Hapax/CodeFu changes and example script
by HernÃ¡n Morales Durand Jan. 20, 2013

Jan. 20, 2013

Hi guys, For those working in information retrieval, for example for doing td-idf ranking, you can find adapted packages: "Hapax" and "CodeFu" in the BioSmalltalk repository http://ss3.gemstone.com/ss/BioSmalltalk.html . I have translated some VW specific code to Pharo 1.4 (under Windows requires the ProcessWrapper package) and adapted some Hapax methods to work with corpus in different languages. This is an example script for a corpus in Spanish: | corpus tdm documents | corpus := HXSpanishCorpus new. documents := 'el rÃo Danubio pasa por Viena, su color es azul el caudal de un rÃo asciende en Invierno el rÃo Rhin y el rÃo Danubio tienen mucho caudal si un rÃo es navegable, es porque tiene mucho caudal'. documents lines doWithIndex: [: doc : index | corpus addDocument: index asString with: (Terms new addString: doc using: CamelcaseScanner; yourself)]. corpus removeStopwords. corpus stemAll. tdm := TermDocumentMatrix on: corpus. Feel free to integrate to any repository. If you want to add a language just see methods with selectors including "spanish". Cheers, HernÃ¡n

Pharo Association: alone we have little power, but many we are strong

Jan. 19, 2013

Hi guys Just a point: Join the Pharo association because all together we can get some power. For example, I would like that we brainstorm about what kind of effort the association want to sponsor. - real headless image - other network protocols -â¦ So far we are 35 but I really dream about a moment where we will be much more. If you find some value to Pharo and you want to encourage its evolution, this is simple. Stef

HTML parser

What is the most actual HTML parser to date? Researching gave me [1]. All of the discussions were in 2010. So the situation might have changed. Anything newer? better? Anything petit parsers based? thanks, Norbert [1] http://www.squeaksource.com/htmlcssparser.html

[ANN] Headless support for Cog Cocoa VM
by Mariano Martinez Peck Jan. 18, 2013

Jan. 18, 2013

Hello there, For a long time, Pharaoers and Squakers have been asking for headless support in the Cocoa VMs just as we have with Carbon VMs. Carbon is becoming a legacy framework so people needed this. I wanted to thanks Square [i] International <http://www.square-i.net/> for sponsoring me to implement such a support. Not only have they sponsored the development but they have also agreed to release it under MIT license for the community. This headless support will be included in the official Pharo VM and will be, therefore, accessible to everybody. The project is not yet finished but I do have a demo/prototype that I wanted to share with you so that you can test it and give me feedback. This VM should only work starting at OSX 10.6. *How to use it?* Basically it works this way: to have headless, just edit the Info.plist and set the flag LSBackgroundOnly to 1 (add the key if it is not present): <key>LSBackgroundOnly</key> <true/> When doing this, you don't even need the -headless anymore since, setting LSBackgroundOnly to 1, will cause the same effect (being the flag almost mandatory). If you don't want headless, put it to false or don't even put the key. If you don't set LSBackgroundOnly to 1 but send -headless, the VM will still be headless but you will see a little flash. If this flash bothers you, then set the flag. I am trying to get a way to avoid the "flash" while also avoiding to set LSBackgroundOnly to 1, but I still couldn't find it. Anyway, I think we can live with the current situation. *How to test it?* You should run the image with something like RFB or Seaside or whatever you can and then confirm if it is working even if you are headless. As a matter of testing, I saved an image with seaside running in the port 5555. You can get both, this Seaside image and the VM with headless from: https://www.dropbox.com/sh/r7qk49bxywk2xce/6N7-fdyx6V So if you run the VM headless with that image and go to localhost:5555, you should see that Seaside is running. I would appreciate if you can test it. And please let me know in which version of OSX you tried. Of course, the more of you who can test it, the better. Notice that this VM was compiled with LLVM GCC 4.2 and it may have some problems in older OSX versions (but I think it shouldn't). I still couldn't compile a VM with GNU GCC 4.2 as I get a crash :( *Expected results?* In headless mode, anything should be displayed (no window, no menu, no item in the dock and nothing appear when switching apps). When running headfull, everything should be normal. *Where is the code? *The code I have modified to the VM is committed to my own fork of the VM: https://gitorious.org/~marianopeck/cogvm/marianopecks-blessed Once the code is ready, I will do a pull request so that it can be integrated. Thanks everyone for the testing and feedback. Once again, thanks Square [i] International for sponsoring this great feature. Also thanks Esteban Lorenzano and Mark Smith for their incredible help. This was just the first prototype. I will keep you informed about possible progress. Best regards, -- Mariano http://marianopeck.wordpress.com

Problem joining Pharo Association
by MartinW Jan. 17, 2013

Jan. 17, 2013

Hello, i have problems joining the Pharo Association. As i could not find a support email address, i post here. Here's what i did: (1) I set up an account with the same email address i use for this post. At this moment i was not asked to pay anything. (2) I read that my account is "inactive" and i could "renew" my subscription - which i did. (3) I payed 40 Euro via PayPal and received an receipt from PayPal. (4) 2 hours later my Pharo Association account is still "inactive" and i am still asked to "renew". (5) While i can login, i am not listet in the member list. So i hope someone will read the problem here or someone can point me to a support address. Best regards, Martin. -- View this message in context: http://forum.world.st/Problem-joining-Pharo-Association-tp4663746.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

String>>withoutTrailingDigits

Jan. 16, 2013

Hi folks, Today I stumbled on a strange behavior, the message withoutTrailingDigits not only removes trailing digit but also removes the leading ones. If you evaluate this: or this: you can see the problem. I've just submitted a bug here: http://code.google.com/p/pharo/issues/detail?id=7272 -- View this message in context: http://forum.world.st/String-withoutTrailingDigits-tp4663739.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
