[Pharo-project] STDIO on Win
by Torsten Bergmann June 4, 2012

June 4, 2012

Hi, havent yet played with the latest stdin/stdout stuff. Does this already work on Windows? At least I tried FileStream stdout nextPutAll: 'Yopla' in the latest 2.0 after starting Pharo-2.0-one-click.bat. Gives an error (write failed). Any comments?

[Pharo-project] What i would like to have instead of progress bar
by Igor Stasenko June 4, 2012

June 4, 2012

If you would ask me (yeah nobody asking me, by i will tell anyways ;) ) how the indication of a progress of some process should look like, here's my potential answer: - a tiny one line in a corner of desktop (instead of huge banner centered in window, sticking on top of everything and obscuring the view) - not blocking user input - no stupid nesting.. i don't care what happens inside of something else happens.. if it is really necessary, i would just replace the title of a task with it's subtask title while it performing. this is just about first rule: it has to be a single line, not a bunch of lines stocking one over another.. i think this is abuse. most of the times, i just need a notion of progress of a whole thing, not progress of it's subthings (if user really wants, he can hover the mouse over progress line to see the details, but by default it should take minimal space on the screen). -- Best regards, Igor Stasenko.

[Pharo-project] mixing open and closed source within Pharo
by Ben Coman June 4, 2012

June 4, 2012

What ideas are floating around about mixing open source and closed source using Pharo? I am implementing an IEC Standard object model for electrical power systems to provide a platform for developing electrical applications. I am considering the case where a company may maintain the model of their electrical power distribution network in the open source platform, but then buy various commercial plug-ins perform different calculations upon the shared model. Here are the options I can imagine... 1. Using fuel to load binary packages within the one image without the source. Currently available technology but viewing and decompiling bytecode is still possible - but to what degree this enables reverse engineering I am not sure. 2. Having VM support for restricting displaying/decompiling bytecode. To avoid the ease of switching to another VM without this restriction, the fuel package could be encrypted with a key match one compiled inside the required VM. 3. Running multiple images on a single VM such that the VM passing message calls efficiently between the two images like an "enterprise bus*" - one open source and one closed source. Any common base objects between the images might be shared on a copy-on-write basis. What are your thoughts? cheers -ben

[Pharo-project] McHttpRepository and text/plain
by Stuart Herring June 4, 2012

June 4, 2012

Hi all, I recently ran into the problem with a server returning text/plain instead of application/octet stream again (see http://lists.gforge.inria.fr/pipermail/pharo-project/2012-April/062388.html) but the resulting error (a MNU for Character>>bitOr:) failed to job my memory as to the actual cause. Is there any chance the final line of McHttpRepository>>readStreamForFileNamed:do: could be changed from: ^ aBlock value: contents readStream to: ^ aBlock value: contents asByteArray readStream I know that it would be best if Web Servers never served up binary content as text/plain - but it's not always in the power of someone who encounters this error to fix that. Failing that, the condition should probably be explicitly checked for and a more useful error message given, as the cause is far enough away from the symptom that it takes a bit of digging to find out what went wrong. Regards, Stuart

[Pharo-project] Some steps towards headless on OS X
by Mark Smith June 3, 2012

June 3, 2012

Hi all, The underlying problem with headless mode in OS X seem to be that we always create a window, even when we run in the background, as we do in headless mode*. Marking the process as background only will remove the icon, menu etc. but it will not stop us from creating that window. Maybe I don't know enough about how Squeak/Pharo works right now but it looks like quite a lot of work to change this. And the code isn't pretty ;). Anyway I'd like to keep working on this but I've hit a wall. I can handle the Cocoa side but don't know anything about the VM's setup process etc. Could someone clarify this? Or maybe there are some docs? Also â What do you guys think about building a headless VM without any of the UI stuff in it? It might be simpler/cleaner than what we have now. All the best, Mark * Creating the window is almost the first thing we do! We do it before we know if we're running headlessâ¦

Hi guys In 20, which T1>>m1 is defined under cat1 when we do T3 uses: T1 T3>>m1 is 'as yet unclassified' and this breaks several tests. Any idea of a change that could have modified the system? Stef
