I am trying to match either of the string in the Perl Template::Toolkit
module.
url
is getting its value from the script.
[% IF url == ("a/b/c" | "d/e/f") %]
Is this the right way of doing it? I looked at the documents. It mentioned the 'matches' method, but I am looking for a simpler way of doing it.
I think it's a little awkward to use regular expressions in Template::Toolkit
, but in this case you can just write
[% IF url == 'a/b/c' or url == 'd/e/f' %]
If you need anything more complex then you're probably misunderstanding the rôle of templates, but you can always evaluate a Boolean condition within Perl and pass that value into the template
Update
Or you could use SWITCH
, like this
[% SWITCH url %]
[% CASE [ 'a/b/c', 'd/e/f' ] %]
...
[% END %]
You can use the match virtual method to test a regexp. This is as simple as it gets.
use strict;
use warnings;
use Template;
my $t = Template->new;
$t->process( \*DATA, { urls => [qw(
http://example.com/a/b/c
http://example.com/xyz
http://example.com/x/d/e/f
)] } );
__DATA__
[% FOREACH url IN urls %]
[%- IF url.match('a/b/c|d/e/f') %]
[%- url %] - match
[%- ELSE %]
[%- url %] - NO match
[%- END %]
[% END %]
Outputs:
http://example.com/a/b/c - match
http://example.com/xyz - NO match
http://example.com/x/d/e/f - match
Alternatively, perform the match on the URL in your script then pass the boolean outcome to the template.
