2.项目知识点

代码风格 (注释，命名...)

复用开源代码

设计模式 (Singleton,Factory,Bridge,Observer,Strategy,Template...)的使用

项目平台移植

多继承，虚继承

抽象基类虚析构

有const对象，2个版本的函数实现

智能指针的实现

虚函数对于子类覆盖，本类间也可以重载

面向对象思想

Vector模板的实现

'=' 重载实现 return *this

static 成员，类外初始化

STL模板使用

一些关键词的使用 explicit, inline,namespace,friend

try/catch 异常处理

sort 调度器的实现

实现静态链接库 (libATM.a)

模拟文件系统 (AlexFs)

代码构建工具 scons

文档生成工具 Doxygen

4.about bin/ directory

Just use the GnuWIn32 project.

The GnuWin32 project provides native ports in the form of runnable computer programs, patches, and source code for various GNU and open source tools and software, much of it modified to run on the 32-bit Windows platform. The ports included in the GnuWin32 packages are:

GNU utilities such as bc, bison, chess, Coreutils, diffutils, ed, Flex, gawk, gettext, grep, Groff, gzip, iconv, less, m4, patch, readline, rx, sharutils, sed, tar, texinfo, units, wget, which

Archive management and compression tools, such as: arc, arj, bzip2, gzip, lha, zip, zlib.

Non-GNU utilities such as: cygutils, file, ntfsprogs, openssl, pcre.

Graphics tools.

PDCurses

Tools for processing text.

Mathematical Software and Statistics Software.

To use these commands ,just run windows.bat!

In this way , to realize external command support ,then we can not only design command embedded in shell,

we can design some commands projects independent from shell project.

5.Addition

atm command's user information

user-name password

000001 123456

000002 111111

000003 234567

000004 345678

000005 456789

000006 567891

6.Tab Completion

Linux version ,support tab completion.

Use the GNU readline library.

sudo apt-get install libreadline6-dev

or

Use the readline6.1 source code

./configure

make

make install

In Windows ,just use cygwin

./configure

make

get the libhistory.a , libreadline.a

also can realize tab completion .
