=head1 DESCRIPTION

This documentation is written to explain ways to use this module when writing your own excel
parser.  To use the general package for excel parsing out of the box please review the
documentation for L<Workbooks|Spreadsheet::XLSX::Reader::LibXML>,
L<Worksheets|Spreadsheet::XLSX::Reader::LibXML::Worksheet>, and
L<Cells|Spreadsheet::XLSX::Reader::LibXML::Cell>

This L<Moose> class contains two L<attributes|Moose::Manual::Attributes>.  It is intended
to be used through (by) L<delegation|Moose::Manual::Delegation> in other classes.  The first
attribute is used to store the current error string.  The second, is set to turn on or off
pushing the error string to STDERR when the first attribute is (re)set.

=head2 Attributes

Data passed to new when creating an instance.   For modification of
these attributes see the listed 'attribute methods'. For more information on
attributes see L<Moose::Manual::Attributes>.

=head3 error_string

=over

B<Definition:> This stores an error string for recall later.

B<Default> undef (init_arg = undef)

B<Range> any string (error objects with the 'as_string' or 'message' are auto coerced to
a string)

B<attribute methods> Methods provided to adjust this attribute

=back

=head4 error

=over

B<Definition:> returns the currently stored error string

=back

=head4 clear_error

=over

B<Definition:> clears the currently stored error string

=back

=head4 set_error( $error_string )

=over

B<Definition:> sets the attribute with $error_string.

=back

=head3 should_warn

=over

B<Definition:> This determines if the package will push any low level errors logged
during processing to STDERR when they occur. (rather than just made available) It
should be noted that failures that kill the package should push to STDERR by default.
If your Excel sheet is malformed it can error without failing.  Sometimes this package
will handle those cases correctly and sometimes it wont.  If you want to know more
behind the scenes about the unexpected behaviour of the sheet then turn this attribute
on.

B<Default> 1 -> it will push to STDERR

B<Range> Boolean values

B<attribute methods> Methods provided to adjust this attribute

=back

=head4 set_warnings( $bool )

=over

B<Definition:> Turn pushed warnings on or off

=back

=head4 if_warn

=over

B<Definition:> Returns the current setting of this attribute

=back

=head3 spew_longmess

=over

B<Definition:> This (the Error) class is capable of pulling the L<Carp/longmess>
for each error in order to understand what happened.  If that is just too much
you can change the behaviour

B<Default> 1 -> it will pull the longmess (using Carp);

B<Range> Boolean values

B<attribute methods> Methods provided to adjust this attribute

=back

=head4 should_spew_longmess( $bool )

=over

B<Definition:> add the longmess to errors

=back

=head4 spewing_longmess

=over

B<Definition:> Returns the current setting of this attribute

=back

=head1 SUPPORT

=over

L<github Spreadsheet::XLSX::Reader::LibXML/issues
|https://github.com/jandrew/Spreadsheet-XLSX-Reader-LibXML/issues>

=back

=head1 TODO

=over

B<1.> get clases in this package to return error numbers and or error strings and
then provide opportunity for this class to localize.
B<2.> Get the @CARP_NOT section to work and skip most of the Moose level reporting
