Fwd: [squeak-dev] I'm stepping down as WebTeam Leader Mars 31

by Lukas Renggli

Anybody interested to step up for a new (or revised) web-site for squeak.org based on Seaside (and maybe Pier)? > In the back of my mind (well maybe more in the foreground than that) I > wondered why no one from the Seaside community had stepped up and it > occurred to me that Janko stepping up might spur one of them to also do > so. That has yet to happen. See: http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-March/126523.ht… http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-March/126535.ht… Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Re: Questions about Seaside/Pier

by Lukas Renggli

Hi Damien, > I have some questions: > > - why do you use random numbers in PRMailLink>>urlEntry? The class comment of PRMailLink says it all: "I am an external link pointing to a mail address. I encode my URL to prevent spam bots collecting the address." > - why is it not possible to use #mailto: in WAAnchorTag in Seaside > anymore (it's deprecacted)? It is useless, isn't it? The attribute and the body of the tag require different encoding anyway and this is only possible when using a propre URL object. Lukas -- Lukas Renggli http://www.lukas-renggli.ch

strange behavior for edit design?

by Tudor Girba

Hi, Here is what I did: - I downloaded the latest Seaside.app - Started Pier in the browser - Edit Design - Save This results in a page that shows the pages referenced in the Environment as missing. The problem seems to be that the relative links in the Environment are now solved differently. Before, they were solved relative to the Environment, but now they seem to be solved relative to the page from where I invoke Edit Design. I figured this out because if you sy Edit Design from the Environment page, the links are resolved correctly :). So, is this the intended behavior? If it is, it means that we have to specify the Environment with absolute links. Cheers, Doru -- www.tudorgirba.com www.tudorgirba.com/blog "Sometimes the best solution is not the best solution."

Json visitor and MAFileModel

by Ronaldo Ferraz

Hello-- Newbie here. :-) I'm writing a Json visitor for a project and I'd like to stream MAFileModel on it but I'm at a loss about how to proceed. For most simple descriptions, streaming the value is just a matter of rendering the value according to the description using the normal visitor pattern. However, MAFileModel is a full-blown class and doesn't have a corresponding description to guide the process. What would be the most interesting path here: add the required descriptions to the classes or just go ahead and stream the attributes? It seems to me that the second options make the Json visitor to tightly coupled to the MAFileModel class. On the other hand, adding the descriptions may not be that interesting because it would mean changing a Magritte base class. Any suggestions? Thanks. :-) -- Ronaldo Ferraz http://log.reflectivesurface.com

[Pier] PRMeta questions/clarifications - Is it transposable to MADescriptions ?

by cdrick

Hi The purpose or PRMeta is to add meta information to structure... "additional fields to any structure (sort of a replacement of Pier-Form)" . Is it this kind of extension that could help resize picture for instance (we add 2 Number that describe height and weight). I don't see really well how to use them. Can you provide me a simple example ? What is the way to use these meta variables in computation ? Also, would PRMeta extensions to PRStructure could be added to MADescription ? I want to make a description wich is basically a single option description, except that I'd like to extend the description with a symetric matrix that held comparison similarity numbers. For instance, let's consider an attribute weatherCondition, it's options are: (excellent, good, bad, extreme). Let say, I have the following comparison matrix for the attribute weatherCondition: excellent good bad extreme excellent 1 0.8 0.1 0 good 1 0.2 0 bad 1 0.7 extreme 1 so that: similarityBetween: 'good' and: 'bad' returns 0.2 I'd like to attach this matrix to the description, and was thinkink an extension like meta could do it. It will allow me to edit the similarity matrix too (sort of edit meta like in pier). If you see any obvious alternative to do what I want, please tell me, but I find this could be nicey done with Magritte. Thanks Cédrick

Why OrdeeredCollection>>removeAll

by Mathieu Suen

Hi, When I look at the code of OrderedCollection>>removeAll from de Squeak- Web image I see: removeAll "remove all elements quickly" self become: OrderedCollection new It seem to me that is not a fast way of removing all element of the collection. I would rather do: removeAll self setCollection: (Array new: self size) I do not see the #removeAll method in other image and by looking at the sender it seem that is aida who use it. Mth

MATableComponent - using condition on cells

by cdrick

Hi I'd like to be able to put condition on cells of my table. I want them to be Number (float between 0 and 1 or integer between 0 and 100). So I changed the method buildDescriptionTable in MATableComponent (a copy of it) buildDescriptionTable ^ self dataTable collect: [ :row :col :each | self description reference copy "(-> return a MAStringDescription)" accessor: MANullAccessor new; label: row asString , '/' , col asString; propertyAt: #row put: row; propertyAt: #column put: col; yourself ] becomes: buildDescriptionTable ^ self dataTable collect: [ :row :col :each | MANumberDescription new accessor: (MABlockAccessor read: [ :model | (model memento cache at: (self description) ) at: row at: col ] write: [ :model :object | self halt. (model memento cache at: (self description) )at: row at: col put: object]); min: 0 max: 1; label: row asString , '/' , col asString; readonly: (col < row); propertyAt: #row put: row; propertyAt: #column put: col; yourself ]. I think that instead of a NullAccessor and write:using: and readUsing: which I removed, I can have a real accessor that can do the job. but this doesn't really work :) I'm sure I messed something with the memento (all table value are the same now), so if you see something wrong in what I did, please tell me. Thanks, Cédrick

Accessor for class inst var

by cdrick

Hi, Still for my descriptor (attribute). I defined a similarity matrix in the class side. I've never used Magritte to edit class inst var, so out of curiosity, what accessor would you use ? I've use a Block Accessor. (MABlockAccessor read: [ :model | model class matrix] write: [ :model :object | model class matrix: aMatrix]); Is it ok to edit class side inst var ? What would you use ? Also, I was doing a matrix description, but I saw MATableModel and MATableComponent... it seems to be a "matrix", isnt'it ? Thanks Cédrick

by cdrick

Hi, My import through SIXX is OK. I can load it but when I try to login, the squeak image crash. Does someone have experienced the same problem or have an idea of the problem origin ? only updating the image causes trouble too. Thanks Cédrick
