Shopping List
Details
Shopping List is under GNU GENERAL
PUBLIC LICENSE. It is written by Simone Pernice from
scratch.
Version 1.7.1, build 90, created on 28th October 2007 in Turin,
Italy.
Shopping List needs a MIDP 2.0 phone. The synchronize function was
tested on Motorola phones.
So if you want to ask questions, suggest improvements or changes,
fix bugs, send a donation or postcard contact Simone.
Help
This program is given as it is, WITHOUT any warranty. Supermarket
stores a list of shops, each one is divided in a set of sections
ordered like the shop arrangement. For every section there are the
available elements. Select what to buy the next time in the shop to
show them in the basket list. Once in the shop, just select the
elements in the basket list while put them in the actual basket.
Supermarket computes the amount considering discount tickets, warn
you if something is missing and update statistics on element
consumption for future suggestions.\nTo use Supermarket, define the
name of your shops in SHOPS LIST, in order to change the current
shop push 'USE NOW' button. Set your current shop sections in
SECTION LIST in the order you usually go through them while buying
in the shop. If the section contains some element, three radio
buttons appear showing statistic computation status for the
elements (none, all, some) and it is possible to change it to none
and all to update all the elements in the section. Put in TICKET
LIST your discounts/banknotes in the priority order and quantity (0
means no limit), eventually select the ones you will use the next
time. For every section add in the SHOPPING LIST the items you
usually buy, you can enter the same item several times. Every
element has an unitary price, number of units to buy (it can be
decimal if you use price at kilo), the discount percentage (0 for
no discount), the number of times after the product should be
bought (0 to avoid to keep statistics for that product, it is
automatically updated after every shop session), the number of
times the product was not bought (read only and kept update only if
times to buy > 0), and its category. In shopping list select the
ones you'll buy next time: they will appear on basket list. In the
BASKET LIST select them again while you're putting them in the
shopping basket. Use EVAL to calculate the required cash and the
number of discount tickets, it will also suggest the most likely
element to buy to fully use the final ticket. If the basket is full
and ShppingList is closed, times not bought and times to buy are
automatically updated and the elements in the basket are
unselected. Use GUESS to fill automatically the most likely items
to buy. The first time ShoppingList is started default elements,
categories and tickets are loaded.
Synchronization Procedure
I usually receive a lot of questions about the synchronization. It
is based upon J2ME Serial Connection interface, which let the phone
links to the PC through USB/Serial/IrDA protocol. On the PC a
simple terminal emulator will receive the data in text format and
save it. Unfortunately the link procedure is not standardized by
J2ME, therefore every manufacturer needs its own steps and phone
settings. Here I will describe the procedure for Motorola
phones.
In order to save ShoppingList databases on your PC select
synchronize option and then choose the first serial port of the
list (I see COM0 on Motorola). Select backup function. The phone
will ask you if ShoppingList is allowed to use your phone com port.
Answer yes and (only then) plug an USB cable from your PC to your
phone. Then start HyperTerminal (you can find it in start ->
programs -> accessories -> communication). It will ask for a
connection name (write whatever you want) and then a port: select
the same com port of the phone (which you can find in device
manager after your phone is linked to the pc). At this point in
Hyper Terminal select transfer -> capture text and chose a file
name. When ready push a key in Hyper Terminal to get all your
database in text format. Eventually in HyperTerminal push transfer
-> capture text -> stop. In your text file will be stored all
your databases. The backup files are simple text which you can
easily manipulate in order to add, delete or modify records.
The restore procedure is exactly the opposite of backup: in
ShoppingList select synchronize option and then choose the first
serial port of the list (I see COM0 on Motorola). Select RESTORE
option. The phone will ask you if ShoppingList is allowed to use
your phone com port. Answer yes and (only then) plug an USB cable
from your PC to your phone. Then start HyperTerminal (you can find
it in start -> programs -> accessories -> communication).
It will ask for a connection name (write whatever you want) and
then a port: select the same com port of the phone (which you can
find in device manager after your phone is linked to the pc) and
set the lowest baud rate available. Eventually in Hyper Terminal
select transfer -> send text and choose an old backup file that
you want to restore on your phone.
