Actually, you can do (1->2 -> 3) if you have multiple levels :) But clearly I will introduce a real data structure here. I just wanted to quickly hack it and have something where I can do #head and #tail easily, and keep a simple way to write it :) Ben On Oct 12, 2013, at 3:04 PM, Sean P.

Indeed, it was just a first try to have something to build a reflection on :-) Changing the name is always easier than implementing something new (and it's also easier to have the community involved at this level).

I agree with Camillo in that I think it would be better to use specific selectors, e.g. selectedItem:withParents: as it better reveals the intention. Just my 2 cents ...

Re: [Pharo-users] Simple Spec Examples

by Camillo Bruni

Would it be possible to change the name of the selector? tree selectedItem: (1 -> 11) for me that implies that the tree contains an actual item (1 -> 11). What you want is maybe, #selectedPath: or #selectedItem:1 withParents:{11} My general rule is: Each time you have to use an association or a point you do something wrong.. It is hard to guess what this association should mean, so either make a domain object to describe what you encode in the association or use specific selectors that say what the arguments mean.

Thanks for the example :) Indeed, the documentation is a bit outdated since Spec is still improving a lot, a changing a bit in its API.

Yes we need to stabilize it and get a real document.

Spec Lists - setting the selection

by btc＠openinworld.com

I found it hard to find documentation on Spec beyond [1],[2],[3], some of which seem to have changed some syntax since they were written. I've been piecing things together to work out how to set the selected item with the simplest example I could. Even though it turns out pretty simple, I thought I'd share in case it was useful for others that haven't dipped their toes into Spec yet. ComposableModel subclass: #TestSpec instanceVariableNames: 'list text' classVariableNames: '' poolDictionaries: '' category: 'BTCPlay' TestSpec >> initializeWidgets self instantiateModels: #( #list #ListModel ). TestSpec >> getList ^list TestSpec class >> mySpecLayout <spec:#default> ^ SpecLayout composed add:#getList ; yourself. Then from Workspace x := (TestSpec new openWithSpec ; yourself). x getList items: { 1 . 2 . 3 . 4}. x getList setSelectedItem: 2. cheers -ben [1] hal.inria.fr/hal-00759030/PDF/Spec-IWST12-Final.pdfâ [2] https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… [3] http://hal.inria.fr/docs/00/70/80/67/PDF/SpecTechReport.pdf
