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

by Alexandre Bergel

This is an exciting work Roland. Keep going! Bridging Pharo to other technologies is crucial, and you are doing well. Something you could do, is having Pharo running, on a different process, and exchanging (using a binary format) things between C++ and Pharo. We are doing this using CSharp and Python, and it works well. cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > On 21-04-2020, at 09:04, Roland PlÃ¼ss via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Roland PlÃ¼ss <roland(a)rptd.ch> > Subject: Re: [Pharo-users] Embedding pharo in C++ > Date: 21 April 2020, 09:04:56 GMT-4 > To: Pharo Mailing List <pharo-users(a)lists.pharo.org> > > > The dragon has been unleashed.

Re: [Pharo-users] All file accesses get externalCalledFailed exceptions.

H Michael- that seems strange, I just tried the following on a Pharo8 with Catalina: OSPlatform current currentWorkingDirectoryPath. > /Users/macta/Dev/Smalltalk/Pharo/Pharo 8.0 - 64bit Iâm using PharoLauncher, although my images are not stored in Documents, but ~/Dev/Smalltalk/Pharo (I adjusted the launcher settings). Not sure if that makes a difference? Or - perhaps you didnât allow Pharo disk read privileges (that is a new security check in Catalina - see the OSX System Preferences, Security and Privacy, Files and Folders.

All file accesses get externalCalledFailed exceptions.

by Michael Burns

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

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

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

by Roland PlÃ¼ss

The dragon has been unleashed. The game engine is now available to the public. See https://www.indiedb.com/engines/dragengine for more information. Right now the Smalltalk Script Module is a proof of concept with the GNU Smalltalk. The idea is to change this to use Pharo and bringing it up to the scope of the DragonScript module. The source code repository is at https://github.com/LordOfDragons/dragengine . I'll add a branch "feature-pharo" to contain all this work. Once Pharo is up to be used properly for embedding (or to help getting there) this branch can be used. Since it is right now in a proof-of-concept state I think it would be not a bad idea to experiment with Pharo embedding there when not yet too many engine relate complications are present. -- Yours sincerely PlÃ¼ss Roland Leader and Head Programmer - Game: Epsylon ( http://www.indiedb.com/games/epsylon ) - Game Engine: Drag[en]gine ( http://www.indiedb.com/engines/dragengine , http://dragengine.rptd.ch/wiki ) - As well as various Blender export scripts und game tools

[Pharo-dev] Label truncation in new Pharo 8.0 64-bit (stable)

by Shaping

(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.

> I think I found the reason - new meta-inf.ston files include absolute paths to image and VM, and those are different on my machines. I'm putting them on the same path. Unfortunately, having images on the same path doesn't help. It helps if you delete meta-inf file after copying. I opened the issue. Many thanks and best wishes, Tomaz
