Data scrapping in pharo: converting text with dates in Spanish
by Offray Vladimir Luna CÃ¡rdenas April 6, 2015

April 6, 2015

Hi all, I'm making a small data scrapper[1] in pharo to feed some visualizations. The data I'm scrapping contains strings with dates in Spanish like '16:21 - 15 de jun. de 2011' and I would like to convert them to proper dates in Smalltalk. So I started prototyping an Small script at [2], but the problem is that monthIndex at: month doesn't work because 'jun' is not in the dictionary (please refer to [2] for details). This is motivated by month = 'jun' giving false, but when I inspect month its content is 'jun', so I think that I'm missing something important. [1] http://smalltalkhub.com/#!/~Offray/Dataviz [2] http://ws.stfx.eu/IOMTYZ0N9W29 So here come my questions: a). How to get "monthIndex at: month" working properly so I can get '06' as the proper month index for the month 'jun' (junio).? b) Why month = 'jun' gives false? c) There is any way to convert strings which has months in different languages (for example Spanish) more directly? Thanks, Offray

Data scrapping in pharo: Extracting tweets contents
by Offray Vladimir Luna CÃ¡rdenas April 6, 2015

April 6, 2015

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

Getting the last keyboard key pressed when using a RubScrolledTextMorph
by Johan Fabry April 6, 2015

April 6, 2015

Hi all, the code below gives me the number representing the last keystroke. It is a bit of a hack, so I was wondering if there is a cleaner way to do this when using a RubScrolledTextMorph (I tried subscribing to different announcements to no avail).

Object-oriented state-frozen logging
by Peter UhnÃ¡k April 6, 2015

April 6, 2015

Hi, this may be a bit tall order and I am not sure if possible, however I would like to know the state of objects at certain points. Currently what I would do is something like self log: 'anObject someProperty:'; logCr: anObject someProperty. however this is not very practical. So I would like something like self fronzenLog: anObject and then I could inspect the logger and see the state of the whole objects. Using debugger and stepping through it is not really practical because I need to observe several possible objects that are in this function at very different times. Is this possible? Is there a better/somewhat better way to do something like this? Any pointers appreciated. Peter

Canadian Smalltalk Competition
by Ben Coman April 6, 2015

April 6, 2015

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

Association postcopy (Pharo 3)
by Hartmut April 6, 2015

April 6, 2015

Hi, the Dictionary>>postCopy comment reads: "Must copy the associations, or later store will affect both the original and the copy However Association(Object)>>copy will neither copy 'key' (thats what I expect) nor 'value' (that makes the copy fail). I checked an older version of Squeak and VisualWorks 7 and found that also there Association misses a postCopy. My workaround for a Dictionary copy reads "... associationsDo: [ :a | a value: a value copy ] ". Does anybody know why Association does not contain this code in a postCopy method ?

IconFactory - utility for creating icons in Pharo
by Peter UhnÃ¡k April 6, 2015

April 6, 2015

Hi, since I've been making new icons lately for my project I was frustrated with constantly copying code and methods around... so I've made a small utility for it http://smalltalkhub.com/#!/~peteruhnak/IconFactory â on top of creating the icons it can add extra stuff like GTInspector support. Any feedback appreciated. Peter
