I've been mostly programming in Perl for more than a decade, and for a long
time (possibly longer) have adopted a 4-whitespace indentation increment. This
worked pretty well in Perl, and I rarely ran out of indentation. I've also
successfully used 4-whitespace increments in C, in bash and a little in
Python.
Now, I've been studying Ruby in the past few years, and one of the pieces of
advice I got was that it is customary to use 2-whitespace increments in Ruby
code instead of 4, because indentation is used to a large number of levels in
Ruby. Now, I haven't converted to 2-whitespace increments in Ruby yet, but I
did notice that when I'm writing Ruby code, I tend to run out of indentation
with 4-ws-increments, and find my code to be too indented to the right.
My question is: can anyone explain why are 4-ws-increments good enough in
Perl, C, and other languages, but they tend to be insufficient in Ruby code?
Why are more indentation levels required in Ruby? Or are the lines themselves
are required to be longer?
