An ubuntu package for 0.9.3 Release Candidate.

May 23, 2010 3 comments

Hello world!

As a result of my bad luck, my development machines died in this year (and the end of the 2009). That is the reason for the 0.9.3 release delay.

I have managed to make an ubuntu package (.deb) for ubuntu 10.04 amd64.  This package is not perfect, and maybe it misses some dependencies. I want to note that i have no experience in making .deb packages, it is made using an automatic builder.

Said that, i can release the package to the wild.

You can read the changelog to see what’s new.

Download here.


After installing the .deb, install the mysql server/client as needed ( if multiple POS terminals are going to use a single database, only install mysql server on one computer, and mysql client on all).  And then you can create the database using the file included in the package, installed at /usr/share/kde4/apps/lemon/lemon_mysql.sql . Run the script as described in the wiki. If you updated lemonpos, then you may want to update your database, instead of running lemnon_mysq.sql, run the fix script if you update from version 0.9.2 or 0.9.1.

There are two PDF documents installed at /usr/share/doc/lemonpos/ on two folders, one for english and other for spanish.

If you got an error when installing the package, see the error detail, maybe some dependencies are not satisfied.

The dependencies for the package are:

There is a Release Candidate for the persa branch in the git repository, also there is a string freeze for translators. In the next week, the new version (0.9.3) will be released, with bug fixes and improvements.
The directions to get it are on the wiki

The new git repository is now containing the updated code. It is mirrored in sourceforge and github, being the main one on gitorious.

As the ongoing work on the merge, now the product editor is working fine with the new features.  You can see a screenshot:

Release 0.7.3 and starting new features

April 5, 2009 7 comments

Yesterday was released the 0.7.3 version with some fixes.

From now, Im starting to incorporate new features that users requested. This requieres some big changes to the database structure, and starting at SVN revision 285 I have introduced new tables that will replace some fields from the products table. So I advice you to use SVN revision 284 or the 0.7.3 release. The SVN always has new code that im testing and may not always work as it should -now it has a floating toolbar for product filters that does not work-.

The big change Im working is to support different stores with a single stock managment from which a product could be sold from a different location -store,warehouse-. Also, a product could have peculiarities that differentiate from the same product, such as color and sizes, having the same code -and price,cost,etc-.

So, there are good things to come, stay tunned.

Work in progress

Hello people.

I have been working to rewrite some code in lemonpos to separate a little more the logic and presentation from the data access. It’s a hard work to complete this task, but the result will help to have a more readable and maintainable code. Aside this work, I have been adding things and correcting the database structure.

The new things include a new dialog to check prices without entering items into the “basket”, accessible with a simple key stroke. A new field in the offers-table of the database to store begining of offers. Code to delete offers when deleting products. Filter for the offers now works, and you can filter offers by dates (month offers, finished offers) in the administration tool.

Here some screenshots:

Offer Editor

I hope, in a couple of weeks, to make a new release.
Stay tuned.

An improvement to squeeze

February 28, 2008 Comments off

Now, editing an item offer, the appropiate editor is created when double click on each field at the tableview. It sets minimum and maximum values for each data field, so you cannot accidentally set a month=30 or a day=90.

After some weeks of inactivity, i have to make little improvements each week.
