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

require "Text::CSV" is much different than require Text::CSV. For your code to work, you'd need to s-::-/-g on $module for the require (but not for the import).

You can also use a lexical. Note that my declarations happen when the statement is compiled but my initializations happen when the statement is run. So:

use strict; my $module; BEGIN { $module= ... ? 'Text::CSV' : 'Text::CSV_XS'; my $file= $module; $file =~ s-::-/-g; require "$file.pm"; $module->import(); } my $csv = $module->new();
Using eval "use $module" avoids this complication. Which to prefer is mostly a matter of taste (unless there is "risk" of $module ending up containing something strange).

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.
