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]]])! !

Depending on your exact needs, you might be better of with the QCMagritte based multi-language support. https://www.youtube.com/watch?v=cTut44Xs3_U To try download a QCMagritte image from https://ci.inria.fr/pharo-contribution/job/QCMagritte/ start a seaside adapter ZnZincServerAdaptor startOn: 8081. browse to the qcmagritte application. http://localhost:8081/qcmagritte tutorial is at http://localhost:8081/ Stephan

[ann] pillar support in gtinspector
by Tudor Girba Sept. 8, 2014

Hi, Documentation is important. To make it more likely and more enjoyable for people to write more of it, I teamed up with Andrei and Jan to build up support for Pillar in the GTInspector. The current solution brings the following: - Pillar specific syntax highlighting including Shout highlighting for code snippets - Embedded files validation and preview possibility - Quick browsing of Pillar book projects when inspecting the book folder - Class comment rendering using Pillar syntax when inspecting the class object - Text editor support for custom highlighting in Glamour (using Rubric for now) - Island parsing for quick specification of incomplete parser You can learn more about it here: http://www.humane-assessment.com/blog/writing-pillar-books-with-the-gtinspe… [image: Inline image 1] There is much more to do in this direction, and I would be happy to inspire some of you to join forces. Please let us know what you think. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
