All the applications I know are using SqueakDBX but trought GlorpDBX (an ORM). But anyway, I am not sure I undertand your problem. I recommend you to take a look to all the tests in the class DBXQueryTest. For example, you can do this: testIterateResultSet | conn result select aRow | conn := self doConnectAndOpen. select := 'SELECT * FROM student'. result := conn execute: select. [ aRow := result nextRow. "Do something with aRow" ] doWhileTrue: [ aRow notNil ]. self assert: aRow isNil. result releaseResult. conn disconnect And to DBXRow, you can ask values (accessing by index or by name), descriptions, converting or not so String, etc... For example, check the class DBXTranscript >> showResultSet: resultSet showResultSet: resultSet | stream | stream := String new writeStream. resultSet columnDescriptions do: [:each | stream nextPutAll: each name] separatedBy: [stream nextPutAll: ' | ']. Transcript show: stream contents; cr. resultSet rowsDo: [:row | stream := String new writeStream. row values do: [:each | stream nextPutAll: each asDbxString] separatedBy: [stream nextPutAll: ' | ']. Transcript show: stream contents; cr] What I mean is that since you have reified DBXRow, DBXResultSet, etc...then you can do whatever you want with that.

[Pharo-project] Issue 3383 in pharo: [FIX] make String >> #subStrings: do less allocation

by pharo＠googlecode.com

Status: Accepted Owner: philippe.marschall Labels: Type-Patch Difficulty-Easy Importance-Low New issue 3383 by philippe.marschall: [FIX] make String >> #subStrings: do less allocation http://code.google.com/p/pharo/issues/detail?id=3383 String >> #subStrings: does a lot of allocation. It allocates a new string for almost every character. So if you do something like '/alongUrl/withaPathElement/andSomethingMore' subStrings: '/' about forty strings are allocated. This can easily be avoided using write streams. The method could probably be made even faster by using #indexOfSubCollection:startingAt: and just copying with the correct size. I will post a patch but I first need an issue number that I can reference.

Re: [Pharo-project] Parsing and navigating Html

by Johan Brichau

SeasideTesting uses the XMLParser for parsing html files and has support for querying them. It's not complete but, for example, covers quite a lot of cases needed in testing, obviously On 04 Dec 2010, at 22:15, Sean P.

Indeed Flattr is an easy way to donate. I've seen http://pharobyexample.org/ has a Flattr button. Can you tell how much it generates per month ?
