An image is like a computer game that can save its state to disk. The VM is for running the game. With a fresh image, you start the game with a clean slate. With a saved image, you restart the game where you last left it. And programming in Pharo is usually as enjoyable as playing a computer game. :-) Pierce

Re: [Pharo-users] Move image

Hi Robert, The "#selectedLaunchConfiguration was sent to nil" sounds like an error in Pharo Launcher version 2.0 that several people have seen. It's corrected by updating Pharo Launcher to version 2.2. You can get it at https://pharo.org/ ; it's not necessary to uninstall 2.0 first, just install 2.2. -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

OK, "solved" then next step. When I have started a Image (from a VM) I can save that Image via "Pharo|Sace As" anywhere I want. Then I quit the image. Afterwards I switch back to the Launcher to "Launch Image From Filesystem". However I am greeted with the following error message "#selectedLaunchConfiguration was sent to nil" Can anybody help? Thx Ciao robertj

Hi, I found the settings on how to change the file system folder. Kind of. In the settings browser|Pharo Launcher I can change the location. However now ALL of my images are put into that specific folder. However I want to push ONE specific image into ONE specific folder. How do I do this? Thx Ciao robertj Von: robert(a)robkuz.com <robert(a)robkuz.com> Gesendet: Sonntag, 16. August 2020 17:43 An: Pharo-users(a)lists.pharo.org Betreff: Move image Hi, when I create a new image using the launcher then the image will be created at the following location (C:\Users\robert\Documents\Pharo\images\Pharo 8.0 - 64bit (stable)). Is there a way to define a different location when creating an image (or afterwards)? Best regards Robert

Re: [Pharo-users] GTK3 / PDF Viewer

by tesonep＠gmail.com

Hello, Robert I have checked previously and seems that there is not a component to present PDF in Gtk basic library. Gtk components are intended to be building blocks to other more complex UI. For doing what you are intending maybe it is required to build a more complex window using Gtk components. One alternative is to do a binding with the Ghostscript library (https://www.ghostscript.com/doc/current/Lib.htm) that already provides all the support to render PDFs. It is designed to call the interested user with a callback with instructions how to render the content. This rendering can be later done directly in Morphic or in Athens. In both cases, they can be shown as part of a GTK window. Another alternative is to check the implementation of Evince (the GTK based PDF presenter of Gnome) to check if it provides a component that can be extracted. It was supposed to be a reusable component but there is lack of documentation of it (https://developer.gnome.org/libevview/stable/) Cheer, Pablo On Sun, Aug 16, 2020 at 5:48 PM <robert(a)robkuz.com> wrote: > > Hi, > > > > what is the best way to integrate a PDF Viewer with a Spec2 / GTK3 application on Windows? > > I couldnât find any mentioning of PDF viewer on the GTK3 site. > > > > Thx for your help > > > > Best > > > > Robert -- Pablo Tesone. tesonep(a)gmail.com

Re: [Pharo-users] [ANN] Smalltalk's Successor

by tbrunz

Hi Richard, I had the same impression, that "Pharo is Smalltalk's successor". (Without any negative feelings toward VAST and VW; they fill a very important role for commercial use -- businesses depend on the kind of support that a commercial distribution provides and are very willing to fund that.) The future of Smalltalk is being created every day with commits to the Pharo Project. Who's to say a company can't be created to provide commercial support for Pharo in the way that Red Hat does for Linux? And the Pharo Consortium is, in many ways, already one such entity. So please do contribute to making the booklets better, Richard! I started last fall (and need to start up again) and found it very fulfilling, as well as educational. It's easy to do; for you & others, here are the basic steps: 1. Fork a booklet repository and then clone it. 2. Set a git 'upstream' to the original (because you'll be trading revisions as you go). 3. Edit the Pillar markdown, add new material, etc. 4. Push and submit a Pull Request. 5. Continue working (i.e., start a 'pipeline' of edit submissions). 6. Note that you can modify the target of a PR while the PR is still "in review". 6. Check the WIP 'releases' that the CI system generates to proofread. I was using Atom and it's markdown rendering, which is imperfect, but it was sufficient. Sean DeNigris recently suggest editing in Gtoolkit's live Pillar editor: "It's beta, but a compelling experience. I did a little screencast here: https://youtu.be/GZOYF82h9qA". I'm looking at it this week for my own use. There's also the 'Documentation' channel on the Pharo Discord site. I'd like to see the 'doc writers' start to interact there (and here); the last Discord entry was 6 weeks ago... -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
