Source code browser in NO

Dear All, Do we have any source code browser in NO? I see we have Definitions browser in NO. Using Watson, if we create *.Def and *.Def.html, we can browse through Definitions. Anything similar for source code? With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

Re: [Oberon] Concurrency support in Oberon
by John R. Strohm 25 Nov '16

No, Oberon has no concurrency support in the language. The Oberon system provides a simple event loop, that allows programmers to do simple round-robin run-til-done scheduling. --- sinu.nayak2001(a)gmail.com wrote: From: Srinivas Nayak <sinu.nayak2001(a)gmail.com> To: ETH Oberon and related systems <oberon(a)lists.inf.ethz.ch> Subject: [Oberon] Concurrency support in Oberon Date: Thu, 21 Jan 2016 20:27:05 +0530 Dear All, We had Pascal, We came to its successor Modula-2.

Oberon-07 is an ideal language for developing embedded applications. I'm not sure what you mean by 'preferred platform'. The Arty (Artix-7) and the Pippistrello (Spartan-6 LX45) development boards are the only two I have found so far that have sufficient BRAM to run embedded ProjectOberon without external SRAM. Saanlima's Pippistrello is about $50 more than the Arty. However, the Pippistrello does have a built-in SD Card socket and can also be used as an ProjectOberon Workstation development system with Saanlima's optional Oberon SRAM 'Wing'. There are many simpler FPGA boards available but all the ones I have found use less-capable FPGA devices with insufficient BRAM. The Arty and the Pippistrello have more features than are needed for embedded Oberon applications like those on the ARM Cortex-M3/M4 boards that we support. However, I guess that doesn't matter for those who are designing their own boards and just want an off-the-shelf reference system to use for prototyping / proof of concept. If on the other hand you want to run the complete Project Oberon 'workstation' system with VGA / HDMI, keyboard and mouse. You will need a board with external SRAM like the OberonStation. An Arty would not be suitable for this purpose. > Finally, and perhaps best addressed to Chris Burrows - I see that > you have produced packages for the ARM M3 and M4 Cortex - mainly NXP. > Do you have any aspirations to port to Cortex M7 - such as the $50 > STM32F7 Discovery Platform - which has a great selection of useful > hardware on-board? > There used to be an clear distinction between the simple 8-bit microcontroller at one end of the spectrum and the 64-bit PC at the other. In recent years the two have started to converge. The embedded systems are becoming more powerful; the PCs are becoming smaller and less power-hungry - the distinction is blurring. The STM32F7 Discovery Platform seems to me to be more a miniature PC than a high-power embedded system. While we remain focused on supporting embedded systems we are unlikely to be targeting it, Regards, Chris Chris Burrows CFB Software http://www.astrobe.com/RISC5

Wikibook _versus_ svn or git.

Hi, A small discussion about the possibility of a wikibook for the sources for the Oberon system is here. https://en.wikibooks.org/wiki/Wikibooks_talk:What_is_Wikibooks#The_source_c… I began the discussion out of interest. Certainly I don't claim to have any convincing answer or solution. Comments here or on the Wikibook page are more than welcome. Thanks, ...

Oberon language family and the master.
by Srinivas Nayak 05 Sep '16

Dear All, I am referring to http://www.oberon.ethz.ch/archives/languagearchive/genealogy. Here we see that Oberon language from its birth has gone through several revisions. Many times either NW or others have added new features to it if they feel a need of it. Or removed existing features, if they found it unnecessary. After all these iterations, Oberon might have got time tested. So today, can we say, whatever is present in Oberon-7 is time tested; and one doesn't need to add or remove anything from it; and this is the state-of-the-art; and is simple but not simpler? If so, one wouldn't worry about Oberon V, Oberon X, Active Oberon, Action Oberon, Object Oberon, Concurrent Oberon etc. etc. With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/

Global font change on OLR

oberonstation vs. a $9 computer
by skulski＠pas.rochester.edu 14 Jul '16

Lars: It is sort of funny that one can use the low price as an argument. How much do you value your time? Let's say it is $5 per hour, way below minimum wage. How much time will you spend on getting anything done with any piece of hardware, be it Arduino, RPi, Beagle Bone, or Oberon Station? Are you going to achieve anything meaningful in less than 10 hours? If so then I will consider hiring you for $50 per hour. The low price does indeed matter if you will use the hardware in a finished product. They are talking of a disposable computer. If you are going to basically throw it away after a single use (provided that you environmental soul lets you do it), then indeed $9 matters. But if you are going to do any development or experimentation with the HW, then you will likely spend hundreds of hours doing so. Then it does not matter if you invest $9, $90, or even $900 into your hardware. Almost any such amount is dwarfed by the cost of your time. Oberon Station is a development platform. The valid question is "development of what?". The initial dollar investment in the development hardware is not that important in this case.

ftp server at inf.ethz.ch

At http://lists.inf.ethz.ch/pipermail/oberon/2016/009504.html Peter Easthope asks whether ETH IT Staff can be persuaded to fix broken links. Does anyone know who specifically should be contacted? I have not yet been successful at contacting the proper people. As yet no one has responded to several emails I've sent directly to ocp(a)inf.ethz.ch. (Dr. Friedrich did respond to a couple messages I sent to him, or on which I cc'd him.) At http://www.oberon.ethz.ch/contact/index three names are shown. Email sent directly to those addresses returns "User unknown" errors. I have also just now tried to use the "Feedback" form on that page, and will wait and see if anyone responds. A concern I have regarding asking to have the links fixed, is that they may instead decide to shut down the server entirely. Have key people on this list already captured/saved the important items currently hosted at www.oberon.ethz.ch, in case they shut it down? I've captured most of the items on the ftp site, but have not triple-checked that I got everything. I don't know what I'm missing from the web site. -- John Roberts
