Ruby Source Code Layout
- 1 min- Use UTF-8 as the Source file encoding.
- Use to spaces per indentation level (aka soft tabs). No hard tabs.
# bad - four spaces
def some_method
do_something
end
# good
def some_method
do_something
end
- Don’t use ; to separate statements and expressions. As a corollary—use one expression per line.
# bad
puts 'foobar'; # superflous semicolon
puts 'foo'; puts 'bar' # two expressions on the same line
# good
puts 'foobar'
puts 'foo'
puts 'bar'
puts 'foo', 'bar' # this applies to puts in particular
- Prefer a single-line format for class definitions with no body.
# bad
class FooErro < StandError
end
# okish
class FooError < StandardError; end
# good
FooError = Class.new(StandardError)
- No space inside range literals.
# bad
1 .. 3
'a' ... 'z'
# good
1..3
'a'...'z'
- Don’t use several empty lines in a row
# bad - It has two empty lines.
some_method
some_method
# good
some_method
some_method
