On of the awesome things we will be able to do with the TT syntax is the support of plurals.
For instance we will be able to send a list of items, checkouts, etc. to the notice template.
That way we will get rid of our custom syntax like <<items.content>> or <item></item> for instance.
The existing code already has the playground for that but it is not used.
Basically the idea is to add a "loops" key which can contain a list of
object to retrieve from the DB and send to the template.
For instance:
loops => { overdues => [ $itemnumber_1, .., $itemnumber_N ] }
will send a variable "overdues" to the template. It will contain the
Koha::Checkout objects relative to the id passed.
There is one quite big inconvenient to this approach so far: since we
are still supporting the historical syntax, the objects can be fetch by
a script, then the script will send the id to GetPreparedLetter which
will refetch them.
This must be improved, but I suggest to do that later.
Test plan:
prove t/db_dependent/Letters/TemplateToolkit.t
should return green
