But, we can still find another name if wanted, just not workspace. For example, it can be something about starting, or entering a space. I would also prefer having something that ends with an "er" or "or" like the Inspector or Debugger. it meets what people would expect and > no books would have to be rewritten ;) > I disagree again.

You can also commit either in your own repository and send us a ping. Because of the optimistic approach, it is better to have a discussion beforehand, either through an issue or via the mailing list. When we are all happy (it can be that a change is reverted), we create a new stable version that afterwards has to be integrated into Pharo. I believe that after a while, we should eliminate the last step and have Pharo integrate the latest stable, but we need a transition period.

Btw, this is how Zinc was handled since quite a long time, and we want to move Pharo to be handled via configurations in separate repositories from now on. This is a way to scale the effort by not making the central team responsible for everything. Cheers, Doru > Thx > T. > > -- www.tudorgirba.com "Every thing has its own flow"

Wow, this is an interesting stuff. Is this a kind of desktop manager written on Pharo? From what I can see on video it support calling external processes like open-office. Does it work on Pharo 3.0 ? -- View this message in context: http://forum.world.st/PharoNOS-tp4784982p4785054.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] PharoNOS

by mikefilonov

Hi Phil, I would really happy to know if this works for you. Considering this use case in mind do you have an idea how PharoNOS should handle the Image? Should it be embedded in ISO or should it be configured from clean Pharo on each device? For instance, if it is really useful we can have a server which would re-build the ISO with a requested image. What do you think on this? -- View this message in context: http://forum.world.st/PharoNOS-tp4784982p4785039.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Rectangle differences between Pharo 3 & 4

by Ben Coman

I notice a difference between Pharo 3 & 4... Rectangle left: 4 right: 3 top: 2 bottom: 1. Build 30856 --> (4@2) corner: (3@1) Build 40309 --> (3@1) corner: (4@2) Rectangle origin: (4@1) corner: (3@2) Build 30856 --> (4@1) corner: (3@2) Build 40309 --> (3@1) corner: (4@2) I remember some report of Stef and Igor fixing some Rectangle stuff, but I wasn't paying attention in detail. Is this related? What is the intent? I noticed this reviewing the some tests added by mschepens https://pharo.fogbugz.com/default.asp?14221 It seems now there is an assumption that rectangles always go from top-left to bottom-right. I wonder what would be the effect (in a hypothetical application) if I am dragging a rectangular "rubber band" (as is commonly done for selection in graphics programs) and I move the secondary/corner point of a rectangle up and left of the first/origin point? Would it be correct to say that Points and Rectangles are immutable, and so maybe its not a problem, such that a "rubber band" selection would be creating new rectangles each mouse move? btw, Rectangle left: 1 right: 2 top: 3 bottom: 4. Build 30856 --> (1@3) corner: (2@4) Build 40309 --> (1@3) corner: (2@4) cheers -ben

Re: [Pharo-dev] PharoNOS

by mikefilonov

I'll take a look at AioPlugin issue. How I can test if it is loaded well? The ISO process can be easily automated. If the PharoNOS is really needed I'll run CI somewhere :) May be we could think of a way not to package the image but somehow fetch it after start? It could be a script which downloads an image requested and reconfigures the startup.

Re: [Pharo-dev] PharoNOS

by mikefilonov

Hi Torsten, Yes sure I can. So this PharoNOS is basically TinyCore Linux with pure X server and Pharo running in fullscreen. I have made some auto-installation scripts which configure the disk so no setup wizard is needed. All space available is mounted under /mnt/universe/ so you may use that folder to store stuff. Everything else is stored in memory. Nice side effect of this is an ease of update as you may just replace the ISO and you'll get the new version of everything (except of the image of course). Image is chosen on start by reading the "/mnt/universe/image" file. You may upload other image and change this file so after reboot it will start with a new one. No safeguards here though - if it breaks there is no cure for it yet :( I'm thinking over on how to implement some recovery on "Image not available or broken". Hm, just now get the idea to run Image chooser if default image failed. Is it available on linux? Jan Tomsa has pointed out that the disk setup is quite dangerous (https://twitter.com/DetektivTomy/status/522860736155238401) I plan to update it later today with more safe solution which will not erase all the data.
