Hi all,

I am new to Perl (I used to be a C/C++ user). And I want to write a file convertor in Perl to learn it. And I use ActivePerl.

// Input.txt context
s 1 2
a 4 5
a 9 8

// Output.txt context I want
Sub (wire1, wire2);
Add (wire4, wire5);
Add (wire9, wire8);

BTW, how to debug perl script in ActivePerl? can I set breakpoint in it?

Any suggestions will be appreciated!
Best regards,
Davy
 

if i'm not wrong activeperl only provides the interpreter on Windows. the command-based interpreter does not support debugging (e.g. breakpoint etc.)

you may have to google for "Perl IDE". some are commercial, some are free.

one example: **broken link removed**

Here is one script in perl which I wrote now and tested... it's working properly.. the input is t.txt file. The o/p will be o.txt.




#/usr/local/bin/perl -w

open(T,"<./t.txt") or die ("Could not open input file"); # input file is t.txt
open(O,">./o.txt"); # The output file is o.txt

foreach $line (<T>)
{
$line =~ s/^\s+//;
if($line)
{
($m,$n,$o) = split(' ',$line);
if($m eq "s")
{$m1=Sub;}
else
{$m1=Add;}
print O "$m1 \(wire$n, wire$o\)\;\n";
}
}

close(T);
close(O);
