I'm reading "Smalltalk Best Practice Patterns". The pattern
"Indented Control Flow" recommends putting each keyword on a
separated line, indented with a tab. I like that for long messages,
but this one example annoys me.
array
at: 5
put: #abc
Earlier the author explains the how conserving vertical space
increases readability. This example contradicts that advice.
Also, it just seem so verbose compared to the Java equivalent of
"array[5] = "abc";".
Do experienced Smalltalkers really like this formatting for short
messages like at:put: or is the following preferred?
array at:5 put: #abc
I normally use the separate-line version, just because I find it
easier to follow the same formatting nearly everywhere. I remember
someone (Beck?) giving similar reasoning somewhere about using "each"
as a loop variable, or "i" as a loop index - nothing to think about,
and you can recognize what's going on anywhere at a glance.
I do occasionally "break" this rule, though. For example, to:do: comes
to mind - I'll usually write
1 to: 15 do:
[:i |
"..."
"..."]
instead of
1
to: 15
do:
[:i |
"..."
"..."]
Hope this helps,
Ben Schroeder
