Hello World orientado a objetos

Em C++

$ gvim helloWorld.cpp

 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4 
 5 class HelloWorld{
 6 
 7 public:
 8         // construtor!
 9         HelloWorld(string mensagem) {
10                 this->_mensagem = mensagem;
11         }
12 
13         // metodo show
14         void show() const {
15                 cout << "mensagem: "
16                      << this->_mensagem
17                      << endl;
18         }

24 int main()
25 {
26         HelloWorld obj ("ola mundo");
27         obj.show();
28 
29         return 0;
30 }

Compilando:

$ make helloWorld

Em Vim Script

Usando:

$ cat usaHelloWorld.vim
let obj = helloWorld#New("Hello World")

echo "mensagem:" obj.message
echo "obj.Get:" | call obj.Get()
call obj.Set ("Ola Mundo!")
echo "obj.Get:" | call obj.Get()

Rename files with the command interpreter sh

sh is the standard command interpreter for the system.

ifi - input + filter + interpreter

Step 1:

$ ls Run*
Run this to install syntax and clip files for jEdit.ahk
Run this to install syntax and clip files for PSPad.ahk
Run this to install syntax and clip library files for TextPad.ahk
Run this to install syntax and cliptext files for EditPlus.ahk
Run this to install syntax file for MED.ahk
Run this to install syntax file for Notepad++.ahk
Run this to install syntax highlighting for ConTEXT.ahk
Run this to install syntax highlighting for UltraEdit.ahk

Step 2:

$ ls Run*| sed -r 's/.* (.*.ahk)/& => \1/'
Run this to install syntax and clip files for jEdit.ahk => jEdit.ahk
Run this to install syntax and clip files for PSPad.ahk => PSPad.ahk
Run this to install syntax and clip library files for TextPad.ahk => TextPad.ahk
Run this to install syntax and cliptext files for EditPlus.ahk => EditPlus.ahk
Run this to install syntax file for MED.ahk => MED.ahk
Run this to install syntax file for Notepad++.ahk => Notepad++.ahk
Run this to install syntax highlighting for ConTEXT.ahk => ConTEXT.ahk
Run this to install syntax highlighting for UltraEdit.ahk => UltraEdit.ahk

Step 3:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv & \1/'
mv Run this to install syntax and clip files for jEdit.ahk jEdit.ahk
mv Run this to install syntax and clip files for PSPad.ahk PSPad.ahk
mv Run this to install syntax and clip library files for TextPad.ahk TextPad.ahk
mv Run this to install syntax and cliptext files for EditPlus.ahk EditPlus.ahk
mv Run this to install syntax file for MED.ahk MED.ahk
mv Run this to install syntax file for Notepad++.ahk Notepad++.ahk
mv Run this to install syntax highlighting for ConTEXT.ahk ConTEXT.ahk
mv Run this to install syntax highlighting for UltraEdit.ahk UltraEdit.ahk

Step 4:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv "&" \1/'
mv "Run this to install syntax and clip files for jEdit.ahk" jEdit.ahk
mv "Run this to install syntax and clip files for PSPad.ahk" PSPad.ahk
mv "Run this to install syntax and clip library files for TextPad.ahk" TextPad.ahk
mv "Run this to install syntax and cliptext files for EditPlus.ahk" EditPlus.ahk
mv "Run this to install syntax file for MED.ahk" MED.ahk
mv "Run this to install syntax file for Notepad++.ahk" Notepad++.ahk
mv "Run this to install syntax highlighting for ConTEXT.ahk" ConTEXT.ahk
mv "Run this to install syntax highlighting for UltraEdit.ahk" UltraEdit.ahk

Step 5:

$ ls Run*| sed -r 's/.* (.*.ahk)/mv "&" \1/'| sh

Other example: .texi -> .CCCAA

$ ls *.texi| sed 's/.*/ mv & `basename & .texi`.CCCAA/'|sh

Passando variáveis para o sed.

Para usar variáveis no sed nao use ' aspas simples, apenas " aspas dupals
veja os exeplos:

exemplo 01:

$ var=value
$ echo TEXT| sed "s/T/$var/"
valueEXT

exemplo 02:

$ var=T
$ echo TEXT| sed "s/$var/V/g"
VEXV

The Human Element

For each of us,
there is a moment of discovery.
We turn a page,
we raise a hand.
And just then, in the flash of a synapse,
we learn that life is elemental.
And this knowledge changes everything.
We look around and see the grandness of the scheme.
Sodium bonding with chlorine,
carbon bonding with oxygen,
hydrogen bonding with oxygen.
We see all things connected.
We see life unfold.
And in the dazzling brilliance of this knowledge,
we may overlook the element not listed on the chart.
Its importance so obvious,
its presence is simply understood.
The missing element
is the human element.
And when we add it to the equation,
the chemistry changes.
Every reaction is different.
Potassium looks to bond with potential.
Metals behave with hardened resolve.
And hydrogen and oxygen form desire.
The human element
is the element of change.
It gives us our footing to stand fearlessly
and face the future.
It is a way of seeing
that gives us a way of touching.
Issues,
ambitions,
lives.
The human element.
Nothing is more fundamental.
Nothing more elemental.

What is a journey?
A journey is not a trip.
It's not a vacation.
It's a process. A discovery.
It's a process of self-discovery.
A journey brings us face to face with ourselves.
A journey shows us not only the world,
but how we fit in it.
Does the person create the journey
or does the journey create the person?
The journey is life itself.
Where will life take you?
