NAME

Mojolicious::Plugin::ReplyTable - Easily render rectangular data in many formats using Mojolicious

SYNOPSIS

  use Mojolicious::Lite;
  plugin 'ReplyTable';

  my $format = [format => [qw(
    txt csv html json
    xls xlsx
  )]];
  any '/table' => $format => sub {
    my $c = shift;
    my $data = [
      [qw/a b c d/],
      [qw/e f g h/],
    ];
    $c->reply->table($data);
  };

  app->start;

DESCRIPTION

Mojolicious::Plugin::ReplyTable adds the reply->table helper which can render a table of data in one of several user-selected formats. The format is selected by the client via the usual Mojolicious Content Negotiation mechanisms.

Loading the plugin also sets up several MIME types (using Mojolicious::Types, see "types" in Mojolicious), and appends the module to the list of rendering classes (See "renderer" in Mojolicious).

HELPERS

reply->table

  $c->reply->table([[...], [...], ... ]]);
  $c->reply->table($default => $data, html => sub { ... });

Renders an arrayref of arrayrefs (the inner arrayref being a row) in one of several formats listed below. An optional leading argument is used as the default format when one is not otherwise requested. Optional trailing key-value pairs are merged into the arguments to "respond_to" in Mojolicious::Controller.

Any additional options, particularly those governing formatting details, are via stash keys prefixed by reply_table.. Note that the prefix reply_table.private. is reserved for internal use.

The formats currently include:

csv

Implemented via Text::CSV using the default values with binary enabled. To override these defaults set the stash key reply_table.csv_options to a hashref containing attributes to pass to Text::CSV. For example, to create a PSV (pipe delimited) file:

  $c->stash('reply_table.csv_options' => { sep_char => "|" });

See "new" in Text::CSV for available options.

html

Implemented via the standard Mojolicious rendering functionality and a template named reply_table. Setting the stash key reply_table.header_row to a true value will cause the default template to use the first row as header values. This default template may be overloaded to change the formatting, the table is available to the template via the stash key reply_table.table.

json

Implemented via the standard Mojo::JSON handling.

txt

A textual representation of the table. This format is intended for human consumption and the specific formatting should not be relied upon.

If Text::Table::Tiny is available, it will be used to format the data (can be overridden with reply_table.tablify). It can be controlled via the stash keys reply_table.header_row and reply_table.separate_rows as noted in that module's documentation. Otherwise it is generated via Mojo::Util::tablify.

xls

Binary Microsoft Excel format (for older editions of Excel), provided by optional module Spreadsheet::WriteExcel. If that module is not installed, the client will receive an error status 406.

xlsx

XML Microsoft Excel format (for newer editions of Excel), provided by optional module Excel::Writer::XLSX. If that module is not installed, the client will receive an error status 406.

METHODS

This module inherits all the methods from Mojolicious::Plugin and implements the following new ones

register

The typical mechanism of loading a Mojolicious::Plugin. No pass-in options are currently available.

FUTURE WORK

Beyond what is mentioned in the specifc formats above, the following work is planned. If any of it tickles your fancy, pull-requests are always welcome.

• Better tests for generated Excel documents.

• Exposing the formatters so that they can be used directly.

• Add additional formats, like OpenOffice/LibreOffice. If needed these can be appended via additional handlers to the helper.

A NOTE ON FORMAT DETECTION

As of Mojolicious version 9.11, format detection is disabled by default. To enable it you can pass an array reference of [format=>\@formats] to the route, where @formats is the supported file extensions. You may also use the shortcut [format = 1] >> to enable detection of any format, though that may change in the future.

As of Mojolicious 9.16 you can inherit these formats from a parent route:

  my $with_formats = $app->routes->any([format => \@formats]);
  $with_formats->get('/data')->to('MyController#my_action');
