Still, there is no > example of how to read JSON from a file in the whole document. These libraries (NeoCSV, NeoJSON, STON) were all written with only a dependency on a limited character stream API. It was a design decision not to depend on a File API, because at the time we were transitioning from the old FileStreams to FileSystem. And I disagree about the JSON introduction ;-) You might know it, but that is not the case for everyone. Like not everyone knows CSV, HTTP, ... But I do agree that sometimes I too would like a convenience method here or there ;-) > 2015-02-18 10:12 GMT+01:00 Sven Van Caekenberghe <sven(a)stfx.eu>: >> >>> On 18 Feb 2015, at 09:52, Andrea Ferretti <ferrettiandrea(a)gmail.com> wrote: >>> >>> Also, these tasks >>> often involve consuming data from various sources, such as CSV and >>> Json files.

GTTools: A bug and a suggestion

by Sean P. DeNigris

GT Tools are awesome!!! I'm molding some inspectors right now ;) Two things... Bug (I think): 1. Type in Playground: "1 printString" 2. Place cursor between "print" and "String" 3. PrintIt 4. Press enter to paste PrintIt as comment -> The comment appears at cursor position. I encountered this when I clicked at a random place in the selector to move the cursor to that line to PrintIt. At minimum, if nothing is selected, IMHO it should paste the comment after a word boundary, if not at the end of or line - not sure... Suggestion: now that Pharo 4.0 has horizontal scrolling, it would be interesting to scroll between the Miller Columns of the Playground that way (if a scrollable panel doesn't have focus) ----- Cheers, Sean -- View this message in context: http://forum.world.st/GTTools-A-bug-and-a-suggestion-tp4806061.html Sent from the Moose mailing list archive at Nabble.com.

GT Inspector Browse Icon

by Sean P. DeNigris

GT's browse icon does not match Pharo's (see the world menu), creating an inconsistent feel. In fact, I eventually clicked on the button only out of curiosity. Would it be possible to use whatever the underlying system uses (in this case "Smalltalk tools browser taskbarIcon")?

gtPresentation - #display:?

by Sean P. DeNigris

In experimenting with creating a custom inspector for my domain object, I came across the following intriguing method: Float>>#gtInspectorFloatIn: composite <gtInspectorPresentationOrder: 30> ^ composite table title: 'Float'; display: [ ... {'binary' -> self binaryLiteralString. 'significand' -> self significand. 'exponent' -> self exponent} ]; column: 'Key' evaluated: #key; column: 'Value' evaluated: #value; send: #value While it was easy enough to adapt this to my needs, I found the #display: and #send: sends quite strange. #display: seems like a strange API - like we're using an object designed to do something other than inspect objects; and I wasn't sure what exactly #send: did, my presentation seemed to function the same way with or without it... ----- Cheers, Sean -- View this message in context: http://forum.world.st/gtPresentation-display-tp4806066.html Sent from the Moose mailing list archive at Nabble.com.

FAMIXType>>incomingAccesses

by Damien Cassou

#flatCollect:. In my case, the variable 'attributes' is of type http://damiencassou.seasidehosting.st FAMIXType>>incomingAccesses ^ self privateState cacheAt: #incomingAccesses ifAbsentPut: [ attributes flatCollect: [ :each | each incomingAccesses ] ] Hi, in this method when the cache is empty, it is initialized with the result of FMMultivalueLink. When sending #flatCollect: to a FMMultiValueLink, the result is an OrderedCollection (because FMMultiValueLink>>#species returns OrderedCollection). This means that it is no more possible to update the list of incomingAccesses. Is that the desired behavior? In my case, this behavior triggers a bug. When the following method is FMMultiValueLink class>>on: element update: selector from: old to: new "refresh the other side of the relations to reflect change in value" old ~= new ifTrue: [ old notNil ifTrue: [ (old perform: selector) unsafeRemove: element ]. new notNil ifTrue: [ (new perform: selector) unsafeAdd: element ]]. ^ new executed while importing a mse, I get a DNU: This is because the (new perform: selector) expression returns an OrderedCollection that does not understand #unsafeAdd: (selector equals to #incomingAccesses).

moose and json

by Sebastian Heidbrink

Hi, I man ot sure if this is the right lists to ask such question please let me know if there is a better one. I am currently working my self through the moose book and Glamour chapter. I have a REST interface here that I would like to test and analyze via Moose. I have a json specification of all the apis available. So using a JSON parser in Pharo creates a Array/Dictionary based model representation. I wonder how you go from there? Do you implement the whole data model in Pharo to have a nice NeoJSON support? Is there already a package that genreates Smaltlak classes from Dictionaries? Is there a tool the create MSE files from JSON? Or are you just working with these Array/Dictionary structures? I currently just try to learn to use the Glamour Editor and try to represent the API in a useful way. Any hint, link or advice is very welcome Thanks Sebastian

Agile visualization book as an interactive grafoscopio document

by Offray Vladimir Luna Cárdenas

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 = 'código' 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: 'Código'. 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

tree presentation: displayblock and childrenblock

by Nicolai Hess

Why does a displayblock affect the arguments used for accessing the children of the nodes? The following code creates a TreePresentation from the current working Directory: browser := GLMTabulator new. browser column: #tree; column: #text. browser transmit to: #tree; andShow: [ :a | a tree title: 'FS'; "display: [ :item | item basename ];" children: [ :item | item isDirectory ifFalse: [ #() ] ifTrue: [ item children ] ] ]. browser openOn: FileSystem disk workingDirectory. As I don't want to see the FileReference printString, but the name of the File, the first thing I tried is a displayblock like the commented line above. But after this change the children block does not work anymore. The item it calls #isDirectory on, is not the FileSystem entry but the name returned by the display block. #format: instead of #display: works: browser := GLMTabulator new. browser column: #tree; column: #text. browser transmit to: #tree; andShow: [ :a | a tree title: 'FS'; format: [ :item | item basename ]; children: [ :item | item isDirectory ifFalse: [ #() ] ifTrue: [ item children ] ] ]. browser openOn: FileSystem disk workingDirectory May examples from GLMBasicExamples are using #display: , thats why I tried this first. What is the intention to use the display block for accessing the children? nicolai

Re: [Pharo-dev] TROSMTileProvider

Thierry, Onil, I rounded up my experiments with a 2nd commit on my experimental branch: === Name: Roassal2-SvenVanCaekenberghe.720 Author: SvenVanCaekenberghe Time: 5 February 2015, 3:40:43.211681 pm UUID: 121ffc22-4a30-4153-bef1-e019a92862bc Ancestors: Roassal2-SvenVanCaekenberghe.719 Experimental branch. Second version. Some more changes after discussing with Thierry @ Pharo Days and hours of experimenting Added TROSMTileProvider>>#cachedTileNamed: and #memoryCachedTileNamed: Rewrote/simplified TROSMShape>>#getTile: to no longer fork a 'get tile' process when the tile is cached in memory or on the file system Removed all hacks trying to optimize the number of times #signalUpdate was called - made no difference. Tried several logging approaches but that did not reveal anything special. The observed slowdown for tiles in the file cache but not the memory cache is still there, even though loading about 10 tiles takes less than 40 ms (see #testEmptyMemoryCacheParisLevel7) === Summary, it should be faster, but it is not. Forking and network downloading are gone, each of about 10 tiles takes less than 4 ms, the total observed slowdown is still about 1 to 2 seconds - with no extra #signalUpdate. I don't know why and I don't understand. I hope somebody can have a look, I feel that we can/should make this better still.

Using "onChangeOfPort: act:" to update data in a browser

by Offray Vladimir Luna Cárdenas

Hi, I'm reviewing my code, now that I have a better understanding of ports, transmissions and panes. I have nested browsers in my project: a tree that calls a generic node view, but when tagged it calls a custom node view which is a "sub-browser". For this I think that is better to use "onChangeOfPort: act:" instead of the "hacky" way of sending message to #nirvana or #nowhere ports. So, for example I have this minimal example to create a browser: http://ws.stfx.eu/CTGIBTCE70JL How can I change it to use "onChangeOfPort: act:" to update automatically the values in the dict instead of using "to: #values port: #nirvana;"? Thanks, Offray

transmissions and ports

by Sebastian Heidbrink

Hi! I am a little stuck. I would like to diplay two lists next to each other. List one displays entries and list two is empty. I would like to be able to select/multiselect entries in list one and make list two update and show these entries. When entries in list one are deselected, they shall be removed from list two again. Is a validator or a transmission/port solution the way to go here? Sebastian

Is Magritte and Glamour support already supposed to work in the current 5.1 image? My UI is empty. There is only a save and cancel button displayed. I also figured out that the example in the Moosebook seems to be outdated. Description was replaced by magritteDecription, wasn't it? Sebastian

Auto-updating the browser while changing tags without revisiting nodes on a tree

by Offray Vladimir Luna Cárdenas

Hi, I'm working on my project Grafoscopio, to provide a outliner/notebook like experience to write and visualize data. Details can be found on [1]. [1] http://mutabit.com/offray/static/blog/output/posts/grafoscopio-idea-and-ini… I want to create modal nodes by tagging them, so If I mark a node like code it can behave like a workspace and execute code. You can see a small demo of this feature on [2] [2] https://archive.org/details/grafoscopio-tags-alpha1.mp4 My code for tagging nodes is this: ==[a]============================================= UI>>addTagsTo: a Node "Tags the node passed as argument with a value from the collection of tags available" | selection | tagsAvailable isNil ifFalse: [ selection := UIManager default chooseFrom: tagsAvailable title: 'Elija una etiqueta'. aNode tagAs: (tagsAvailable at: selection) ] ifTrue: [self messageNoTagsAvailable]. browser update. ================================================= But I have three questions: i. How Can I update the nodes views/behaviour without revisiting them? The code in [a] is updating the node trees, but not the particular node views. ii. How can I made the code in a node tagged as "code" get executed? iii. Can I embed playgrounds instead of workspaces in a browser pane, with the possibility to explore objects and get more details about them? Thanks, Offray

Playing along with Moose :-/ + :-( + "-1"

by Offray Vladimir Luna Cárdenas

Hi, Today on [1] I read this: """ But, more important than technology is the humane face of Moose. Great ideas come from a state of play in which the current state of facts is taken apart and put together in a new way. That is why Moose is not a fixed thing, but a continuously moving target defined by what the community decides to play with. The only steady concern is to offer at every moment a set of engineered toys and the proper environment for a joyful and perhaps a successful play. All the rest is left for us, the players. """ [1] http://www.themoosebook.org/book/philosophy/research But I feel like playing along with my ideas in Moose. It doesn't matter if I change the way I ask, from time to time my questions get no answer and I revisit the bitter sweet experience of learning Moose. Several weeks ago I asked several questions about Moose. The "+1 consensus" was about asking simpler, so I did. Still I got no answer. I can understand that a direct question to a specific person gets no answer. Hell I'm pretty bad at addressing that questions when are directed to myself from time to time, but an open question for the whole community with only "+1" as the "collective" answer and then silence, even if I try to implement the suggestions for asking in another way can be very... not encouraging. Today I'm still wondering why or how I can't tell a tree to show the contents only if the node is selected, but I get error traces and lost of information by selecting an empty part of the tree to which my custom browser doesn't know how to respond to. Today I'm feeling there is no "us" in "players" for Moose, specially if you're a newbie... only "you" the "single player". :-/ Offray

VerveineJ download

by Andrea Caracciolo

Hi, Is it still possible to download verveineJ for free ? I tried: svn checkout svn://scm.gforge.inria.fr/svn/verveinej But it now seems to require special permissions. Creating an account at InriaForge does not seem to solve the problem. Can you help me? P.S: the moose book ( http://www.themoosebook.org/book/externals/import-export/external/verveineJ) points to a broken link (http://www.moosetechnology.org/tools/verveinej) Cheers, Andrea Caracciolo _____________________________ Software Composition Group University of Bern

How do I store the rhs of an assignation

by Damien Cassou

Hi, I'm working on analyzing Python source-code with Moose. In Python, one can write: import re as regex and this means "declare a local variable named 'regex' and put a reference to the PyModule named 're' inside". How can I model that in the mse file please?
