Urgent help: getoptions::long to execute a command.

P

perl_newbie

I have created a data structure that checks the hierarchy list to a
list found in cadence. I'd like to use the getopt::long package to do
the following but do not know if this could be done.

1) when the flag 'unused' is chosen then it should get the $cadecells
and have them be executed by a command to remove them
"dssc remove $cadcell"

2)I am unable to reference the $hier->{$cell} in my last subroutine.
the $hierec->{$cell} contains the $lib but when I use the
data::Dumper;the $hierec->{$cell} ;which should have all $lib shows up
empty, why?.

use strict
use Getopt::Long;
use Data::Dumper;
my $show_file={};
my $hierec={};
my $cell={};
my $lib={};
my $cadcell={};
my $cadlib={};
my @cell=();

if (! & GetOptions('help', 'unused'))
{ print"Invalid Flag. please try -help.\n";}

if (@ARGV == 2 )
{
my $list1=$ARGV[0];
my $list2=$ARGV[1];

open(L1,"<$list1") || die "cannot open first file";
open(L2,"<$list2") || die "cannot open second file";
}
if (! my $opt_nosyntax)
{
print ("\nARGS were: ",join(" ",@ARGV),"\n");
print ("\nSYNTAX is:\n",
"hierarchy_list cadence_list <Flag_options>\n");
print("\tFlag_options include:\n");
print("\t\t-help\n");
print("\t\t-unused\n");
}
while(<L1>)
{
$show_file=$_;

if ($show_file=~/^\s?(\S+)\s+(\S+)/)
{
my ( $cell, $lib)= ($2, $1);
$hierec->{$cell}->{$lib}=1;
}
}
&comp_2_cell_list;
sub comp_2_cell_list
{
foreach(<L2>)
{
if(~/^\s?(\S+)\s+(\S+)/)
{

my ($cadlib,$cadcell)=($1,$2);
if(! exists($hierec->{$cadcell}))
{
print "list to dump: $cadcell\n";
}
unless ( exists $hierec->{$cell}->{$cadlib})
cannot obtain the keys from my hash to be reference here for comparing
if the same cell is found in the same lib. help???
{
print "mismatch in:{$hierec} ($hierec->{$cell},$cadlib)\n";
}

}
}
}

really? Then why does this look as though it has been typed in as an afterthought
ie no semi-colon. You need to copy and paste code, not retype it. You also need

use warnings;

Read the posting guidelines.
use Getopt::Long;
use Data::Dumper;
my $show_file={};
my $hierec={};
my $cell={};
my $lib={};
my $cadcell={};
my $cadlib={};
my @cell=();

if (! & GetOptions('help', 'unused'))

You need to read the documentation for Getopt::Long, not just guess how it is used.
{ print"Invalid Flag. please try -help.\n";}

if (@ARGV == 2 )
{
my $list1=$ARGV[0];
my $list2=$ARGV[1];

open(L1,"<$list1") || die "cannot open first file";
open(L2,"<$list2") || die "cannot open second file";
}
if (! my $opt_nosyntax)
Click to expand...
This if statement is *never* going to be false. You declare $opt_nosyntanx, assign
no value to it, and then check if it contains a false value. It cannot be anything
else.

<snip>
I'm not going to proceed any further. You need to fix these fundamental issues
before any further diagnosis can be attempted. You also need to read the posting
guidelines: post the smallest complete script (that compiles out of the box - the
one already posted doesn't) that exhibits the behaviour that you are trying to
demonstrate, and let us know what the expected and actual output are.

thank you Tad and Mark for your comments. I still have some problems
implementing the the getoption::long to retire unused cells. I believe
the 'help' option is okay now but i need more help. I have posted the
smallest program possible that can I show to demostrate output. Will
you please help me figure out how to use the -unused option to push it
to another file to later run it to remove the unused cell from the cad
tree? can you also tell me how to reference my $hierc->{$cell} into my
subroutine? I have tried several ways to reference the hash which
contains my library to compare it to the cad tree libraries the cell is
found in but had no luck doing so.

Thank you Mark and Tad for your comments and help. Quick

question when the documents do not make are too difficult for a new
perl user? Again, thank you all for your comments and help :^)

Huh?

I search the FAQ list, look up a function using perldoc, use Google, look
the concept up in "Programming Perl" or even "Learning Perl", sometimes.

I do not see what makes you think you are above putting effort into
finding a solution to your problem.

You have been working on this program for months now, and you don't seem
to have listened to much of the advice.
