我正在尝试将嵌入式Pod作为ANSI文本输出到终端。在Perl 5中,我可以使用Pod::Text::Termcap
:
use strict;
use warnings;
use Pod::Text::Termcap;
my $str = do {local $/; <DATA>};
my $parser = Pod::Text::Termcap->new();
$parser->parse_string_document( $str, \*STDERR );
__DATA__
=head1 SYNOPSIS
my_test_command I<filename> [OPTIONS]
=head1 ARGUMENTS
=over 4
=item I<filename>
File name to test
=back
=head1 OPTIONS
=over 4
=item B<--help>
Prints help
=back
=head1 DESCRIPTION
A sample test command with embedded Pod
输出:
我试图在Perl 6中实现相同的目标:
use v6;
%*ENV<POD_TO_TEXT_ANSI> = 1;
my @lines;
for $=pod -> $pod-block {
for $pod-block.contents -> $pod-item {
use Pod::To::Text;
push @lines, pod2text($pod-item);
}
}
say @lines.join("\n\n");
=begin pod
=head1 SYNOPSIS
my_test_command I<filename> [OPTIONS]
=head1 ARGUMENTS
=item I<filename>
File name to test
=head1 OPTIONS
=item B<--help>
Prints help
=head1 DESCRIPTION
A sample test command with embedded Pod
=end pod
输出:
如所见,Perl 6输出中缺少ANSI termcap转义。如何在Perl 6中获得ANSI功能,例如粗体字和带下划线的文本?
答案 0 :(得分:4)
Pod :: To :: Text接受启用它的环境变量POD_TO_TEXT_ANSI
。但是,如果在解析perl 6代码之前加载了所选的DOC
模块,则在Pod::To
相位器中设置env var可能为时已晚。

关于您的问题:
如何在Perl 6中获得ANSI功能,例如粗体字和带下划线的文本?
您可能想给Terminal::ANSIColor
a try,但是您需要自己添加ANSI转义码;在POD上不会自动工作
