mentor wanted
by Roelof Wobben April 23, 2020

April 23, 2020

Hello, I like Pharo a lot but I hit a wall very often. With complex problems I do not see how to solve things in small steps. Is there somewhere who is willing to mentor me in how I can overcome that problem. Roelof

Missing Extract Method To Component refactoring
by Arturo Zambrano April 22, 2020

April 22, 2020

Hi everyone. Does anyone know what happened to the "Extract Method to Component" refactoring which is in Pharo 6, but seems to be missing in Pharo 7 and Pharo 8. I noticed there is a "Move method to another class", but it is quite different (in the sense that it does fewer checks and code editing during the refactoring). Maybe there is some project that needs to be loaded? Or it also may be the case it was not ported to Pharo7/8. In that case, maybe we can port it based on the original implementation from Pharo 6. Any information is welcome to avoid duplicated efforts. Thanks in advance. Arturo

All file accesses get externalCalledFailed exceptions.
by Michael Burns April 22, 2020

April 22, 2020

Newbie to Pharo Just installed the latest 8.0 stable image. Some things work, but anything I do to access any files gets an exception dealing with getcwd in libc.dylib. I am running MacOS Catalina. I searched and found the lib.dylib file and it is an alias to another .dylib file. Is there something else I need to install or configure? Sent from my iPad

Code Changes seems very slow in P8?
by Tim Mackinnon April 21, 2020

April 21, 2020

I havenât used P8 a lot, but I still find that the code changes tool still needs more work (I feel quite nervous about it vs. the now deprecated changes file). I noticed today on a new P8 image where I did a bit of work (not much). Having launched the image again today (and my laptop had accidentally rebooted), I opted not to load lost code (as I didnât think I had lost any) - but then I went to check what code it thought was lost and was surprised to find that on a new MacBook Pro - it takes 3-4 seconds (with no obvious wait cursor) to show 6700 events? Is this right? Obviously the UI needs improving to show some loading indicator, but why does it take such a long time to determine a smallish number of events? Or is 6700 a lot? Looking in detail it seems that the majority are due to project dependencies I loaded, but I worry that this doesnât scale very well? 100âs of thousands of events should take time, but sub 10k it seems like something odd is going on? Maybe it was always like this? Tim

Why are dropdown lists so chunky even in new Spec?
by Tim Mackinnon April 21, 2020

April 21, 2020

Great work on bringing spec to life, and it looks quite slick in the new PharoLaucnher - but I donât understand why in Pharo the dopdown lists (or ComboBox - name seems to vary) has always been so âchunkyâ and out of proportion? I was hoping that with Spec we would get something that looked more native and elegant but it seems like its not different? Why it this? With it being so thick - its hard to line up with other controls and it leaves lots of white space when collapsed and expanded? I find it makes the toolbar of the launcher look a bit silly against the icons. See the photos. And a comparison against a native combo box (from system preferences in OSX). See how the native one is so much thinner? Arenât we able to control this better?

Re: [Pharo-users] Embedding pharo in C++

Hi Roland, the function vm_main_with_parameters() starts the vm and it will not return until the image finishes. In my example, only when the SDL window is closed, the quit primitive is executed and the function ends. To do a nicer POC we need to make modifications in the image, so it handles keeping the image open.

[Pharo-dev] Label truncation in new Pharo 8.0 64-bit (stable)
by Shaping April 21, 2020

April 21, 2020

(Third try.) Can someone answer the questions below the screenshot showing the truncated labels? They are repeated here: 1) Can anyone suggest a fix (a code fix) for the truncated labels shown below in the screenshot of the Setting window? This happens in the Git client too? It happens when a fixed-width font is chosen as the default font. This is a design flaw in the GUIs. Cycling Settings (or any other Windows showing the same truncated-labels problem) isnât a fix, even if the window renders correctly the second time. The damaged area of the window is still not being invalidated correctly and then redrawn, or it is, and then is partially overdraw by the data fields to the right of the labels. Changing the font to any fixed-width font causes this problem, even without changing the default font size (10). You can see this by expanding all nodes in Settings, and paging down through them. The longest labels will be incompletely rendered. A possible solution is to use a 2-column layout, where the left column displays right-justified labels and the right one displays the matching left-justified data, checkbox, dropdown, etc. The left label-column could be auto-sized on opening after the longest labelâs size is determined. I mention this problem many months ago, in the midst of another failed port from VW, and presented the same screenshots. Stef made some comments about how this should not be happening, and seemed to be unhappy with the situation. I thought therefore that there would be some resolve to fix the issue broadly throughout the dev environ, but I donât know what came of that. I figured the fix was waiting for Spec2, which is now here. Is there a Spec2 expert here who can suggest how to use the new framework to fix the problem? 2) Will all Pharo tools be rewritten in Spec2, and does its formatting scheme solve the label-formatting problem, as font size is changed? 3) Why donât we opt for easy elastic/zoomable GUIs by implementing Pharo as a web app? Has this been discussed? Willow is looking very good. Is rendering speed still a problem for a complex web GUI served by localhost? For the localhost case, the speed difference seems to be approaching 0.

Rosetta Code
by Steffen MÃ¤rcker April 20, 2020

April 20, 2020

Hi, some of you might have hear of Rosetta Code, a Wiki that presents solutions to standard programming tasks in various languages. I figured that in many categories no Smalltalk/Pharo solutions are shown. Maybe we can contribute some pieces from time to time? I started with the following: https://rosettacode.org/wiki/Tree_traversal#Smalltalk Your comments are welcome. Best, Steffen
