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 kivitendo. +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 by 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 of 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 have already been sorted when it was added. + +=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 key => value format. Note that the rows have to already have been +sorted. + +The ReportGenerator is only able to display pre-sorted data and to indicate by +which column and in which direction the data has been sorted via visual clues +in the column headers. It also provides links to invert the sort direction. + +=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 recognized 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 added to 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 externally, 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 and renders the PDF with the PDF::API2 library. + +If the param want_binary_pdf is set, the binary pdf stream will be returned. +If $pdfopts->{print} && $pdfopts->{printer_id} are set, the pdf will be printed (output is directed to print command). + +Otherwise and the default a html form with a downloadable file is returned. + +=item generate_csv_content + +The CSV generation function. Uses XS_CSV to parse the information into csv. + +=back + +=head1 CONFIGURATION + +These are known options and their defaults. Options for pdf export and csv export need to be set as a hashref inside the export option. + +=head2 General Options + +=over 4 + +=item std_column_visibility + +Standard column visibility. Used if no visibility is set. Use this to save the trouble of enabling every column. Default is no. + +=item output_format + +Output format. Used by generate_with_headers to determine the format. 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. + +=item allow_csv_export + +Used to determine if a button for CSV export should be displayed. Default is yes. + +=item html_template + +The template to be used for HTML reports. Default is 'report_generator/html_report'. + +=item controller_class + +If this is used from a C based controller class, pass the +class name here and make sure C is +used in the controller. That way the exports stay functional. + +=back + +=head2 PDF Options + +=over 4 + +=item paper_size + +Paper size. Default is a4. 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.
