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

Version control
by Felix Friedrich 01 Jun '03

01 Jun '03

Hello everybody, I have a problem that probably most of you would consider as "standard" but, still, I have no solution. I have been an Oberon programmer since some years now and have been working in cooperation with other people, we have written some packages together and up to now did the version control by hand, i.e. mainly by oral agreements. Now I am confronted with the situation that more and more people are working with some of the modules and sometimes extend them or correct errors or simply add new capabilities to them. More or less regularly I have to synchronize the versions which will become a problem soon since even more of us are becoming Oberon users. Does anyone of you have an automatic version control for Oberon (with logging in / out etc.)? Or maybe some of you can write some practical experience with Oberon-Version control? We are working with the PlugInOberon under Windows, the Linux-Version and (still experimental) with Bluebottle.

In VCSBase and DAVDeltavBase I'm using Oberon Texts which aren't available on Bluebottle. So I sort of "bluebottled" them. On ketchup:FAT:/es/httproot/dav you can find es.DAVObjects.Mod, es.DAVFonts.Mod and es.DAVTexts.Mod which especially don't depend on Native Files any more. I'm not sure but perhaps this could be useful to you.

painfull edit/compile/run cycle !
by eas-lab＠absamail.co.za 28 Feb '03

28 Feb '03

Now I remember why I considered n-o edit/compile/run cycle very non-productive. How do I identify a module's callers, so that I can System.Free <client-list> , instead of rebooting for each edit/compile/run cycle ? Thanks for any help. -- Chris Glur.

Edgar, es> BTW, sometimes I wonder how many people on the world are using Native PPP? Probably it's just Chris, Peter and me ... As Chris has mentioned, many potential users must abandon it when the first snag is encountered. The worst deficiency I am aware of is the lack of negotiation of DNS addresses. (Described in detail in my PPPnotes for anyone iterested.) Thanks for your tireless efforts Edgar. Certainly they are appreciated by anyone who uses your software.

WebDAV.0.6.1.Zip
by Edgar＠EdgarSchwarz.de 27 Feb '03

27 Feb '03

Hello, just to show that WebDAV is evolving, a minor release. If you are interested have a look at "http://www.edgarschwarz.de/oberon/" or get it directly at "http://www.edgarschwarz.de/oberon/WebDAV.0.6.1.Zip". Change Log: - More XML responses are parsed to make them more readable. - More server side error messages. I will stay silent concerning PPP for the moment because I don't have much time. But I hope to be able to provide WebDAV Versioning for PPP on a Bluebottle server in some weeks. BTW, sometimes I wonder how many people on the world are using Native PPP ? Probably it's just Chris, Peter and me :-)) The foundation would be my last release followed by Peter Easthopes improvements. And as soon as XML for Native is working (I'm optimistic yet) a client could also be made available for our friend Chris in South Africa :-) Cheers, Edgar -- edgar(a)edgarschwarz.de "http://www.edgarschwarz.de" "http://www.edgar-schwarz.de/forum/oberon" Running Active Oberon Make it as simple as possible, but not simpler.

PC.Compile singularities
by rotaru＠centrum.cz 27 Feb '03

27 Feb '03

Hi, this is a rather minor problem, but anyway a) If you use objects in texts of your programs the error reporting (PC.Compile) gets confunsed. The problem seems to be in PC.TextReader.Receive procedure in this lines. REPEAT Texts.Read(r, ch) UNTIL r.eot OR ((r.lib # NIL) & (r.lib IS Fonts.Font)); the objects are just discarded, which is fine, but the "char index" does not increase, so you get the errors reported before their actual position. I have changed those lines with Texts.Read (r, ch); IF r.eot OR ((r.lib # NIL) & (r.lib IS Fonts.Font)) THEN (* regular char or end of text, do nothing *) ELSE (* some kind of object, give the compiler a space instead *) ch := " "; END; (* if *) and it helped. b) While testing the previous change, I have run into this. MODULE See; TYPE A = RECORD a : BOOLEAN (* semicolon missing *) l : LONGINT; END ; END See. It compiles with PC.Compile, which is not rather problematic. Regards V.

(Re (3): [Oberon] PPP ...) & syntax of PPP
by peter_easthope＠gulfnet.sd64.bc.ca 26 Feb '03

26 Feb '03

Chris and Edgar, cg> Up to V2.3.6 the PPP was 'removed' (together with the dialer) when the dial up session was completed. Perhaps now the designer(s) want to cater for 'persisitent connections' ? This would allow the error of PPP 'not resetting' to show. Previously the 'PPP.Stop' for dial-up termination, forced a clean-up. Chris, you refer to fundamental features of the mechanism. In an ideal world the designer specifies these before implementation and then makes revisions as the design evolves. At present we do not have such specifications for PPP. Edgar is best qualified to write them but if he does not have the time I suppose you and I are next in line. In this case, the best we can do is to study the sources, write a tentative specification of behaviour and make corrections as we become aware of errors. Anyone interested in the syntax of PPP, In _The School of Niklaus Wirth_, Pub. Morgan Kaufmann, 2000, p. 107, Jurg Gutknecht gives an EBNF description of the Oberon file transfer protocol. When time is available I want to attempt such a description of PPP. Gutknecht shows the local syntax in plain text and the syntax from the remote system in italic text. For electronic distribution, a notation based on displayable ASCII characters seems preferable to italicization. Text from the remote system could be enclosed in <...> or _..._ for example. Perhaps some experts in EBNF can address this issue and suggest a notation. Thanks, Peter E. http://carnot.pathology.ubc.ca/

load statement in Scheme Library
by peter_easthope＠gulfnet.sd64.bc.ca 26 Feb '03

26 Feb '03

Oberoners, In Vinci.Text under "Appendix B - Scheme library" is "load(string) read expressions and definitions from file with given name any". I have a Vinci script containing load("Dimension.Vinci"); as the first line. Interpretation of the script yields an error message indicating that the functions defined in Dimension.Vinci are not available; I concluded that Dimension.Vinci failed to load properly. If Dimension.Vinci is loaded by "VinciDocs.Open Dimension.Vinci" then subsequently the functions in Dimension.Vinci are available to another script. I wonder whether load needs a second argument; ie. whether "load(string)" is correct in Vinci.Text. Does anyone have enough understanding of Vinci and Scheme interpretation to help with this? (After an hour or so studying Vinci.Mod and Scheme.Mod I have only very sketchy ideas.) Thanks, Peter E. http://carnot.pathology.ubc.ca/
