Adding a new menu entry in GTDebugger

Hi! I am doing some experiment to get object-centric debugging. How can I add a new menu entry in this menu: Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Editable text field inside Roassal/Trachel Canvas
by Peter Uhnák 25 Feb '15

25 Feb '15

Hi, is it possible to embed (any) editable text field inside Roassal? I managed to add the editor morph inside Trachel's athens canvas, however there is no way I can access it... my guess is that TRMorph takes all the events, or drawing the morph on the canvas destroys something. I tried it with PluggableTextFieldMorph (shows the border of the edit field, but no text), and TxTextEditorMorph (shows text). Is there any way around this? Adding the morph inside AthensWrapMorph works correctly, so my guess is that TRMorph must be doing something... perhaps I should also add it as a submorph of TRMorph somehow? My testing code follows: ------------------------------------------------ "opening the canvas and adding custom shape" trCanvas := TRCanvas new. text := SBEditableTextShape new. trCanvas addShape: text. trCanvas open. ------------------------------------------------ ------------------------------------------------ "content of SBEditableTextShape - same as the attachement" 'From Pharo4.0 of 18 March 2013 [Latest update: #40470] on 1 February 2015 at 10:13:04.069249 pm'! TRShape subclass: #SBEditableTextShape instanceVariableNames: 'txMorph txModel wrapMorph textMorph' classVariableNames: '' poolDictionaries: '' category: '_Sandbox'! !SBEditableTextShape methodsFor: 'drawing' stamp: 'PeterUhnak 2/1/2015 22:10'! drawOn: aCanvas " aCanvas fullDrawMorph: textMorph." aCanvas fullDrawMorph: txMorph.! ! !SBEditableTextShape methodsFor: 'initialization' stamp: 'PeterUhnak 2/1/2015 22:07'! initialize | string | super initialize. string := 'quick brown fox jumps over the lazy dog'. txModel := string asTxModel. txMorph := TxTextEditorMorph text: txModel. txMorph extent: 150 @ 50. textMorph := PluggableTextFieldMorph new. textMorph extent: 150 @ 50. textMorph setText: string. textMorph ghostText: 'ghost text'.! ! ------------------------------------------------ Any help is appreciated, Peter

Regression in GT?
by Alexandre Bergel 25 Feb '15

25 Feb '15

Hi! Yesterday I have downloaded the last version of Moose, and I was surprised to see what I feel are functionality regression. - If I open a Playground, and I type 3 times the key “[“ then I end up with "[ [ [ ] ] ]” whereas I would expect to have “[[[]]]”. Since I often use the playground to edit pillar code, this is not cool. - When I use spotter, and started to type something, when the spotter window is refreshed, the selection goes at the first item, which is not great if I started to move down the selection bar and I get a refresh. Am I the only one to see this? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Relative border width
by Yuriy Tymchuk 25 Feb '15

25 Feb '15

Hi, at the moment border width is absolute (or constant), so if scale the picture border width remains the same. Is it possible to have a border width that scales? I.e. if you have a box of size 20 and border of size 2 then when box is zoomed to 10px the border will have the width of 1px? Uko

Evaluating scripts within Pillar
by Alexandre Bergel 24 Feb '15

24 Feb '15

Hi! I am now digging into Pillar. My goal is to be able to insert Roassal script and having it executed. Scripts provided within [[[ ]]] may be evaluated using the variable ‘eval=true’. Here is an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: '100 factorial = [[[eval=true stream nextPutAll: 100 factorial asString ]]]'; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ‘stream’ is a hardcoded variable name which represents the stream on which you have to write your result. What you write in stream is pillar-friendly. This means you can write something like: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: '100 factorial = [[[eval=true stream nextPutAll: ''""'', 100 factorial asString, ''""'' ]]]'; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I have tried to insert some Roassal visualization, and it works pretty well. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: ' !!Example of a factorial 50 factorial = [[[eval=true stream nextPutAll: ''""'', 100 factorial asString, ''""''. ]]] !!Some Roassal visualizations Here is a small Mondrian example [[[eval=true b := RTMondrian new. b nodes: (1 to: 100). b layout grid. b build. aView := b view. RTHTML5Exporter new insert: aView named: ''Roassal test'' inPillarStream: stream ]]] Another example with Grapher this time: [[[eval=true b := RTGrapher new. b extent: 300 @ 200. ds := RTStackedDataSet new. ds interaction popupText. ds barShape width: 10. ds points: #(4 5 1 -2 5 6). b add: ds. "b axisX noLabel; noTick. " b build. RTHTML5Exporter new insert: b view named: ''A Graph'' inPillarStream: stream ]]] '; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Pillar is very well done! Congrats to the authors! Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Glamour-Presentations-YuriyTymchuk.171, Glamour-Morphic-Renderer-YuriyTymchuk.310
by Yuriy Tymchuk 23 Feb '15

23 Feb '15

DiffMorph has a concept of contextClass that it uses to highlight method sources that are diffed. I’ve added a support of this feature to the glamour presentation and renderer. Please let me know if it is ok and if I can contribute like this or there is a more formal process. Uko

Glamour-Morphic-Renderer-YuriyTymchuk.309
by Yuriy Tymchuk 23 Feb '15

I’ve removed explicit white color form the renderer, as on the dark theme it wasn’t working well. Let me know if this is fine, because I thought that maybe a color from theme should be specified, but I didn’t find any colors in other renderers. Uko

PetitParser performance
by Usman Bhatti 22 Feb '15

22 Feb '15

Hi, Since the work on the integration of PPContext in PetitParser, there is significant performance degradation. I have already mentioned that on simple grammar the factor is about 2. But on complex grammar (for example, our proprietary parser for 4D language ), we have seen that degradation is goes well beyond this factor. So, for example, for 800K lines that we parse in under 10 minutes without PPContext work, with the latest version it goes beyond 2h. I have not been able to reproduce my case on simple grammars. May be we can have some benchmarks using open source parsers and large code bases (e.g. PP Java Parser on JHotDraw or ArgoUML). Currently, I circumvent this issue by using PP v1.51 but I can provide relevant feedback and run benches on any improvements. regards. Usman

Problem with downloading and running Moose 5.0
by Manfred Kröhnert 19 Feb '15

19 Feb '15

Hi, I tried to download and use Moose 5.0 on a 10.6 OS X machine but hit some issues on the way. So far I did not try anything related to Moose 5.1. My first attempt was to download from here: http://moosetechnology.org/#install However, all Moose links point to non existent files redirecting me to a 'Not Found' HTML page. Then I followed the link to the Pharo VM download (http://pharo.org/download), downloaded the OS X package by clicking on the OS X 'button', and executed the Gofer statement from the website. Everything downloaded and installed fine. But when I tried to run any of the Roassal demos a debugger window opened complaining about some cairo method which could not be found. I know that there is ongoing work in the Pharo VM towards a Cairo based backend, but unfortunately the Pharo VM I downloaded does not include it. It would be nice if you could provide me with any hints on how to get a working Moose/Roassal image. Also let me know if there is a another/better list where I should ask such questions. Many thanks, Manfred
