Hi Norbert,
Hi,
I'm asking myself if there is any common sense about how to indent the code in smalltalk/squeak.
Most of the time I see something like
statement do: [ :parameter | otherStatement selector: [ mostinnerstatement ] ].
or
statement do: [ :parameter | otherStatement ].
Kent Beck's "Smalltalk Best Practice Patterns" has a good section on this. He presents ten simple patterns to drive the formatting of Smalltalk code.
The book is a bit older now - it dates from 1997 - but might not be too hard to find. I think our local library system (here in Columbus, OH) even had a copy.
Beck's Indented Control Flow pattern says,
Put zero or one argument messages on the same lines as their receiver. For messages with two or more keywords put each keyword/argument pair on its own line, indented one tab.
So, you would say
limit := myList size.
or
larger := firstCount max: secondCount.
but
inRange := amount between: low and: high.
He also has patterns that describe how to format conditionals, blocks, etc. The rest of the book is good too - it has advice about other parts of Smalltalk usage.
As others have said, of course the most important thing is to pick a style that works well and use it consistently. I like Beck's style, but as you have seen, there are other good ones in use.
