[Pharo-project] Nautilus and Keymappings new bes friends?
by Mariano Martinez Peck Feb. 20, 2012

Feb. 20, 2012

Hi guys. OB has its own way of managing shortcuts and I imagine it can be a little bit difficult to customize or add shortcuts to a browser. Now that: 1) we have KeyMappings working very well. See: http://marianopeck.wordpress.com/2011/12/04/why-keymapping-rocks/ 2) we have Nautilus written from scratch 3) Guille will probably come to Douai for a Phd (1hr far from Ben) 4) Ben already included refactoring integration ;) I see a really great possibility that we should not miss. Smalltalk was already quite related to the mouse and I hate the mouse. I know that the text editor is not responsibility of Nautilus, but at least, I think that the browser could be improved MUCH more regarding shortcuts.

[Pharo-project] garbage collection
by Milan Mimica Feb. 20, 2012

Feb. 20, 2012

This is more of a GC theory question perhaps, but I do have practical problems, so: I'm trying to figure out how come my headless Pharo 1.3 image with fairly recent Cog running Magma ran out of Semaphores. I know there is a fixed limit on number of semaphores Cog can handle, and only Magma and RFB server have been running on this image for two months, and there wasn't any heavy load whatsoever, so something must be leaking semaphores - or more likely - something must be leaking objects having reference(s) to semaphore(s). I am not leaking sockets btw. At the moment there is about 1400 instances of Semaphore class, and around 400 after GC. So first question is: Suppose I haven't run GC manually, could the semaphore limit be hit? 400 is still too high for a idling image, don't you think? Anyway, what I try next is to shut down Magma completely and try to clean the memory by hand. I notice some MaServerSockets are still floating around so I track the pointers and I find that all the references are circular! Question two: Does Pharo's GC solve circular references? If yes, how good is it at it? But then, thinking more about it, the whole running image is one big graph of circular references, you wouldn't want the GC to clean that :) So how does it really work? That's my naive view anyway. After I wrote all this I figure I'm better of taking a fresh new image and load what I need into it, even if I have to do it every two months. Not saving the image is also an option. Yeah, I think I'm going to do just that. I found my solution, at least this e-mail served for something. Since I don't have a blog I'll send it anyway. -- Milan Mimica

With Pharo and its ecosystem you can build powerful tools (web application, data management, business processesâ¦). Â Pharo philosophy is driven by domain driven design. Modeling is agile.

[Pharo-project] Updated Pharo HTTP Server Single Command Line Demo
by Sven Van Caekenberghe Feb. 20, 2012

Feb. 20, 2012

I updated my Pharo HTTP Server OneCommandLine Demo for 1.4 http://forum.world.st/Pharo-Core-HTTP-Server-OneCommandLine-Demo-td3702218.… How easy and how fast can you download, install and start an complete Pharo based HTTP Server on a bare Linux machine ? It just takes One Single Command Line: $ curl http://zn.stfx.eu/zn/pharo-server.sh | bash In well under a minute, you can browse http://localhost:1701 and all this with less than 20Mb being downloaded. Enjoy, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Script for building 1-click images
by Martin Sandiford Feb. 20, 2012

Feb. 20, 2012

Hi Folks, In the hope that it might be useful, I've somewhat tidied up some scripts I've been using to build 1-click images from Jenkins and uploaded to github. Nothing much to the script, but hoping it might ease the burden for whomever is doing this by hand at the moment. Git repo is here: https://github.com/msandiford/mk1click Cheers, Martin

[Pharo-project] Marking methods
by Bernat Romagosa Feb. 20, 2012

Feb. 20, 2012

Hi list, I've been thinking for a while that it'd be great if we could somehow graphically mark methods in the browser. Like adding an icon next to their name or highlighting them in different colors. When reviewing code, I find myself going through methods and would love to be able to mark them once they've been reviewed, to prevent me from going through them again. Does anyone else have the same needs? How do you guys manage this? I thought about flagging methods, but that'd mean I'd have to read through all my methods again to remove the flags once I'm done with the revision. Cheers, -- Bernat Romagosa.
