Oberon Database
by Dan Parnete 19 Sep '05

19 Sep '05

Hello, I have read this list archives, the documentation inside the distributions, some extra found on the web and I understood. Database is a Tabu word in this community, and is better to not talk about. There is no trace in any distribution (excluding the commercial BlackBox) and the new Bluebottle project doesn't intend to implement one. Ok. It's a choice of live. But don't tell me none of you never needed to put some data altogether. I can't believe nobody extended at list the Library code to more flexible collections management. I saw some database projects started long time ago. Where are this implementations? In other words: if I need a database, have I write it myself? Dan

The driver is currently only available for the new Bluebottle OS. http://bluebottle.ethz.ch It should not be too difficult to make a Native Oberon driver out of the Bluebottle OS driver. But... I have no time to do this myself. --Thomas Frey

Hello I want to emulate the mouse-movements an the keyboard-entries with USB with the bluebottle (acutally with Windows, in future with native version) on another computer, linked to this USB-interface. Is this possible perhaps with V24 or another tool? Bruno Hürlimann

I thought someone wrote about: 'traversing the viewer heirarchy upwards [towards the root] to find a specific viewer, and that crossing over to the other branch of the tree was not possible' ?? Felix Friedrich wrote: > There is no way to access all viewers without modifying Viewers.Mod That confuses me since [although I've never investigated deeply] Chapter5.Text shows :- ... Display Root Figure 5.4 Example structure of the display space And simplistically, <F9> clearly 'talks' to all viewers. Aren't all viewers accessible from "Display Root" ? Are the viewers also linked in the reverse direction - I guess not ? Where am I misunderstanding this thread ? == Chris Glur.

Hi Felix, thanks for your code. I will give it a try. Felix Friedrich <friedrich(a)gsf.de> wrote: > As far as I remember, there is no way to > (portably) traverse all viewers/frames in the display space (without > using Display.Broadcast which in your case does not make sense). But this gives me another idea. Perhaps Display.Broadcast MAKES sense in my case. Because I know the name of the document I expect my object to be contained ! So perhaps taking the document (or the panel it contains) as context for FindObj() could save my day. So I have another question: Can I find a document with a given name if it's opened ?

Even if you forget to FTP.Close you can't FTP.Open again without re-booting. Needs refining. John M. Drake wrote:- > I've uploaded it to the WebDav.

Looking at the dir of contents: UserGuide.Text 19.08.2004 22:20:14 13132 59% But Id UserGuide.Text is already used, so temporarily do: System.RenameFiles SYS:UserGuide.Text => SYS:ObnUserGuide.Text ~ and extract and examine the 'new' UserGuide.Text == (** Dps Application Framework, Copyright 2004 DP Sisteme 2000 srl *) ...Everything is written in Oberon, except DpsServer module witch is in Active Oberon. .... Well since I don't [yet] use Active Oberon , that's the end for me ? Packages should introduce their requirements in a heirarchy to enable the 'investigator' to abort as soon as possible, i.e. with minimum cost. I.e. one should be able to fetch the requirements and minimal description without 'buying' the whole package. This common sense principle eg. that each contributor's directory should have a standard ReadMe&Contents ..... These rules need to be WRITTEN DOWN. The developer becomes so engrossed in his 'technicalities' that he can't be bothered with these apparent trivialities. The same way as societies use methods formulated thousands of years ago [Greek, Roman civilisations] , software development is a human 'emergent' activity where proven good methodology should be copied from the past and not reinvented, painfully every time. I.e. written rules/guidelines. Why is TextGadgets.Mod included in the zip-file ? Comparing with my 2001 ver, it IMPORTs the extra module "Attributes", used in single statement: Attributes.SetBool( M.dlink, "Modified", TRUE ); What is the rule about contributors [NOT] modifying 'core' [or any existing] modules ? Are there any rules, or even guidelines ? Where are the [obviously existing] linux guidelines kept ? I'll ask on NewsGroups. Is there a better method of capturing/stealing a collaborative development METHODOLOGY than copying Linux's ? Or do ETHZ originated projects not need a proven methodology: they can just wing it ? Or is it taboo to discuss this ? == Chris Glur.

I will have a look at the problem tomorrow. BTW, at the moment I'm busy integrating WebDAV property handling in my DAV explorer. As you probably know, often it's easy to implement some functionality. What's taking blood, sweat and tears is a decent UI :-( Cheers, Edgar -- edgar(a)edgarschwarz.de, Running Bluebottle www.edgarschwarz.de Make it as simple as possible, but not simpler !

This is NOT one of them. The whole value of collaborative projects is that you can just write a rough-few-words and 'throw it out'. The next collaborator(s) can add some value to it, and throw it to the next.....etc. Hence via several steps of successive refinement, one uses division of labour [different persons have different skills/knowledge] and builds the product with minimum total effort. > I'm not done for writing documentation.
