Can you make a search for your PharoDebug.log, because I can see, at least on P7 and Linux, this file is not always located nearby the image but at the user root directory.

Pharo Launcher

Playground and Smalltalk script

by Hilaire

Hi, Same question asked there http://forum.world.st/Pharo-4-Playground-open-file-menu-tt4823334.html. I tried to follow the suggested solutions: 1) Following article: http://www.humane-assessment.com/blog/managing-external-pharo-scripts-with-… Accessing to DrGeo SmalltalkScripts folder from Spotter, it works when the user input ../../SmalltalkScripts. As it is not a discoverable features for the user, I want to add a menu entry in the world menu to open Spotter with path ../../SmalltalkScripts already set. I tried: Â GTSpotterMorph new Â Â Â Â Â Â extent: 400@500; Â Â Â Â Â Â doLayout; Â Â Â Â Â Â spotterModel: (GTSpotter on:DrGDefault mySketchesPath parent / 'SmalltalkSketches' ); Â Â Â Â Â Â openCenteredInWorld (Btw, the descriptions in the Settings browser concerning Spotter are still broken.) When dive-in the display script is empty, any idea? I have to Enter to get it seens in an inspector. Moreoever I see one minor issue: Spotter looks at relative path relatively from the folder where the image was built not from where it is runned. Note: FileBrowser properly open relatively to the path where it is runned. 2) I tried the complementary approach with play-cache, I edited in the setting browser the play cache path to DrGeo SmalltalkScripts. Now when I edit some new scripts in the Playground, I can rename it and it is saved in the SmalltalkScripts. Now when exploring, the SmalltalkScripts, there are several additionnal file not meaning full for the enduser. Is there a way for Playground to only save one file as pageName.st? An interesting option will be for me to add two menu entries in GTPlayground to load/save script. Is it possible? It will make the user experience a bit easier. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] [SmalltalkCI] loading tonel dependencies?

Bernardo, I've proposed a pull request to fix this problem ( https://github.com/hpi-swa/smalltalkCI/pull/367) and tested it against a fork of your repo ( https://travis-ci.org/gcotelli/earley-parser/builds/366766621 ).

Re: [Pharo-users] Where do we go now ?

by Stephane Ducasse

Ben can you open a bug entry. Now I can tell you that the launcher is one of the most complex application built in Pharo because it has to adapt to multiple OS, multiple version of OS, multiple versions of the images and the VM. For example we discover that we cannot open certain pharo 30 image with the pharo 30 vm but better with a pharo 40 vm.
