Multiple returns from a function (sorry, method!)

ruby-talk

Take a look at this method call:

(line,format_line)=replace_tabs(line,fmt_line,@current_ruler)

in the method replace_tabs, format line ha the right value,
but in the caller, its not receiving it.

This is how I'm returning the values:
return([line,format_line])

which I understand to mean that I'm returning an array, so I suppose I need
to know how to "unpack" the array into the two receiving values

Thanks

(line,format_line)=replace_tabs(line,fmt_line,@current_ruler)

line, format_line = replace_tabs(line, fmt_line, @current_ruler)

This is how I'm returning the values:
return([line,format_line])

return line, format_line

Doh!, it works - I just put in some debugging, andthe caller is getting the
values. Problem must be elsewhere.

Thanks, anyway!

return line, format_line

Both work as expected, but I find the latter much cleaner.
