If you missed our discussion with Marcus, Opal allowed constructs like that until week ago.

You are right there is such a code. And it's really strange how it compiled earlier:) Thanks 2014-09-06 11:42 GMT+03:00 Esteban Lorenzano <estebanlm(a)gmail.com>: > well, this is weird :) > the error you have is usually because you have something like this: > > myMethod: aParameter > â¦ > aParameter := something. > â¦ > > (same can happen with blocks). > > you cannot assign a parameterâ¦ and compiler protests if you try. > but I wander how you could introduce the problem the first time.

Re: [Pharo-users] Syntax Error: Cannot store into

by Esteban Lorenzano

well, this is weird :) the error you have is usually because you have something like this: myMethod: aParameter â¦ aParameter := something. â¦ (same can happen with blocks). you cannot assign a parameterâ¦ and compiler protests if you try. but I wander how you could introduce the problem the first time. Compiler should deny that kind of construction. Anyway, your fix is to change that :) Esteban On 06 Sep 2014, at 10:39, Mark Rizun <mrizun(a)gmail.com> wrote: > Package of my project RewriteTool. > Here it is: http://smalltalkhub.com/#!/~MarkRizun/RewriteTool/packages/RewriteTool > > > 2014-09-06 11:33 GMT+03:00 Esteban Lorenzano <estebanlm(a)gmail.com>: > which package? > > > On 06 Sep 2014, at 10:28, Mark Rizun <mrizun(a)gmail.com> wrote: > > > Hi everyone! > > > > When loading a package via Monticello, while compiling methods it gives an > > error: > > Syntax Error: Cannot store into and then a method. > > What does it mean? > > > > Best, > > Mark > > > > > > > > -- > > View this message in context: http://forum.world.st/Syntax-Error-Cannot-store-into-tp4776675.html > > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > > > > >

Syntax Error: Cannot store into

by Mark Rizun

Hi everyone! When loading a package via Monticello, while compiling methods it gives an error: Syntax Error: Cannot store into and then a method. What does it mean?

Re: [Pharo-users] not a smalltalk!

by Esteban Lorenzano

no smalltalk around is âsmalltalkâ, technically they are all dialects and Pharo is just one dialect more. smalltalk-80 itself does not exist sinceâ¦ well, smalltalk-80 :) so no, your code would not be directly portable to other smalltalks (with the possible exception of gemstone).

Re: [Pharo-users] Moose browsers: Updating an object value from a text pane and from an emergent window

by Offray Vladimir Luna CÃ¡rdenas

Hi Doru an community, In almost a week from now I will write an small revision article about this prototyping exercise on Moose/Glamour/Pharo, for structured writing. My ideal would be to write it inside this prototype, but for that I need to be able to edit and store the changes on the tree and its node contents. Hopefully it won't take too much, even for a newbie like me. Even if is not possible, and I need to go back to Leo Editor (http://leoeditor.com/) for reporting and writing the article, this exercise has been really valuable. This are my issues so far: Auto-updating objects from the browser is working but I'm having problems to integrate this with my code. To follow better what is happening just: 1. Follow the installation notes on: http://wiki.hackbo.co/doku.php/herramientas:grafoscopio:en:install 2. Run this code: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- | text mainTree | mainTree := UbakyeNode new. mainTree becomeDefaultTree. text := (mainTree children at: 1) body. GLMCompositePresentation new wrapper with: [ :wrapper | wrapper show: [ :a | a text ]. wrapper transmit fromOutsidePort: #text; toOutsidePort: #portIDoNotCareAbout; transformed: [ :textComingFromThePresentation | text := textComingFromThePresentation ] ]; openOn: text. (mainTree children at: 1) body: text =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- If I comment the last line, I can explore the Browser Tree and see how #text updates automatically, but if I leave it uncommented I can explore the mainTree and see that is not updating. Also I tried to put the transmit parameters in the build browser transmit parameter, just here: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- UbakyeBrowser>>buildBrowser "(... snipped code)" (browser transmit) to: #body; from: #tree; andShow: [ :a | self bodyOn: a]. "(...snipped code)" =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- replacing "to:", "from:" and "andShow:" for "fromOutsidePort:", "toOutsidePort:" and "transformed:" as shown in your example, but then the current selection in the tree got disconnected from the body pane. I would mind to have a explicit button or keyboard shortcut to take what is currently on a text pane and send it all to a particular node for updating, if this is the quickest workaround. So, How can I made this? Also, Doru showed to me a way to invoke inspector on the current selected node. Suppose that I want to have an emergent window to edit the node header and some tags on it. Is this possible?

Re: [Pharo-users] Hello ...

by kilon alios

Just started to play with Racket a few moments ago http://racket-lang.org/ There so many great languages out there and tools, really. GUI wise the future of Pharo is at least cleaning up Morphic. So it can only get better. Spec also looks like it has a promising future in Pharo. I was thinking implementing my own GUI using the Blender Game Engine (making it possible to use 3d guis) and I was even flirting the idea of porting QT to Pharo via my project Ephestos. So things are moving forward and there is nothing stoping that.
