Github API on github

by Guillermo Polito

Hi guys, I extracted and extended some of the github API from iceberg, so it can be used as a standalone project. Maybe this is useful for somebody. https://github.com/guillep/github-api It should be easy to extend and add new functionalities, so don't hesitate if you need some missing request :) Guille -- Guille Polito Research Engineer Centre de Recherche en Informatique, Signal et Automatique de Lille CRIStAL - UMR 9189 French National Center for Scientific Research - *http://www.cnrs.fr <http://www.cnrs.fr>* *Web:* *http://guillep.github.io* <http://guillep.github.io> *Phone: *+33 06 52 70 66 13

Re: [Pharo-dev] Help for the mooc

by Ben Coman

Was this fixed by replacing the redirect with an actual file? I went to look at http://pharo.org/web/files/pharo.png using Chrome "F12" Develop Tools to view the redirect, and IIUC I directly got the PNG itself. Just checking I'm interpreting that correctly. cheers -ben On Wed, Oct 18, 2017 at 2:33 PM, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > Tx! > I should fix it but probably the videos are still using the old one. > > On Tue, Oct 17, 2017 at 10:36 PM, Sven Van Caekenberghe <sven(a)stfx.eu> > wrote: > > > > > >> On 17 Oct 2017, at 22:29, Stephane Ducasse <stepharo.self(a)gmail.com> > wrote: > >> > >> Hi > >> > >> students have a problem with the following in Pharo 50 (we could not > upgrade) > >> > >> (ZnEasy getPng: 'http://pharo.org/web/files/pharo.png') asMorph > openInWindow > >> > >> > >> ConnectionClosed : connection closed while waiting for data > >> > >> And well this is super annoying. > >> > >> Stef > > > > This is fixed in later versions.

Re: [Pharo-dev] UnifiedFFI Docs

by Todd Blanchard

I have found the problem with VoidPointer3 generating accessors. No idea how to contribute back a fix but this is what I've found. FFITypeArrayType>>annonymousClassCreator ^ String streamContents: [ :stream | stream nextPutAll: '(FFITypeArray ofType: '; print: (self objectClass type isPointer ifTrue: [self externalTypeWithArity printString] ifFalse: ['#',self objectClass type class]); nextPutAll: ' size: '; print: self objectClass numberOfElements; nextPutAll: ')' ] Recalling that we are trying to come up with an accessor that can pull out a void*[3], this produces '(FFITypeArray ofType: #FFIVoid size: 3)' which produces an error as FFIVoid's size is undefined. In general, this will be wrong for any pointer type and will probably get the size calculation wrong. Doing a little digging I find that FFITypeArray>>ofType: aType size: aSize delegates resolution of aType to FFIExternalType>>resolveType:aType and this can take all kinds of different things including the native type name. It would be better if this generated the native name for pointers. (FFITypeArray ofType: 'void*' size: 3) So I changed it to: FFITypeArrayType>>annonymousClassCreator ^ String streamContents: [ :stream | stream nextPutAll: '(FFITypeArray ofType: '; print: (self objectClass type isPointer ifTrue: [self externalTypeWithArity printString] ifFalse: ['#',self objectClass type class]); nextPutAll: ' size: '; print: self objectClass numberOfElements; nextPutAll: ')' ] and this seems to work fine.

Re: [Pharo-dev] OSWindow in Pharo 6.1 stable

by Ronie Salgado

Hi ClÃ©ment, Last night I was checking again the VM. If I remove the hack in the ioProcessEvents, I can receive the events with SDL2, but as soon as I type on the main Pharo window I get a crash in an objective-c message send by SDL2. I still need to debug SDL2 itself with debugging symbols. I am not sure whether I will be able to fix the problem without modifying SDL2. In the worst case escenario, we will have to move to the minheadless vm.

Anoying bug fond in Artefact running in Windows 10

by casimiro.barreto＠gmail.com

When you insert a jpeg from a file, for some reason the file descriptor (stream) is kept open (at least in the Windows end of things). Then, if a second page is to be generated, the following error is shown: 'MessageNotUnderstood: receiver of "reset" is nil PDFJpegElement>>stream: JPEGReadWriter aJPEGReadWriter JPEGReadWriter(ImageReadWriter)>>on: nil Sample code: aPage := PDFPage new. imageStream := FileStream fileNamed: 'lsi-tec.jpg'. aPage add: ((PDFJpegElement fromStream: imageStream) from: 15 mm @ 20 mm; dimension: 40 mm @ 40 mm). imageStream close. Generated report is in annex The only way to recover is to close pharo, start it again. Then the file descriptor (stream) is released and it is possible to go on. Has anyone faced this problem? How to solve it? Best regards, Casimiro Barreto

I would suggest to load pillar based on version and stable version. I never try development especially because I'm maintaining branches in MC which does not support branches.

Re: [Pharo-dev] Loading GToolkit is broken in latest 7

by Stephane Ducasse

Hi About pillar I'm working on it. Now I only maintain two versions one for Pharo 50 and one for Pharo 60. The new things are happening in Pharo 60. Now this was a bad idea to link Pillar with Magritte only to manage configurations because Magritte is too big to me and full of too many constraints like loading Grease and others. I do not want to spend my time fighting with issues imposed to me. I'm slowly working on freeing Pillar from Magritte but I got stuck and out of energy. Now I will not maintain a version for Pharo 70 alpha because I simply cannot.
