Celina is a cell phone invoice analyser I wrote some years ago. It parses PDF files of a defined format (the format my former provider used) and stores the extracted data in an sqlite database. This then allows for calculation of statistics on the gathered data.

My intention was to get a grip on what my usual cell phone data actually looks like to be able to make a more informed, rational decision on what I would want from my next contract.

• So far celina is neither configurable through a file, nor does it sport a plugin architecture for parser modules. So enabling it to parse a different invoice format will essentially mean adjusting regexs in the code. But while we are at it, we might as well make the whole mechanism more generic.
• Celina uses elixir as an ORM, so it should be easy to swap sqlite for another DBMS (yes, we would want that to be configurable as well), but so far there is no way to remove data from the data base (not even to overwrite it).
