G'day ibm1620,

You can achieve that with this code:

#!/usr/bin/env perl use strict; use warnings; my $scale = '1.......10........20........30........40........50........60'; my $max_width = length($scale) - 1; my $long_string = q{The quick brown fox jumps over the lazy dog}; my @records = ( [qw{79.3 2022 1 8}, $long_string], [qw{394571 22 10 81}, $long_string], [qw{123456.78 12345 123 1234}, $long_string], ); my $sprintf_fmt = '%.2f %d %d %d %n'; my $printf_fmt = "%s%.*s|\n"; print "$scale\n"; for my $record (@records) { my $used_so_far; printf $printf_fmt, sprintf($sprintf_fmt, @{$record}[0..3], $used_so_far), $max_width - $used_so_far, $record->[4]; }

Output:

1.......10........20........30........40........50........60 79.30 2022 1 8 The quick brown fox jumps over the lazy dog| 394571.00 22 10 81 The quick brown fox jumps over the lazy| 123456.78 12345 123 1234 The quick brown fox jumps over th|

Update: I've just noticed the '%.2f %d %d %d  %n' format would've been better as '%.2f %d/%d/%d  %n' to align with the original OP code. However, it's purely cosmetic and doesn't affect the functionality or the technique being demonstrated.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
