Receiving Nautilus notice when code is changed

by Hilaire Fernandes

Now I wonder how can I get noticed when code was edited and compiled from a Nautilus window. Previously I was doing: browser addDependent: self domain. and DrGeo received notice in the domain objet through the #update: method. It does not work anymore. How to do it now?

Plus, you mention you're coming from Dolphin Smalltalk. Which is easier than the average, in terms of straightforwardness. Pharo has A LOT to offer, once you get used to aim at a moving target :) Esteban A. Maringolo

Stephan Thanks for the comment. I understand the point about development and things not always being in step. But if you look at it from my point of view, I am an elderly retired statistician who does programming for fun, I am not an expert in development and I am pretty new to Pharo. It all looks a maze of new terminology to me - I don't understand the difference between Monticello and Metacello, for instance. I am sure to an expert your explanation of how to check the correct version of Magritte3 is quite straightforward, but I would never have found my way to that conclusion myself. As I pointed out to Esteban, I used the configuration browser on 5 May to get the stable version of Magritte3. If that was already out of date, I am pretty well lost. Still, I am making progress with my original aim of learning about Magritte, and there are many helpful people on this group, so you can just regard this as me blowing off steam after things had not gone completely easily.

Re: [Pharo-users] Problem learning about Magritte

by PBK Research

Esteban Well I don't have /such/ an old version. As I said, I downloaded the new Pharo 3.0 on 30 April. On 5 May I opened the configuration browser and loaded ConfigurationOfMagritte3. So presumably what I have is at most 9 days old. One of the frustrations of using Pharo is that everything seems to be always changing. I have in fact sorted it out by looking at the Forum image, following Stephan's suggestion. There I found that the call to RectangleMorph class has become BorderedMorph, and when I change that it all works. I now have an editor window which will change the instance, so I more or less understand how to use it. I still can't get it to produce an editor in a browser using Seaside, but that is less important.

you have an older version (configuration is probably not up to date)â¦ just open project in monticello and load latest magritte-morph, it should work. and yes, I use it all the time :) Esteban On 14 May 2014, at 12:00, PBK Research <peter(a)pbkresearch.co.uk> wrote: > Stephan > > Thanks.

Re: [Pharo-users] Problem learning about Magritte

by PBK Research

Stephan Thanks. I have Magritte-Morph in my image, but I wonder if anyone has debugged it. I send asMagritteMorph to a Magritte description and I get a MAContainerMorph, which is OK. Try sending openInWorld to this, and it falls over in MADescriptionMorph>>buildMorph, which calls MADescriptionMorph>>rectangleMorph, which tries to create an instance of the non-existent class RectangleMorph. I have tried to trace this back, and it is true that my original Pharo 3.0 image, downloaded on 30 Apr 2014, does not have the class RectangleMorph. I have looked at older images, and the class exists. Maybe my mistake was to try to use the Pharo 3.0 image the day it was announced. Perhaps I would be better off using one of the pre-packed images you mention. My only worry is that there is a list of dozens of contributions on https://ci.inria.fr/pharo-contribution/, and unless you have far more knowledge than I have it is impossible to know which might be helpful. For now I will follow your hint and use the Forum image. Thanks again for your help.

Migrating to Nautilus

by Hilaire Fernandes

Hi, In DrGeo, I add this code snippet to: browser := Browser newOnClass: DrGeoUserScripts selector: mathItem script. browser addDependent: self domain. browser codeTextMorph owner owner extent: 450@350. browser topView setProperty: #morphicLayerNumber toValue: 5. 1. open a minimal browser 2. set a dependency so DrGeo is noticed when the user edited and compile its script (so Drgeo can update the sketch) 3. rescale the browser so the user can still see his sketch 4. set the minimal browser in a permanent top position. As Browser is broken and not gonna be fixed, I need to redo the same with Nautilus, but this one is a big beast. Any tips how to do it? Thansk Hilaire -- Dr. Geo http://drgeo.eu
