In VA, tgey just introduced allSubStrings: for this matter, because subStrings was changed to return only non-empty parts... Do you find that in Pharo? Joachim "Esteban A.

Yes, thank you! And the story continues: with the PharoLauncher project [1] one is able to easily download a CI built image and run it locally.

Hi All, I encounter problems while installing magritte3 from the configurations browser. While loading, it removes #trimBoth #trimRight etc. messages from String. I wonder if anyone else is experiencing the problem. Thanks already, thushar

optimizing io
by Santiago Bragagnolo Nov. 20, 2013

Nov. 20, 2013

Hi all! Im making some performance enhancement on PhaROS, i realised that one of my common scenarios is having several sockets that should receive exactly the same information, in order to do that, im using n calls to the vm, which does n system-calls. I was wondering if there something done in: - send the same data to all the sockets in just one primitive - send the same data to all the sockets in just one syscall. I checked around in google but i didn't found anything useful, but probably i have no knowledge about the proper words for such search :). Thanks!

#subStrings: alternative preserving separators
by Esteban A. Maringolo Nov. 20, 2013

Nov. 20, 2013

I have a string like 'foo|bar||foobar|' and I want to split it into separate tokens like: 'foo|bar||foobar|' subStrings: $| -> #('foo' 'bar' '' 'foobar' ''). It is... to INCLUDE empty strings (or nil for that case) for the elements between to consecutive separators. I can't found a method implementing this in Pharo (in Dolphin it works as I expect). Thank you! Esteban A. Maringolo

Useful (hidden) features in Pharo 3.0
by Juraj Kubelka Nov. 19, 2013

Nov. 19, 2013

Hi, this week I have realized a lot of useful (hidden) features I did not know they exists. Those I have learned: Cmd+t â Nautilus, when method source code is displayed. It shows context menu related to the position of cursor. Cmd+Shift+p â Nautilus, in method source code, it extends selection according to AST Shift+Enter â Spotlight Do you know others? Thanks, Jura

Pyret: adding tests directly into classes
by Andy Burnett Nov. 18, 2013

Nov. 18, 2013

I have just come across the Pyret language. It looks interesting, but the part which particularly caught my interest was the way that they had built the unit tests directly into the classes, rather than having separate test classes. I think this is an interesting idea. It seems as though it would be easier to manage writing tests if everything were in one location. And this - might - mean that people were more likely to write tests. Has anyone else looked at this, and have an opinion on whether it would be a good addition to Pharo 4/5/X? Cheers Andy

CogVM arguments in Win32
by Torsten Bergmann Nov. 18, 2013

Hi Bernat, >how do I translate this into NB code Either invite Igor (author of NB) for lunch or try this: Its a C-structure, you convert it by wrapping this in a sublcass of "NBExternalStructure". See the examples already in a Pharo 3.0 image. Basically you need: - define a subclass NBExternalStructure subclass: #WinNotifyIconData ... - define the correct fields in a class side #fieldsDesc method according to the native data types used in the structure - call "WinNotifyIconData rebuildFieldAccessors" - setup the types in a shared pool that you can include later: - define the pool: SharedPool subclass: #WinTryIconConstants ... - in a class initialize method you can setup the type initialize NOTIFYICONDATA := #WinNotifyIconData. PNOTIFYICONDATA:= 'NOTIFYICONDATA *'. - by including the pool you can use "NOTIFYICONDATA" or "PNOTIFYICONDATA" in any native boost call. If you are in Pharo 3.0 load "OS-Windows" package from the config browser. Check the subclasses of NBExternalStructure there. I wrapped many other windows structures already so you can get an idea about it. For instance have a look at WinConsoleConstants>>initTypeConstants, there you will find the CONSOLE_CURSOR_INFO, CONSOLE_SCREEN_BUFFER_INFO structs wrapped in WinConsoleCursor, WinConsoleScreenBuffer classes. Compare them with the MSDN struct description. >Could the Windows API be any more convoluted and dev-unfriendly in any >possible sense? This question should go to M$ not Pharo-user ;) Bye T. BTW: I'm not sure "PNOTIFYICONDATA" alone will solve your problem if I remember correctly from my Smalltalk/MT and C/C++ times also playing with tray icons. I guess you need a callback that gets called when the icon is clicked or the tray icon menu is choosen (see uCallbackMessage member in the struct). You also need a handle to an icon - either the icon from the EXEs resource section or by loading one from a bitmap. That means wrapping the icon or bitmap apis too...
