Object database

by Boris SpasojeviÄ

Hi all, I have a need to persist a really large and funny object structure in Pharo (a huge Dictionary of Dictionaries) and I would like to be able to query this data from a remote image. Basically what I am looking for is some form of database that would allow me to input elements in to this structure from one image, and read them out in another image with queries like i.e. dictionaryOfDictionaries select: [ :each | (each keys includes: key1) and: [ each keys includes: key2 ] ] It does not have to be strictly an OO database, anything that could enable me to do this fast and easy would be nice. Any suggestions/ideas/comments?

I am using a 3 letter prefix for my own projects. It works well too. Lack of imports is not that bad. Cleaner code most of time.

Re: [Pharo-users] PettitParser approach help

by Juan Ignacio Vaccarezza

Doru, thanks for the answer. I'm doing it in the way you suggest. What I ment by know how to add to the result is the following: (Modifing a bit the example you gave me) a := 'AAA' asParser flatten ==> [:token | ResultSelfAdder new objectToAdd: token; selector:#addA ]. b := 'BBB' asParser flatten ==> [:token | ResultSelfAdder new objectToAdd: token; selector:#addB ]. c := 'CCC' asParser flatten ==> [:token | ResultSelfAdder new objectToAdd: token; selector:#addC ]. meaningful := a / b / c. other := (meaningful / #newline asParser) negate star flatten. log := (meaningful / other) delimitedBy: #newline asParser. result := log end parse: 'AAA AAA BBB CCC AAA other text CCC BBB other text'. niceObject := ParseResult new. result do: [:eachResult | eachResult addYourselfTo: niceObject] ResutlSelfAdder>>addYourselfTo: aParseResult aParseResult perform: self selector with: self objectToAdd. I hope is clear now, Im pretty new at asking on mailists, and sometimes I forget to add crucial information Thanks again for your time!
