athens font rendering and subpixel antialiasing
by Nicolai Hess Feb. 2, 2015

Feb. 2, 2015

Anyone knows, why the text rendering with athens (cairo) looks slightly different than the freetypeplugin one? attached is a screenshot, left side athen right side (morphic) freetypeplugin. It "looks" like the cairo freetype fontrendering uses CAIRO_ANTIALIAS_GRAY, no colored subpixel antialiasing. But the font options do define antialiase subpixel and a subpixel ordering RGB. This is on windows 7 with the latest vm, does it look different on other Systems? nicolai

Feb. 2, 2015

There is an offering at Thales for an internship for a student (in france): > Thank you for your interest in a career with Thales. Below you will find a link to the job that you found on the mobile website. When clicked, this link will allow you to view the job details again and Apply for the job. > > > STAGE Multi fenÃªtrage sous Pharo Smalltalk (Logiciel) (H\F) <http://jobs.thalesgroup.co.uk/fr/france/software-engineering/jobid6338665-s…> Job ID: 1413963 Job Location: Brest, Bretagne, France Position Type: Software Engineering Business Unit: Thales Systemes Aeroportes S.A. Post Date: 01/12/2015 Partout oÃ¹ des dÃ©cisions critiques doivent Ãªtre prises, Thales est prÃ©sent. Sur les marchÃ©s que nous servons -Â aÃ©ronautique, espace, transport terrestre, sÃ©curitÃ©, dÃ©fenseÂ -, nous assurons la maÃ®trise de la Â« chaÃ®ne de dÃ©cision critique Â» pour aider nos clients Ã choisir la meilleure option et Ã agir en consÃ©quence. Lâexpertise de sesÂ 65 000 collaborateurs, sa puissance technologique et sa prÃ©sence opÃ©rationnelle dansÂ 56 paysÂ font ainsi de Thales un acteur clÃ© de la sÃ©curitÃ© des citoyens, des infrastructures et des Etats. <> La Global Business Unit SystÃ¨mes de Mission de DÃ©fense, leader europÃ©en et troisiÃ¨me acteur mondial sur ses marchÃ©s par sa taille et son niveau technologique, conÃ§oit des Ã©quipements et des systÃ¨mes de mission pour avions, hÃ©licoptÃ¨res et drones militaires, bÃ¢timents de surface et lutte sous la mer. Elle propose Ã©galement une offre complÃ¨te de services de maintenance en condition opÃ©rationnelle. Thales SystÃ¨mes AÃ©roportÃ©s, filiale du Groupe Thales (3200 collaborateurs) regroupe diffÃ©rents domaines dâactivitÃ©s : systÃ¨mes de mission pour avions de mission et drones, Radars aÃ©roportÃ©s de combat et surveillance, SystÃ¨mes de Guerre Electronique (air, terre, mer, espace), Soutien et Service Client. Dans le cadre de notre dÃ©veloppement, nous recherchons un(e) : STAGE : Multi-fenÃªtrage sous Pharo Smalltalk (Logiciel) â H/F BasÃ©(e) Ã Brest (29) Contexte : Notre entitÃ© dÃ©veloppe rÃ©guliÃ¨rement des maquettes dâinterfaces homme-machine (IHM) innovantes. Lâinnovation se situe autant au niveau de lâergonomie quâau niveau du design graphique visuel ou des Ã©lÃ©ments dâinteraction. Le maquettage est souvent utilisÃ© en sÃ©ance avec les opÃ©rationnels, dâoÃ¹ lâemploi dâun langage dynamique comme Smalltalk qui permet la modification rapide (et en sÃ©ance) du code et des Ã©lÃ©ments dâinteraction. Le maquettage/prototypage des interfaces Homme-Machine est donc actuellement rÃ©alisÃ© sous SMOCK, un framework de maquettage dÃ©veloppÃ© en Smalltalk. Smalltalk Pharo est un excellent candidat pour la plateforme finale d'exÃ©cution du framework de maquettage/prototypage, cependant, certaines limitations de Pharo nous empÃªchent de l'utiliser de maniÃ¨re industrielle. Missions : Nous souhaitons expÃ©rimenter un environnement de maquettage sous Pharo, cependant, cette derniÃ¨re limite lâaffichage des IHM Ã lâintÃ©rieur d'une seule fenÃªtre de l'OS. Nous souhaitons, en relation avec la communautÃ© Pharo, dÃ©velopper le multi-fenÃªtrage. Le stagiaire devra implÃ©menter un mÃ©canisme permettant l'ouverture et gestion de fenÃªtres multiples dans les OS Windows et Linux Ã minima. Une rÃ©utilisation de code existant dans la communautÃ© Pharo et une reversion de code en OpenSource est envisageable. Le candidat sera l'interlocuteur entre Thales et la communautÃ© Pharo. Le candidat Ã©valuera diffÃ©rentes solutions de multi- fenÃªtrage sous diffÃ©rents critÃ¨res (performance, robustesse de la solution, portabilitÃ© de la solution...). La solution devra anticiper le futur et prÃ©voir d'afficher des contenus visuels variÃ©s (vidÃ©o, primitives de dessin 2D, OpenGL...). L'objectif sera de dÃ©velopper un prototype IHM multi-fenÃªtres de dÃ©monstration sur Pharo afin de dÃ©montrer les nouvelles capacitÃ©s et un aperÃ§u des performances. Formation souhaitÃ©e : Master 2 Pro ou 3Ã¨me annÃ©e d'Ecole d'IngÃ©nieur. Connaissances souhaitÃ©es : Le stagiaire devra avoir une connaissance du Smalltalk ou Ãªtre motivÃ© par lâapprentissage de celui-ci. Il devra ensuite Ãªtre motivÃ© par la conception dâinterface homme machine de nouvelles gÃ©nÃ©rations et novatrices. PÃ©riode souhaitÃ©e et durÃ©e : Ã partir de janvier 2015 pour une durÃ©e de 6 mois.

How to browse a given keymap category
by stepharo Feb. 1, 2015

Feb. 1, 2015

Hi I wanted to fix https://pharo.fogbugz.com/default.asp?14845 Selecting a class and pressing command B+M raises an error so either we should check that the selected method is not nil (I do not like that much) or the key binding should not work on classes (preferred solution). buildBrowseShortcutsOn: aBuilder <keymap> (aBuilder shortcut: #browseSenders) category: #NautilusGlobalShortcuts default: $b command , $n command do: [:target | target browseSendersOfMessages ] description: 'Browse senders of the selected method'. (aBuilder shortcut: #browseClassRefs) category: #NautilusGlobalShortcuts default: $b command, $n command shift do: [ :target | target browseClassRefs ] description: 'Browse class references'. (aBuilder shortcut: #browseImplementors) category: #NautilusGlobalShortcuts default: $b command , $m command do: [:target | target browseMessages ] ^^^^^^^^^^^^^^^^^^^^^^^^^ description: 'Browse implementors of the selected method'. a "bad solution to my eye" is browseMessages self selectedMethod iifNil: [^ self]. <<<<< self browseMessagesFrom: self selectedMethod selector Now my question is then how can I find the different categories of bindings such as #NautilusGlobalShortCuts I tried to inspect a builder from the debugger but I got lost and should run to catch a train.

OSProcess stdErr issue on Windows
by Ben Coman Feb. 1, 2015

Feb. 1, 2015

On Windows 7, trying to execute a non-existent program as follows... OSProcess command: 'notepadXX.exe' ...causes an MNU in ExternalWindowsOSProcess>>value. This is due to writing to stderr where "self initialStdErr" returns nil, seemingly due to ExternalWindowsOSProcess missing the #initialize and #setDefaults of E xternalUnixOSProcess. Now I understand that stderr is problematic in general on Windows. The following statements... OSProcess thisOSProcess stdErr nextPutAll: 'test'. FileStream stderr nextPutAll: 'test'. ...both work fine on OSX, but fail on Windows with the error "FileWriteError: File stderr is closed" The result is the same on both Pharo 4 and Squeak 4.5. (Squeak also brings up a bottom message bar saying... "# To disable: F2 -> 'debug options' -> 'show console on errors' WARNING: Manufactured file handle detected!") Pharo has a workaround for the general issue by creating a disk file named 'stderr' as follows... FileStream class >> standardIOStreamNamed: moniker forWrite: forWrite self flag: #todo. "This is an ugly hack, while waiting for a real fix for windows. There several problems with this approach, but it allow us to run tests, etc." Smalltalk os isWin32 ifTrue: [ [ ^ MultiByteFileStream forceNewFileNamed: moniker asString ] on: CannotDeleteFileException do: [ "HACK: if the image is opened a second time windows barks about the already opened locked file" ^ MultiByteFileStream forceNewFileNamed: moniker asString, '_', (Random new nextInt: SmallInteger maxVal) asString ]]. So to address the MNU for OSProcess? 1. wrap the "self initialStdErr" with an #ifNil: check 2. Squeak adopt the Pharo workaround, then lean on that to define #initialize and #setDefaults for ExternalWindowsOSProcess 3. real fix for stderr (outside of OSProcess?) 4. wont fix 5. other? Note that this is not a burning issue for me. I am just cleaning out old issues that I logged in the Pharo bug tracker. If the answer if (4.) I'll just close the issue [1]. For both Squeak and Pharo, I loaded ConfigurationOfOSProcess-ThierryGoubier.33 from... MCHttpRepository location: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo40/main' (Perhaps someone with access can copy that to the main repo) cheers -ben [1] https://pharo.fogbugz.com/default.asp?11615
