Is there a way to load a dependent repository of assets that doesn't have a baseline - in my Metacello baseline?
by Tim Mackinnon Jan. 29, 2021

Hi - Iâm trying to create a baseline for my project so that it includes a dependent repository that has some assts but no code. Is there a way to do this in Metacello - I have a baseline dependencies like the following - and its the last line that fails as it not really a repo with a baseline in it - so Metacello signals an error - but Iâm wondering if there is something I can do to just load that repo without considering it as a baseline - Iâm after something like: spec resources: 'CP-ClientEnvironment' with: [ spec repository: 'github://ErikOnBike/CP-ClientEnvironment' ]. This is what I have to give an idea - possibly I could catch the exception and resume - or is there some cunning way (maybe even a post load script or something)? setUpDependencies: spec spec baseline: 'ZincHTTPComponents' with: [ spec repository: 'github://svenvc/zinc'; loads: #('Core' 'WebSocket') ]. spec baseline: 'CodeParadise' with: [ spec repository: 'github://ErikOnBike/CodeParadise/repository' ]. spec baseline: 'CP-ClientEnvironment' with: [ spec repository: 'github://ErikOnBike/CP-ClientEnvironment' ].

Why does Iceberg duplicate my Project when loading a baseline?
by Tim Mackinnon Jan. 28, 2021

Jan. 28, 2021

Hi guys - its been a while since Iâve had chance to code in Pharo - but I found a moment to pick up an old project - but when I load it into a fresh P8 image using a baseline - it seems to duplicate my project in iceberg? Whats up with that - is this a regression, or is it something abnormal about my project?

Each time that I download a fresh Pharo 9 image and open it this error message appears: "The current VM does not support TFFI Callbacks. It will use old implementations." I am using Windows 10 and have just updated the VMs using the Pharo launcher.

Project Ideas for Google Summer of Code 2021
by Oleksandr Zaitsev Jan. 27, 2021

Jan. 27, 2021

Hello, Google Summer of Code (GSoC) <https://summerofcode.withgoogle.com/> is happening again and this year there are some changes to the program organization. Most importantly: 1. GSoC this year will be two times shorter (175 working hours instead of 350 and 10 weeks of coding instead of full three months) 2. There will be 2 evaluations instead of 3 3. Student stipends are cut in half 4. Mentor stipends are reduced from $500 to $400 5. Students who are not enrolled in accredited programs can now apply, which means that there can be more applicants We are preparing an application from Pharo Consortium and we need your help with the list of project ideas. If you have a project that you would like to mentor or co-mentor, please add your idea to the list in the following template on github: https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics…, and send a pull request. Please check the guide <https://google.github.io/gsocguides/mentor/defining-a-project-ideas-list> to find the hints on how to propose a good GSoC project. For more information on what are the responsibilities of GSoC mentors, please consult the Mentor Guide <https://google.github.io/gsocguides/mentor/>. And if you have any questions, we are always happy to answer them. With all the best wishes, GSoC Program Organizers from Pharo Consortium Oleksandr Zaitsev <olk.zaytsev(a)gmail.com> Juan Pablo Sandoval <juampiboy(a)gmail.com> Serge Stinckwich <serge.stinckwich(a)gmail.com>

Pharo as a development environment for TiddlyWiki target/deployment platform
by Offray Vladimir Luna CÃ¡rdenas Jan. 27, 2021

Jan. 27, 2021

Hi, In a previous mail I told how our last semester explorations in the local communityÂ building, deploying and teaching Brea[1][2], a Pharo powered tool between a Static Site Generator and a headless CMS, led me towards TiddlyWiki[3] as the more dynamic counterpart of such deployments and today we a a little chat[4] with Norbert about trying to avoid the over complication of NodeJS and replacing that with a pretty simple Pharo based counterpart. [1] https://mutabit.com/repos.fossil/indieweb/ [2] https://code.tupale.co/Offray/Brea [3] https://tiddlywiki.com/ [4] https://twitter.com/NorbertHartl/status/1353319130804465668 I would like to start with something like tw5-server.rb [5], which is a pretty small Ruby script (46 lines) based in the Webrick and fileutils libraries, using the Pharo counterparts (Zinc? Teapot?). I don't have experience in Ruby, but maybe something in the list can help. It seems that the script opens a folder in the local file system and serves the files there. One of them is a TiddlyWiki file and once it is served (at port 8000) the class DefaultFileHandler (lines 18 to 35) takes care of saving the file and sucesive copies of it. Particularly lines 25 and 26 create a backup of the body in the current file and updates the Tiddly file body with new versions as saving is done in the web user interface. But further details scape me, particularly how the server knows that the TiddlyWiki file is being save. [5] https://gist.github.com/jimfoltz/ee791c1bdd30ce137bc23cce826096da Any corrections on my understanding so far, hints or pointers on how to get something similar with Pharo would be greatly appreciated. Cheers, Offray

Headless VM crashing on viewing class side methods
by kmo Jan. 27, 2021

Jan. 27, 2021

I get an illegal instruction VM crash when trying to use the latest headless VM to view class side methods. I download the image and VM like this - curl https://get.pharo.org/64/90+vmHeadlessLatest | bash I open the image with ./pharo-ui Pharo.image I open a system browser and pick a class I click to view class side methods and crash! I'm using Xubuntu 20.04. I've tried this on two computers both running Xubuntu 20.04. Same thing. It's perhaps no coincidence that I also get an illegal instruction crash if I try to load the pharo GTK bindings. Does this mean that the headless VM has a serious problem with some chip sets? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Request for a #Magritte channel in Discord Pharo server
by Sanjay Minni Jan. 27, 2021

Jan. 27, 2021

Do you think we could have a #Magritte channel in Discord Pharo Server I am working on it for my application and getting stuck and want to avoid flooding messages here. It could mean make or break in adapting Magritte. Magritte ML itself is inactive ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
