Question

如何在Ruby中注释多行？

  ask by Mohit Jain translate from so

Answer 1

#!/usr/bin/env ruby

=begin
Every body mentioned this way
to have multiline comments.

The =begin and =end must be at the beginning of the line or
it will be a syntax error.
=end

puts "Hello world!"

<<-DOC
Also, you could create a docstring.
which...
DOC

puts "Hello world!"

"..is kinda ugly and creates
a String instance, but I know one guy
with a Smalltalk background, who
does this."

puts "Hello world!"

##
# most
# people
# do
# this


__END__

But all forgot there is another option.
Only at the end of a file, of course.

• This is how it looks (via screenshot) - otherwise it's hard to interpret how the above comments will look.

  (这就是它的外观（通过屏幕截图）-否则很难解释以上注释的外观。)
