funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Help (perfect for newcomers) migrating a technical FAQ
by Mariano Martinez Peck April 9, 2011

April 9, 2011

Hi folks. I had a good idea and and it perfect for someone that wants to help and don't know how. It is not the most entertained task, but I promise you will learn a lot. Mostly, if you are newcomer. The idea is basically to migrate the FAQ that is here: http://scg.unibe.ch/wiki/faq/pharofaq to a new section in the collaborative Pharo book: http://book.pharo-project.org/ So....any takers ? Let us know so that we generate a new user in the Book The idea is also to check whether what is says is still correct for pharo or if it needs an update. Or even how to improve it (from the view of a newcomer). Thanks Mariano

Another Halo Question (complete newbie)
by James Ashley Nov. 3, 2010

Nov. 3, 2010

How-dee! I'm working my way through PBE (no, I've been too broke lately to buy a copy yet *blush*, but I will) and a few other smalltalk tutorials. I've read the documents about getting halos activated in the first place. I'm on linux, where alt-shift middle-click (I'm still trying to get the button colors down) generally works. In the lights out sample, it doesn't. I can ctrl-shift "left" click, get a giant menu, and select "Add Halo." That puts a halo around the individual cell. If I close it, it disappears and shows a blue background (which I'm starting to suspect is a default for morphics...is that close?). If I jump back through the "Add Halo" hoops on that background, or actually manage to click on the border, I just get what seems to be halos for the desktop (system? background? It's always frustrating to start learning a new system and not know the terminology...then again, that's part of the fun). I've been able to close the morphic by adding a "self owner delete" mouse down handler to the cells, then commenting it out until I need it. But it's more than a little painful. I spent about two hours today googling for variations on "morphics decorated frames", but the results I got suggested that I'm not even in the ballpark. I'm sorry if I missed an FAQ or didn't dig far enough back in the mailing list archives. Thanks in advance, James

Re: [Pharo-users] How to detect an inactive image?

IF you get some answers I;'m interested to know it because we are thinking about what is a VM API to monitor them. > At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser.

I would like to shutdown images if they aren't accessed for some time. > I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside.

How to detect an inactive image?
by Norbert Hartl Oct. 29, 2010

Oct. 29, 2010

At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser. For persistency I use piers image based persistency. But I don't want to have all of the images run all the time. I would like to shutdown images if they aren't accessed for some time. I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside. What is a good measure of activity inside the image? thanks, Norbert

Activating Halos around morphs
by Daniel Klein Oct. 24, 2010

Oct. 24, 2010

I'm new to Pharo and I'm going through the PBE book (yep, I bought it). I'm using the image that goes with the book on Windows XP Pro. I can't get halos around any morphs and I don't see a setting in the Preferences browser (I notice this was changed to Settings in later releases). I tried evaluating Preferences enable: #halosEnabled but it had no effect. Interestingly, I can get halos around the the World menu with alt+left-click, but once I pin it, I can no longer get the halos. What am I missing? Daniel Klein
