I have a script to do several operations, based on the various options
provided from command line.
For that I have created the help text (script.pl --help). The text is
huge (exceeding 1 page) and I can not cut down on that.
So when users (one who uses my script) asks for help, it just scrolls
off (expected).
Now I've been asked to display the text in the way man pages are
displayed (scrollable up & down), or atleast in "script.pl --help |
more" way... i.e., scrolling in one direction.
Is this possible using perl and how? Any sample code (or link) would
help me do things quick
Assuming that your help text is in POD format:
#!/usr/bin/perl
use warnings;
use strict;
# Your code here
sub help {
0 == system perldoc => $0 # Run perldoc on myself
or die "system perldoc => $0 failed: $?";
}
