INTRO
MoneyBook is a simple ruby command line application to track group expenses and know exactly how much each one of your friends owes you from your last trip!
It's not super easy to use, nor is it meant to be (since I wrote it for myself), but it's meant to be powerful and useful.
QUICK START
to install simply do: gem install moneybook
now to create your first moneybook file do: moneybook new TITLE
and follow the onscreen instructions (give title, list of people in the group and optionally a currency exchange) next edit the file as you wish and, when you want to know how things stand (how much each one has to give/receive) simply do this: moneybook parse moneybook_file.txt
If you want to see intermediate results (they will give you a better understanding of the whys..) simply add a -i option, like this: moneybook parse -i moneybook_file.txt
To see other available options do this: moneybook parse --help

each table is the result of each line in the source file, in each table there are 4 lines: the first line is what's been payed [given], the second line is who should have payed it [spent], then third line is the difference (so if the number is negative, the person owes money to those whose number is positive), and the fourth line is the total balance that far.
At the end the total balance is also printed in words, kevin and mary both give something to jack! And for each one is said how much he spent and how much he actually gave. The balance is the difference: given - (spent + paybacks). Paybacks are not considered in the spent field.
