Is anyone interested in developing a package for Google's Data API?
by Andy Burnett Sept. 11, 2014

Sept. 11, 2014

I use Google's spreadsheet and word processor a lot. I would love to be able to access the data through Pharo. I can envisage all sorts of use-cases such as manipulating data collected through the spreadsheet forms, through to generating slide shows by writing to their presentation app. The thing that has held me back is the lack of a package which presents e.g. Spreadsheet as an object with a collection of methods. There are libraries for Java/Python/etc., but nothing - that I am aware of - for Pharo. Would anyone be interested in developing one? I could certainly contribute some funds towards the effort, and others may be able to do likewise. Cheers Andy á§

Strange colour reversal on the Spec site
by Andy Burnett Sept. 11, 2014

Sept. 11, 2014

Hello, I am posting here, because I couldn't find a Spec specific list. Two things: 1. The colour scheme for all the code examples on the site seems to have gone very odd. The text is now a light blue/green on a white background. Almost completely illegible. Has someone changed a css file? 2. I noticed in the news section that the license has changed to GPL, because of a disagreement with the direction of Pharo. Could someone explain what the disagreement was, and whether this is something we should be concerned about? Cheers Andy á§

Hi, This is just a short mail to let you know whats happening here on the Pharo/Roassal front. We will be starting our workshops on what we I call Visual Data Narratives. Details (in Spanish) here: http://hackbo.co/hackboweb/eventos/evento/338 Cheers, Offray ps: I will show the Moose outliner, in its alpha stage. Hopefully the threads where I ask how to solve the problems will move a little more and we will be able to integrate this to the workshops memories building.

New compiler: variable and recursive bloc of code
by Hilaire Sept. 10, 2014

Sept. 10, 2014

Hello, I noticed this change described bellow and I just want to have confirmation about it: The new Pharo 2.0 compiler need to have variable assigned with a value before it used in a recursive bloc of code. Of course it is a bit inelegant. Or is it something else and does it need to be reported? Thanks to let me know Hilaire For example this Dr. Geo code break in Pharo 2.0: | triangle c | triangle := [:s1 :s2 :s3 :n | c segment: s1 to: s2; segment: s2 to: s3; segment: s3 to: s1. n > 0 ifTrue: [triangle value: s1 value: (c middleOf: s1 and: s2) hide value: (c middleOf: s1 and: s3) hide value: n-1]. [...] ]. It must be changed to: | triangle c | triangle := []. <= CHANGE HERE triangle := [:s1 :s2 :s3 :n | c segment: s1 to: s2; segment: s2 to: s3; segment: s3 to: s1. n > 0 ifTrue: [triangle value: s1 value: (c middleOf: s1 and: s2) hide value: (c middleOf: s1 and: s3) hide value: n-1]. [...] ]. -- Dr. Geo - http://drgeo.eu iStoa - http://istao.drgeo.eu

FFI callbacks
by Annick Fron Sept. 9, 2014

Sept. 9, 2014

In order to use the callbacks, I need to write a pragma in the Callback class for the signature. My signature is something like (where ulong means pointer) void (ulong ulong long long ulong) Can you help me ? Here is an example for another signature : !Callback methodsFor: 'signatures' stamp: 'eem 11/1/2010 16:40'! intcharstarRetint: callbackContext sp: spAlien <signature: 'int (*)(int, char *)' abi: 'IA32'> ^callbackContext wordResult: ((block value: (spAlien signedLongAt: 1) ~= 0 value: (Alien forPointer: (spAlien unsignedLongAt: 5)) strcpyUTF8) ifNil: [0] ifNotNil: [:result| result isInteger ifTrue: [result] ifFalse: [result == true ifTrue: [1] ifFalse: [0]]])! !
