Recipe: Reading a file

Problem

You want to read in a text file to the Squeak environment.

Solution

>
You create an instance of a FileStream on the file.

file := FileStream fileNamed: 'test.txt'.

Then you can do things like...

Process a line at a time:

[file atEnd] whileFalse: [ line := file nextLine. "Process the line" ]

Or just read the whole file into a String:

string := file upToEnd.

Discussion

Look at the Stream protocol, particularily in Stream and
PositionableStream.

If you just need to read the file, open FileList and it will open in a
Workspace.
