[Pharo-project] Misc. newbie questions
by Gerry Weaver Feb. 27, 2012

Feb. 27, 2012

Hello All, Firstly, let me say that I am enjoying Pharo very much at this point. I wish I would have found the time to look at this a long time ago. I have a few misc. newbie questions.Â 1. VisualWorks - I am doing a lot of thinking about projects that I could use Smalltalk on. I have a consulting project coming up that might be a good candidate, but I'm sure I would be required to use a commercial Smalltalk version for it. I guess it may be odd to ask about VisualWorks on this list, but I'm not really looking for a comparison to Pharo. What I'm interested in is your opinion of the product. I would like to know if any of you would consider using it on a project. I would appreciate anything y'all could share in the form of experiences good or bad. I am trying to get my hands on it, but Cincom's mail server (windoze) is having issues. I am also having some trouble getting pricing out of them. Anyway, I would like to get your take on the Cincom products. 2. There appear to be some tool choices in the Pharo image. I would like to be able to create a class and it's methods in an editor in one go. I like being able to see all of the class code at once. Is there a way to do this? Â I just want to be able to type it all in and accept (evaluate?) all at once. 3. I've seen some discussion about images and image sizes. What is the current state of this. Is it possible to strip an image down to just the required components for an application (ie; no world menu, etc.). I would like to be able to run an image that would bring my gui application up filling the image window such that it looks a close as possible to a conventional gui application. 4. I have been reading about something called "Opentalk". It is a way for images to be able to comminucate with each other over the network. I've also seen something callesd "rST" that appears to do a similar thing. In addition, I notice that someone has done some FFI bindings for zeromq. What would y'all recommend as the best option to achieve something like this in Pharo? 5. I'm trying to figure out exactly what the Pharo gui toolkit provides in the way of widgets. Is there a widget gallery type thing somewhere that shows all of them? I know I can play with them in the image, but it would be nice to see a list of what is there with a brief description. 6. I know Pharo doesn't currently support OS threads in an image, but I'm wondering about the FFI. Is it possible to call a foreign function in a separate OS thread or asynchronously in Pharo? Disclaimer: I'm not asking for any how to type answers here. I can do the reading and experimentation myself. I just want to know if these things are possible and where to start looking for a solution.Â Thanks, Gerry

[Pharo-project] selectionForDoitAsStream smells
by Nicolas Cellier Feb. 27, 2012

Feb. 27, 2012

Compare this which is like old squeak selectionAsStream SmalltalkEditor>>selectionForDoitAsStream ^ ReadWriteStream on: self string from: self startIndex to: self stopIndex - 1 and this which has been changed conforming to Cuis TextEditor>>selectionAsStream "Answer a ReadStream on the text in the paragraph that is currently selected." ^ReadStream on: (self string copyFrom: self startIndex to: self stopIndex - 1) (or self selection asString readStream) The two differ. The former stream position starts at editor startIndex - 1, while the later stream position starts at 0. The stream position is used by the Compiler/Parser for notifying the SmalltalkEditor (or TextMorph) requestor. Now look at SmalltalkEditor>>notify: aString at: anInteger in: aStream "The compilation of text failed. The syntax error is noted as the argument, aString. Insert it in the text at starting character position anInteger." | pos | pos := self selectionInterval notEmpty ifTrue: [self startIndex + anInteger - 1 ] ifFalse: [anInteger]. self insertAndSelect: aString at: (pos max: 1) You see that it adds (startIndex - 1) to the error message insertion position which is a Cuis change. (The old ParagraphEditor did not). When #notify:at:in: is used for evaluating #selectionAsStream, all is OK, the (startIndex - 1) is added only once. But when it is used with #selectionForDoitAsStream, the offset is counted twice (because already in the stream location passed in anInteger parameter). I guess the hack #selectionForDoitAsStream that undo the Cuis clean-up has been added because some other part of Parser/Encoder/Compiler is messing with the requestor selection (like highlighting some part of the source for user interaction in case of ambiguity). Tthis is not a valid workaround. In Squeak, I did revert the Cuis clean-up just to keep some simple compatibility with ParagraphEditor, but Pharo does not care about that, so it should apply full simplification. I suggest removing #selectionForDoitAsStream, and replace senders with #selectionAsStream. Then if there are some other feature broken we'll fix'em. OK? Nicolas

The debugger opens really slowly. I cannot access ss3 repositoriesâ¦. So there is definitively something strange. Stf

But you need to take care that there is right know no way to get the menu other then right-click. Command-Click which is normally the same is not the same in this case...
