Angular2 + JSPM cheat sheet

First time setup

• install jspm beta: npm install -g jspm@beta
• set up your project: jspm init
• install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

 * One example of using react-motion (0.3.0) within react-router (v1.0.0-rc3).

 * Usage is simple, and really only requires two things–both of which are

 *
 *   <RouteTransition pathname={this.props.pathname}>

tracked

@tracked is a decorator for Preact that makes working with state values no different than properties on your component instance.

It's one 300 byte function that creates a getter/setter alias into state/setState() for a given key, with an optional initial value. The "magic" here is simply that it works as a property decorator rather than a function, so it appears to integrate directly into the language.

tracked has no dependencies and works with any component implementation that uses this.state and this.setState().

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

// TransientFuction: A light-weight alternative to std::function [C++11]
// Pass any callback - including capturing lambdas - cheaply and quickly as a 
// function argument
// 
// Based on: 
// https://deplinenoise.wordpress.com/2014/02/23/using-c11-capturing-lambdas-w-vanilla-c-api-functions/
//
//  - No instantiation of called function at each call site
//  - Simple to use - use TransientFunction<> as the function argument
//  - Low cost: cheap setup, one indirect function call to invoke
