Question

Ruby has a wealth of conditional constructs, including if/unless, while/until etc.

The while block from C:

while (condition) {     ... } 

can be directly translated to Ruby:

while condition      ... end 

However, I can’t seem to find a built-in equivalent in Ruby for a C-like do ... while block in which the block contents are executed at least once:

do {      ...  } while (condition); 

Any suggestions?

Answer 1

…The best I could come up with is the loop construct with a break at the end:

loop do     ...     break unless condition end
