( [id://3333]=superdoc: print w/replies, xml ) Need Help??

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.
