A list of basic text formatting commands in Vim:

• = is an operator that formats/indents text.
• i{ is a text object that specifies the surrounding code block. It should be used together with v, =, etc.

Some basic but useful operation that are combination of the two basic ones above:

• vi{ visually selects the inner code block around the cursor.
• =i{ formats the code block.
• =2i{ formats the current block and the block around it.
• == formats current line.

The method to format a block of C/C++ or Java code:

• First, go to the start point of codes to be formatted, then press v to start selection.
• Second, go to the end point.
• Third, press = to format the codes that have been selected. All braces and indentations will be aligned.

A short way to format the whole buffer:

This is the C programming styles that I follows:

1. For each source file (*.c), there is a header file (*.h) that have the same name with it as it’s interface.

2. The header file starts with

#ifndef _HEADER_NAME_H
#  define  _HEADER_NAME_H

And end with:

#endif // _HEADER_NAME_H

3. #include is only used in source file usually. ONLY when it is really necessary, #include can be used in header file.

4. There is NO definition in header file.

5. Global variable defined in source file that is visible outside the module is declared as extern variable in the relevant header file. Global variable is used only when it is really necessary.

An example that follow this style is mrcc.

But unfortunately, WordPress doesn’t provide a simple way to put several pages and put some part like the widget into it. So I write some php script that will call WordPress’s API to put them input pages.

The page template is like this. This template enable the theme and load the common files that contains WordPress’s API functions. Then it generate the header, sidebar and the footer. What we need to do is add the content to replace “TODO: content here” now.

<?php
/**
* Loads the WordPress environment and template.
*/
define('WP_USE_THEMES', true);
if ( !isset($wp_did_header) ) {
  $wp_did_header = true;
  require_once( dirname(__FILE__) . '/../wp-load.php' );
}
?>

<?php get_header(); ?>
<div id="container">
  TODO: Content here.
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

1. Categories

The code for categories is:

<div>
<h1><?php _e('Categories', 'default'); ?></h1>
<div>
<ul>
  <?php wp_list_categories('title_li=&show_count=1'); ?>
</ul>
</div>
</div>

wp_list_categories() can list all the categories as a list. “show_count=1″ means the post number under each category will be shown after the category.

2. Archives

The code is:

<div>
<h1><?php _e('Archives by Month', 'default'); ?></h1>
<div>
<ul>
  <?php wp_get_archives('type=monthly&show_post_count=1'); ?>
</ul>
</div>
</div>

wp_get_archives() will show the archives. the type can be changed to weekly, daily to show archives by week or day.

3. All posts

The code:

<div>
<h1><?php _e('All posts', 'default'); ?></h1>
<div>
<ul>
<?php
  //The Query
  query_posts('posts_per_page=1000');
  //The Loop
  if ( have_posts() )
  {
    while ( have_posts() )
    {
      the_post();
?>
<li>
<a href="<?php the_permalink() ?>" rel="bookmark"
title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_title(); ?></a></li>
<?php
_e('</li>');
    }
  }
  //Reset Query
  wp_reset_query();
?>
</ul>
</div>
</div>

At most 1000 posts’ titles will be listed.

Put these php files into the site, edit the theme files and then enjoy it! :)

For debugging, I use gdb. But I use the front end cgdb. I can see the codes with the cursor when debugging. I can use F8 for next instead of n + enter. And F10 for step instead of s + enter. i is the key for enter gdb command mode. And ESC can change the user to command mode. But ESC is too far away from my finger, so I prefer “Ctrl + [” to ESC ;)

My configuration files can be found here if they are useful for someone:
http://github.com/zma/config_files

In the config file of cgdb:
“set winsplit=top_big: is for letting the code window bigger than the gdb command windows, which is convenient for debugging.

A list of useful cgdb shortcuts:

`F5'
     Send a run command to GDB.

`F6'
     Send a continue command to GDB.

`F7'
     Send a finish command to GDB.

`F8'
     Send a next command to GDB.

`F10'
     Send a step command to GDB.

`spacebar'
     Sets a breakpoint at the current line number.

`t'
     Sets a temporary breakpoint at the current line number.

`i'
     Puts the user into "GDB mode".

`I'
     Puts the user into "TTY mode".

These short cuts is available in cgdb 0.6.5.

Updated on Apr. 2 2010. Short cuts are added.

Just add these gcc compile options:

-Wa,-adhln -g

-g: Produce debugging information
-Wa,option: Pass option as an option to the assembler
-adhln:
a: turn on listings
d: omit debugging directives; n: omit forms processing
h: include high-level source
l: include assembly

One example:
helloworld.c:

#include <stdio.h>
int main()
{
  printf("Helloworld!\n");
  return 0;
}

The command:

$ gcc -Wa,-adhln -g helloworld.c > helloworld.s

helloworld.s:

...

0:helloworld.c  **** #include <stdio.h>
1:helloworld.c  ****
2:helloworld.c  **** int main()
3:helloworld.c  **** {
19                            .loc 1 4 0

	// TODO: Add your control notification handler code here
	char name[4096];
	name[0] = '';
	OPENFILENAME ofn;
	memset( &ofn, 0, sizeof(ofn));
	ofn.lStructSize = sizeof(ofn);
	ofn.hwndOwner = m_hWnd;
	ofn.lpstrFilter = "文本文件(*.txt)*.txt";
	ofn.nFilterIndex = 1;
	ofn.lpstrFile = name;
	ofn.nMaxFile = 4096;
	ofn.lpstrTitle = "选择文件";
	ofn.Flags = OFN_CREATEPROMPT|OFN_ENABLESIZING|OFN_HIDEREADONLY;
	CString file_path;
	if( ::GetOpenFileName( &ofn ) )
	{
		file_path = ofn.lpstrFile; //打开的文件名
	}
	return file_path;
}

CFileDialog内部其实也是调用GetOpenFileName来打开文件对话框.OPENFILENAME的第一个字段指定该结构的大小.Windows的GetOpenFileName函数通过OPENFILENAME的大小来判断是使用新风格还是使用老风格.
在2000和XP中,OPENFILENAME结构新增加了数据成员.如果用的是老版本的windows头文件,编译的时候便是原来的结构大小,如果是win2000以后的头文件,使用的结构的大小就变大了.而MFC不知道新的结构成员的存在,所以MFC程序编译时,size还是老的大小,打开的还是老式的对话框.
