Re: [Pharo-users] [ANN] Pharo Launcher 2.0 released!

by TomaÅ¾ Turk

Hi Christophe, > If it worked with previous version, there is no reason it should not work with the current Pharo Launcher version. I think I found the reason - new meta-inf.ston files include absolute paths to image and VM, and those are different on my machines. I'm putting them on the same path. Thanks and best wishes, Tomaz

Re: [Pharo-users] [Pharo-dev] FW: Label truncation in new Pharo 8.0 64-bit (stable)

by Pavel Krivanek

Hi, you should never change the size of fonts only because it does not change the display scale factor. Try to first click on one button of predefined styles (small, medium...) and then change the font face without significant change in the font size. -- Pavel ne 19. 4. 2020 v 16:57 odesÃlatel <shaping(a)uurda.org> napsal: > Below you can see a section of Settings where the labels do not fit.

Re: [Pharo-users] Non-blocking IO

by tbrunz

I think you can do what you describe if you use #fork to create separate processes for each of your concurrent HTTP calls. Here's an example -- Try the following (from http://forum.world.st/Teaching-fork-td4786444.html) 10 timesRepeat: [ (Delay forSeconds: 1) wait. Transcript show: 'hello'; cr ]. Then the following : [ 10 timesRepeat: [ (Delay forSeconds: 1) wait. Transcript show: 'hello'; cr ]] fork. You can also spawn OS sub-processes: https://github.com/pharo-contributions/OSSubprocess -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Congratulations on the new launcher! The experience is far better than with the previous version, nice work! I noticed something peculiar - I have two computers and am syncing the folders structure between them. If I create a new Pharo 8.0 image, work on it on this machine and finish, then it gets copied to the second machine. PharoLouncher on this second machine sees the image, however nothing happens if I lounch it. This happens also vice-versa with a new image on the second machine and its copy on the first. Both machines share the locations of - template source files - image inicialization scripts - images - VMs This happens on Windows 10. This kind of setup worked with previous version of launcher.

Non-blocking IO

by dturczanski

Hi guys, I'm wondering whether Pharo support any form of non-blocking IO. You can find such IO support in Node.js or Java NIO packages and on Linux they use select/poll async IO system calls. An example scenario is to be able to schedule 10 concurrent HTTP calls taking 1-5s and wait for them to finish. Naturally, if you perform the calls sequentially you'll wait for much longer than if you fire the calls concurrently. Is it possible in Pharo? I've only spent a few hours reading about the platform but I'm still not sure whether the built-in process/threading supports such scenario. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
