Now that my image is working properly again and the fires have been put out, I wanted to introduce myself a bit better... My name is David Boeren. I first learned Smalltalk back in college many years ago, we used Smalltalk V in an object oriented programming class I took which was first-half Smalltalk, second-half C++. This would be about 1992 I think? In recent years I've mainly been using Java, with occasional Python dabblings. I remember installing Squeak once or twice over the years, but to be honest it felt a bit clunky, perhaps this was just an early primitive version or whatever. Recently, I've been getting the itch to try out some different languages. I was kind of looking at Scala or Clojure, one co-worker suggested Erlang, and so forth. But after doing a brief review I ended up coming back to Smalltalk which even after all these years still stands right up with the cutting edge I think. Sure, there are a few things that I think would be a little different if it were designed today like tuple support or whatever, but it feels like the right choice for something I'm going to use mainly for "fun" projects and the interactive environment is awesome. One thing I wanted to ask about is the status of getting Pharo running on iOS (or at least iPad). I found some old posts but nothing much within the last couple of years. I know there were app store policy issues in the past but I think that Apple has opened things up a bit since then, you can now get Pythonista in the app store, or Codea. Is there still an obstacle or is it just something that hasn't been gotten around to yet? I'd love to get it running on my iPad Mini and be able to transmit code back and forth between there and my laptop to work on it wherever I'm at. Second, I'm running into an oddity and I'm not sure what I'm doing wrong or whether this is a bug of some sort, this has to do with trying to replace unicode characters in a string which seems like it should be a straightforward operation. Here is my code: "Fetch the raw JSON data from dtdb.co" response := 'http://dtdb.co/api/cards/' asUrl retrieveContents asString. "Clean up the data a bit to make it a little more regular" response := response copyReplaceAll: 'null' with: '""'. response := response copyReplaceAll: '\u2022' with: ','. response := response copyReplaceAll: '\u009e' with: 'e'. Basically I'm just pulling some JSON data and then doing a few string replacements to make the data suit my needs. The first one works. The second one works. Since the third one ALSO uses a \uXXXX code I would expect it to work too, but it does not - the accented characters are still there. To get a bit more visibility into this, I copied the CopyReplaceAll code from SequenceableCollection into a scratch class method and adding some Transcript output: copyReplaceIn: aString All: oldSubCollection with: newCollection "Answer a copy of the receiver in which all occurrences of oldSubCollection have been replaced by newCollection " | startSearch currentIndex endIndex | Transcript show: 'start' ; cr. startSearch := 1. [(currentIndex := aString indexOfSubCollection: oldSubCollection startingAt: startSearch) > 0] whileTrue: [ Transcript show: 'Found at index ' ; show: currentIndex ; cr. endIndex := currentIndex + oldSubCollection size - 1. aString := aString copyReplaceFrom: currentIndex to: endIndex with: newCollection. startSearch := currentIndex + newCollection size]. Transcript show: 'done' ; cr. ^ aString A minimal test seemed to work: HelloWorld copyReplaceIn: 'R\u00e9my Lapointe' All: '\u00e9' with: 'e'. start Found at index 2 done Testing this with the real data worked too: HelloWorld copyReplaceIn: ('http://dtdb.co/api/cards/' asUrl retrieveContents asString) All: '\u00e9' with: 'e'. start Found at index 22379 Found at index 22500 done However, when I went back to using the regular copyReplaceAll:With: method it does not work and I'm not sure why. When it executes this: aString indexOfSubCollection: oldSubCollection startingAt: startSearch The value comes back as 0 even though it's the same data from 'http://dtdb.co/api/cards/' asUrl retrieveContents asString (I added a "self halt" to be able to step into the method and view the variable values), and I'm not sure what the difference is. There shouldn't be a limit on the size of the collection, should there? The whole thing is around 116k which is big but not ridiculously so. It is however big enough that the debugger can't show the whole value, or at least I haven't found a way to do so. And last, is there a good video tutorial for the Pharo beginner on how to use the various browsers, debugger, tools, etc... that come with Pharo? I would like to start learning more about the best ways to use these in my development processes. I'm also having a lot of trouble finding the correct classes and message for what I want to do, searching online w/ Google often seem to turn up outdated information (or for a different smalltalk flavor) and it can take a while to figure out the correct way to do things. Is there a good central reference for the APIs somewhere? I know that you can search in the browser but I usually don't know the name to search for. It would be good to have a handy reference detailing how to do all the commonplace stuff.
