Google Analytics

I have used Google Analytics, so target url is this blog.

Most popular page in this blog is My open source have new features 2 in period from a day of start blog to today.

I written this page about my open source's new feature that is enable to load uv coordinate and texture file infomation from 3ds file.

Define local function in Ruby

I will write code like procedural language with Ruby ;-)

Next codes are to define local function and to call it from main function.

1. def OutputFile
2. infile = open("filename")
3. while line = infile.gets
4. print line
5. end
6. end
7. begin
8. OutputFile()
9. end

Define Class Method in Ruby

Today, I study the way to define class method in ruby.

This way help me to make tiny utility function.

Following codes are the way.

1. module MyModule
2. class Utility
3. def Utility.writingSignLine(f)
4. f.print "#"
5. for i in 0...77
6. f.print "="
7. end
8. f.print "\n"
9. end
10. end
11. end

Keynote is the 3 line.

This line expresses to define next codes as class method code.

Calling way is simple.

It's next!

1. f = open(file_name, "w")
2. MyModule::Utility::writingSignLine(f)

Good 3D Model Site

I have found a good site about 3d model.

URL is this.

There are models that are STAR WARS, Dragon Ball and so on.

Especially Darth Vador and Millenium Falcon like good model!

The way to make directory with Ruby

If I make a directory with ruby.

1. #!/usr/bin/ruby
2. begin
3. directory_name = Dir::pwd + "/" + "test"
4. if FileTest::directory?(directory_name)
5. return
6. end
7. Dir::mkdir(directory_name)
8. end

Above codes allow me to create a directory.

1 line expresses that this file is ruby process.

2 line is Main thread starting sign, 8 line is end sign.

4 line checks to exists or not.

7 line real make directory.

Long Time No See Ruby!

I studied Ruby 5 years ago.

At the time, I did know object oriented, c++, computer science.
Therefore, I did not understand good elements of Ruby.

Now, I have grown up at that time!
I see document of ruby.

I understand that ruby is good programming language!!

Ruby is ideal object oriented programming.

Next codes are that I wrote yesterday.

#!/usr/bin/ruby

=begin
  Hello !
  Tomorrow, I will install ruby-el in My laptop-machine.
=end

# define my class 
module My
  class Data
 attr_accessor :param, :index

 # This method is original method
    def output
     p @param
     p @index
    end

 # This method is constructor
 def initialize( index, param)
   @index = index
   @param = param
 end

  end
end


# Following codes main thread!
begin


data = My::Data.new(10, "Hello Ruby!!")

p data.param

end

Improve Code

Now, A part of code of my open source is dirty and likes mud.

There is dirty code in user interface.

I builded user interface with gtk+ library.

When I written my open source, I did not have so much time.

But, I improve code of user interface.

I can not join debian session

I can not finish to write a report of the software license, so I do not join debian study session.

I regret not to join this session.

vector erase

Vector in stl allow me to erase element.
This way is calling "erase" method.

Following codes are sample.

#include < iostream >
#include < vector >
using namespace std;

int main(void)
{
  vector< int > tmp;

  tmp.push_back(1);
  tmp.push_back(2);
  tmp.push_back(3);
  tmp.push_back(4);

  for( int i = 0;i < tmp.size(); i++){
 cout << tmp[i] << endl;
  }

  cout << "erase" << endl;
  vector< int >::iterator ite = tmp.begin();
  ite++;
  ite++;
  tmp.erase(ite);
  for( int i = 0;i < tmp.size(); i++){
 cout << tmp[i] << endl;
  }
  return 0;
}
