Is the Playground the Workspace?â
by Daniel Roe May 24, 2015

May 24, 2015

Question to Daniel: Did you try to know something about the tool before in the IDE? For example, did you try to read the About of the tool? (I'm trying to determine how useful/accesible are the help features of the tools) To show you what a noob I am - I don't even understand your question. Dan

Is the Playground the Workspace?
by Daniel Roe May 24, 2015

May 24, 2015

I am a complete noob when it comes to Smalltalk. I have chosen both Squeak and Pharo to learn this language. I am doing so just for my own knowledge and to try and keep my aging brain active. I may choose down the road to concentrate on one of the Smalltalk variants but right now I'm going to go with both. My question: All of the documentation refers to a Workspace. Sqeak has one but all I find in Pharo is the Playground. Does the Playground serve as the Pharo Workspace? Thanks for your time, Dan

Alt-tab between windows
by Avdi Grimm May 23, 2015

May 23, 2015

Hey folks! I've dabbled with smalltalk here and there over the years, but recently I've settled in to learn Pharo in earnest. A few of you might have seen the videos I've been putting up; they seem to be making the rounds on Twitter. I just want to say I've felt really welcomed by all the people who have commented with helpful tips, or offered to help with my exploration :-) I've run into my first big blocker as a newcomer. Like many programmers I'm a fan of keeping my hands on the keyboard. Now, I'm more flexible on this than some. I recognize that Pharo is a visual environment, and it makes sense to explore it with a mouse. And some interactions just make more sense with a mouse. That said, no matter what windowing environment I'm in, I find the ability to quickly cycle between windows without leaving the keyboard pretty crucial. One Windows or Ubuntu I would normally do this with Alt-Tab or Super-Tab. On MacOS it's Cmd-Tab. I've been trying to figure out how to do this in Pharo. I've looked for answers with Google, SO, and on IRC, and I've come up blank. I'm starting to think it can't be done. So, I've come here for your help. Is there a way to cycle between windows? Or is anyone working on it? Or, perhaps, am I missing an element of the Pharo programming workflow which renders it unneeded? Many thanks, -- Avdi

[OT] Pharo pi machine

Got my Raspberry Pi B+ with a TontecÂ® 3.5 touch screen display to bootstrap into Pharo. The Raspberry Pi from CI (https://ci.inria.fr/pharo/view/RaspberryPi/) worked out of the box on Raspbian. Nice!

Generate latex from Pharo
by Julien Delplanque May 22, 2015

May 22, 2015

Hi everyone, Is there any framework to generate latex code from Pharo? I would like to give a latex representation to some objects so I can export the latex code to a file I would include to my latex main file (for example). For example for a matrix I would like to do something like: fileStream nextPutAll: myMatrix asLatex. to have something like: \begin{pmatrix} 1& 2\\ 3& 4 \end{pmatrix} in the file. I used to do it with pylatex in Python and I wonder if something equivalent already exists in Pharo? Regards, Julien

Any way to create multiple accessors in one time?
by Julien Delplanque May 22, 2015

May 22, 2015

Hi everyone, The subject is explicit enough... I find it annoying when I have to do lots of click to create each accessors using the gui... :) I suppose it's possible to modify the browser to do that but I wonder if anyone already did it? Regards, Julien

Re: [Pharo-users] Pharo first timer
by Jan BlizniÄenko May 22, 2015

May 22, 2015

Hello, I'm not so experienced ST user and I know your post is meant for the developers more than other users, but I would like to join the discussion and maybe help anyway :) (1) It is true that Nautilus (class browser) needs a lot of time to display greater amounts of classes. For example displaying whole Roassal2 package with 319 classes for first time takes 12 seconds on my PC and I always curse myself for even clicking on it, so displaying all classes in Pharo (which is almost 10 thousand in basic image) takes a lot of time, but honestly, I have never needed to display all classes in whole Pharo. (2) Class is "abstract" and should not have any instances. allInstances method returns only instances of receiver, but not of subclasses of receiver. Getting instances of Metaclass is something quite different - it returns all "classes of classes". Maybe take a look at this: http://pharo.gforge.inria.fr/PBE1/Metaclasses/figures/TranslucentMetaclassC… Method allSubclasses gives you everything recursively connected by empty arrows (subclasses) and allInstances gives you everything connected by double filled arrows (instances).

Fun with pillar and mustache
by Norbert Hartl May 22, 2015

May 22, 2015

I've found some minutes today to play with pillar and mustache. I wanted to know how far I can go when doing some static site generation. The exercise was to simulate a page that has multiple components either in mustache or pillar format. I could do this | masterTemplate masterPillar masterDocument partialPillar partialTemplate finalPillar | masterTemplate := '<master> <head>{{{title}}}</head> <masterContent> {{{content}}} </masterContent> </master>'. masterPillar := '{{title: This is the title of the master!}} !masterheading This text is contained in the master pillar template {{{{{>phase2Template}}}}}'. partialPillar := '!{{{{{{title}}}}}} Some text in the partial template before the content... {{{{{{content}}}}}}} ... and after'. finalPillar := 'I''m a text in pillar format that was inserted in a partial mustache template generated from pillar that was inserted in a mustache master template in pillar format that was inserted in a master mustache template'. masterDocument := PRDocumentParser parse: masterPillar readStream. partialTemplate := PRHTMLWriter write: (PRDocumentParser parse: partialPillar readStream). phase1Result := masterTemplate asMustacheTemplate value: masterDocument properties, { 'content' -> (PRHTMLWriter write: masterDocument) } asDictionary. phase2Result := phase1Result asMustacheTemplate value: { 'title' -> 'A partial title'. 'content' -> (PRHTMLWriter write: (PRDocumentParser parse: finalPillar readStream)) } asDictionary partials: { 'phase2Template' -> partialTemplate } asDictionary. and got <master> <head>This is the title of the master!</head> <masterContent> <h1>masterheading</h1> <p>This text is contained in the master pillar template</p> <p><h1>A partial title</h1> <p>Some text in the partial template before the content...</p> <p><p>I'm a text in pillar format that was inserted in a partial mustache template generated from pillar that was inserted in a mustache master template in pillar format that was inserted in a master mustache template</p>}</p> <p>... and after</p></p> </masterContent> </master> That is really cool. Actually pillar and mustache are a good match. FYI, Norbert
