Canadian Smalltalk Competition

by Ben Coman

Richard Eng visited the Pharo community a while ago being very enthusiastic about his Smalltalk Renaissance project. His strategy didn't end up fitting the community, but I find his kickstarter to run a Smalltalk coding competition for secondary students interesting. Apart from straight altruism to support it, providing a wide exposure of students to the concept of Smalltalk just before they enter university should generate some spillover to our communities. A rising tide lifts all ships. And community networking is a funny thing, some of those students will have parents in strategic positions who would never otherwise be exposed to Smalltalk. Its worth considering.... https://www.kickstarter.com/projects/1520902870/canadian-smalltalk-competit… cheers -ben

Display morph in GT inspector

by Norbert Hartl

I tried to figure out how I can display a morph inside a GT inspector presentation. How can I add a non-string representation to a composite given in an gtAnyIn: method? thanks, Norbert

If you have the amount auf characters you want to omit you can do 'BormParticipant' allButFirst: 4 Norbert > Am 06.04.2015 um 12:34 schrieb Peter UhnÃ¡k <i.uhnak(a)gmail.com>: > > Hi, > > am I really blind, or is there no way to do something like > 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'" > or > 'BormParticipant' copyFrom: 5 "-> 'Participant'" "OrderedCollection knows this" > > I can do copyFrom:to:, but that requires asking the size of the string, which is (in my eyes) ugly. > > So is there better (=single message) way? > > Thanks, > Peter

Hello Peter, Finder can't find when you need to compose two messages, this one does it: ('BormParticipant' splitOn: 'Borm') last Hilaire Le 06/04/2015 12:34, Peter UhnÃ¡k a Ã©crit : > Hi, > > am I really blind, or is there no way to do something like > 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'" > or > 'BormParticipant' copyFrom: 5 "-> 'Participant'" "OrderedCollection > knows this" > > I can do copyFrom:to:, but that requires asking the size of the > string, which is (in my eyes) ugly. > > So is there better (=single message) way? > > Thanks, > Peter -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

String operations

by Peter UhnÃ¡k

Hi, am I really blind, or is there no way to do something like 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'" or 'BormParticipant' copyFrom: 5 "-> 'Participant'" "OrderedCollection knows this" I can do copyFrom:to:, but that requires asking the size of the string, which is (in my eyes) ugly. So is there better (=single message) way? Thanks, Peter

Re: [Pharo-users] Data scrapping in pharo: converting text with dates in Spanish

by Paul DeBruicker

copyFrom:14 to: 17 copies 4 characters. You're testing a 4 character long string against a 3 character long string. That's why the test fails. Either change it to copyFrom: 15 to:17 or add a trimBoth send to month temp var. You may have an easier time not using temp variables in the workspace as you can then explore/inspect them more easily to see what they contain after the calculation has or has not done what you expected.

Data scrapping in pharo: Extracting tweets contents

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm making a data scrapper from twitter. I know that twitter API is there, but I would like to make the scrapped data available to anyone, even if the person has not signed an API agreement. Also I think that this kind of external data is important for making agile visualization less self-referential and could bring some interesting examples with the data is common to the usual "netizen". I have some advances that you can test easily executing the code at [1] and I have already scrapped and filled out the data from a twitter profile page. [1] http://ws.stfx.eu/E3LD464QI0GR Now I'm having problems extracting tweets data. If I execute the code at [2] I can get a list of tweets (first 19) and I can explore inside any member of the collection, but I can't make sense of the SoupTag data inside. How can I extract particularly the tweet contents? [2] http://ws.stfx.eu/JXYM7W7WL1H9 Any help with this will be greatly appreciated. Cheers, Offray
