Peter Somebody must have edited Hotkeys.XML as the original that comes with the A2 distribution assigns F12 to System.Free Hotkeys not SystemTools.Free Edit it back and press F12 before starting Oberon. br Jörg > Am 03.12.2023 um 21:56 schrieb peter(a)easthope.ca: > > Joerg & all, > > From: Joerg <joerg.straube(a)iaeth.ch> > Date: Sun, 3 Dec 2023 13:21:26 +0500 >> Does this error appear while booting Oberon? > > Happens while the Oberon subsystem is running.

Then I press F12, which HotKeys should assign to disable itself. That invokes "SystemTools.Free HotKeys". In absence of SystemTools, an error occurs. =8~/ Should SystemTools be in the system or not? While that is ambiguous we can't expect an internally consistent system. Aside from that, the star-shaped marker is essential to the interface of the Oberon subsystem. I commented out the three lines in HotKeys.XML which assign A2 usage to F1 and F2. Commenting out the lines doesn't help. F1 still doesn't set the Oberon star marker.

Re: [Oberon] Startup configuration of git-based A2.

>From Soren Renner soren.renner at gmail.com, Sat Nov 25 21:39:06 CET 2023 > i would also like to know about this [personal configuration of A2] These are the best ideas I have. (1) Keep a copy of the distributed Configuration.XML. Eg. cd <somewhere>/A2GitArchive/data cp Configuration.XML Configuration.XML.9799 9799 is the revision number. Then Configuration.XML can be edited to taste and backed up in the working directory. Sooner or later, git many update Configuration.XML. In the past, some revisions of Configuration.XML have been essential for A2 to run. Compare a revised Configuration.XML with your customized version. Eg. in Oberon, Diff.Do <somewhere>/A2GitArchive/data/Configuration.XML Configuration.XML (2) A2 has System.DoFile() analogous to ET.Do in ETH Oberon. Your working directory can have file myStartupCommands and the Autostart section of Configuration.XML can have this line. <Setting name="My startup commands" value="System.DoFile '<myWorkingDirectory/myStartupCommands' "/> That adds only one line to Configuration.XML. (3) Earlier I mentioned .../data/Configuration.XML being a link to <myWorkingDirectory>/Configuration.XML. Workable. It's a question of preference or taste. Better ideas is always welcome. Thx, ...

Representation of Latin Small Letter U with diaeresis in a source Text and a text.
by peter＠easthope.ca 25 Nov '23

25 Nov '23

Hi, Most source Texts and source texts which originated at ETHZ begin with a line similar to this. (* ETH Oberon, Copyright 2001 ETH Zuerich ... I've seen at least three representations of "Latin Small Letter U with diaeresis", as Unicode describes it. (1) "ue" which Europeans might consider a kludge. (2) "ü" which a hexadecimal editor displays as FC. According to Wikipedia, this is from the "C1 Controls and Latin-1 Supplement" of Unicode. (3) "ÃŒ" which a hexadecimal editor displays as C3 BC. A Microsoft encoding? (4) "&#uuml;" the character entity reference of Unicode. How do Europeans prefer to see the accented characters represented in an Oberon Text and in an ASCII text for a source of an Oberon system? Thanks, ...

Startup configuration of git-based A2.
by peter＠easthope.ca 25 Nov '23

25 Nov '23

Hi, For Guenter's A2, I kept customized Configuration.XML and Oberon.Text files in my working directory. Today I have the git-based A2 working in Debian 12. Configurations are GitDirectory/data/Configuration.XML and GitDirectory/data/Oberon.Text. Configuration files in my working directory are not effective. That allows revision of configuration via git but I wonder about incorporation of my customizations. data/Configuration.XML and data/Oberon.Text might become links to my customized versions although that will complicate updates from git. Suggestions? Thanks, ... P.L. -- VoIP: +1 604 670 0140 work: https://en.wikibooks.org/wiki/User:PeterEasthope
