Thank you both, PositionableStream>>upToAll worked fine !

Re: [Pharo-users] how to add a class via programatic refactoring

It checks that the class does not already exist. And check the preconditions.

Re: [Pharo-users] how to add a class via programatic refactoring

by Peter UhnÃ¡k

What's the practical difference between calling ``` (RBAddClassRefactoring addClass: #SomeClass superclass: #Object subclasses: {} category: #Category) primitiveExecute; changes. ``` and ``` Object subclass: #SomeClass instanceVariableNames: '' classVariableNames: '' package: 'Category' ``` likewise for the attribute? I am doing source code generation in one project and using the latter approach, so I am curious about the benefit of the first one.

Leonardo, You could try PositionalStream>>#upToAll: But watch out: if the substring does not occur, it will effectively read #upToEnd HTH, Sven > On 09 Feb 2016, at 13:29, Leonardo Silva <leonardo.humberto(a)gmail.com> wrote: > > 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 >

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

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.

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.

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