Hi to all I want to use the next instruction in my code response := ZnEasy get: 'https://archive.softwareheritage.org/api/1/ origin/git/url/https://github.com/hylang/hy'. response. The previous code works from command line or in a webbrowser, but I does not work with ZnEasy Because it takes the previous link as: a ZnRequest(GET /api/1/origin/git/url/https:/github.com/hylang/hy) Could you please tell me what can I do for this situation?

Pharo 7 provisional HOWTO
by Pavel Krivanek Aug. 24, 2017

Aug. 24, 2017

Hi, this mail describes how to start to send pull requests to Pharo 7 Github repository from Pharo 7. Preparations ===================== - you need to have a Github account and set SSH keys. See https://help.github.com/articles/connecting-to-github-with-ssh/ - create own pharo-project/pharo repository fork. Go to https://github.com/pharo-project/pharo, click on "Fork" button and follow the instructions Get Pharo 7 image ===================== The CI jobs for the Pharo 7 defelopment are currently not fully set and we still do not publish Pharo 7 image to files.pharo.org so you cannot get it using zero-conf scripts. But we have a provisional CI job that bootstraps the Pharo 7 image. https://ci.inria.fr/pharo/view/7.0/job/70-Bootstrap-32bit/ There download a file named like Pharo7.0-32bit-hash.zip and decompress it. Unlike Pharo 6 images, the archive contains three files. Image, changes and sources. In Pharo 7 you have the sources file for every bootstrapped version. It has a commit hash in the name and it cannot be shared between different Pharo 7 imges, however it can be shared between images that were created as snapshots with the same bootstrapped image as ancestor. Create local clone ===================== You need a local clone of the Pharo repository. Because it contains a lot of small files, it is not a good idea to have own clone for every image. You can have only one and share them between images. But because of some current Monticello constraints you need to have the clone placed in the image directory in a folder with name 'pharo-core'. In this step we will clone the Pharo repository from pharo-project/pharo Github repository and add your fork as default pull target. We will update your fork repository to contain all latest commits from the Pharo repository in the branch named 'development'. For latest stable version (Pharo 6) we use the master branch. In the end we will checkout the repository to a particular commit from which the downloaded Pharo 7 image was bootstrapped. Imagine that you have a Pharo 7 image that is several days old and the development branch has already some commits that change code. If you would take this older image, checkout to the development branch and then do your commit, your would revert all changes done in not-loaded commits. The other option is to update your image to correspond to the repository latest commit which requires packages reloading. If you checkout to a particular commit, you are in detached HEAD state. In this state you cannot do commits directly. You need to firstly create new a new branch which we will do anyway. Evaluate the following code. This functionality will be later direct part of Iceberg UI. Do not forget to change the user name. username := 'YOUR-USER-NAME'. repository := IceRepositoryCreator new url: 'git@github.com:pharo-project/pharo.git'; location: ('pharo-core' asFileReference ensureCreateDirectory); subdirectory:'src'; createRepository. repository checkoutBranch: 'development'. repository register. fork := (IceRemote name: 'myFork' url: ('git@github.com:{1}/pharo.git' format: {username})). repository addRemote: fork. repository pushRemote: fork. repository pullRemote: repository origin. "update fork" repository backend pullFrom: repository origin. "use this low-level form to prevent packages reloading" repository push. "checkout to the commit from which the image was bootstrapped" repository checkoutBranch: (SystemVersion current commitHash). Use already created clone ===================== This is alternative to the previous step. Let's suppose that you already have your local clone. You take some Pharo 7 image and you want to create commits. Then you need to create a symlink or move/copy the repository into your image directory. Remember, it must be named pharo-core (we do not use the name 'pharo' to avoid collision with VM executable). In this step we will register an existing Pharo repository clone, set your fork as the push target, update your fork and then switch to the particular commit. repository := IceRepositoryCreator new location: ('pharo-core' asFileReference); subdirectory:'src'; createRepository. repository register. fork := repository remotes detect: [ :remote | remote remoteName = #myFork ]. repository pushRemote: fork. repository pullRemote: repository origin. repository checkoutBranch: 'development'. repository backend pullFrom: repository origin. repository push. repository checkoutBranch: (SystemVersion current commitHash). Issue processing ===================== - create new case on FogBugz to get the issue number - open Iceberg and from the context menu on the 'pharo' repository do: Pharo - Create new branch from FogBugz issue, enter the issue ID and it will fill the full branch name for you - create your changes (you can do it before the creation of the branch too) - commit and push your changes in Iceberg, this way you will commit your branch to your fork repository. Remember that the Iceberg commit window has two buttons, one for local commit, the second for commit with immediate push. They can be very long because they contain the full branch (issue) name - in Iceberg in the 'pharo' repository context menu do: Pharo - Create pull request, fill your - fill your Github credentials - leave the PR title, comment is not required, check the pull request head and base. The base MUST be pharo-project/pharo development. Create the pull requests - go to https://github.com/pharo-project/pharo/pulls, check your pull requests and put URL of it into the issue record on FogBugz (as a comment). Resolve the issue as Fix review needed Cheers, -- Pavel

Aug. 24, 2017

Hi Esteban, It looks like there has been some recent activity with VM plugins, I would really appreciate it if you could also add #20294. This is the plugin that fixes #isSymlink and adds symlink attributes. See: https://pharo.fogbugz.com/f/cases/20294/Add-FileAttributesPlugin-to-the-lin… If there's anything I can do to help the process, please let me know. Thanks, Alistair

TechTalk Dates for the rest of 2017
by Marcus Denker Aug. 24, 2017

Aug. 24, 2017

Hi, We have added dates for tech talk discussions / Demos for the rest of 2017: https://association.pharo.org/events <https://association.pharo.org/events> We need to find some topics. In the past we had often formal âtalksâ or demos about a topic with discussion afterwards, but a more relaxed form of just an open discussion about a topic is possible, too, If you like to lead one of the dates (all but the November dates are available still), this would be great. If a date does find a topic, we keep it as an open discussion round. Marcus

[Ann] PharmIDE is renamed to TelePharo and moved to github
by Denis Kudriashov Aug. 24, 2017

Aug. 24, 2017

Hi. In the team we finally agreed on the end name for project. It is now TelePharo. Prefix "tele" means some action on or by distance. And this is what the project is about: to work remotely with Pharo images. Not all people like this name. But there are no name which was good for everybody. So it was decision. And we now continue with it. With new name project was moved to github repository https://github.com/dionisiydk/TelePharo with all dependencies. Feel free to fork and report bugs. You can find more details in my blog http://dionisiydk.blogspot.fr/2017/08/pharmide-is-renamed-to-telepharo-and.… . Best regards, Denis

[Ann] Workflow
by Max Leske Aug. 23, 2017

Aug. 23, 2017

Hi everyone, Stef has asked me whether Netstyle would release our workflow engine to the public, so here goes: Workflow (originally called "Aare") was conceived as part of an application that Netstyle developed back in the day. We can't release all of that code but we can release the engine. I've published it on Github with an MIT license (loadable via baseline): https://github.com/Netstyle/Workflow. Please note: - Workflow used to depend on OmniBase for storing objects (one of the main superclasses inherited from an OmniBase class for that). I've removed that dependency. - As this only includes the engine, there's no UI and the things shown in the whitepaper (see repository) are technically correct but are missing the appropriate model (the UI was written with Magritte and Morphic). - The code is from 2005 and we haven't touched it since then, so there might be a couple of hiccups. - We can't provide full support for the code but I'll be happy to talk to anyone interested in maintaining or improving it. We at Netstyle hope that Workflow may be useful to some of you. Cheers, Max

Latest Debian, Ubuntu and CentOS packages of the pharo-vm
by Holger Freyther Aug. 23, 2017

Aug. 23, 2017

Hi, when running Pharo in production you might want to install the image and a VM from distribution packages. So far there were no current public packages and during the last months I have modernized the debian packaging and recently added CentOS rpm packaging as well. The process of generating new source packages is integrated into the pharo-vm travis-ci build as well. Every time that master of pharo-vm.git is updated a new source package will be uploaded to the Open(SUSE) Build Service and new packages will be built and are available in a "latest" package feed. The generated (and used) sourcecode is inside the source package and will be archived by the OBS platform (one can even nicely diff versions). The "stable" VM is not built from pharo-vm.git (yet?) so it doesn't show on OBS yet. Below are some semi-tested installation notes in case you want to try it out. The binary names are picked to allow to install the 32bit and 64bit VM in parallel. The names currently are: - pharo6-32 (32bit version) - pharo6-64 (64bit version) - pharo6-32-ui (32bit version with X11 dependencies) - pharo6-64-ui (64bit version with X11 dependencies) CentOS 6.8: # Add the repo $ yum-config-manager --add-repo http://download.opensuse.org/repositories/devel:/languages:/pharo:/latest/C… # Install 32bit packages (with X11 dependency for *-ui or not) $ yum install pharo6-32-ui.i686 or pharo6-32.i386 # Install 64bit packages $ yum install pharo6-64-ui.x86_64 pharo6-64.x86_64 CentOS 7 (only 64bit): $ yum-config-manager --add-repo http://download.opensuse.org/repositories/devel:/languages:/pharo:/latest/C… $ yum install pharo6-64-ui.x86_64 pharo6-64.x86_64 Debian 8: # Add signing key $ wget -O - http://download.opensuse.org/repositories/devel:/languages:/pharo:/latest/D… | apt-key add - # Update and install $ apt update $ apt install pharo6-32-ui pharo6-64-ui (or pharo6-32 or pharo6-64) Ubuntu 14.04 LTS # Add signing key $ wget -O - http://download.opensuse.org/repositories/devel:/languages:/pharo:/latest/x… | apt-key add - # Update and install $ apt update $ apt install pharo6-32-ui pharo6-64-ui Ubuntu 16.04 # Add signing key $ wget -O - http://download.opensuse.org/repositories/devel:/languages:/pharo:/latest/x… | apt-key add - # Update and install $ apt update $ apt install pharo6-32-ui pharo6-64-ui
