Emoticon Programming

In honor of today's bright day I publish this article. After all, you also sometimes think that the code consists of emoticons?

Ruby

Determination of the default or facial expression lips:

foo ||= [] foo ||= {} foo ||= '' foo ||= 0 

Jumping toads out of the wash out heme:

 def_delegators :@config, :[], :[]=, :sort 

')
From there, code generation, cyclo eats a variable:

 @#{sym} 

Calling the class as a hash or array, again a toad:

 alias_method :regular_writer, :[]= unless method_defined?(:regular_writer) 

govnokod.ru/2749

 map(&:-@) 

Seem to be?


Toad with turban in the ternary operator.

 var.is_a Array ? {} : [] 

Another Ruby monster, applying the 'or' and 'and' operator to all elements of the flags with the help of poker face and lip rolling.

 flags.reduce(&:|) flags.reduce(&:&) 

We need to make a terrible face if we are not sure that the hash has an embedded hash:

 session[:comments].try(:[], @comment.id) 

bash

Command line parameters also completely disappear for smiles:

Every time it seems to me that this is such a wide apologetic smile, saying “I forgot what tasks there are, please bring out the list”:

 rake -D 

CoffeeScript

Complete panic when mixing Coffee and jQuery

 $(@) 

CoffeeScript makes smiles easy

 foo = bar getBar:-> @bar #    Coffee not:(o)-> !o 

Slim

 =< "Hello!" => "Hello!" =<> "Hello!" 

Php

It's sad when the array ends:

 $var = array( 1 => 'one' ); 

And even sadder when it ends with the transfer of attributes:

 $var = some_function(array( 'named_attr' => 'one' )); 

Everywhere and everywhere

There are many places where you can pass an empty string to a function:

 ('') ("") [''] [""] 

With this you can dream up, but when this came across, it was quickly recognized as a Papuan priest (because with a native belt at the waist):

 ('.') 

And here is a sleeping owl:

 [","] 

Skype, by the way, sometimes sees smilies too. Log forwarding:

PS

Send your pieces of code in the comments, I hope, today we will put together a nice collection.

upd:

Apparently, on this holiday thoughts converge:
Factorial on Church numbers - now in emoticons
