New Introductory Tutorial
by EuanM 26 Aug '16

26 Aug '16

I've created Yet Another Smalltalk First Steps tutorial. This is intended as one of a series. It is designed to be cross-platform across Squeak 5 Pharo 4 Seaside 3.1 Cuis Dolphin 6 If you have experience running any of these systems on Windows, Linux or MacOS, please check to see if I have the instructions correct for your chosen pairing of Smalltalk and OS platform. (As you'll see when you look, I do not have detailed instructions for aspects of MacOS). The document is at: http://smalltalkinsmallsteps.blogspot.co.uk/2015/11/get-smalltalk-up-and-ru… (It's intended to move to a different blog after this review process). I feel the need to do this as cross-Smalltalks tutorial because of findings and 4 charts I've placed at: http://smalltalkinsmallsteps.blogspot.co.uk/2015/11/mindshare-of-smalltalk-… Essentially, Smalltalk mindshare and use is incredibly tiny, compared to other languages in the same space. (We all know this, but seeing it represented graphically has a more visceral effect, IMO) Aggregating interest in all the Smalltalks still does not bring more than a tiny proportion of the interest in, and use of, Ruby. In turn, Ruby is (quite understandably) small in comparison to JavaScript. Comparing interest in any specific Smalltalk is, predictably, smaller than the aggregate interest in Smalltalk. Our community seems determined to split itself into smaller and smaller sub-communities. I think we do ourselves a disservice this way. My initial contribution will be to try to provide some explicitly pan-Smalltalk beginners' tutorials, like this one. Cheers, and happy Smalltalking, EuanM

Need a local tutor for Squeak
by Joseph Alotta 14 May '16

14 May '16

I need a local person to help me with Squeak Smalltalk. I like in the Western suburbs of Chicago, in Downers Grove. I want someone to show me all the things I am missing and to help me use the tools more effectively. I am thinking we could meet at a coffee shop once a week for an hour. I would pay for each lesson, $70.

conceptual design help
by Joseph Alotta 29 Apr '16

29 Apr '16

Greetings, I am writing a program to consolidate all my personal finances for tax time next year. (This is not a school project.) There are transaction files from several banks and credit card companies. Each has a similar format, CSV, but they vary in many ways, order of items, extra notes, pipe delimited or tabs, etc. I want to read them and load them into a collection of transaction objects. 1. Should I have a FileReader object? 2. Should it have subclasses like FileReaderAmericanExpress, FileReaderJPMorgan ? 3. Or should it have different methods like loadAmericanExpresFile, loadJPMorganFile ? 4. Is a Collection of Transaction objects, the structure that you would load the files into? The rest of the project would be to do data checking on the files, to make sure there are no duplicates or missing dates. Then write reports that I can give to my accountant. I would appreciate some design help? Sincerely, Joe.

go to the end of a loop
by Joseph Alotta 26 Apr '16

26 Apr '16

Greetings, I have this code: ****** read "read the category file into the dictionary the first item is the category, the rest of the line are payees office expense|home depot|staples|costco groceries|natures best|jewel|trader joes|fresh thyme " | f line | f := FileStream oldFileNamed: myfile. [(line := f nextLine) notNil] whileTrue: [ | array cat payees | array := line findTokens: $| escapedBy: Character tab . cat := array first. payees := array reject: [ :i | i = cat ]. "rest of the line" payees do: [ :p | mydict at: (p withBlanksCondensed) put: (cat withBlanksCondensed)]. ]. f close. ********* I am getting some blank lines in the data file. Lines with just a Character cr. I was wondering how to handle that. In other languages, there is a break for the loop, to go to the end. I can do: (line size < 2) ifTrue: [ f nextLine.]. But that would interfere with the notNil idiom at the end of the file. So where do I put this. Is there a common way to jump to the end? Sincerely, Joe.

debugging by using a global variable?
by Joseph Alotta 21 Apr '16

21 Apr '16

Greetings, My code has some complex parts and I think it would be good to pull parts of it out and practice with it in a workspace window. For example, I have an Array of Transaction objects, that is a instance variable. It is mostly populated from reading a file. What would be the best method to extract this array? Assign it to a global variable? Sincerely, Joe.
