ST 4U 288: Using Files in VA Smalltalk

September 26, 2012 14:07:15.354

Today's Smalltalk 4 You looks at file i/o in VA Smalltalk - starting with the basics. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

file io.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at file handling in VA Smalltalk. The simplest way to get started is with FileStream - which doesn't look like it exists. That's because it's an alias for CfsFileStream:

Files

Working with files in VA Smalltalk is fairly straightforward. You send messages to the abstract superclass (CfsFileStream), and, depending on the API, you get back the concrete subclass. You then work with that using standard stream protocol:


"Open a file read only"
stream := FileStream open: 'abt.ini' oflag: ORDONLY.
text := stream upToEnd.
stream close.
^text


"open a file, simpler API
stream := FileStream read: 'abt.ini'.
text := stream upToEnd.
stream close.
^text

"open for writing"
stream := FileStream write: 'test.txt'.
stream nextPutAll: 'This is a test'; cr.
stream close.

Go ahead and try those out (possibly changing the names depending on what files exist in for working directory).

Smalltalk Training

September 26, 2012 8:09:16.000

David Buck is setting up another online Smalltalk training course:

I've been asked if I can deliver an "Intro to VisualWorks" webcast course sometime in October. This course would be delivered over the Internet so students wouldn't need to travel to take the course. If you are interested or know of anyone who's interested, drop me an e-mail at david@simberon.com.

ST 4U 286: Interesting Collection Methods

September 21, 2012 10:20:01.137

Today's Smalltalk 4 You looks at some of the more interesting methods in the collection hierarchy. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Collections.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at some of the more useful methods in the Collection class hierarchy, and use some examples to illustrate. We're using VA Smalltal, so fire that up and look at class collection:

Collection

Select the ANSI-API category, and have a look at the methods - you can count on the ones here being implemented (and implemented this way) across all the major Smalltalks. Some of the methods here are "new" - in the sense that the various vendors have only added them to their distributions in the last few years. Today we'll take a look at some of these methods:


coll1 := #(1 2 3 4 5).
coll2 := #(4 5 6 7 8).
coll3 := #(1 1 2 3 3 4 4 5).

coll1 anySatisfy: [:each | each < 10]. true
coll1 allSatisfy: [:each | each < 3]. false
coll1 noneSatisfy: [:each | each > 10]. true

coll1 intersection: coll2. Set(4 5 )

coll2 occurrencesOf: 2 0 

coll3 sorted: [:a : b | b <= a] (5 4 4 3 3 2 1 1)

The results of executing each line of code is after each line (using Display from the workspace menu). If you don't follow why, go ahead and experiment with the examples, and debug through them.
