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...

Chris, cg> filter/modify the data to be as the 'consumer' wants, ... In this case, filter = PSPrinter.Mod and consumer = "LaserJet III with PS cartridge". Hours after submitting the story to the list, the possibility of configuring in Oberon.Text dawned on me. One of these might be workable. PSPrinter = { ... TerminateWithControlD } PSPrinter = { ... TerminateWithControlD = True } This would be a "study" for me. Would be prudent to have the approval an expert before wasting time. Many such small repairs and improvements must have surfaced since the last alpha, 2003-01-05. SSH and PPP for example. I wonder whether a new alpha might be worth considering before the beta or full release is ready? (Not that I know how to build.) Regards, Peter http://carnot.pathology.ubc.ca/

Use the unix approach: filter/modify the data to be as the 'consumer' wants, instead of reprogramming the 'consumer'. Here's a case where this cheap hack approach is not possible: n-o's email client (ver 2001, falsely: because it's not in the RFC) assumes that the server's data will be some thing like: "you have 9 messages", and accordingly extracts the first interger value from the received data, (char-string) at this stage. So when eg. the server says: "NovellNet ver 3.0.4b ...", the client falsely sets-up for 3 messages. == Chris Glur

The 'authority' [before partition facilities existed] is that: ] an Oberon file name consists of the letters A to Z ] (upper or lower case), the digits 0 to 9, and the period ".". Now [version 2001] ab:c and ab:c:d show: "invalid name" on attempts to store, which confirms the syntax. So SYS:dog is NOT a valid 'file name' by the above definition. "SYS:" is the partition name and "dog" is the filename. Looking at my 2001 version of Compiler.Tool :- ] Ox prefix output .Obj file with x I guess the idea is to be able to create eg: Ver3<name>.Obj from using Compiler.Compile \O Ver3 * where the <name>.Mod frame is marked. The intention is NOT to pre-ppend partition identifiers. And if it did create SYS:<name>.Obj , that would be an unintended consequence. I don't feel like testing it. Remember that the partiton facilities were developed independent of the compiler. One would hope that the partition facilities would be orthogonal to compiler facilities. They seem to be gathered in OFS.Tool ? > Would also be nice to mention the distinction between > an option applying to one file in a list and an option > applying to all files. This doesn't apply to Compiler.Tool ? What kind of operations are you refering to ? It's starting to look like linux's 'make & makedev'; now there's a can of worms ! == Chris Glur

Oberon readers, There is a LaserJet III here with an HP PostScript cartridge and PSPrinter is installed in ETH Oberon / PC Native 05.01.2003. A test page prints correctly but then "PROCESSING DATA" continues until "PS ERROR 16". The _PostScript Cartridge User's Guide_ explains the error in section 5.8.b. Quoting briefly, "The control-D must be the last thing sent to the printer." I don't really understand the need for the control-D. Apparently the newer printers at the ETH don't impose this requirement. In any case, I added the second of these three statements in PSPrinter.Close. Files.WriteBytes(printR, buffer, bufSize-srcR.res) UNTIL srcR.eof; (* End-of-file signal for a LaserJet III with an HP PostScript cartidge. *) IF ~P.eps THEN Files.Write(printR, 4X) END; (* P. Easthope, 2004-04-29. *) IF ~P.anonymous THEN Printer.Spool(P.printF) END; A few additional points remain. 1. My understanding of PSPrinter.Mod is cursory. Is this repair appropriate? Is there a case where it will fail? 2. Can the decision to insert "4X" be automated by probing or querying the printer? Otherwise the user must diagnose the problem and recompile PSPrinter. This is beyond a novice and is inconvenient at best. 3. If the repair can not be automated, the additional statement should be supplied in the distribution, commented out. Also it should be mentioned in http://www.oberon.ethz.ch/printer.html . Regards, Peter E. http://carnot.pathology.ubc.ca/

I don't use the compiler often enough to remember whether ":" is inserted automatically between SYS and filename or I need to put it there. Seeing as how \P refers to path rather than partition, I understand ":" not being inserted automatically. Nevertheless, this example in Compiler.Tool helps. Compiler.Compile \OSYS: * Would also be nice to mention the distinction between an option applying to one file in a list and an option applying to all files.
