[OT] Two questions about coding with Amber
by Sebastian Sastre Feb. 2, 2015

Feb. 2, 2015

Hi there! I hope this not get too off topic here but I consider Amber and Pharo to be kind of best friends and we need more data/input for this to improve the development experience. Did you tried or use Amber <http://amber-lang.net/>? We want to have some insight and understand better this two basic things about how Amber users use it to code. If you use Amber or have used it for any purpose (including trying it out), please answer this: http://goo.gl/forms/DZ2djBRW9E <http://goo.gl/forms/DZ2djBRW9E> I'm going to share results after we close the poll. Thanks!

Small Chat App
by Luc Fabresse Feb. 2, 2015

Feb. 2, 2015

Hi all, Raining sunday ;-) [image: Images intÃ©grÃ©es 1] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "In Pharo 3.0" Gofer it smalltalkhubUser: 'LucFabresse' project: 'Grimoire'; package: 'ChatApp'; load. ChatApplication startLocalExample. ChatApplication stopLocalExample ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This a 1st draft version of a Chat Application that works. It is implemented in plain Socket with an ad hoc text protocol. a *lot* should be improved, done or added: - write tests (it is always a pain to write for client/server apps so here I skip them :-() - ensure that everything is correctly destroyed/cleaned (processes, sockets, streams, ...). it seems but... needs testing - refactor to use SocketStream? - better modularization of commands - another implementation using Zinc but it would imply using HTTP Enjoy, Luc

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.

Pointer Detective - Inspecting an Object (instance) and Doing a "PointerDetective openOn: self." leads to a System Error in Pharo?
by Mircea S. Feb. 1, 2015

Feb. 1, 2015

The object is a WhateverRoot instance (subclass of WAComponent) that has "canBeRoot ^true." Am I doing something wrong? PS. My "eagle eye" caught a typo on line 9 of the error. "'Orginal error:' ,title asString.". Maybe, just maybe... More info and an printscreen here: http://stackoverflow.com/questions/28210014/pointer-detective-inspecting-an…

Editable text field inside Roassal/Trachel Canvas
by Peter UhnÃ¡k Feb. 1, 2015

Feb. 1, 2015

Hi, is it possible to embed (any) editable text field inside Roassal? I managed to add the editor morph inside Trachel's athens canvas, however there is no way I can access it... my guess is that TRMorph takes all the events, or drawing the morph on the canvas destroys something. I tried it with PluggableTextFieldMorph (shows the border of the edit field, but no text), and TxTextEditorMorph (shows text). Is there any way around this? Adding the morph inside AthensWrapMorph works correctly, so my guess is that TRMorph must be doing something... perhaps I should also add it as a submorph of TRMorph somehow? My testing code follows: ------------------------------------------------ "opening the canvas and adding custom shape" trCanvas := TRCanvas new. text := SBEditableTextShape new. trCanvas addShape: text. trCanvas open. ------------------------------------------------ ------------------------------------------------ "content of SBEditableTextShape - same as the attachement" 'From Pharo4.0 of 18 March 2013 [Latest update: #40470] on 1 February 2015 at 10:13:04.069249 pm'! TRShape subclass: #SBEditableTextShape instanceVariableNames: 'txMorph txModel wrapMorph textMorph' classVariableNames: '' poolDictionaries: '' category: '_Sandbox'! !SBEditableTextShape methodsFor: 'drawing' stamp: 'PeterUhnak 2/1/2015 22:10'! drawOn: aCanvas " aCanvas fullDrawMorph: textMorph." aCanvas fullDrawMorph: txMorph.! ! !SBEditableTextShape methodsFor: 'initialization' stamp: 'PeterUhnak 2/1/2015 22:07'! initialize | string | super initialize. string := 'quick brown fox jumps over the lazy dog'. txModel := string asTxModel. txMorph := TxTextEditorMorph text: txModel. txMorph extent: 150 @ 50. textMorph := PluggableTextFieldMorph new. textMorph extent: 150 @ 50. textMorph setText: string. textMorph ghostText: 'ghost text'.! ! ------------------------------------------------ Any help is appreciated, Peter

Seaside - How do I install Scriptaculous on a clean Seaside install (via Configuration Browser) on Pharo?
by Mircea S. Feb. 1, 2015

Feb. 1, 2015

I used the method described here to install Seaside3 on Pharo. All is well, but Scriptaculous doesn't come preinstalled. How do I get it? Seaside3 : 1: Go to the configuration manager 2: Select the Seaside 3 configuration. Click on Install. 3: Wait while it loads. Takes a couple of minutes on an i7 and a decent network link. 4: Open a Workspace and start a ZincServerAdaptor on the port you like (here 8080): ZnZincServerAdaptor startOn: 8080. (then CMD+d for Do It) 7: Access Seaside from your browser. 8: Install Scriptaculous, but how?

Seaside on Pharo - Why the weird jQuery integration syntax compared to Scriptaculous?
by Mircea S. Feb. 1, 2015

Feb. 1, 2015

Seaside on Pharo - Why the weird jQuery integration syntax compared to Scriptaculous? Ex1: html scriptaculous sortable onUpdate: (html scriptaculous... etc). html jQuery new sortable onStop: (html jQuery... etc). Ex2: html scriptaculous effect id: helpId; toggleAppear. (html jQuery id: helpId) slideToggle: 1 seconds. The way jQuery and Scriptaculous were integrated 'seems' similar. Can anyone explain what design change took place between the two and it's effect on syntax? PS. Especially in the last example.
