SODD

by Yuriy Tymchuk

Hi, so this message is about SODD (Stack Overflow Driven Development) and Pharo/Smalltalk. If you look at the last questions of this guy: http://stackoverflow.com/users/1906070/shiran?tab=questions <http://stackoverflow.com/users/1906070/shiran?tab=questions> you can see that they are about smalltalk/squeak and asked in last 2 days :). In fact I think that we should support asking questions on SO, as a lot of people are anxious to register and talk to others on mailing list, and prefer to search for solutions on SO. If weâll build reasonable amount of Q/A data, it can be easier for other people to start with Pharo. Cheers! Uko

I got the same problem and Cmd+ENter was already used on my machine set up. So it was not really simple.

Re: [Pharo-users] Roassal HTML exporter

by phil＠highoctane.be

Oooh! Very nice. I will try to integrate that into my software. A question: the color palettes are quite faded in Roassal examples (e.g. when I use the UML builder, some are light on light and hard to read). How hard is it to have a palette like this one for example: http://patterntap.com/pattern/color-palette-flat-ui-colors Congrats for the great job!

Roassal HTML exporter

by Alexandre Bergel

Hi! We have worked very hard on a Roassal exporter for the Web. Milton has produced the class RTHTML5Exporter, which may be simply invoked as: RTHTML5Exporter new export: aRoassalView. Check this out: https://dl.dropboxusercontent.com/u/31543901/RoassalHTML/index.html Try moving the mouse above the circle or dots in the curve. The html file you see from your web browser is the result of do-iting the following expression: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | c b c2 | c := RTComposer new. "======" b := RTGraphBuilder new. b view: c view. b edges connectFrom: #superclass; useInLayout. b edges if: [ :fromClass :toClass | toClass name beginsWith: 'TR' ]; connectTo: #dependentClasses; color: (Color blue alpha: 0.3). b nodes if: [ :cls | cls name beginsWith: 'RT' ]; color: Color blue. b nodes color: Color red. b layout cluster. b global normalizeSize: #numberOfMethods min: 5 max: 40 using: #sqrt; alphaColor: 0.4. b addAll: TRShape withAllSubclasses, RTShape withAllSubclasses. b build. c group.

Hans be polite. Else we will remove you from our list. What is Smalltalk V 2.0? if you want to have some support use our implementation.

Re: [Pharo-users] Extending GTSpotter

by Tudor Girba

Hi, I made a mistake and the post got reverted to a previous version that did not mention Cmd+Enter. The shortcut is present again in the post. But, the discoverability problem is still present and we need to fix it. It won't be a workspace, but likely a visual element or at least a menu entry. We are still working in this area.

A big +1 on Damienâs comment. Discoverability of useful things is too low. For example, I did not know about Shift-enter for searching until somebody showed it to me inadvertently when he was demoing something else :-/ That being said, I donât have a good solution to the problem either :-( Maybe have the standard image have a second workspace open that lists useful tools and their shortcuts? Plus put new tools and their shortcuts prominent in the release notes for each new release?
