This question taught me how I can use an if statement without an else. I need the exact same thing, but for mutiple lines of code instead of one line of code.
I have tried this, but this does not seem to work:
def self.foo(a)
{
#mutiple lines of code
}if a == true
end
This is very basic ruby syntax. All the ruby control structures can be used in inline way, or in multi-line/block way, closed with end keyword.
def self.foo(a)
if a == true
# mutiple lines of code
end
end
For more informations about syntax and ruby best practices, you can refer to : this ruby style guide
If you really want to do this, use parenteses, not curly braces:
def self.foo(a)
(
puts 'a'
puts 'b'
) if a == true
end
Although I must warn you, this style is not at all common in ruby community. Use regular if syntax instead.
