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

From Charter to Grapher
by Hernán Morales Durand 19 Feb '15

19 Feb '15

How would be ported this code using RTCharterBuilder | b | b := RTCharterBuilder new. b extent: 500 @ 200. b points: keys. b stackX. b allY: [ : each | aBag occurrencesOf: each ]. b histogramWithBarTitle: #yourself. b axisY. b newAxisConfiguration plain. b axisXTitled: 'MyTitle'. b axisX. b build. ^ b using RTGrapher? Because some methods are missing (#points: #stackX, etc) in the latest version of Roassal2. Hernán

undeclared warnings
by Andrei Chis 19 Feb '15

19 Feb '15

Hi, Now in the moose build there are a lot of undeclared warnings: https://ci.inria.fr/moose/job/moose-5.1/117/console I will start fixing them once jenkins starts working again. Most of them come because of the order in which packages are loaded (a test package is loaded before the code that it tests). Cheers, Andrei

This looks great! What do you use to handle the interaction?
