Answer whether anObject is found." [self atEnd] whileFalse: [self next = anObject ifTrue: [^true]]. ^false first btw, did you debug into this method to understand why it doesn't work with strings? It would help observation to change the method line this... whileFalse: [(x:=self next) = anObject ifTrue: [^true]]. I don't see anything useful in the superclass, but I see PositionableStream>>positionOfSubCollection: Short answer is that you skipTo: wont work with strings since the stream elements are not Strings, they are Characters. You will need to create your own method for this, perhaps named skipToSubCollection: cheers -ben

Skipping to a substring in a stream

by Leonardo Silva

Hi, I'd like to skip to a specific position in a stream based on a substring. I got the following example that works for a single character: stream := 'abcdef' readStream. stream skipTo: $e. stream next. -â $f But it does not work for substrings. I'd like to have something like: stream := 'abcdef' readStream. stream skipTo: 'de'. stream next. -â "But this returns nil" Do you know how to do it? Thanks, Leonardo

Re: [Pharo-users] Google Summer of Code 2016

by Jigyasa Grover

Hey Serge :) As a former Google Summer of Code student, I believe the participation of Pharo as an organization in GSoC program shall enlighten the masses about this powerful yet not widely known environment. Good luck ! Let me know in case of any help required. Would be happy to contribute.

by Jigyasa Grover

Hello Pharo-ers I am excited that my talk proposal on "My journey in FOSS with Pharo and Fossasia" has been accepted for FOSSASIA Summit 2016 being held on March 18-20 in Singapore this year. Hi eMBee :) It'll be great to have a Pharo/Smalltalk booth at the conference venue with a nice poster/banner. Let me know in case I could be of any help. Looking forward to meet you there.

Re: [Pharo-users] Simple question about Spec

by Julien Delplanque

Indeed, it should be implemented the same way as #minimize and #maximize.

Implementing #activate on WindowModel and delegate to self window of course works. But I am unsure if we want to do it that way, because messages like #maximize #minimize are implemented differently. I don't know what is the preferred way for models to communicate with widgets through the adapter. But if we follow the way of maximize and minimize, an implementation for WindowModel>>#activate could be self changed: #activate with: #() and this needs another change in MorphicWindowAdapter>>#activate self widgetDo: [ :w | w activate ] what do you think? > > > Le 3/2/16 13:35, Julien Delplanque a Ã©crit : > > Ok I found how to do it: >> >> myWidget window window activate. >> >> Some observations: >> "myWidget window" gives a WindowModel which inherits from >> AbstractWidgetModel and does not have #activate message. >> "myWidget window window" gives a SpecWindow which inherits from >> StandardWindow, a morph. >> >> Thanks a lot for the help! >> >> Julien >> >> On 03/02/16 13:16, Sven Van Caekenberghe wrote: >> >>> <window-model> window activate ? >>> >>> On 03 Feb 2016, at 13:03, Julien Delplanque <julien(a)tamere.eu> wrote: >>>> >>>> >>>> On 03/02/16 12:33, Stephan Eggermont wrote: >>>> >>>>> On 03-02-16 12:14, Julien Delplanque wrote: >>>>> >>>>>> Hello, >>>>>> >>>>>> I can't find the answer by browsing classes comments nor methods so I >>>>>> ask the question here :). >>>>>> >>>>>> Is it possible to put a WindowModel on top of all other windows >>>>>> opened? >>>>>> If it is, how? >>>>>> >>>>> I'm not sure where you are looking for, but did you look at the >>>>> WorldModel? >>>>> >>>>> Stephan >>>>> >>>>> >>>>> >>>>> How, a little precision, when I say "Is it possible to put a >>>> WindowModel on top of all other windows opened?"
