Re: [Pharo-users] Beginner of smalltalk 80 - first graphic windows and GUI -2

by kilon alios

Hello Hans My opinion is that you waste your time trying to find a smalltalk 80 just because you were used to it. Its like me returning back to GWBASIC which is the first programming language I learned to use back in 1988. Why use something so old that cant take advantage of new technology and new software ? It will only make suffer and limit you in many diffirent ways. Pharo is a modern implementation of smalltalk it does not try to stick to the past it prefers to embrace the future of smalltalk. Morphic is what Pharo has inherited from Squeak and is by far the most dominant and most mature GUI API of Pharo. New kids in the block graphic wise is Spec , Athens and Roassal.The only common amongst those three is that they are no GUI APIs but they are graphic libraries Spec is wrapper above GUI APIs currently it wraps only Morphic and makes it easier to create complex GUIs. Unlike Morphic however has a steep learning curve but pharoers prefer it because it is easier to manage. Spec documentation is in a dedicate site (Just google "spec pharo" and you will find it) and in Pharo For The Enterprise book. Athens is also similarly to spec a wrapper above vector graphics libraries , currently it wraps the cairo libraries and can mix with Morphic . Athens docs are in Pharo For The Enterprise book plus there is a athens interactive tutorial in smalltalkhub Roassal is part of the moose tools a collection of tools for the visualisation and organisation of code. Roassal is also a wrapper above graphic libraries , it wraps both Morphic and Athens and it has also some GUI classes . Roassal documentation is in Deep Into Pharo and I think it has a chapter in Pharo for the Enterprise. Agains all these doc are easily revealed with a simple google search. GUI wise I will say that Morphic is still the undisputed king and Spec becomes slowly very popular as a way to manage Morphic easily. There is also a new and only Morphic replacement in the works that is called Bloc but I have not tested to provide information about it. So both Morphic and Spec are viable options. Obviously Morphic is more documented because of Squeak but Spec is more actively developed right now in Pharo. Whatever you pick any problems you have you ask here and you get your questions answered and you can also ask at stackoverflow if you have already an account there. There are also other GUI and Graphic libraries inside Pharo and outside Pharo , Pharo like squeak comes with several FFIs that allows you to use external C / C++ library (C++ libraries will have to be wrapped as C libraries) which this alone give you access to pretty much every GUI libraries that popular languages use. JNIPORT is Smalltalk library that allow Pharo to use Java libraries so you can also use Swing. I am also working on a way to allow Pharo to use Python libraries , I was partly successful into creating QT GUIs via pyQT which is the python wrappers for QT GUI API . QT is probably the most powerful GUI library out and so much more than that. So in reality you have like a ton of options , everything comes with its advantages and disadvantages but for now Morphic and Spec should be enough for your needs.

Beginner of smalltalk 80 - first graphic windows and GUI -2

by Hans Schueren

Hello , here is Hans , The Byte Surfer , the smalltalk code is from books of year 1992 and 1993 1988 and 1987. I have a lot of books around the world . ALL of the Topic SMALLTALK 80. Only 80 !!! Because i am a absolute beginner and want to learn smalltalk 80. I realized that thing have changed. for example GUI programming Mosttimes there is a optional library needed for creation. There is a optional IDE i know , for those things. No Matter ! I dont know anything about the NEW TOOLS and Replacements in actual Smalltalk Engineering like PHARO. Please tell me what i have to learn. What is GUI IDE in Pharo. Do i have to learn Morpic. What else for Window and Buttons design ? The Pharo ( and actual squeak ) have very much weight for a beginner. Is it right , that all " NEW STUFF " is decribed in the two manuals : Pharo by Example + Deep into Pharo. Or is there any other actual description about "Up to date programming Pharo" ???? Sincerely Your Friend Hans The Byte Surfer PS.

Re: [Pharo-users] Beginner of smalltalk 80 - first graphic windows and GUI - need help

Hello Hans, the standard way to build GUIs using Pharo is to use Spec. I suggest you have a look at the documentation of Spec online, do the tutorial and then you can start experimenting. The easiest way to see the Spec documentation is here: https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… On Nov 26, 2014, at 10:16 AM, Hans Schueren <werbung(a)hans-schueren.de> wrote: > To whom it may concern , > > > may i ask for some help about standard graphic routines ? > > As a beginner i just have learned all the first level SYNTAX of smalltalk 80. > > Now , you can imagine , i am interested in writing little GUI windows and graphics for > > placing some text in the right positions. > > > Theese are the statements i have studied from my material. > > > Does anybody know why the statements not work? > > Are there any "replacements" for the syntax that i posted here as example ? > > Have a nice day > > > > > HERE ARE THE EXAMPLES : > > > > > | window | > window := ScheduledWindow new. > window component: 'Hello World' asComposedText. > window open > > > > > | window | > window := ScheduledWindow new. > window label: 'Fenster ohne Inhalt'. > window minimumSize: 200 @ 100; maximumSize: 400 @ 300. > window open > > > > > displayOn: aGraphicsContext > 1 to: 10 do: > [:i| > aGraphicsContext translation printString > asComposedText displayOn: aGraphicsContext. > aGraphicsContext translateBy: 15 @ 15] > > > > > Greetings > > > Hans > The Byte Surfer > > ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Re: [Pharo-users] Citizen example for manipulating a bibtex file

by Sven Van Caekenberghe

Hi Offray, I think I better understand what you are doing now, and how you are using STON. What I think might help you (in your use case), is to add two options: 1 - to STONWriter #keepNewlines that converts any newline inside Strings to a newline as specified by #newline: instead of encoding it as unprintable 2 - to STONReader #convertNewlines that converts any newline inside Strings to a newline as specified by #newline: instead of keeping it as is Now, 2 is already there, except that any newline read is kept as it is, while I think it would be better to convert CR, LF and CRLF to just one (to be specified). Similarly, 1 would convert CR, LF and CRLF to a single one (to be specified). Without these conversions, mixups between different line end conventions could easily happen. I think it is too much work to do this in your own models. If you think this would help, I'll put this on my todo.

Re: [Pharo-users] Beginner of smalltalk 80 - first graphic windows and GUI - need help

by ClÃ©ment Bera

Hello, I don't really know how to answer. Are your examples really from smalltalk-80 ? Were they running on the Xerox-D microcoded machine ? Because I don't think there are anymore smalltalk-80 available right now, nor machine that can run it. There's a smalltalk-78 running on javascript on the web but that's a bit different. Here you're on the Pharo mailing list, which is a smalltalk which has evolved during 35 years starting from smalltalk-80, so it's quite different from smalltalk-80 right now (for example, closures and exceptions were added, support for modern computers too). To use window as you are doing something like that works: | window | window := StandardWindow new. window title: 'Hello World' . window open However nowadays people use frameworks to build UIs in Pharo, not such APIs. So it depends what you want to do. 2014-11-26 14:16 GMT+01:00 Hans Schueren <werbung(a)hans-schueren.de>: > To whom it may concern , > > > may i ask for some help about standard graphic routines ? > > As a beginner i just have learned all the first level SYNTAX of smalltalk > 80. > > Now , you can imagine , i am interested in writing little GUI windows and > graphics for > > placing some text in the right positions. > > > Theese are the statements i have studied from my material. > > > Does anybody know why the statements not work? > > Are there any "replacements" for the syntax that i posted here as example ? > > Have a nice day > > > > > HERE ARE THE EXAMPLES : > > > > > | window | > window := ScheduledWindow new. > window component: 'Hello World' asComposedText. > window open > > > > > | window | > window := ScheduledWindow new. > window label: 'Fenster ohne Inhalt'. > window minimumSize: 200 @ 100; maximumSize: 400 @ 300. > window open > > > > > displayOn: aGraphicsContext > 1 to: 10 do: > [:i| > aGraphicsContext translation printString > asComposedText displayOn: aGraphicsContext. > aGraphicsContext translateBy: 15 @ 15] > > > > > Greetings > > > Hans > The Byte Surfer > >

Beginner of smalltalk 80 - first graphic windows and GUI - need help

by Hans Schueren

To whom it may concern , may i ask for some help about standard graphic routines ? As a beginner i just have learned all the first level SYNTAX of smalltalk 80. Now , you can imagine , i am interested in writing little GUI windows and graphics for placing some text in the right positions. Theese are the statements i have studied from my material. Does anybody know why the statements not work? Are there any "replacements" for the syntax that i posted here as example ? Have a nice day HERE ARE THE EXAMPLES : | window | window := ScheduledWindow new. window component: 'Hello World' asComposedText. window open | window | window := ScheduledWindow new. window label: 'Fenster ohne Inhalt'. window minimumSize: 200 @ 100; maximumSize: 400 @ 300. window open displayOn: aGraphicsContext 1 to: 10 do: [:i| aGraphicsContext translation printString asComposedText displayOn: aGraphicsContext. aGraphicsContext translateBy: 15 @ 15] Greetings Hans The Byte Surfer

Thanks Peter and Alexandre for your quick answers and interest, First, there is now a blog post with your solution and the lessons learned on our workshop about the dynamics of it and some improvements to be done to agile visualizations here: http://mutabit.com/offray/static/blog/output/posts/medios-en-colombia.html Is in Spanish, because is directed towards the local community, but some Spanish speaking devs at Pharo/Roassal could also take advantage of it and comment the ideas feedback them to the development process.

Awesome is easy to install and quick to use, and you get beautiful images! 2. Where the data comes from? When I explain that most of it comes from code inside pharo (relationships on the source code) or from things like buildEdgesFromObjects: (1 to: 20) from: [ :n | n // 3 ] they hit the first wall. So, what is needed is to preserve the awesomeness of complex beautiful visualization while making a bridge that takes the newbies from where they are towards that visualizations. Take for example the graph chapter[a] and imagine that after all the current, complex and beauty visuals that work as a panoramic view of what can be done (in a small gallery, for example, with source code linked to it), we start from the basics and away from the specifics software analysis. Saying something like (linking your basics to the graphs chapter): =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Graphs can represent a lot of relationships. The previous gallery is made using the internal relationships in the agile visualization platform software, but we can take other relationship. For example: "Processing a small TSV table" tab := RTTabTable new input: 'id origin relation destiny 1 Orange is a Fruit 2 Apple is a Fruit 3 Apple has color Red 4 Rice is a Cereal'. and lets build a graph small graph of this data: [...] =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- [a] https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/Graph/0204-… Woud be nice to have an easy way to add tabular data, may be using GT support for table like interfaces (as I suggested in the blog post) so the recollection of data to make a visualization and the visualization code can be linked together more fluidly. In this way we can keep a balance between awesomeness and easiness. >> - Would be nice to have tools for all Roassal visualizations like export as svg.

The idea of putting it on GT seems the proper way to do it. The current way of using external tools to take screenshots or the mysterious way that uses the internal tool of Pharo or code messages are not friendly. A explicit button/menu with explicit options to store the images or a notification about where they are saved are the way to go for newbies. >> I would like to post the working example on the meetup page, so if any can tell me why the example is broken or how to solve it, would be nice. > > How can we help?

Re: [Pharo-users] Named edges and nodes in a Roassal graph

by Alexandre Bergel

Hi Offray, The chapter about Roassal contains several examples on how to name nodes: https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/Roassal/010… To label the nodes, the simplest way is to use @ RTLabelled. (However, you need first to add the element in the view before doing @ RTLabelled). This works pretty well. Here is your code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "Definimo los elementos, que denominamos simplemente e1, e2, etc, con su color y su tamaÃ±o" e1 := (RTEllipse new color: (Color blue alpha: 0.4); size: 20) elementOn: 'hello'. e2 := (RTEllipse new color: (Color red alpha: 0.4); size: 20) elementOn: 'Bonjour'. e3 := (RTEllipse new color: (Color yellow alpha: 0.4); size: 20) elementOn: 'Gutten Tag'. e4 := (RTEllipse new color: (Color green alpha: 0.4); size: 20) elementOn: 'BuenGiorno'. "Adicionamos los elementos a la vista" vista add: e1; add: e2; add: e3; add: e4. "Decimos que los elementos antes definidos se podrÃ¡n arrastrar" e1 @ RTDraggable @ RTLabelled. e2 @ RTDraggable @ RTLabelled. e3 @ RTDraggable @ RTLabelled. e4 @ RTDraggable @ RTLabelled. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= You have something like that: For the edges, you can simply use @RTLabelled on an edge. Consider: -=-=-=-=-=-=-=-=-=-=-=-= line1 := line edgeFrom: e1 to: e2. line2 := line edgeFrom: e2 to: e1. line3 := line edgeFrom: e1 to: e2. line4 := line edgeFrom: e2 to: e2. line5 := line edgeFrom: e3 to: e4. vista add: line1. vista add: line2. vista add: line3. vista add: line4. vista add: line5. line1 @ RTLabelled. line2 @ RTLabelled. line3 @ RTLabelled. line4 @ RTLabelled. line5 @ RTLabelled. -=-=-=-=-=-=-=-=-=-=-=-= You can particularize the edge label with something like: line1 @ (RTLabelled new text: 'my edge').
