CPP File To HTML

Recently, I written converter program with ruby, It is enable to convert a source file of c plus plus to html format.

The converter program can change tab space to span tag of html, and color keywords.
Color of keywords is blue.

Next code is converter program.

#!/usr/bin/ruby

def convertKeyWords(arg)

if(arg =~ /(<)/ ) then

arg.gsub!($1, "<")

end

if(arg =~ /(>)/ ) then

arg.gsub!($1, ">")

end

if( arg =~ /(if)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(typedef)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(class)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(using namespace)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(while)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(for)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(void)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(int)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(double)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(char)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(#include)/ ) then

arg.gsub!($1, "" + $1 + "")

end

if(arg =~ /(\/\/.*)/ ) then

arg.gsub!($1, "" + $1 + "")

end

arg

end

begin

if( ARGV[0] == nil ) then

puts " Usage: cpp2html.rb sourcefile"

puts " Sourcefile must be cplusplus source file."

exit(1);

end

puts "<HTML>\n<HEAD>\n<TITLE>\n" + ARGV[0]+ "\n</TITLE>\n</HEAD>\n"

unless FileTest::file?(ARGV[0]) then

puts "not file"

end

sourcefile = File.new(ARGV[0]);

comment_count = 0

indent_count = 0;

while line = sourcefile.gets()

if (/^=begin/ =~ line) then

comment_count = 1;

next

end

if (/^=end/ =~ line) then

comment_count = 0;

next

end

next if (comment_count == 1 )

line = line.chop

next if( line.empty? )

# count indent

# Following code is error! ToDo

indent_count -= 1 if ( /\}s*$/ =~ line )

# convert from tab to style

tmp = ""

for i in 0...indent_count

tmp += ""

end

# count indent

indent_count += 1 if ( /\s*\{/ =~ line )

# converting

# check key wards

line = convertKeyWords(line)

line.gsub!(/^\s+/, tmp)

line += " \n"

puts line

end

puts "</HTML>"

end

Default Argument

When I write define of function or method with C++, I always write next code.


namespace my{
 enum Type{
  NONE = 0x00,
  SCALAR = 0x01,
  VECTOR = 0x03,
 };
 void function(double* , Type type = NONE);
}

I want that user of my function understand the function more easily than next code.


namespace my{
 enum Type{
  NONE = 0x00,
  SCALAR = 0x01,
  VECTOR = 0x03,
 };
 void function(double* , Type type);
 void function(double*);
}

Above code is the same as before function used default argument.

Using Default argument, Code line decreases.

Message Box With Gtk

I want a simple function showing Message box in gtk like Windows'API.
Therefore I make next code.


/**
 * This method's work is like Windows' MessageBox
 * @date 2009-1-10
 * @version 1.0
 */
bool ShowMessageBox(std::string title, std::string message)
{
  GlobalParameter* gp = GlobalParameter::getInstance();
  GtkDialogFlags flag=(GtkDialogFlags(GTK_DIALOG_MODAL|GTK_DIALOG_DESTROY_WITH_PARENT);
  GtkWidget* dialog = gtk_dialog_new_with_buttons(title.c_str(),GTK_WINDOW(gp->getM_main_window()),flag,NULL);
  GtkWidget* label = gtk_label_new(message.c_str());
  gtk_container_add(GTK_CONTAINER(GTK_DIALOG(dialog)->vbox),label);
  gtk_widget_show_all(dialog);
  gint response = gtk_dialog_run(GTK_DIALOG(dialog));
  return true;
}

I wait for the news Google ship Google Chrome on Linux.
Now, I use FireFox3.0.5 on Ubuntu8.04.

Since Firefox is good application, I have no dissatisfaction in Firefox.

But, I like new goods and Google!
I would like to use Google Chrome, but I don't use WindowsXP or Windows Vista.
