Spotter: Browse Impementors?
by Sean P. DeNigris Feb. 10, 2015

Feb. 10, 2015

Maybe I'm missing something obvious, but if I zero in on a message name in spotter, can I open a browser on all implementors, or only browse one specific method? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spotter-Browse-Impementors-tp4805013.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Externally signalling pharo VM for shutdown
by Esteban A. Maringolo Feb. 10, 2015

Feb. 10, 2015

Is there a way I can externally signal a running pharo-vm in order to request a shutdown equivalent to clicking on the close icon? I'd like to externally manage the start/stop of a Pharo image, but because the image can be used during development, I'd like to provide the user with a confirmation dialog instead of simply killing the process. Regards! Esteban A. Maringolo

Agile visualization book as an interactive grafoscopio document
by Offray Vladimir Luna CÃ¡rdenas Feb. 10, 2015

Feb. 10, 2015

Hi all, This mail will have two parts, a small first one where I share my advances and little context on the project and the second one, with details where I made specific questions regarding concepts and code and how to make progress. I hope to be fluid and proper balanced and interesting enough to get feedback soon. Context ======= I have made a small video at [1] showing my progress on Grafoscopio[2], a tool for the creation of interactive notebooks for open/citizen/garage science and research (for a better view I recommend to see the video in full screen mode). As you can see, I have a complete outline of the Agile Visualization book stored as a single "ston document" [3], that can be exported to pandoc's markdown [4] and from there to LaTeX, pdf, html, doc, etc. It can contain special tagged nodes and the view and behaviour of them change accordingly to the tag. In the video a node tagged as code is showed as an interactive playground where you can execute an explore the objects deeper. My problem is that this kind of special nodes are not saved, as happens with default nodes and the reason is that the special view (which is a sub-browser) is not wired properly to the rest of the browser and that's why I get a nill value after revisiting the code node in the video. [1] https://archive.org/details/gfcp-alpha-code-exec-but-non-saving.mp4 [2] http://mutabit.com/offray/static/blog/output/posts/grafoscopio-idea-and-ini… [3] http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Ag… [4] http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Ag… Details ======= The logic of what I'm doing is something like this: i. When a node in tree at the left is selected, it shows the contents of the selected tree. ii. If something changes in the node content at the right, the changes are automatically updated. iii. If a node is tagged in a special way, a custom browser is called. The code that select which sub-browser to show for a particular tagged node is something like this: ==[a]============================== UI>>buildBrowserNamed: aName "Main method for building the interface for trees and its nodes. The name of the browser corresponds to the name of the file where tree is stored (or is named 'draft.ston' by default)" "... snip" (browser transmit) from: #tree port: #selection; to: #nodeBody; when: [:selection | selection notNil]; andShow: [ :a :node | self bodyIn: a for: node. self body2ForCodeIn: a for: node. self bodyForTransmediaIn: a for: node ]. "... snip" "Creating a self updatable body pane" (browser transmit) from: #tree port: #selection; to: #nodeBody; when: [:selection | selection notNil]; andShow: [ :a :node | self bodyIn: a for: node. self body2ForCodeIn: a for: node. self bodyForTransmediaIn: a for: node ]. (browser transmit ) from: #tree port: #selection; from: #nodeBody port: #text; when: [:node :text | text notNil & node notNil]; to: #nodeBody port: #neverland; transformed: [:node :text | node body: text asString]. (browser transmit) from: #tree; to: #nodeHeader; andShow: [ :h | self headerOn: h ]. (browser transmit ) from: #tree port: #selection; from: #nodeHeader port: #text; to: #nodeHeader port: #neverland1; when: [:node :text | text notNil & node notNil]; transformed: [:node :text | node header: text asString] =================================== The last part of the code is responsible for updating the tree contents automatically with The "body2ForCodeIn: for:" [b] is the responsible for showing the playground by calling a custom browser that is called "panelAsCodeFor:"[c]. Here is their code: ==[b]============================== UI>> body2ForCodeIn: constructor for: aNode "Shows the body of a selected node as executable code." aNode tags = 'cÃ³digo' ifFalse: [ ^self ] ifTrue: [constructor custom: (self panelAsCodeFor: aNode)]. =================================== ==[c]============================== panelAsCodeFor: aNode "Shows an interactive playground for Smalltalk code in a node body" browser := GLMTabulator new. browser title: 'CÃ³digo'. browser column: #code. browser transmit to: #code; transformed: [ GTPlayPage new content: aNode body ]; andShow: [ :a | a custom: GTPlayground new ]. browser sendToOutside: #nodeBody from: #code -> #text. ^ browser. =================================== So, wiring by "sendToOutside: from:" is not working and I don't know how to tell my code browser to autosave its contents as part of the node body where they belong. Any help with this is appreciated. Cheers, Offray

Changes file size
by Torsten Bergmann Feb. 10, 2015

>I always found it strange what effect loading Glorp had on an image, blowing it up. Looks like it is really an effect of the Glorp code. Maybe because it was initially exported from VW and then imported into Squeak/Pharo. I always thought slow loading is because of this or the long license texts in the classes. At least I had similar issues when I loaded the "Glorp-EstebanMaringolo.92" from October 2014. I was not able to browse diffs, etc. when I wanted to clean up. Then I commited "Glorp-TorstenBergmann.93" without real changes and things started to stabilize. At least I was able to browse the diffs afterwards and could refactor a little bit with Glorp-TorstenBergmann.94. Bye T.

How to send messages to an object.
by nacho Feb. 7, 2015

Feb. 7, 2015

Hi, Suppose I do: Morph new openInWorld and then: EllipseMorph new openInWorld without referencing them to a variable. How do I access those objects? Since the only thing I know is that is a "a Morph(428605440)" and a "an EllipseMorph(448004096)" If I want to Morph(428605440) addMorph: EllipseMorph(448004096) How do I achieve this? Because they are both object living in the system but I can not reference them..... Thanks in advance Nacho ----- Nacho Smalltalker apprentice.
