You write a template for it. +Then there may be more than one line. You add a loop in the template. +Then there are some options made by the user, such as hidden columns. You add more to the template. +Then it lacks usability. You want it to be able to sort the data. You add code for that. +Then there are too many results, you need pagination, you want to print or export that data..... and so on. + +The ReportGenerator class was designed because this exact scenario happened about half a dozen times in Lx-Office. +It's purpose is to manage all those formating, culling, sorting, and templating. +Which makes it almost as complicated to use as doing the work for yourself. + +=head1 FUNCTIONS + +=over 4 + +=item new \%myconfig,$form,%options + +Creates a new ReportGenerator object, sets all given options, and returns it. + +=item set_columns %columns + +Sets the columns available to this report. + +=item set_column_order @columns + +Sets the order of columns. Any columns not present here are appended in alphabetic order. + +=item set_sort_indicator $column,$direction + +Sets sorting ot the table by specifying a column and a direction, where the direction will be evaluated to ascending if true. +Note that this is only for displaying. The data has to be presented already sorted. + +=item add_data \@data + +=item add_data \%data + +Adds data to the report. A given hash_ref is interpreted as a single line of data, every array_ref as a collection of lines. +Every line will be expected to be in a kay => value format. Note that the rows have to be already sorted. +ReportGenerator does only colum sorting on its own, and provides links to sorting and visual cue as to which column was sorted by. + +=item add_separator + +Adds a separator line to the report. + +=item add_control \%data + +Adds a control element to the data. Control elements are an experimental feature to add functionality to a report the regular data cannot. +Every control element needs to set IS_CONTROL_DATA, in order to be recongnized by the template. +Currently the only control element is a colspan element, which can be used as a mini header further down the report. + +=item clear_data + +Deletes all data filled into the report, but keeps options set. + +=item set_options %options + +Sets options. For an incomplete list of options, see section configuration. + +=item set_options_from_form + +Tries to import options from the $form object given at creation + +=item set_export_options $next_sub,@variable_list + +Sets next_sub and additional variables needed for export. + +=item get_attachment_basename + +Returns the set attachment_basename option, or 'report' if nothing was set. See configuration for the option. + +=item generate_with_headers + +Parses the report, adds headers and prints it out. Headers depend on the option 'output_format', +for example 'HTML' will add proper table headers, html headers and http headers. See configuration for this option. + +=item get_visible_columns $format + +Returns a list of columns that will be visible in the report after considering all options or match the given format. + +=item html_format $value + +Escapes HTML characters in $value and substitutes newlines with '
'. Returns the escaped $value. + +=item prepare_html_content $column,$name,@column_headers + +Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked. +Should not be called extrenally, since all render and generate functions invoke it anyway. + +=item generate_html_content + +The html generation function. Is invoked by generate_with_headers. + +=item generate_pdf_content + +The PDF generation function. It is invoked by generate_with_headers, tests whether or not the Perl module PDF::API2 is installed and calls render_pdf_with_pdf_api2 if it is and render_pdf_with_html2ps otherwise. + +=item generate_csv_content + +The CSV generation function. Uses XS_CSV to parse the information into csv. + +=item render_pdf_with_pdf_api2 + +PDF render function using the Perl module PDF::API2. + +=item render_pdf_with_html2ps + +PDF render function using the external application html2ps. + +=back + +=head1 CONFIGURATION + +These are known options and their defaults.

Supported options are HTML, CSV, and PDF. Default is HTML. + +=item allow_pdf_export + +Used to determine if a button for PDF export should be displayed. Default is yes. The PDF button is hidden if neither the Perl module PDF::API2 nor the external applications html2ps and Ghostscript are available regardless of this parameter's value. + +=item allow_csv_export + +Used to determine if a button for CSV export should be displayed.

Supported paper sizes are a3, a4, a5, letter and legal. + +=item orientation (landscape) + +Landscape or portrait. Default is landscape. + +=item font_name + +Default is Verdana. Supported font names are Courier, Georgia, Helvetica, Times and Verdana. This option only affects the rendering with PDF::API2. + +=item font_size + +Default is 7.
