As a side effect of a7a5f14e, "123 x <product>" (with a space between the
number and the operator) is no longer supported. Breaking that was
unintentional, but since it was an undocumented feature and unintuitive
hack anyway, the feature won't come back.
When it still worked, it was implemented by *converting* a raw amount
(withdrawal or unlisted product, which you could still enter as just a
number -- since the aforementioned commit you need to be explicit and
use `withdraw` or `unlisted`) into a stub that would finally apply a
repetition when adding something else.
The signatures feature has been "experimental" since Perl 5.20 (May 2014), but
expected to stay. After 8 years I'm ready to take the risk :)
Have added Perl v5.28 (June 2018) as the minimum requirement, even though the
current revbank should work with 5.20, to see if this bothers any users. Perl
v5.28 is in Debian "buster", which is now oldstable.
The limit was mostly imposed because of the actually repeated
lines, which would scroll off the screen. Now that the quantity
is just displayed as a number, I don't really see any technical
reason for a low limit; maybe 200 is still too low.
There are some cases where repetition can be used with multi user transaction,
specifically if the repetition is done before any multi user stuff is added...
The 'stock' plugin uses the 'product_id' field in the cart item, but
this was not copied by the 'repeat' plugin. The confusion is caused by a
mismatch between the API for RevBank::Cart->add and the internal
representation.
