Question

我一直试图将Perl5模块Data::Printer加载到Perl6中，但遇到了困难。

我早些时候Cannot import Perl5 module using Inline::Perl5 into Perl6问过这个问题，确实从@raiph和伊丽莎白那里得到了有用的建议，但被建议再做一个问题

con@con-VirtualBox:~$ perldoc -lm Data::Printer
/usr/local/share/perl/5.26.0/Data/Printer.pm
con@con-VirtualBox:~$ perl6
To exit type 'exit' or '^D'
> use Inline::Perl5;
Nil
> use lib:from<Perl5> '/usr/local/share/perl/5.26.0/Data/';
Nil
> my @a = 1,2,3,4
[1 2 3 4]
> p @a
===SORRY!=== Error while compiling:
Undeclared routine:
    p used at line 1

应该加载p例程，但不是。

或者，我尝试加载，但这也会产生错误

我不知道如何将这个库有效地加载到Perl6脚本中。

p5_to_p6中不受支持的NativeCall :: Types :: Pointer <94859011731840>

这是Inline::Perl that was fixed 4 days ago中的错误。

仅执行zef install Inline::Perl5，就不会获得最新版本。这是我所做的：

# Install a position independent version of perl, 
#   see  https://github.com/niner/Inline-Perl5/
$ perlbrew install perl-5.29.7 --as perl-5.29.7-PIC -Duseshrplib -Dusemultiplicity
$ perlbrew install-cpanm
$ perlbrew use perl-5.29.7-PIC
$ cpanm Data::Printer
$ git clone https://github.com/niner/Inline-Perl5.git
$ cd Inline-Perl5/
# Run: 'zef uninstall Inline::Perl5' first if you already have it installed
$ perl6 configure.pl6
$ make
$ make install # this installs the latest version of Inline::Perl5
$ cd ..

然后我使用此脚本（ p.p6 ）对此进行了测试：

use Data::Printer:from<Perl5>;
my @a = 1,2,3,4;
p @a;

运行perl6 p.p6现在会给出：

[
    [0] 1,
    [1] 2,
    [2] 3,
    [3] 4
]

编辑：如果您已经安装了位置无关的perl二进制文件，则可以简化上述安装过程：

$ git clone https://github.com/niner/Inline-Perl5.git
$ cd Inline-Perl5/
$ zef uninstall Inline::Perl5
$ zef install . # or alternatively create the `Makefile` as above

如何在Perl6中加载Perl5的Data :: Printer？
