Re: [Pharo-users] splitting a string using regex

by Steve Quezadas

I am answering my own question because I found the solution for it. This is the code that didn't work: > myString := 'one\n\ntwo\n\n'. > re := '\n\n' asRegex. > myString splitOn: re. The reason it didn't work was because you apparently have to escape the newlines pattern in the regex line. So the correct (working) example is here: > myString := 'one\n\ntwo\n\n'. > re := '\\n\\n' asRegex. > myString splitOn: re. I am putting this on here just in case someone else runs into the same problem. - Steve On 01/14/2019 09:06 AM, Steve Quezadas wrote: > I am trying to split a string in pharo using a regular expression. > > A simple example that works: > myString := 'one\n\ntwo\n\n'. > myString splitOn: '\n\n'. > > A simple example that does not work: > myString := 'one\n\ntwo\n\n'. > re := '\n\n' asRegex. > myString splitOn: re. > > The result of the above is I get the regular old string back > ('one\n\ntwo\n\n').

No diff from tonel repo

by Hilaire

Hi, When I look at the change between image and tonel repo on a changed package, the diff view is empty (screenshot). And the file is indeed unchanged: hilaire@PCHome:~/Travaux/Developpement/Bloc/GToolkitLinux64/drgeo/src/DrGeoII-UI$ cat DrGBlDrawable.class.st Class { Â Â Â #name : #DrGBlDrawable, Â Â Â #superclass : #BlElement, Â Â Â #instVars : [ Â Â Â Â Â Â 'balloonTarget', Â Â Â Â Â Â 'tipOn', Â Â Â Â Â Â 'selection', Â Â Â Â Â Â 'app', Â Â Â Â Â Â 'ox', Â Â Â Â Â Â 'oy', Â Â Â Â Â Â 'scale', Â Â Â Â Â Â 'underMouse', Â Â Â Â Â Â 'lastMoveEvent', Â Â Â Â Â Â 'valueItem', Â Â Â Â Â Â 'dottedLines', Â Â Â Â Â Â 'gridScale' Â Â Â ], Â Â Â #category : #'DrGeoII-UI-Widget' } Do I miss something?

splitting a string using regex

by Steve Quezadas

I am trying to split a string in pharo using a regular expression. A simple example that works: myString := 'one\n\ntwo\n\n'. myString splitOn: '\n\n'. A simple example that does not work: myString := 'one\n\ntwo\n\n'. re := '\n\n' asRegex. myString splitOn: re. The result of the above is I get the regular old string back ('one\n\ntwo\n\n'). I went through the source code and it should be able to handle a regex object: > "splitter - can be a subsequence, a Block or a Regex (String receiver > only). Any other object used as a splitter is treated as an Array > containing that object." I am baffled as to why it's not working. is there something simple I am missing? - Steve

IIUC a talent is behavior like a trait, but that can be dynamically added and removed from anObject instead of being permanently bound to the class ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo Weekly News formatting

by Benoit St-Jean

Would it be possible to "word wrap" posts on Pharo Weekly News. It's quite frustrating (and doesn't look good at all for newcomers) when you have to scroll right 10 miles away to be able to read a full sentence/paragraph. See screenshots attached. P.S. Tried with different browsers and the problem remains present. Thx ----------------- BenoÃ®t St-Jean Yahoo!

Re: [Pharo-users] adding instance variables (data) to the Object class

by Petr Fischer

It looks like I can't simply add statefull trait to the Object like this: ProtoObject subclass: #Object uses: TMyTrait instanceVariableNames: '' classVariableNames: 'DependentsFields' package: 'Kernel-Objects' After this, Pharo 7 VM goes to 100% of CPU usage, several GB of RAM usage and then crash. Or... what do you mean by "talents"? I found also this: https://github.com/tesonep/pharo-talents Thanks, pf > Talents with statefull traits will help you > > Ð¿Ñ, 7 ÑÐµÐ½Ñ. 2018 Ð³., 9:08 Marcus Denker <marcus.denker(a)inria.fr>: > > > > > > > On 6 Sep 2018, at 23:35, Petr Fischer via Pharo-users < > > pharo-users(a)lists.pharo.org> wrote: > > > > > > *From: *Petr Fischer <petr.fischer(a)me.com> > > *Subject: **adding instance variables (data) to the Object class* > > *Date: *6 September 2018 at 23:35:26 CEST > > *To: *pharo-users(a)lists.pharo.org > > > > > > Hello!

Hi, I would suggest re-downloading the image. Alternatively, you can reload the code in a fresh image: https://gtoolkit.com/#install Thanks for the feedback on the memory game. We will look at it.

Nowdays, how do you update your installed image to the latest GToolkit version? Btw, the Memory game build for Bloc has some issues with latest Bloc animation, and may be text, not sure. May be worth fixing. Thanks Hilaire Le 13/01/2019 Ã 15:55, Tudor Girba a Ã©critÂ : > Thanks for raising the issue. It was due to an incorrectly defined property.
