X11 options on Ubuntu VM / Athens rendering problems
by J.F. Rick Nov. 18, 2017

Nov. 18, 2017

I'm running a fullscreen Pharo application on Ubuntu and I've noticed that Athens rendering gets way worse (maybe 10 updates per second) when I switch to fullscreen mode from inside Pharo. Ideally, I'd love for that to be fixed. In lieu of that, it would be cool if I could just maximize Pharo to the size of the screen to achieve good performance. Two things stop that: the Unity application bar and the title-bar. For the former, I can configure Unity to hide it. I noticed a '-notitle' X11 option when I execute pharo -help. I've tried using these X11 options and neither -notitle or -fullscreen seem to have any effect. Here's the command I run: ./bin/pharo --encoding utf8 -vm-display-X11 -fullscreen PATH_TO_IMAGE & Pharo starts fine but neither option seems to have any effect. I've also tried this in GNOME, thinking that Unity was the problem. Again, no effect. Any suggestions? Jeff

Teapot and Websockets
by Georges Nov. 18, 2017

Nov. 18, 2017

Hello, Is it somehow possible to have a Teapot server running within there a WebsocketHandler (for instance ZnWebSocketChatroomHandler). Something like: Teapot on WS: '/ws-chatroom' -> [: aWebSocket | self registerWebSocket: aWebSocket ]; start. Or is this totally wrong?

Exchanging information between 2 pharo applications (2 images running on two different computers)
by CÃ©drick BÃ©ler Nov. 16, 2017

Nov. 16, 2017

Hi all, I want to connect two applications (1 by image, each one on a different computer) so as as to exchange information (data) between them. So my question is about the best (smalltalk) practices to connect two app/image and exchange data. I imagine either with a direct connection through a network (TCP Socket, Web socket, pure HTTP with Zinc) and/or with a serial connection. At first, without any Â« security Â». But later, information exchanges will be encrypted. Iâve seen some information on how to use SerialPort, or even FileStream. I could do it (or at least simulate it with HTTP). What are the other options ? Socket ? Do we have P2P libs (I couldnât find) with eventually discovery features ? Any comment / suggestion / pointers are greatly welcome. TIA. CÃ©drick

[ann] pillar text editor
by Tudor Girba Nov. 15, 2017

Nov. 15, 2017

Hi, Pillar now ships with a text editor that also features a syntax highlighter. So, now, if you load the development version of Pillar: Gofer new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration; loadDevelopment. You will have an extra presentation when inspecting a .pillar file: The new thing here is that the highlighter is based on the Pillar PetitParser, and it is extensible for highlighting more parts if needed. The highlighting also can support actions. For example, the picture above shows the file to the right after clicking on the reference. Please take a look and let me know what you think. Cheers, Doru -- www.tudorgirba.com www.feenk.com "Things happen when they happen, not when you talk about them happening."

Hi, my team starts to use QCMagritte. For our needs we have imported SmalltalkHub repository to Github here: https://github.com/Afibre/QCMagritte I don't know if you (Diego, Stephan, Tobias) plan to use Github instead of SmalltalkHub. At least Github allows branches & pull request. Regards, Laurent Laffont

including Pillar in Pharo image by default
by Peter Uhnak Nov. 10, 2017

Nov. 10, 2017

Hi, I would like to propose including Pillar in the Pharo image by default. My reasoning: Since we are moving to git, and most people will use github, gitlab, and the likes, it is expected to include a README.md file (or possibly more extensive documentation) alongside the code. Which means that people will (and are) writing the README mostly by hand, which of course is problematic, as e.g. code snippets can get deprecated, screenshots become outdated, etc. As Pillar tries to address these problems, it would make sense to me to include Pillar in the image by default, as anyone using git (which eventually should be everyone) will most likely benefit from writing their documentation in Pillar. Similarly using Pillar would open an avenue to provide the documentation in-image, e.g. one exporter for html/markdown, and another one for Pharo's Help system. I could, of course, install Pillar every time, but considering thats extra effort and in the extra time I can fix the issues by hand, I don't have such an incentive to use Pillar for this. Questions & Problems: I don't know by how much would pillar increase the image size. Perhaps there could be (a) "lightweight Pillar" (that would include just pillar & markdown exporter), or (b) we would have different images for different uses. By different images I mean something along the lines of a) developer image - meant to be directly used by developers to create their software b) production image - as a foundation for running systems / users Does this make sense?

UFFI with asynchronous callbacks
by Jan Cada Nov. 8, 2017

Nov. 8, 2017

Hi, I would like to connect fingerprint reader to pharo - so far I am able to use C library to connect to it using UFFI, however the problem is that I can wait for fingerprint indefinitely ( blocking call to library) or register call-back for moment when fingerprint is available. The registration function returns immediately, so it is clear that the callback will be called from another thread. Is such situation supported by UFFI ? Thanks for any tip, Jan

Smalltalk Argument
by Paulo R. Dellani Nov. 8, 2017

Nov. 8, 2017

Dear all, after using Smalltalk for several years I developed a passion for the language (how not to?), and Pharo is just so great to develop with. So thank you guys for keeping this wonderful project running. Unfortunately, it is not easy to always point out why Smalltalk should be employed as "main development language" in a team or for a project. In the last discussion of this sort I was confronted with the question "where are we going to get new smalltalk developers if our startup grows or if you go?". Well, I had no good answer to that. What would have you answered? Cheers, Paulo
