我想为自己的“默认使用”创建一个模块,例如:
use My::perldefs;
以下内容是根据 (大多数基于tchrist的帖子。)
use 5.014;
use strict;
use features qw(switch say state);
no warnings;
use warnings qw(FATAL closed threads internal debugging pack substr malloc
unopened portable prototype inplace io pipe unpack regexp
deprecated exiting glob digit printf utf8 layer
reserved parenthesis taint closure semicolon);
no warnings qw(exec newline);
use utf8;
use open qw(:std :utf8);
use charnames qw(:full);
use feature qw(unicode_strings);
use Encode qw(encode decode);
use Unicode::Normalize qw(NFD NFC);
use Carp qw(carp croak confess cluck);
use autodie;
简单来说,想要通过use My::perldefs
实现以下目标:
- 完整且正确的UTF8支持,以及
- 启用所有现代Perl特性。
根据最近的问题,一个好的起点是uni::perl。它几乎可以满足我所有的需求,只需要添加:
use feature qw(unicode_strings);
use charnames qw(:full);
use Encode qw(encode decode);
use Unicode::Normalize qw(NFD NFC);
use autodie;
我将授予赏金给能够使用有效且正确的方式扩展下面的uni::perl(插入如下)的人。
请帮忙创建一个适用于utf8和现代perl的好的样板。谢谢。
以下是uni::perl的副本。
package My::perldefs;
use 5.014;
BEGIN {
${^WARNING_BITS} ^= ${^WARNING_BITS} ^ "\xfc\x3f\xf3\x00\x0f\xf3\xcf\xc0\xf3\xfc\x33\x03";
$^H |= 0x00000602;
}
m{
use strict;
use warnings;
}x;
use mro ();
BEGIN {
for my $sub (qw(carp croak confess)) {
no strict 'refs';
*$sub = sub {
my $caller = caller;
local *__ANON__ = $caller .'::'. $sub;
require Carp;
*{ $caller.'::'.$sub } = \&{ 'Carp::'.$sub };
goto &{ 'Carp::'.$sub };
};
}
}
sub import {
my $me = shift;
my $caller = caller;
${^WARNING_BITS} ^= ${^WARNING_BITS} ^ "\xfc\x3f\xf3\x00\x0f\xf3\xcf\xc0\xf3\xfc\x33\x03";

# use feature

# use mro 'c3';
mro::set_mro($caller, 'c3');
#use open (:utf8 :std);
${^OPEN} = ":utf8\0:utf8";
binmode(STDIN, ":utf8");
binmode(STDOUT, ":utf8");
binmode(STDERR, ":utf8");
for my $sub (qw(carp croak confess)) {
no strict 'refs';
*{ $caller .'::'. $sub } = \&$sub;
}
while (@_) {
my $feature = shift;
if ($feature =~ s/^://) {
my $package = $me. '::'. $feature;
eval "require $package; 1" or croak( "$@" );
$package->load( $caller );
}
}
}
1;
