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.
