Glamour accordion presentation
by Peter UhnÃ¡k July 3, 2017

July 3, 2017

Hi, I'm playing around with Glamour and accordion presentation, however there are couple things I'm struggling with. I have a simple presentation: ``` | browser data| data := { 'First' -> #(1 2 3). 'Second' -> #(a b c). 'Third' -> #(A B C). 'Fourth' -> #(! @ #'#'). }. browser := GLMTabulator new. browser column: #accordion. browser transmit to: #accordion; andShow: [ :a | a accordionArrangement. a title: 'Accordion'. data do: [ :pair | a fastList title: pair key; display: pair value ]. a list. ]. browser openOn: #(). ``` * Is it possible to tell the accordion to not take more space than is needed? E.g. after item 3, and after item $c there's lot of empty space. * Is it possible to close accordions upwards? I have added an empty list at the end to consume extra white space, but it is insufficient (see point above) and ugly. * Is it possible to control which accordions are opened/closed by default? * Is it possible to connect all the lists so only one item can be selected at any time? Currently I can select independently in the lists. * Is it possible to build the lists from the input data (=openOn: XXX)? I can fill the data, but if I am making multiple lists then I am lost. (I could use tree to fix most of the problems, but Accordion looks much nicer :)) Any pointers appreciated, Peter

Pharo6.0 for linux and PharoV60.sources location
by Andreas Sunardi July 3, 2017

July 3, 2017

Pardon me if this has been discussed before. I seem to recall somebody ran into this issue or related to this, but I don't remember what the solution was, if there was any. The linux Pharo 6 download package from Pharo web site has different VM directory structure than Pharo 5. The PharoV60.sources file is not located in the same directory as the VM binary. As a result, if user has image + changes files in another directory, Pharo always gives notification that the sources file is not found. This is not so with the Pharo 5. In most cases, it's just a notification, but in the past I've run into an error in debugging session when I tried to look into a method because of missing sources file. Can this be corrected or is it expected for the user to manage sources file where about? I'm hoping a correction or clarification would at least benefit new comers. -- Andreas

Custom Glamour browser for Dr. Geo scripting
by Hilaire July 2, 2017

July 2, 2017

Hi, I try to build a dedicated browser for user scripting on DrGeo. I am learning from the Deep into Pharo Glamour chapter, extending the given example. Regarding the method category pane, I need both instance and class side, so I write it like this: categoriesIn: constructor constructor list title: 'Methods'; display: [ :scriptClass | scriptClass organization categories]. constructor list title: 'Script data'; display: [ :scriptClass | scriptClass class organization categories] The browser is defined as: buildBrowser browser := GLMTabulator new. browser column: #scripts; column: #categories; column: #methods. browser transmit to: #scripts; andShow: [ :a | self scriptsIn: a ]. browser transmit from: #scripts; to: #categories; andShow: [ :a | self categoriesIn: a ]. browser transmit from: #scripts; from: #categories; to: #methods; andShow: [:a | self methodsIn: a ]. browser transmit from: #scripts; from: #categories; to: #methods; andShow: [:a | self classMethodsIn: a ]. browser transmit from: #scripts; toOutsidePort: #selectedScript. browser transmit from: #methods; toOutsidePort: #selectedMethod. ^ browser but something is missing to get the listed method right depending on the category is instance or class side. I don't how to do it. Any tips? Thanks Hilaire -- Dr. Geo http://drgeo.eu

PrimitiveFailed: primitive #createDirectory: in UnixStore failed
by Jacob Wagner July 2, 2017

July 2, 2017

Hi. I am trying to run pharo 6 in an Ubuntu 16 vm running XFCE desktop environment. I downloaded the 64 bit pharo zip and executed ./pharo The pharo GUI starts but immediately a debugger opens with the title's error message. After this, I cannot exit the VM normally by clicking the "x" in the upper right hand corner, i have to close the terminal because a similar error will popup if I try to close the window. How should I proceed? Not sure if I need to change permissions on files or whatever. ----- <zenchess(a)gmail.com> -- View this message in context: http://forum.world.st/PrimitiveFailed-primitive-createDirectory-in-UnixStor… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I think PharoJS can, and should do this much better: https://blockstack.org On Wed, Jun 28, 2017 at 11:21 PM, askoh <askoh(a)askoh.com> wrote: > Norbert: > > Great answer.

Re: [Pharo-users] Validate password with PBKDF2
by Erik Stel July 1, 2017

Hi Francis, You write: Pharo Smalltalk Users mailing list wrote > FIY > > UUID new asByteArray > > does not give a ByteArray because UUID is a subclass of ByteArray and > asByteArray returns self (Entering teacher mode) This actually means that "UUID new asByteArray" does answer a ByteArray. It will answer (as you mentioned correctly) itself. Since a UUID is a ByteArray it means it will answer a ByteArray (in contrary to your statement). To put it differently: The inheritance relation (UUID being a subclass of ByteArray) is a "IS-A" relation. So any UUID is a ByteArray. This means however the message "asByteArray" did not have to be send of course (it is already a ByteArray). I was not sure the class UUID was actually a subclass of ByteArray when writing my reply. Turns out it is.

FUEL documentation
by Juraj Kubelka July 1, 2017

July 1, 2017

(sorry, I have accidentally pressed send button) Hi, Is there any documentation about FUEL? I would like to understand in more detail what data are serialized, if I can somehow alter it (filter it) explicitly, and how can I handle errors on materialization. I was playing a bit with it and in some case, during the materialization, it complained that there is a missing class, but I was pretty sure that the class has nothing to do with the serialized objects. So, I will appreciate any documentation that helps to understand how I can analyze what is serialized and how to handle materialization errors. Thanks! Juraj
