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

It "works" fine for me:

use warnings; use strict; use Data::Dumper; my %d = map { $_, \&{'create_' . $_} } qw(first); print Dumper \%d; $d{first}->(); sub create_first { print "first!\n"; }

Output:

$VAR1 = { 'first' => sub { "DUMMY" } }; first!

...so you need to describe what's not working as expected.

Are you wanting to call the sub like this?:

$dispatch{_create_first}->();

If so, you need to map the '_create_' to both arguments to map. This example uses a second map() to modify the $_ variable on the way into the map that creates the actual dispatch table.

use warnings; use strict; use Data::Dumper; my %d = map { $_, \&{$_} } map {'create_' . $_} qw(first); print Dumper \%d; $d{create_first}->(); sub create_first { print "first!\n"; }

Output:

$VAR1 = { 'create_first' => sub { "DUMMY" } }; first!

  • 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).
