给你的Linux或Unix控制台创造一棵圣诞树玩玩吧。在此之前,需要先安装一个Perl模块,命名为Acme::POE::Tree。这是一棵很喜庆的圣诞树,我已经在Linux、OSX和类Unix系统上验证过了。
安装 Acme::POE::Tree
安装perl模块最简单的办法就是使用CPAN(Perl综合典藏网(Comprehensive Perl Archive Network))。打开终端,把下面的指令敲进去便可安装Acme::POE::Tree。
## 以root身份运行 ## perl -MCPAN -e 'install Acme::POE::Tree'
示例输出:
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 Installing /home/vivek/perl5/man/man3/POE::Loop::IO_Poll.3pm Installing /home/vivek/perl5/man/man3/POE::Pipe::TwoWay.3pm Appending installation info to /home/vivek/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/perllocal.pod RCAPUTO/POE-1.367.tar.gz /usr/bin/make install -- OK RCAPUTO/Acme-POE-Tree-1.022.tar.gz Has already been unwrapped into directory /home/vivek/.cpan/build/Acme-POE-Tree-1.022-uhlZUz RCAPUTO/Acme-POE-Tree-1.022.tar.gz Has already been prepared Running make for R/RC/RCAPUTO/Acme-POE-Tree-1.022.tar.gz cp lib/Acme/POE/Tree.pm blib/lib/Acme/POE/Tree.pm Manifying 1 pod document RCAPUTO/Acme-POE-Tree-1.022.tar.gz /usr/bin/make -- OK Running make test PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/01_basic.t .. ok All tests successful.

在Shell中显示圣诞树
只需要在终端上运行以下命令:
perl -MAcme::POE::Tree -e 'Acme::POE::Tree->new()->run()'
示例输出
Gif 01: 一棵用Perl写的喜庆圣诞树
树的定制
以下是我的脚本文件tree.pl的内容:
#!/usr/bin/perluse 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();
这样就可以通过修改star_delay、run_for和light_delay参数的值来自定义你的树了。一棵好玩的终端圣诞树就此诞生。
