( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Quick and dirty (Windows 7, Perl 5.8.9):
Module check_module.pm:

package check_module; use Exporter; our @ISA = qw(Exporter); our @EXPORT = qw(@checks); our @checks = ( { name => 'Anybody home?', script => 'qq/echo $home_dir/', }, ); 1;
Note esp. that  'qq/echo $home_dir/' is single-quoted in the .pm file.

Script:

c:\@Work\Perl\monks\ExReg>perl -wMstrict -le "use strict; use warnings; use check_module; my $home_dir = '/home/mine/'; for my $check ( @checks ) { print qq{Checking $check->{name}}; my $evaled_script = eval qq{$check->{script}}; print `$evaled_script`; } " Checking Anybody home? /home/mine/
(Update: The trick here is to eval the  $check->{script} string from the module in the scope of the script in which  $home_dir is declared and initialized.)

Update 1: If you had included the  use warnings; use strict; statements in the .pm module (after the package statement), you would have had a slightly earlier and possibly slightly more informative notification that something was going sideways.

Update 2:

... [a] system that cannot use CPAN ...
See Yes, even you can use CPAN.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
