Linux/Unix的桌面乐趣:在你的终端显示圣诞树

Posted by 撒得一地 on 2015年12月23日 in Linux笔记

让我们在Linux或Unix控制台上显示圣诞树,不要太惊讶,这是纯娱乐。首先,你需要安装一个Perl模块,该模块名为Acme::POE::Tree。
这是一个显示动画圣诞树模块。我已经在Linux上,OS X和类unix系统上测试成功了。

安装Acme::POE::Tree

安装任何perl模块的最简单方法是使用cpan(Comprehensive Perl Archive Network)。打开终端应用程序并输入以下命令安装

Acme::POE::Tree:

## run as root ##

perl -MCPAN -e 'install Acme::POE::Tree'

安装过程输出:

Installing /home/vivek/perl5/man/man3/POE::NFA.3pm
Installing /home/vivek/perl5/man/man3/POE::Kernel.3pm
Installing /home/vivek/perl5/man/man3/POE::Loop.3pm
Installing /home/vivek/perl5/man/man3/POE::Resource.3pm
Installing /home/vivek/perl5/man/man3/POE::Filter::Map.3pm
Installing /home/vivek/perl5/man/man3/POE::Resource::SIDs.3pm

  RCAPUTO/Acme-POE-Tree-1.022.tar.gz
Tests succeeded but one dependency not OK (Curses)
  RCAPUTO/Acme-POE-Tree-1.022.tar.gz

在shell显示圣诞树

简单地键入以下命令:

perl -MAcme::POE::Tree -e 'Acme::POE::Tree->new()->run()'

此时屏幕输出:
在Perl中的动画圣诞树

这里是my tree.pl脚本:

#!/usr/bin/perl
use Acme::POE::Tree;
my $tree = Acme::POE::Tree->new(
{
  star_delay => 1.5,  # shimmer star every 1.5 sec
  light_delay => 2,   # twinkle lights every 2 sec
  run_for => 10,  # automatically exit after 10 sec
}
);
$tree->run();

现在你可以通过修改star_delay(闪烁延迟时间),run_for(运行时长),和light_delay(闪烁持续时间)参数来设置你的圣诞树。还有,在你的shell里面出现了一棵圣诞树,是不是非常有趣?
