Public method to fix spaces problems in perl scalar

[bessarabov]

Here is the situation. In Perl script I create some text in scalar variable. Then I need to fix all that whitespaces problems in that scalar. Now i can save that variable to the tmp file, fix that file with the script whiter and then read that file. But it can't be called an elegant solution. I think that some public method should be added to the Test::Whitespaces to make it possible to simply fix scalar.

For now it is impossible to solve this issue without API change.

In the current version (1.0.0) you use Test::Whitespaces something like

use Test::Whitespaces {
    dirs => [ 'lib', 'bin', 't' ],
};

but this issue is about creating new sub, lets call it get_fixed_whitespaces() that will recieve $text and will return the fixed version of that text. To use that sub you need to use Test::Whitespaces, but use in the current version also starts testing.

I think that Test::Whitespaces interface should be changed to something like:

In xt/whitespaces.t:

use Test::Whitespaces;

Test::Whitespaces::test_whitespaces (
    {
        dirs => [ 'lib', 'bin', 't' ],
    };
);

In some Perl code:

use Test::Whitespaces;

my $fixed_text = get_fixed_whitespaces($text);
