Formatting text.

[Marcin Tyman]

Hi again
Is there any way to format a string. I.E. I've got a variable which may
be 1, 2, 3 and the variable is added to string. I want to show whole
string formatted as follows:
100
1
10
1100

not like that:
100
1
10
1100

Any help would be helpful (as always ;-) )

thanks in advance

Please look for printf, sprintf and % in the docs. The last one might
be hard to find. You use it as: "%3d" % 1

Kind regards

OK, Fine. But... I want to format the string not its output to redirect
the string to a file on remote machine (the file should be formatted).

sprintf and % return a string, they don't print anything to the screen. You
can write the result of "%3d" % 1 to a file without a problem.

Now what? Do you want to output or not? I do not understand your
remark because with the methods I listed you can do output as well as
change strings.

Same is true for rjust() : http://www.whytheluckystiff.net/ruby/pickaxe/html/ref_c_string.html#String.rjust
