>Subject: [PATCH] [SIGNED-OFF] Bug 12409: Fix fields order on exporting to
> bibtex
>
>The C4::Record::marc2bibtex subroutine supposes hashref keys are sorted
>which is wrong with perl 5.18
>
>Note that the t/db_dependent/Record.t fails without this patch.
>
>Test plan (for perl >= 5.18 only):
>1/ prove t/db_dependent/Record.t should return green
>2/ Try to export a record to bibtex and verify the order is correct
>(should be author, title, year, published, etc.).

>Wrong Bug number on heading.
>Work as described, test pass, no koha-qa errors.

>The problem is to think that a hash returns
>keys in a particular order, that's not true
>and no matter which perl version.
>
>Code as was left is... misleading.
>Comments talks about a hash, which is no more.
>On array asignment "a => b" is equivalent to "a, b",
>but the former is usually used on hashes, so a
>replacement of '=>' by ',' could clarify what are we storing.
