// Render it!
render(<Root />, document.getElementById('root'))

You don't need to pass the variable name to HelloMessage as alfa gets it from the store and pass it to HelloMessage component automatically. It allows us to quickly move the component around without worrying about how to get the data it depends on.

Changing Data

The simplest way to modify the data of the Alfa store is to inject the built-in set function to the component.

// change.js
import { subscribe } from 'alfa'
import React, { Component } from 'react'

// A stateful class component.
class ChangeName extends Component {
  handleChange = event => {
    // Calling `set('mykey', 'my value')` will change the data `mykey`
    // in store to value `my value`.

  handleSubmit = event => {

  render() {
    return (
      <form onSubmit={this.handleSubmit}>

export default subscribe(ChangeName, ['set', 'name'], ['name'])

As mentioned earlier Alfa makes things explicit. So we need to define the output (the 3rd argument when calling function subscribe) of the component explicitly if we want to change a value of a key in the data store. Otherwise, Alfa complains we are trying to use set without defining the correct output.

Now add the ChangeName component to App and your index.js ends up like this:

// index.js
import React from 'react'
import { render } from 'react-dom'
import { Provider, subscribe } from 'alfa'

import HelloMessage from './hello.js'

const App = () => (
    <HelloMessage />
    <ChangeName />

// Alternatively, you can use Provider - the declarative interface of the
// provide function.
  <Provider data={{ name: 'Motoko' }}>
    <App />

Now each time you make a change in the input box React will rerender both HellowMessage and ChangeName components to reflect the change.

You can find the finished version of the above example in the folder examples/hello.

Please check documentation for API and advanced usages.

Euphoria is an interpreted language with a C backend and Euphoria frontend (so it's mostly self-hosted). The Euphoria interpreter is very fast and uses reference-counting dynamic memory management. Euphoria uses only two types: atom for storing numbers and sequence for storing dynamic arrays and strings.


We could really use a few people with any of the following skills:

  • C development in general
  • Compiler and interpreter design
  • Cross-platform build systems (make, autotools, etc.)
  • Linux software packaging (dpkg/rpm, private repos, etc.)
  • MacOS development in general
  • Learn Euphoria and use it for your projects!

Anyone who's interested, please check us out and join the discussion on our forum. If you sign up, please send an email to with the subject "all_admins email verification" so we can activate your account. (Sorry for that, but we contended with some bad actors recently so this policy is in effect for a while.)

MousePaw Media is looking for C++ and Python developers who are interested in working on unusual, cutting-edge libraries, tools, and games.

Current Projects

Here's a look at a few of our current projects:

PawLIB 1.1: High-performance, memory efficient containers and utilities for the C++ language. We're expanding our testing library (Goldilocks), improving and expanding our data structures (Flex), making message output a delight again (IOChannel), and building a tool for streamlining the design of CLI interfaces (Blueshell).

Right now, we're working on iterators for the Flex data structures, adding a new high-performance, doubly-linked list implementation, and building our collection of sorting algorithms.

Omission is a game written in Python 3. It currently uses the Kivy GUI toolkit, but needs to be re-implemented in Qt5 (PySide2).

DiamondQuest is a brand new Python 3 game, which will use the Qt5 (PySide2) GUI toolkit. We're especially needing someone with pixel-art skills to create the retro-style graphics.

Ratscript: A brand new language which seeks to combine an innovative, obvious syntax with a powerful combination of paradigms. Ratscript is being designed specifically for the next generation of game development. Takes cues from Python and Rust, among others.

Anari: A vector-based animation engine implemented in C++, allowing for memory-efficient interactive animations to be deployed onto old and new hardware alike.

Infiltrator is an upcoming Python 3 party game. We have an earlier version implemented in C++, but we want to recreate it in Python3 and Qt5 (PySide2).

Our Stack

  • C++14 (C++17 proposed)
  • Compilers: Clang and GCC
  • CMake
  • Python 3
  • Qt 5/PySide 2
  • CPGF
  • Eigen
  • Git
  • Phabricator

Getting Involved

See something you like? Jump right in! We have a robust development platform, centered around a carefully-honed Phabricator instance.

For more information, visit or contact developers (at) mousepawmedia (dot) com. You can also ask questions and join the discussion us on the Lobby chatroom on our Phabricator.

Masonite is looking for new community members. We're a rapidly growing Python web framework. Here is some recent feedback:

"I've never written any laravel (PHP makes me shudder), but I've been doing ruby and rails for about 5 years now, and this is the first python framework that's made any sense from that perspective."

"I checked out Masonite yesterday, and I ported my Flask app over in under 30 min. It took me 6 hours of figuring out how to get my flask set up and refactor it to get to a production level."

I recently created Dj-Models, which allows anyone to use the Django ORM in any sync Python web framework.

The project is a fork of Django, with all the irrelevant parts removed.


  • Mix and match your favorite web tools e.g (Dj-Models + Flask + React)
  • Minimal configuration
  • All the great features of Django's Models:
    • Schema migrations
    • Declaritive models.
    • Beautiful Query API


This project is not ready for prime time. Currently the only blocker is teaching DJ-Models where migration files should live.

Hi !

I have started working on a programming language named Kafe a while ago, and I am searching for someone (or sometwo, somethree... you get the joke :p ) to help me in this project.

What is it ? a scripting language for video games.

Basically, a programmer will have to follow those steps to use Kafe code in his game/project :

  • code something in Kafe
  • compile it using kafec (the kafe code compiler)
  • add the generated bytecode file to his project
  • #include<kafe/vm/VM.hpp>, then create his/her Kafe VM, feed it with the filename of the bytecode file, and then execute it !

Syntax examples and goals

cls Character
    dyn name
    dyn life
    dyn weapon

    # comma in argument list is optional
    fun __init__(self name life) = name = life

    fun __add__(self other) += = 0


cst default_life = 110

dyn harry_potter = new Character("Harry Potter" default_life)
dyn voldemort = new Character("Voldemort" default_life)

# let's say this is to attack voldemort
# some kind of syntaxic sugar, somehow
harry_potter + voldemort

My ultimate (unachievable) goal is to replace Lua, because it lacks proper classes and arrays (imo).

A most affordable goal would be to be able to use Kafe with a minimal performances loss in video games.

Can we compile Kafe code without using kafec ?

No, we can't. The goal is to provide only the bytecode files because they are smaller, and it's a huge performance improvement for your game/project, since it's already compiled and you don't have to wait for it to be compiled before executing Kafe code.

How is the project structured ?

It is split in 7 or 8 projects :


  • the Kafe VM
  • the Kafe compiler using ANTLR
  • the plug-ins system (I will explain how it works below)
  • the Kafe (assembler) disassembler, to be able to read bytecode more easily. It will probably be helpful to compile "text bytecode" to bytecode (as nasm does for example)
  • cup, the package manager, to download plugins


  • the website of the project, hosting the documentation
  • the KEP (Kafe Enhancement Proposals, yes my imagination is very limited), similar to the PEP of Python part of the website :


  • the tests suite (linked to cmake) for the VM, can easily be adapted for the compiler

The plug-ins

A plug-in must follow a specific pattern to be used by the Kafe VM, because it will compiled into a .dll/.so, and loaded at runtime by the VM. It will only have a 3 functions :

  • KafeVMversionRequired, to know the version of the VM used to create the plugin
  • PluginVersion, useful for debugging, and version tracking in the package manager cup
  • registerFunctionsAndObjects, to load C++ functions and Kafe classes definitions into the VM, to use them in Kafe code

Current progress

  • the website is done, just a bit empty
  • all the documentations are set up, I just need to complete them
  • I fixed a template for the KEP (to be able to convert them from Markdown to HTML for the website)
  • the Kafe Compiler is using ANTLR, so I just need a grammar (already have one, but I need to rewrite it), and a visitor (not done). The parser and lexer are done as well as the CLI
  • the Kafe VM is done by 90%. I still a bunch of things to do with the classes and plugins but I described everything in a book (I was on holydays the past 2 weeks)
  • I have templates for cup, Kafe ASM (the (assembler) disassembler), and the plugin-system (I already have something to load .dll/.so/.dynlib but I did not push it yet)
  • I also started a Kafe CLI, to be able to rule them all use cup/kafec/Kafe VM/Kafe ASM with only one program

You can join the project on Discord and/or follow it on GitHub !

past month I've been creating Angular 6 File Manager (FM) compoment. Right now I'm looking for users / testers / contributors.

Why would you want to use it?
At time I did reasearch there wasn't many components like this one, especially in Angular 6. We needed many features in only one component with almost 0 setup.

FM is themeable, customizable, translatable, supporting drag and drop file uploads. All you need to do is put some config and connect it with your backend.

Any help is welcome!
