How to get text field value and send to bat file
by shawon58 July 25, 2020

July 25, 2020

Hello i am new in GUI in pharo . I am following Spec2 form where i can able to make form that send value and show in result tab. But my concern is i want to send the text field value to a Bat file which will execute a C++ file. So i want to use LibC system: 'a.bat textfieldinput' like this but how to do i dont know. If anyone have idea pleas share with me. In the screenshot u can see that i can send a number that shows in result tab. But now i want to send same number when i press submit than it will send to LibC system: 'a.bat textfieldinput' means in bat it will receive the number from the form. Thanks <http://forum.world.st/file/t372453/form.png> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Bit Manipulation Challenge
by Sean P. DeNigris July 23, 2020

July 23, 2020

I want to take an IP address routing prefix in CIDR [1] notation (i.e. the 24 in "192.168.100.14/24") and convert it into subnet form (i.e. 255.255.255.0). I came up with 4 ways to do that (see below), but none stand out as best (although #3 and #4 seem a bit more straightforward as they avoid the `max` temp). How would you go about it? Here are the ways I came up with: cidr := 24. shift := 32 - cidr. max := #[ 255 255 255 255 ] asInteger. "1." ((max bitShift: shift negated) bitShift: shift) asByteArray. "2." (max bitClear: (2 raisedTo: shift) - 1) asByteArray. "3." ((2 raisedTo: shift) - 1) bitInvert32 asByteArray. "4." (((2 raisedTo: cidr) - 1) bitShift: shift) asByteArray 1. https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

[ANN] Pharo Launcher 2.0 released!
by Christophe Demarey July 20, 2020

July 20, 2020

Hi all, Pharo Launcher 2.0 has just been released! It is available from http://pharo.org/download <http://pharo.org/download>. This new version introduces major changes: The UI has been fully rewritten using the new Spec2 framework <https://github.com/pharo-spec/Spec> and the Commander2 library <https://github.com/pharo-spec/Commander2>. UI has been revamped to increase usability, especially for newcomers. The main window is now composed of a toolbar and the list of images. The template list is now available when clicking on the new image button. Documentation web site : All Pharo Launcher features are now explained in the new documentation available at https://pharo-project.github.io/pharo-launcher. You can contribute easily by clicking the *edit on GitHub* button. You can now have many launch configurations for an image (VM to use, vm and image arguments). It means you can use headless Pharo VM from Pharo Launcher. When creating a new image, you can specify an initialisation script that will be run once at the first image launch. It is useful to load your project code in a stock Pharo image for example. See https://pharo-project.github.io/pharo-launcher/create-images/#image-initial… You can now define your own template sources in addition to official sources (see https://pharo-project.github.io/pharo-launcher/templates/#create-your-own-l…) including authenticated sources. Improved image metadata. Pharo Launcher now manages all image metadata in a single STON file (including description, Pharo version). Big thanks to all contributors, including issue reports. It is also the opportunity to thanks Damien Cassou, the original author of Pharo Launcher. Here is the changelog: Pharo Launcher v2.0 <https://github.com/pharo-project/pharo-launcher/releases/tag/2.0> The list of closed issue is too long (68) to be listed but you can browse it here: https://github.com/pharo-project/pharo-launcher/issues?q=is%3Aissue+is%3Acl… Here are some highlights: New features: Documentation web site Image initialisation script Launch configurations, headless VM support User template file in addition to the official template file Jenkins server template now support pipeline projects Support of private Jenkins server Support of authenticated HTTP server Improvements: Monitoring of image launch failures to give back the error message (if any) Newly created image is automatically selected in the image list Allow to set image description at creation time Better error management (you will have the choice to ignore them or debug them) Add a poor version column in image list Speedup (especially when image repository has a lot of images) Bug fixes: Fix use of system unzip on Windows Regards, The Pharo team.

Iceberg: Installing a baseline from a self hosted Git/Gitea repository branch
by Offray Vladimir Luna CÃ¡rdenas July 19, 2020

July 19, 2020

HI. I'm migrating my packages from StHub to a self hosted Gitea instance. I have already a test |BaselineOf| hosted there and referring to other self hosted repositories. I'm following the [Baselines documentation](https://github.com/pharo-open-documentation/pharo-wiki/blob/… for all this. But when I try to load the baseline from the |beta/migration| branch running the code below, I get the message |Could not resolve: BaselineOfGrafoscopio in https://code.tupale.co/Offray/Grafoscopio/src/branch/beta/migration/|. How can I load Baselines hosted in a branch inside a self hosted Git/Gitea repository? |Metacello new baseline: 'Grafoscopio'; repository: 'https://code.tupale.co/Offray/Grafoscopio/src/branch/beta/migration/'; load | |Thanks,| || |Offray| ||

UK Smalltalk User Group Meeting - Wednesday, July 29th
by Giovanni Corriga July 19, 2020

July 19, 2020

The next meeting of the UK Smalltalk User Group will be on Wednesday, July 29th. Peter Svensson will present his work on Cloudsdk-st. Cloudsdk-st (https://github.com/psvensson/cloudsdk-st) is an experiment in ways to work with cloud deployment from a Smalltalk image. Traditionally cloud deployments run 'out of band' in separate build scripts or build/CI/CD systems. This project lets you define Docker images (using Dockerfiles) for Smalltalk, send them to the build system of a cloud provider directly and then choose what kind of service you want your image to be (cloud function or long-running VM). Currently it only supports Google Cloud and has a very rough UI. Future plans include support for AWS and Azure as well as better feedback and a Spec2 UI. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page https://www.meetup.com/UKSTUG/events/cbklbrybckbdc/ to receive the meeting details. See you there!
