    好久好久没来blog上写文章了,公司最近真很忙。
    稍微安顿下来了,客户的一些通讯资料和我的破手机成了矛盾,只能存储200个号码,而且在SIM卡中,慢死不说,装不下呀,无奈,花了个下午,弄个能支持任意字段的通讯录出来玩玩,其实这种款式的通讯录,命令行下的,以前也设想过了呢:)

    程序叫做 dcontacts,是 Perl写的,使用 MySQL数据库,要调用 Perl的 DBI连接数据库,如果要使用,需要自己准备安装好这些。

    看下程序的使用帮助

dorainm@thinkpad/~ $ dcontacts --help
dcontacts 0.2
Copyright (C) 2008 dorainm <dorainm@gmail.com>
Usage :
Help Info. : dcontacts --help
Re/Install : dcontacts INSTALL
Backup Data : dcontacts BACKUP
Create Name : dcontacts newname
Update Name : dcontacts oldname newname
Remove Name : dcontacts oldname NULL
Create Item : dcontacts name kind newitem
Update Item : dcontacts name kind olditem newitem
Remove Item : dcontacts name kind olditem NULL
AND Search : dcontacts AND keyword,...
OR Search : dcontacts OR keyword,...
dorainm@thinkpad/~ $


    嗯,这个是 --help的屏幕,打开程序源码,修改%conf里面,数据库配置,dbhost表示数据库服务器、dbbase数据库名、dbuser用户名、dbpswd连接密码,现在让程序安装数据库表吧。

dorainm@thinkpad/~ $ dcontacts INSTALL
INSTALL operation will CLEAR all the DATA if it is
Are you SURE (yes/NO) ? yes
Done
dorainm@thinkpad/~ $


    有行提醒,安装数据库表,会导致以前存在的表的数据丢失,因为程序是 DROP旧表后,CREATE新的表结构的。
    现在来添加资料,看示范和命令吧

//新建一个姓名
dorainm@thinkpad/~ $ dcontacts dorainm

//添加一个email,用户可以自定义类型
dorainm@thinkpad/~ $ dcontacts dorainm email dorainm@gmail.com

//当然,相同类型可以存多个项
//比如再存一个email,要dorainm@funtin.com
dorainm@thinkpad/~ $ dcontacts dorainm email dorainm@funtin.com

//添加一个相同的电子邮箱为dorainm,会被提示错误
dorainm@thinkpad/~ $ dcontacts dorainm email dorainm@gmail.com
it already has the item as 'dorainm@gmail.com'

//添加一个blog地址
dorainm@thinkpad/~ $ dcontacts dorainm blog dorainm.cublog.cn

//直接添加项,如果发现没有这个名字,程序会自动添加
dorainm@thinkpad/~ $ dcontacts edison email edison@funtin.com

//直接添加项,如果发现没有这个类型,程序也会自动添加
dorainm@thinkpad/~ $ dcontacts david mobilephone 12345678901


dorainm@thinkpad/~ $ dcontacts edison mobilephone 98765432109

//添加姓名
dorainm@thinkpad/~ $ dcontacts fentin

//不小心写错名字了,直接修改
dorainm@thinkpad/~ $ dcontacts fentin funtin

//删除名字的话,就把名字重命名为NULL
dorainm@thinkpad/~ $ dcontacts funtin NULL

//添加一个已经存在的名字,就会显示改名字的详细资料
dorainm@thinkpad/~ $ dcontacts dorainm

    呃,就这么用,AND 和 OR还是好用的,而且在姓名、类型、项值里面,全部LIKE '%$keyword%'来搜索,比较有感觉,嘻~
    只是条件搜索目前还不能组合使用,不太会用参数表达复式的组合,用波兰表达式读取类似四则混合运算的参数?!

    程序还有一个备份功能,备份数据库,程序会调用mysqldump命令,在 ~/.dcontact/backup目录下,以当前的日期、时间为文件名,备份一个 .sql的数据库文件,供用户恢复时候使用。

dorainm@thinkpad/~ $ dcontacts BACKUP
dorainm@thinkpad/~ $ ls -l ~/.dcontacts/backup
