Smalltalk interactive tutorial in good English
 
|
Hi
I've written a sort of interactive tutorial based on (old) Stephane's screencasts about Smalltalk syntax. It's called PrStef ;). To load it:
Gofer new squeaksource: 'PrStef'; package: 'PrStef'; load. and to run it: PrStef go. I'm looking for English-speaking people to check that the texts are written in a correct English before I make a screencast on it. Thank you !
Cheers, Laurent _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Hi Laurent! This is really cool. I am preparing welcome workspaces for the next dev image. I already wrote the one which is here:
http://code.google.com/p/pharo/wiki/GettingStartedWorkspaces which I converted in a workspace. I used ShoutWorkspace for that because you have colors and is nicer :) If you want to see what I did, download the package ImageForDevelopers-pharo-MarianoMartinezPeck.212 from http://www.squeaksource.com/ImageForDevelopers See the class methods of DEVImageWorkspaces class I will add this tutorial also to the getting started part. What do you think ?

Totally stupid question: how can I change the text inside a ShoutWorkspace once it's opened ?
If you want :) Laurent

I love it!
especially the PrStef previous :) and the expression with the PrStef next inside It was a great idea. > Gofer new > squeaksource: 'PrStef'; > package: 'PrStef'; > load.

Maybe my answer is more stupid than your question ;) I think I don't understand. If you change an opened Workspace, you are just changed that object. It is not persisted any more. In the example I gave you (DEVImageWorkspaces openWelcomeWorkspace for example) when I write the text, I write it inside the method in the class browser. I happens to me a lot of times that I start to modify it in the opened workspace instead of the code...so then I need to copy paste :) Cheers Mariano

hey this is really neat!
I can offer you some corrections or perhaps suggestions for better phrasing. just my native 2p if it helps. As a general comment, i know it would be more work, if you could get some emphasis e.g bold, italics it would really make the expressions and names of classes or methods stand out. ---Welcome--- I suppose you have called me to learn Smalltalk. --> You must want me to help you learn Smalltalk! ---Doing vs printing--- You've just executed a Smalltalk instruction --> You've just executed a Smalltalk expression ---Doing vs printing 2--- It's a Do It which print the result --> It's a Do It which prints the result ---basic types numbers--- you know how to execute Smalltalk code --> you now know how to execute Smalltalk code ---basic types characters--- A Character can be instanciated --> A Character can be instantiated --basic types string--- Use single quotes to create a String instance --> Use single quotes to create a String. ---basic types dynamic array--- Dynamic Array are created at execution time: --> Dynamic Arrays are created at execution time: ---unary messages--- Unary messages have the following form: anObject aMethod name --> anObject aMethodName --keyword messages-- The message is between:and: sent to Number object --> The message is between:and: sent to the Number 4 ---message syntax: execution order--- Between similar messages, expressions are executed from left to right --> Between messages of similar precedence, expressions are executed from left to right ---parentheses--- Use parentheses to change order --> Use parentheses to change order of evaluation ---mathematical precedence--- A message does not know mathematical precedence. Simplicity has a price :) --> (rephrase ?) Traditional precedence rules from mathematics do not follow in Smalltalk. The simplicity has a price ;) It might surprise you that precedence rules you know from mathematics do not apply here. This has a price as you can see... ---conditionals--- Conditionals are just message sent to Boolean objects --> Conditionals are just messages sent to Boolean objects ---loops--- Loops are messages send to collections, high-level iterators --> Loops are messages sent to collections, high-level iterators ---iterators--- Here we want to print all the numbers of the Transcript (a console) --> Here we want to print all the numbers on the Transcript (a console) ---() vs []--- --> I know what you are trying to articulate here, but this page doesn't really work since your 'annotation' is not syntactic and therefore your learning style breaks. pehaps have a think about this slide cheers Mike _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Michael: I will put some welcome workspaces in the next PharoDev. I also have the same problem with the English.
I would also like to put italics and bold, but I have no idea how to do it. If you want to check what I wrote, would be really cool as I plan to do the next dev image during the weekend. If you are willing to do it: Gofer new squeaksource: 'ImageForDevelopers'; package: 'ImageForDevelopers-pharo'; load. And look for the class side methods of DEVImageWorkspaces !!! Thanks for any feedback.

np, i will have a look this weekend. I don't know exactly how to
create emphasis, but Text and TextStream look likely. Look at class references and you will get some examples. Also senders of asText (152!), and surrounding protocol. I don't know how you integrate these into the workspace though. I'm sure there is an example somewhere. cheers, Mike 2010/1/15 Mariano Martinez Peck <[hidden email]>: > Michael: I will put some welcome workspaces in the next PharoDev.

To display each lesson I use PluggableTextMorph#setText: (You can take a look at LessonView#open and LessonView#showLesson)
I haven't found a such method in Workspace. On squeaksource I have committed a version which use PluggableShoutMorph, so now I have syntax highlighting.

Did you mean something like (Workspace new contents: ('red text' asText addAttribute: (TextColor color: Color green)); embeddedInMorphicWindowLabeled: 'Welcome to Pharo') position: 100@100 ; width: 200; height: 500; openInWorld ...? Stan |
