Provide fetchrow_hashref() for CSV files Text::CSV_PP::Iterator is a Perl module to provide fetchrow_hashref() for CSV files.Synopsis use Text::CSV_PP::Iterator; my($parser) = Text::CSV_PP::Iterator -> new ({ column_names => , file_name => 'no.heading.in.file.csv', }); my($hashref); while ($hashref = $parser -> fetchrow_hashref() ) { print map{"$_ => $$hashref{$_}. "} sort keys %$hashref; print " "; }Text::CSV_PP::Iterator is a pure Perl module.It is a convenient wrapper around Text::CSV_PP. Points of interest: o Text::CSV_PP::Iterator reads the file for you, using Iterator::IO. Warning: Iterator::IO V 0.02 has 3 bugs in it, where it does not call throw() properly. I've reported this via http://rt.cpan.org o All of Text::CSV_PP's new() parameters are supported by the fact that Text::CSV_PP::Iterator subclasses Text::CSV_PP o All data is returned as a hashref just like DBI's fetchrow_hashref(), using Text::CSV_PP::Iterator's only method, fetchrow_hashref() o The module reads the column headers from the first record in the file, or ... o The column headers can be passed in to new() if the file has none o Non-existent file errors throw the exception Iterator::X::IO_Error, which stringifies to a nice error message if you don't catch it o EOF returns undef to allow this neat construct: while ($hashref = $parser -> fetchrow_hashref() ){...} o Dependencies: - Iterator::IO - Text::CSV_PP o Example code: t/test.t demonstrates: - How to call fetchrow_hashref in isolation and in a loop - How to call fetchrow_hashref in eval{...} and catch exceptions Requirements: · Perl
