BaselineOf vs ConfigurationOf

by Peter UhnÃ¡k

Hi, can anybody tell me the difference between BaselineOfX and ConfigurationOfX? The only thing I've gathered is that BaselineOf is used for Git projects, while ConfigurationOf for Monticello projects; but usage-wise they seem identical. Thanks, Peter

What UI direction now (or in the near future)?

by Petr Fischer

Hello! Suppose, that I need to write simple UI app + write my own UI list component (some special behaviour, canât use default list UI component from Pharo) + I need perfect keyboard support (shortcuts, tab navigation + navigation by cursor keys in some windows), which also means, that I need perfect UI component âfocusâ supportâ¦ Another priority: I do not want to learn things (in exhaustive detail) that expire in 2 years. Current status: I like Smalltalk (Pharo!), know basics of Morphic and I noticed some future as Athens and Bloc. I am trying to get out from âclosedâ app development and Apple âclosedâ technologies as ObjC/Swift/Cocoa and want to be little more productive and platform independent. Simple, snappy, attractive and smooth UI is the key for me/users. And nowâ¦ which direction: 1) old Morphic (simple powerful work with old Morphs etc.) 2) Morphic + Athens drawing (maybe I donât understand the connection) 3) Bloc Sub-questions: A) Is Bloc (complete Morphic rewrite, sigh) âone man showâ? What about future, support, long-term issues? Look at Marina CMS framework, even used for Pharo website, but not maintained now... B) Is Bloc prepared with Retina displays in mind (perfect smooth fonts and graphics, scaling, more detailed images for retina etc.)? C) Is current keyboard + UI component focus support perfect or pain in... Isnât a âbad timeâ for this decision (Pharo) now? Thanks very much for any brief hint, Petr Fischer

Then we need some chunked format, to avoid copying large blocks of memory. Stephan

Evaluating scripts within Pillar

by Alexandre Bergel

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 âeval=trueâ. Here is an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= PRHTMLWriter defaultConfigurations anyOne inputString: '100 factorial = [[[eval=true stream nextPutAll: 100 factorial asString ]]]'; outputFile: 'myFirstPillarExport.html' asFileReference; export -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= âstreamâ 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 ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

by phil＠highoctane.be

This one may come handy. http://smalltalkhub.com/#!/~philippeback/HOExtras/packages/Printf Works like a C printf. Coupled with 'Blah {1} and {2}' format: { '5.2d' printf: aNumber. '%5s' printf: aString } it can go a long way. Phil
