NegativeK writes "I work at a local comic and games shop, and I've been kicking around what it would take to implement a barcode scanner and more detailed inventory control. Currently, the setup is a low-tech register that tracks general areas of sales: new comics, ccgs, Games Workshop, rpgs, etc. Requirements include FOSS on Linux, the ability to use a cheap scanner, datamining, and output in a useful format (perhaps OpenOffice spreadsheet). The idea hasn't been pitched to the shop owner yet, so ease of use is probably more important than anything — but breaking out the programming books to work on parts isn't out of the question for me. Assuming the actual register stays, what resources are out there for a barcode/inventory implementation?"
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
