Elixir Debugging Techniques

IO

Old standby for a quick look into your code

IO.puts

Works with anything that implements the String.Chars protocol, AKA the to_string method. Elixir ships with: https://github.com/elixir-lang/elixir/blob/e769afbed96b6b9eee6a4f4ac4a6ea00bc0630f7/lib/elixir/lib/string/chars.ex

IO.inspect

Returns the term handed to it untouched so you can plop it straight in your code

Preface

So in the past, I've used MAMP/MAMP Pro apps and others alike. I've also, setup my own local MAMP stack with homebrew, that used dnsmasq to dynamically add vhosts anytime I added a new folder to the Sites folder which made it very convenient. But, then I started running into other environment issues with PHP versions on remote machines/servers not being updated or some other crazy thingamabob breaking. I researched and invested time in Vagrant, but that seem to break more often than my homebrew setup. So I researched again investing time into Docker via Docker for Mac (which is BAMF), which I'm sold on and use daily, but it still seems a little bleeding edge and not so simple to wrap your head around the concept. Not to mention I don't have a real use case to play with and take advantage of all the features that come packed with Docker.

This is the beginning of trying to find something more simple, and slightly quicker to setup.

When a beginner asks you "when do I use semi-colons?" would you rather say this?

// what people who say "use semicolons!!" say
class Foo {
  prop = {
  }; // yes

Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Syntax and core concepts

Basic Syntax

Single-line comments are started with //. Multi-line comments are started with /* and ended with */.
C# uses braces ({ and }) instead of indentation to organize code into blocks. If a block is a single line, the braces can be omitted. For example,

başlangıç

yeni bir oturum başlatmak

tmux new -s oturum_adi

açılan oturumu "detach" etmek.

	# Sample Nginx config with sane caching settings for modern web development
	#
	# Motivation:
	# Modern web development often happens with developer tools open, e. g. the Chrome Dev Tools.
	# These tools automatically deactivate all sorts of caching for you, so you always have a fresh
	# and juicy version of your assets available.
	# At some point, however, you want to show your work to testers, your boss or your client.
	# After you implemented and deployed their feedback, they reload the testing page – and report
	# the exact same issues as before! What happened? Of course, they did not have developer tools
	# open, and of course, they did not empty their caches before navigating to your site.

	// Get an array of all files in a directory.
	$files = File::files('path_to_dir');

	// Get all of the files from the given directory (recursive).
	$files = File::allFiles('path_to_dir');

	// Get all of the directories within a given directory.
	$files = File::directory('path_to_dir');
