OK, yes, OLR.Input.Mod is present and contains "CopyClip*, PasteClip*: PROCEDURE;". System.ShowCommands Input ~ gives Input.Copy Input.Paste . In the variant of Fedora, the OLPC XO system with X11, neither command produces a result. No evidence of data moved to or from the clipboard. One execution of Input.Paste killed the ./oberon process. Can have another look in Debian on Sunday or Monday. Thanks, ...

>From PeterMatthias at web.de Tue May 10 18:10:36 2016 > No "CopyClip*, PasteClip*: PROCEDURE; (* initialized in System *)" line > in the VARs section? Correct. At May 10 I did not find "CopyClip*, PasteClip*: PROCEDURE; (* initialized in System *)". Something fishy happening. This morning I purged the olr/ directory, retrieved olr160416.tgz again and installed again. No Input.CopyClip found. Is file name correct? Could the server be delivering an old file? Thanks, ...

At http://oberon.wikidot.com/start , retrieve and install olr160416.tgz. cd olr ; ./oberon # Try moving text via the clipboard. No success. # Read in http://oberon.wikidot.com/changelog . "2016-04-13: Added Input.Copy and Input.Paste to copy/paste to/from X11 clipboard. Input.Paste is called by pressing "Ctrl-v". For TextFrames, Input.Copy is called automatically when selecting text." View [olr/]Input.Mod with ET. No Copy or Paste procedures! I blundered in the installation? Input.Mod was not updated on wikidot.com as Peter M. intended? Anyone else tried Peter's clipboard implementation? Thanks, ...

ftp server at inf.ethz.ch

Hello people at ETH, In http://www.ocp.inf.ethz.ch/wiki/OCP/Downloads is the note "replace in all ftp links ftp.inf.ethz.ch/pub with ftp.ethoberon.ethz.ch". OK but I'm afraid that few novices catch that. A friend remarked "... lead to dead ends. Makes ya wonder..." Very odd to leave broken links indefinitely. Any chance of persuading IT staff to fix the links in the ETH Web pages? Regards, ...

Trouble with copy paste. Awkward feature comes in.
by Srinivas Nayak 06 May '16

06 May '16

I could never do the interclicks perfectly for copy paste. (May be because of non-Oberon habits) :-( I wish if I could integrate ctrl-c and ctrl-v feature from other Oberon version to my NO. The biggest trouble while doing copy-paste is, an awkward feature. Say, I have only one viewer, V1 opened in user track. I have to copy something from V1 to system log viewer, V2. I selected the word/phrase in V1, cursor is also seen in V1. I went to V2, did a ML. Cursor went to V2. If I do another ML at the same point, Cursor goes back to V1! Being curious, I did another ML, it comes to V2 again. With another ML, it again goes back to V1. And so on. What is the usefulness of this feature? With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

TeX & Oberon was: ETHO-plugin on Windows 10

Hi Srinivas, > >Do we have any module in Oberon to view or process Tex documents? > not really, although there is a Oberon-TeX in the contrib area of the orphaned Native Oberon download area: ftp://ftp.ethoberon.ethz.ch/Oberon/System3/Contrib/TeX/ I never tried to use it, but I had some deeper looks in it. As far as I can see it is a straight forward port and a kind of a fork. It does not use any of Donald Knuths nice features to do change management for Pascal dialects. It should/might be possible to tweak tangle/weave to produce directly Oberon from Knuths web sources (beware: Knuths web has not really anything to do with the world wide web and was created around 198, i.e. years before the www popped up, see also https://en.wikipedia.org/wiki/Literate_programming) -- Bernhard
