I would be interested by having an example that I could use to rewrite the spec documentation: - would be good to have a kind of container relationships to be able to display multiple list - the model should not be too complex to explain. So if you have data and idea I'm all ears.

Thanks Maxim We are thinking with damien to extend pillar to have two columns (two lists, a list and figures, or two figures side by side) and like that I will be able to write a slide generator (that could output js format, beamer,....) and we could use pillarHub to edit and store slides :).

Re: [Pharo-users] Question on temporal variables in Workspace

yes that is an issue I have as well and it seems that it also continues in Pharo 4 Playground. But generally should not affect your code.

Apart from that the highlighting can be a bit flaky. The red should become blue once the variable is in use, it does do, but not reliably. Sven

Re: [Pharo-users] Question on temporal variables in Workspace

First of all thanks for all the responses. I should have checked the class comment first. I agree with Kilon, if I use a temporary variable in a workspace after doing the code if I inspect it the object is gone whereas doing it the way Kilon does the object is still there. Now why in my Pharo images Workspace variable (I suppose this is the correct term isn't it?) are in red and in Kilon's awesome tutorials are in blue? best regards Nacho ----- Nacho Smalltalker apprentice.

Implementation of book editor for PillarHub application

by Flayer

Hello everyone! My name is Maxim Skripnik, and I wish to tell you about my first project that deals with Pharo and Pillar world. To make a long story short, it's about extension of functional for web-application called "PillarHub" that is written fully on Pharo with Seaside's tools. In substance, today it's a editor and viewer for articles written on Pillar markup but I will add opportunity to compile complete books from them. Anyway, if you are interested in it, you may find full description * here <http://pillarhub.pharocloud.com/hub/MaximSkripnik/bookcompilerintro> *. There, on PillarHub, I will report on progress, so check for updates there. Feel free to comment and share your ideas with me, I would be very glad to see some. Thank you for your attention! -- View this message in context: http://forum.world.st/Implementation-of-book-editor-for-PillarHub-applicati… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Question on temporal variables in Workspace

by kilon alios

this is the class comment of Workspace : <<< A Workspace is a text area plus a lot of support for executable code. It is a great place to execute top-level commands to compute something useful, and it is a great place to develop bits of a program before those bits get put into class methods. To open a new workspace, execute: Workspace open A workspace can have its own variables, called "workspace variables", to hold intermediate results. For example, if you type into a workspace "x := 5" and do-it, then later you could type in "y := x * 2" and y would become 10. Additionally, in Morphic, a workspace can gain access to morphs that are on the screen. If acceptDroppedMorphss is turned on, then whenever a morph is dropped on the workspace, a variable will be created which references that morph. This functionality is toggled with the window-wide menu of a workspace. The instance variables of this class are: bindings - holds the workspace variables for this workspace acceptDroppedMorphss - whether dropped morphs should create new variables >>> Call me blind but I dont see anywhere mentioning local/temporary variables and how they work diffirently for wokspace compared to just regular workspace variables. Because thats exactly what we discuss here. "Once you get the hang of it, it is really cool and powerful." Indeed it get better and better, and I can see why pharo coders feel less need to rely on documentation compared to beginners like me and Nacho. The one thing that really annoy me with pharo is what I call "the happy Kangaroo" problem. That problem appears in some cases that one method depends on another which depends on the other etc etc that ends up a nasty spagettification .So trying to understand the code is like hunting down a happy Kangaroo. This is where class comments can be really helpful to help you understand something that you wont get easily from reading method source. Actually I think this workspace comment is quite good, I have no issues with it, it just does not answer the question of this thread which is ok. I dont care about perfection.
