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

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

Spec TreeModel dynamic contents
by webwarrior May 21, 2015

May 21, 2015

I want to make a tree using TreeModel that reacts to changes in underlying data - when an item changes, tree node for that item should update its state (recompute its children, etc.). Rebuilding the whole tree is ok, as long as selections and collapsed/expanded state of nodes are preserved. Using #updateTree however resets all these things. And there is no easy way to save/load them either - #selectedItems/#selectedItems: work with TreeNode instances that get reset, and collapsed/expanded states of nodes are simply unaccessible from TreeModel. I also tried subclassing TreeNodeModel. But I found no way to update underlying UI widget. There is a huge mess involving TreeNodeModel, MorphicTreeNodeAdapter, SpecTreeNodeModel, and MorphTreeNodeMorph. The only option left is to extract all needed information from TreeNodeModel hierarchy (preserving the tree structure) before update, and then try to reapply it to newly created hierarchy. Or is there an easier way? -- View this message in context: http://forum.world.st/Spec-TreeModel-dynamic-contents-tp4827440.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Reminds me a lot onto the old Whsiker browser we had back in the days in Squeak Smalltalk: http://www.fit.vutbr.cz/study/courses/OMP/public/software/sqcdrom2/Packages… Havent done much with Squeak after we forked into Pharo but it may be that it is still running in a recent Squeak version out of the box. But one can try squeak.org or ask on squeak-dev list. Bye T.

Smalltalkhub password reset
by mtk May 20, 2015

May 20, 2015

Hi, I lost my password for smalltalkhub. I read some older messages in the interwebs that one has to directly ask Nicolas Petton for resetting the password, but this didn't work. Is there another way? Maybe a password reset mechanism would be fine... :-) Best Marcus -- View this message in context: http://forum.world.st/Smalltalkhub-password-reset-tp4827089.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Spec - Columns Containing Rows Containing Columns
by Craig Johnson May 19, 2015

May 19, 2015

Hi, Spec has me tearing my hair out again. I'm using a composed layout with two columns in it. In the second column I'd like to place some rows which in turn contain columns. There does not seem to be any way to do this. Everthing that I try only renders one of the two main columns. Guidance would be spreciated. defaultSpec <spec: #default> ^SpecLayout composed newColumn: [ :tcol | tcol newRow:[:trow | trow add: #lblFolder ] height: 30. ]; newColumn: [ :tcol | tcol newRow:[:trow | trow newColumn: [ :tcol2 | tcol2 add: #ddlfolder]; newColumn: [ :tcol2 | tcol2 add: #txtFolder]. ] height: 30. ].
