in reply to Re^5: comparing contents of two arrays and output differences
in thread comparing contents of two arrays and output differences

Dear 2Teez,

I've been trying to solve my little programming problem using the module, however, due to my lack of experience, I somehow have not been able to run the comparison properly

What I did not understand in the CPAN description was the fact that only one array is used for the comparison, e.g.

diff \@a, $b { STYLE => "Table" };

I would have expected to have two @arrays for comparision, e.g.

my @xml_files = glob( '*xml' ); #say for @xml_files; my @bak_files = glob( '*bak' ); #say for @bak_files; #using the Text::Diff::Table for comparison my $format = ""; my @joint_files = @xml_files, @bak_files; my @results = diff \@joint_files, $format { STYLE => "Table" }; say for @results;

However, I am getting the following error message, saying that the module is not install properly

C:\dev>perl comparing_files_3_using_text_diff.pl ./file_compare_on_lis +ts Can't locate package Text::Diff::Base for @Text::Diff::Table::ISA at c +omparing_f iles_3_using_text_diff.pl line 4. Backslash found where operator expected at comparing_files_3_using_tex +t_diff.pl line 20, near "diff \" (Do you need to predeclare diff?) syntax error at comparing_files_3_using_text_diff.pl line 20, near "di +ff \" Global symbol "%format" requires explicit package name at comparing_fi +les_3_usin g_text_diff.pl line 20. Global symbol "@results" requires explicit package name at comparing_f +iles_3_using_text_diff.pl line 22.

I suppose I have to use the module as is, but what does $b represent and why can't it be changed to $format?

Could somebody give me a hint why I am getting the error message despite the module being installed?

I am confused about these package name declaration, I thought I did everything by the book

Thanks a mil in advance for your support

Kind regards

C.
