Parse :: CPAN ::作者的目的是什么？

Question

Parse :: CPAN :: Authors模块的目的是什么？

  use Parse::CPAN::Authors;

  # must have downloaded
  my $p = Parse::CPAN::Authors->new("01mailrc.txt.gz");
  # either a filename as above or pass in the contents of the file
  my $p = Parse::CPAN::Authors->new($mailrc_contents);

  my $author = $p->author('LBROCARD');
  # $a is a Parse::CPAN::Authors::Author object
  # ... objects are returned by Parse::CPAN::Authors
  print $author->email, "\n";   # leon@astray.com
  print $author->name, "\n";    # Leon Brocard
  print $author->pauseid, "\n"; # LBROCARD

  # all the author objects
  my @authors = $p->authors;

描述

Comprehensive Perl Archive Network(CPAN)是一个非常有用的Perl代码集合.它有几个托管文件的索引,包括"authors"目录中名为"01mailrc.txt.gz"的文件.该文件包含许多有关CPAN作者的有用信息,该模块提供了一个简单的接口,用于包含在其中的数据.

请注意,此模块不关心下载此文件.你应该自己做.

这是做什么的？到底有什么好处呢？

它返回以下数据

my $author = $p->author('LBROCARD');
 $a is a Parse::CPAN::Authors::Author object
 ... objects are returned by Parse::CPAN::Authors
print $author->email, "\n";  leon@astray.com
print $author->name, "\n";  Leon Brocard
print $author->pauseid, "\n";  LBROCARD...

...所有CPAN作者及其在模块,名称,邮件地址等方面的工作.

您在描述部分的哪个部分遇到了麻烦？

CPAN有一些描述其内容的元数据文件.此模块允许您解析其中一个并以简单的方式提取其数据.

除非您正在编写与CPAN以编程方式交互的软件,否则此模块对您来说不太可能有用.如果我没记错的话,Leon写的是因为他需要它来编写CPAN :: Mini :: Webserver.
