( #3333=superdoc: print w/replies, xml ) Need Help??
Hi All. I need to split the string to a several substrings of the same length, the last substring should be blank padded so that it's length also would be the same. And - that's the problem - the string may be empty also.

That is what I've written
1) - ok on empty string, but on not empty string produce unnecessary blank substring

my $x = ""; $x=~s/(.{0,3})/"'$1".(' 'x(3-length($1)))."'\n"/eg; print $x --- ' ' my $x = "1234567890"; $x=~s/(.{0,3})/"'$1".(' 'x(3-length($1)))."'\n"/eg; print $x --- '123' '456' '789' '0 ' ' '
2) - ok on not empty string, but empty string is not padded
my $x = ""; $x=~s/(.{1,3})/"'$1".(' 'x(3-length($1)))."'\n"/eg; print $x --- ___prints_nothing___ my $x = "1234567890"; $x=~s/(.{1,3})/"'$1".(' 'x(3-length($1)))."'\n"/eg; print $x --- '123' '456' '789' '0 '
any advice?

Use:  <p> text here (a paragraph) </p>

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
