#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

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...

Esteban said <<< Hi, It does not really matters where you put the test. What matters is to have the tools that show them properly, and we are going in that direction. We already have ways to "jump to tests" in Nautilus, and we will continue improving that to show them together (for example). But I do not think the tests need to be *in* the class definition to have same level of interoperation. Esteban >>> I agree. The actual architecture doesn't matter. The critical factor is making it as easy as possible to write/navigate tests. I didn't know about the Nautilus features. I shall have to go and experiment. Also, thinking about Doru's point. I wonder if we could write tests/examples in the comments section of code. It might be an interesting addition

Help in St. Petersburg?

I am sorry for the off-topic. A friend of mine was stolen in Sofia and now she is completely out of money going to St. Petersburg in a few days. Anyone there who can help her a little bit would be really appreciated. Cheers, HernÃ¡n

Doru said: <<< I stumbled across this idea when Markus Gaelli chose it as a PhD topic about ten years ago (man, I'm old). The main idea was not to provide tests, but examples that happened to have assertions. The goal was twofold: (1) provide live documentation with real objects, (2) provide another way of composing tests. The project did not really come to fruition, but I still think this is highly interesting topic. Part of the ideas were later implemented in Phexample (http://www.smalltalkhub.com/#!/~Phexample/Phexample/) and JExample (http://scg.unibe.ch/research/jexample) >>> That's really interesting. I had never heard of Phexample - so many interesting projects, so little time! - I like the approach of building on tests. Do you know if this will work in Pharo 3? Also, I may have misunderstood what Pyret was doing. Perhaps it is more about examples.

Here is a demo of the i18n support in QCMagritte. It supports live editing of the languages and strings used in your application. youtu.be/cTut44Xs3_U Stephan

In the multi language demo of QCMagritte, a magritte visitor is used that changes all label:, checkboxLabel:, comment: and group: sends in descriptions to automatically use a multilanguagestring. The parameter is used as the key. All unique keys are collected. The default translation is the key. That is used for missing translations. Languages can be added on the fly. The demo has a simple UI to directly add and change translations. The whole translation table can be written to csv, and read back. This is not shown in the video Stephan Verstuurd vanaf mijn iPhone
