Hi ,
Firstly, Thanks for strawberry perl it's making my life alot easier.
Think I may have found a bug within the File::Compare module.
Basically I get different results with
File::Compare::compare_text
when comparing files in same directory as script to when comparison files
are in another directory.
To test script you will have to create a directory ''anotherDirectory"
which is below the working script directory.
use File::Compare;
use FileHandle;
use File::Compare 'cmp';
sub munge($) {
my $line = $_[0];
for ($line) {
s/^\s+//; # Trim leading whitespace.
s/\s+$//; # Trim trailing whitespace.
}
return uc($line);
}
sub Convert_Upper{
my $in = $_[0];
for ($in) {
s/^\s+//; # Trim leading whitespace.
s/\s+$//; # Trim trailing whitespace.
}
my $out = uc($in);
return uc($in);
}
sub CompareFiles{
my ($First_line,$Second_line) = @_;
print "CompareFiles..1st...$First_line\n";
print "CompareFiles...2nd...$Second_line\n";
$First_line = &Convert_Upper($First_line);
$Second_line = &Convert_Upper($Second_line);
print "CompareFiles..1st..compare lines...$First_line.\n";
print "CompareFiles..2nd..compare lines...$Second_line.\n";
if($First_line eq $Second_line){
return 0;
}
else
{
return 1;
}
}
#
# create 3 files: file1.txt and file2.txt are identical but ileDiff.txt
is different to the others
#
#below code works.....
print "compare files that are in same directory as script \n";
print "\n";
printf "file1 and fileDiff are %s.\n",
compare("file1.txt","fileDiff.txt") ? "different" : "identical";
if ( File::Compare::compare_text("file1.txt","file2.txt", sub{
CompareFiles(@_) } )) {
print "sub....file1 and file2 are different.\n";
}
else{
print "sub...file1 and file2 are identical.\n";
}
#
# but now place files in another directory...as below....this doesn't
work.....I've also tried file handles ?
#
print ".......\n";
print "compare files that are in another directory as script \n";
print "\n";
printf "file1 and fileDiff are %s.\n",
compare(".\anotherDirectory\file1.txt",".\anotherDirectory\fileDiff.txt") ?
"different" : "identical";
if (
File::Compare::compare_text(".\anotherDirectory\file1.txt",".\anotherDirectory\file2.txt",
sub{ CompareFiles(@_) } )) {
print "sub....file1 and file2 are different.\n";
}
else{
print "sub...file1 and file2 are identical.\n";
}
