Re: [Pharo-users] Roasssal not working on Windows with Pharo 6.1

by kmo

Many thanks. I tried this and it worked fine and Roassal installs and runs. I then typed the same gofer command into my original Pharo 6.1 directory and I got an error - #withSqueakLineEndings was sent to nil. Perhaps that's a clue to what was going wrong. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

You are collecting data from web pages, so you have no influence on what you'll get as input. I don't think this should be solved in #isSeparator. Stephan

In method editor status bar there is explicit checkbox "extension" to specify external package for the method. We should move away from star convention and work directly with packages. Calypso gives you the tools for this. But I will add special notification when user creates new protocol with star.

Is a non-break space whitespace?

by PBKResearch

Hello All I have a little puzzle to disturb your Sunday lunch, maybe. I have been scraping text data from web pages, which often comes with redundant space before or after. I routinely use 'trim' on the final string output, but I have found cases where there are still redundant spaces. Inspecting the results, I find that the characters are non-break spaces (codepoint 160, Unicode U+00A0). Looking at the code, String>>#trim depends on Character>>#isSeparator, which does not answer true for a non-break space. I can use trimBoth: [:char| char asInteger = 160] to remove the redundant spaces if I know where to expect them, so it is not a major problem. But the question remains: should non-break space be included in the list of separators in Character>>#isSeparator. Peter Kenny

Re: [Pharo-users] X11 options on Ubuntu VM / Athens rendering problems

by ClÃ©ment Bera

Hi, I describe in the next paragraphs what I do to build application with Pharo at 50 fps. Now I am using a SDL2 window with OSWindow and not the default Pharo window for rendering. There is a fullscreen option with OSWindow, I don't use it but I've just tried it works fine. To use Athens/Cairo I start the VM headless and I open from the code a window using the SDL2 binding (OSWindow), then I extract the window surface as a cairo surface to draw on it using Athens and I use SDL2 to manage events (mouse, keyboard). That way I don't even start morphic/WorldMorph which wastes cpu ressources. I built this video game that way: https://clementbera.wordpress.com/2016/08/29/sdl2-cairo-headless-for-realti… https://www.youtube.com/watch?v=srPdFgbyS6s The game is running in Pharo 4 (pre-Spur). I configured it to run at 50 fps but from time to time some frames are dropped for performance so I would say it is running at around 48-49 fps in practice. I think it should work on the latest Pharo but you need to ask on pharo-dev how to use OSWindow. Some APIs have changed since Pharo 4. Since the latest Pharo version is now using Spur I expect the performance to be way better and I think 50 fps is definitely manageable on a laptop. Note that this is still Pharo so if you want something which looks real-time you need to be careful about you object allocation rate in-between frame rendering. I hope this can help.

Hi Juraj, This would be a simpler form of the type/class tags that are often used in JSON encoding. Since there are many ways to do this, there cannot be one solution. NeoJSON mapping was not designed to cover these cases. Nor is JSON meant to do this. STON is one (rather elegant if I may say so) answer to this problem.
