NAME

Mojolicious::Plugin::BootstrapHelpers - Type less bootstrap

SYNOPSIS

# Mojolicious
$self->plugin('BootstrapHelpers');

# ::Lite
plugin 'BootstrapHelpers';

# Meanwhile, somewhere in a template...
%= formgroup 'Email', text_field => ['email'], large, cols => { small => [3, 9] }

# ...that renders into
<div class="form-group form-group-lg">
    <label class="control-label col-sm-3" for="email">Email</label>
    <div class="col-sm-9">
        <input class="form-control" id="email" name="email" type="text">
    </div>
</div>

STATUS

This is an unstable work in progress. Backwards compatibility is currently not to be expected between releases.

Currently supported Bootstrap version: 3.3.0.

Currently only Perl 5.20+ is supported (thanks to postderef).

DESCRIPTION

Mojolicious::Plugin::BootstrapHelpers is a convenience plugin that reduces some bootstrap complexity by introducing several tag helpers specifically for Bootstrap 3.

The goal is not to have tag helpers for everything, but for common use cases.

All examples below (and more, see tests) is expected to work.

How to use Bootstrap

If you don't know what Bootstrap is, see http://www.getbootstrap.com/ for possible usages.

You might want to use Mojolicious::Plugin::Bootstrap3 in your templates.

To get going quickly by using the official CDN you can use the following helpers:

# CSS
%= bootstrap

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

# or (if you want to use the theme)
%= bootstrap 'theme'

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">

# And the javascript
%= bootstrap 'js'

<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

# Or just:
%= bootstrap 'all'

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

It is also possible to automatically include jQuery (2.*)

%= bootstrap 'jsq'

<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

%= bootstrap 'allq'

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">
<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>

Strappings

There are several shortcuts ("strappings") for applying context and size classes that automatically expands to the correct class depending on which tag it is applied to. For instance, if you apply the info strapping to a panel, it becomes panel-info, but when applied to a button it becomes btn-info.

You can use them in two different ways, but internally they are the same. These to lines are exactly identical:

%= button 'Push me', primary

%= button 'Push me', __primary => 1

For sizes, you can only use the longform (xsmall, small, medium and large) no matter if you use the short strapping form or not. They are shortened to the Bootstrap type classes.

The following strappings are available:

xsmall    default     striped       caret     right
small     primary     bordered
medium    success     hover
large     info        condensed
          warning     responsive
          danger

Add two leading underscores if you don't want to use the short form.

See below for usage. Important: You can't follow a short form strapping with a fat comma (=>). The fat comma auto-quotes the strapping, and then it breaks.

If there is no corresponding class for the element you add the strapping to it is silently not applied.

The short form is recommended for readability, but it does setup several helpers in your templates. You can turn off the short forms, see init_short_strappings.

Syntax convention

In the syntax sections below the following conventions are used:

name            A specific string
$name           Any string
%name           One or more key-value pairs, written as:
                  key => 'value', key2 => 'value2'
                     or, if you use short form strappings:
                  primary, large
$key => [...]   Both of these are array references where the ordering of strings
key  => [...]     are significant, for example:
                  key => [ $thing, $thing2, %hash ]
$key => {...}   Both of these are hash references where the ordering of pairs are
key  => {...}     are insignificant, for example:
                  key => { key2 => $value, key3 => 'othervalue' }
(...)           Anything between parenthesis is optional. The parenthesis is not part of the
                  actual syntax
|...|           Two pipes is a reference to another specification. For instance, button toolbars contain
                  button groups that contain buttons. Using this syntax makes the important parts clearer.
                  The pipes are not part of the actual syntax.

Ordering between two hashes that follows each other is also not significant.

About %has

The following applies to all %has hashes below:

They refer to any html attributes and/or strappings to apply to the current element.
When helpers are nested, all occurrencies are change to tag-specific names, such as %panel_has.
This hash is always optional. It is not marked so in the definitions below in order to reduce clutter.
Depending on context either the leading or following comma is optional together with the hash. It is usually obvious.
Sometimes on nested helpers (such as tables in panels just below), %has is the only thing that can be applied to the other element. In this case panel => { %panel_has }. It follows from above that in those cases this entire expression is also optional. Such cases are also not marked as optional in syntax definitions and are not mentioned in syntax description, unless they need further comment.

From this definition:

%= table ($title,) %table_has, panel => { %panel_has }, begin
       $body
%  end

Both of these are legal:

# since both panel => { %panel_has } and %table_has are hashes, their ordering is not significant.
%= table 'Heading Table', panel => { success }, condensed, id => 'the-table', begin
     <tr><td>A Table Cell</td></tr>
%  end


%= table begin
     <tr><td>A Table Cell</td></tr>
%  end

References

|link|

|link| creates an <a> tag.

|link|

Is exactly the same as

$link_text, [ $url ], %link_has

$link_text

Mandatory. The text on the link.

$url

Mandatory. It sets the href on the link. url_for is used to create the link.

%link_has

Which strappings are available varies depending on context.

|item|

|item| is used in the various submenus/dropdowns. One |item| creates one <li> tag.

|item|

Is exactly the same as

[ |link| ]

# or
$header_text

# or
[]

So, a submenu item can be one of three things:

1. A link, in which case you create a |link| in an array reference.
2. A .dropdown-header, in which case you give it a 'string' which then is turned into the text of the header.
3. A .divider, in which case you give it an empty array reference.

See "Dropdowns", "Button groups" and "Navbars" for examples.

HELPERS

Bootstrap documentation

Badges

Syntax

%= badge $text, %has

$text

Mandatory. If it is undef no output is produced.

Available strappings

right applies .pull-right.

Examples

<%= badge '3' %>

<span class="badge">3</span></a>

A basic badge.

<%= badge '4', data => { custom => 'yes' }, right %>

<span class="badge pull-right" data-custom="yes">4</span>

A right aligned badge with a data attribute.

Buttons

Bootstrap documentation

Syntax

%= button $button_text(, [$url]), %has

%= submit_button $text, %has

$button_text

Mandatory. The text on the button.

[$url]

Optional array reference. It is handed off to url_for, so with it this is basically link_to with Bootstrap classes.

Not available for submit_button.

Available strappings

default primary success info warning danger link applies the various .btn-* classes.

large small xsmall applies .btn-lg .btn-sm .btn-xs respectively.

active block applies the .active and .block classes.

disabled applies the .disabled class if the generated element is an <a>. On a <button> it applies the disabled="disabled" attribute.

Examples

%= button 'The example 5' => large, warning

<button class="btn btn-lg btn-warning" type="button">The example 5</button>

An ordinary button, with applied strappings.

%= button 'The example 1' => ['http://www.example.com/'], small

<a class="btn btn-default btn-sm" href="http://www.example.com/">The example 1</a>

With a url the button turns into a link.

%= submit_button 'Save 2', primary

<button class="btn btn-primary" type="submit">Save 2</button>

A submit button for use in forms. It overrides the build-in submit_button helper.

Button groups

Syntax

There are two different syntaxes. One for single-button groups and one for multi-button groups. The difference is that single-button groups can't change anything concerning the buttongroup (e.g. it can't be justified). If you need to do that there is nothing wrong with having a multi-button group with just one button.

# multi button
<%= buttongroup %has,
                buttons => [
                    [ |button|,
                      (items => [ |item| ])
                    ]
                ]
%>

# single button
<%= buttongroup [ |button|,
                  (items => [ |item| ])
                ]
%>

buttons => []

The single-button style is a shortcut for the buttons array reference. It takes ordinary buttons, with two differences: The items array reference, and it is unnecessary to give a button with items a url.

items => [...]

Giving a button an items array reference consisting of one or many |item| creates a dropdown like submenu. Read more under "item".

Examples

<%= buttongroup
    buttons => [
        ['Button 1'],
        ['Button 2'],
        ['Button 3'],
    ]
%>

<div class="btn-group">
    <button class="btn btn-default" type="button">Button 1</button>
    <button class="btn btn-default" type="button">Button 2</button>
    <button class="btn btn-default" type="button">Button 3</button>
</div>

A basic button group.

<%= buttongroup small,
    buttons => [
        ['Button 1'],
        ['Dropdown 1', caret, items => [
            ['Item 1', ['item1'] ],
            ['Item 2', ['item2'] ],
            [],
            ['Item 3', ['item3'] ],
        ] ],
        ['Button 2'],
        ['Button 3'],
    ],
%>

<div class="btn-group btn-group-sm">
    <button class="btn btn-default" type="button">Button 1</button>
    <div class="btn-group btn-group-sm">
        <button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown">Dropdown 1 <span class="caret"></span>
        </button>
        <ul class="dropdown-menu">
            <li><a class="menuitem" href="item1" tabindex="-1">Item 1</a></li>
            <li><a class="menuitem" href="item2" tabindex="-1">Item 2</a></li>
            <li class="divider"></li>
            <li><a class="menuitem" href="item3" tabindex="-1">Item 3</a></li>
        </ul>
    </div>
    <button class="btn btn-default" type="button">Button 2</button>
    <button class="btn btn-default" type="button">Button 3</button>
</div>

Nested button group. Note that the small strapping is only necessary once. The same classes are automatically applied to the nested .btn-group.

<%= buttongroup vertical,
    buttons => [
        ['Button 1'],
        ['Dropdown 1', caret, items => [

              ['Item 3', ['item3'] ],
        ] ],
        ['Button 2'],
        ['Button 3'],
    ],
%>

%>

groups => [ { |button_group| } ]

A mandatory array reference of button groups.

Examples

<%= toolbar id => 'my-toolbar',
            groups => [

Dropdowns

Syntax

<%= dropdown  %has,
              [ |button|, items  => [ |item| ]
              ]

[ |button| ]

Mandatory array reference. It takes an ordinary button, with two differences: The items array reference, and it is unnecessary to give a button with items a url.

items

Mandatory array reference consisting of one or many |item|. Read more under "item".

Available strappings

caret adds a <span class="caret"></span<> element on the button.

Examples

<%= dropdown
     ['Dropdown 1', id => 'a_custom_id', right, items => [
        ['Item 1', ['item1'] ],
        ['Item 2', ['item2'] ],

        <li class="divider"></li>
        <li><a class="menuitem" href="item3" tabindex="-1">Item 3</a></li>
    </ul>
</div>

By default, tabindex is set to -1...

<%= dropdown
     ['Dropdown 2', caret, large, primary, items => [
        ['Item 1', ['item1'], data => { attr => 2 } ],
        ['Item 2', ['item2'], disabled, data => { attr => 4 } ],
        [],
        ['Item 3', ['item3'], data => { attr => 7 } ],
        [],
        ['Item 4', ['item4'], tabindex => 4 ],
        'This is a header',
        ['Item 5', ['item5'] ],
     ] ] %>

<div class="dropdown">
    <button class="btn btn-lg btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown 2 <span class="caret"></span></button>
    <ul class="dropdown-menu">
        <li><a class="menuitem" href="item1" tabindex="-1" data-attr="2">Item 1</a></li>
        <li class="disabled"><a class="menuitem" href="item2" tabindex="-1" data-attr="4">Item 2</a></li>

        <li class="divider"></li>
        <li><a class="menuitem" href="item4" tabindex="4">Item 4</a></li>
        <li class="dropdown-header">This is a header</li>
        <li><a class="menuitem" href="item5" tabindex="-1">Item 5</a></li>
    </ul>
</div>

...but it can be overridden.

Form groups

Bootstrap documentation

Syntax

<%= formgroup ($labeltext,)
               %formgroup_has,
              (cols => { $size => [ $label_columns, $input_columns ], (...) })
               $fieldtype => [
                   $input_name,
                  ($input_value,)
                   %input_has,
              ]

%>

# The $labeltext can also be given in the body
%= formgroup <as above>, begin
    $labeltext
%  end

$labeltext

Optional. It is either the first argument, or placed in the body. It creates a label element before the input.

cols

Optional. It is only used when the form is a .form-horizontal. You can defined the widths for one or more or all of the sizes. See examples.

$size

Mandatory. It is one of xsmall, small, medium or large. $size takes a two item array reference.

$label_columns

Mandatory. The number of columns that should be used by the label for that size of screen. Applies .col-$size-$label_columns on the label.

$input_columns

Mandatory. The number of columns that should be used by the input for that size of screen. Applies .col-$size-$input_columns around the input.

$fieldtype

Mandatory. Is one of text_field, password_field, datetime_field, date_field, month_field, time_field, week_field, number_field, email_field, url_field, search_field, tel_field, color_field.

There can be only one $fieldtype per formgroup.

$name

Mandatory. It sets both the id and name of the input field. If the $name contains dashes then those are translated into underscores when setting the name. If id exists in %input_has then that is used for the id instead.

$input_value

Optional. If you prefer you can set value in %input_has instead. (But don't do both for the same field.)

Examples

%= formgroup 'Text test 1', text_field => ['test_text']

<div class="form-group">
    <label class="control-label" for="test_text">Text test 1</label>
    <input class="form-control" id="test_text" name="test_text" type="text" />
</div>

The first item in the array ref is used for both id and name. Except...

%= formgroup 'Text test 4', text_field => ['test-text', large]

<div class="form-group">
    <label class="control-label" for="test-text">Text test 4</label>
    <input class="form-control input-lg" id="test-text" name="test_text" type="text" />
</div>

...if the input name (the first item in the text_field array ref) contains dashes -- those are replaced (in the name) to underscores.

%= formgroup 'Text test 5', text_field => ['test_text', '200' ]

<div class="form-group">
    <label class="control-label" for="test_text">Text test 5</label>
    <input class="form-control" id="test_text" name="test_text" type="text" value="200" />
</div>

An input with a value.

<form class="form-horizontal">
    %= formgroup 'Text test 6', text_field => ['test_text'], large, cols => { small => [2, 10] }
</form>

<form class="form-horizontal">
    <div class="form-group form-group-lg">
        <label class="control-label col-sm-2" for="test_text">Text test 6</label>
        <div class="col-sm-10">
            <input class="form-control" id="test_text" name="test_text" type="text">
        </div>
    </div>
</form>

Note the difference with the earlier example. Here large is outside the text_field array reference, and therefore .form-group-lg is applied to the form group.

%= formgroup 'Text test 8', text_field => ['test_text'], cols => { medium => [2, 10], small => [4, 8] }

<div class="form-group">
    <label class="control-label col-md-2 col-sm-4" for="test_text">Text test 8</label>
    <div class="col-md-10 col-sm-8">
        <input class="form-control" id="test_text" name="test_text" type="text" />
    </div>
</div>

A formgroup used in a .form-horizontal form. (Note that in this context, medium and large are not short form strappings. Those don't take arguments.)

Icons

This helper needs to be activated separately, see options below.

Syntax

%= icon $icon_name

$icon_name

Mandatory. The specific icon you wish to create. Possible values depends on your icon pack.

Examples

<%= icon 'copyright-mark' %>
%= icon 'sort-by-attributes-alt'

<span class="glyphicon glyphicon-copyright-mark"></span>
<span class="glyphicon glyphicon-sort-by-attributes-alt"></span>

Input groups

Syntax

<%= input %has,
          (prepend => ...,)
          input => { |input_field| },
          (append => ...)
%>

input => { }

Mandatory hash reference. The content is handed off to input_tag in Mojolicious::Plugin::TagHelpers.

prepend and append

Both are optional, but input groups don't make sense if neither is present. They take the same arguments, but there are a few to choose from:

prepend => $string

prepend => { check_box => [ |check_box| ] }

Creates a checkbox by giving its content to check_box in Mojolicious::Plugin::TagHelpers.

prepend => { radio_button => [ |radio_button| ] }

Creates a radiobutton by giving its content to radio_button in Mojolicious::Plugin::TagHelpers.

prepend => { buttongroup => { |buttongroup| }

Creates a single button buttongroup. See button groups for details.

prepend => { buttongroup => [ |buttongroup| ]

Creates a multi button buttongroup. See button groups for details.

Examples

<%= input input => { text_field => ['username'] },
          prepend => { check_box => ['agreed'] }
%>

<div class="input-group">
    <span class="input-group-addon"><input name="agreed" type="checkbox" /></span>
    <input class="form-control" id="username" type="text" name="username" />
</div>

An input group with a checkbox.

<%= input large,
          prepend => { radio_button => ['yes'] },
          input => { text_field => ['username'] },
          append => '@'
%>

<div class="input-group input-group-lg">
    <span class="input-group-addon"><input name="yes" type="radio" /></span>
    <input class="form-control" id="username" type="text" name="username" />
    <span class="input-group-addon">@</span>

          append => { button => ['Click me!'] },
%>

<div class="input-group">
    <input class="form-control" id="username" type="text" name="username" />
    <span class="input-group-btn"><button class="btn btn-default" type="button">Click me!</button></span>
</div>

An input group with a button.

<%= input input  => { text_field => ['username'] },
          append => { buttongroup => [['The button', caret, right, items => [

                              ['Item 2', ['item2'] ],
                              [],
                              ['Item 3', ['item3'] ],
                          ] ] ]
                    }
%>

<div class="input-group">
    <input class="form-control" id="username" type="text" name="username" />
    <div class="input-group-btn">
        <button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown">The button <span class="caret"></span>

Navs

Syntax

<%= nav %has,
        $type => [ |link|,
                  (items => [ |item| ])
                ]
%>

Navs are syntactically similar to button groups.

$type => [...]

Mandatory. $type is either pills or tabs (or items if the nav is in a navbar) and applies the adequate class to the surrounding ul.

items => [ |item| ]

If present does the same as items in dropdown. Also see "item".

Examples

<%= nav pills => [
            ['Item 1', ['#'] ],
            ['Item 2', ['#'], active ],
            ['Item 3', ['#'] ],
            ['Item 4', ['#'], disabled ],
        ]
%>

<ul class="nav nav-pills">
    <li><a href="#">Item 1</a></li>
    <li class="active"><a href="#">Item 2</a></li>
    <li><a href="#">Item 3</a></li>
    <li class="disabled"><a href="#">Item 4</a></li>
</ul>

A simple pills navigation.

<%= nav justified, id => 'my-nav', tabs => [
            ['Item 1', ['#'] ],
            ['Item 2', ['#'], active ],
            ['Item 3', ['#'] ],
            ['Dropdown', ['#'], caret, items => [
                    ['There are...', ['#'] ],
                    ['...three...', ['#'] ],
                    [],
                    ['...choices', ['#'] ],
                ],
            ],
        ]
%>

<ul class="nav nav-justified nav-tabs" id="my-nav">
    <li><a href="#">Item 1</a></li>
    <li class="active"><a href="#">Item 2</a></li>
    <li><a href="#">Item 3</a></li>
    <li class="dropdown">
        <a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown <span class="caret"></span></a>
        <ul class="dropdown-menu">
            <li><a href="#">There are...</a></li>
            <li><a href="#">...three...</a></li>
            <li class="divider"></li>
            <li><a href="#">...choices</a></li>
        </ul>
    </li>

Navbars

Syntax

navbar (inverse,) header => [ |link|, %navbar_has ],
             form => [
                 [ [ $url ], %form_has ],
                 [
                     formgroup => [ |formgroup| ],
                     input => [ |input| ],
                     button => [ |button| ],
                     submit_button => [ |submit_button| ],
                  ]
              ],
              button => [ |button| ],
              nav => [ |nav| ]
              p => [ $text, %p_has ]

Navbars are complex structures. They take the following arguments:

inverse

The inverse strapping is currently outside the %navbar_has. It applies the .navbar-inverse class.

header => [ |link|, %navbar_has ]

header creates a navbar-header. There can be only one header.

|link|

Creates the brand. Set the link text to undef if you don't want a brand.

%navbar_has

Can take the following extra arguments:

The hamburger strapping creates the menu button for collapsed navbars.

toggler => $collapse_id

This sets the id on the collapsing part of the navbar. Set it if you need to reference that part of the navbar, otherwise an id will be generated.

The following arguments can appear any number of times, and is rendered in order.

button => [ |button| ]

Creates a button.

nav => [ |nav| ]

Creates a nav. Use items if you need to create submenus.

p => [ $text, %p_has ]

Creates a <p>$text</p> tag.

form => [...]

Creates a form, by leveraging form_for in Mojolicious::Plugin::TagHelpers.

[ [ $url ], %form_has ]

Mandatory array reference. This sets up the form tag.

[...]

Mandatory array reference. The second argument to form can take different types (any number of times, rendered in order):

formgroup => [ |formgroup| ]

input => [ |input| ]

button => [ |button| ]

submit_button => [ |submit_button| ]

Creates form groups, input groups, buttons and submit_buttons

Examples

<%= navbar header => ['The brand', ['#'], hamburger, toggler => 'bs-example-navbar-collapse-2'],
           nav => [ items => [
                   ['Link', ['#'] ],
                   ['Another link', ['#'], active ],

            </ul>
        </div>
    </div>
</nav>

This is (almost) identical to the Bootstrap documentation example. The differences should be: The form has an action, the input has id and name.

Panels

Bootstrap documentation

Syntax

%= panel ($title, %has, begin
    $body
%  end)

$title

Usually mandatory, but can be omitted if there are no other arguments to the panel. Otherwise, if you don't want a title, set it undef.

$body

Optional (but panels are not much use without it). The html inside the panel.

Examples

%= panel

<div class="panel panel-default">
    <div class="panel-body">
    </div>
</div>

The class is set to .panel-default, by default.

%= panel undef ,=> begin
    <p>A short text.</p>
%  end

<div class="panel panel-default">
    <div class="panel-body">
        <p>A short text.</p>
    </div>
</div>

If you want a panel without title, set the title to undef.

%= panel 'The Header' => begin
    <p>A short text.</p>
%  end

<div class="panel panel-default">
    <div class="panel-heading">
        <h3 class="panel-title">The Header</h3>
    </div>
    <div class="panel-body">
        <p>A short text.</p>
    </div>
</div>


%= panel 'Panel 5', success, begin
    <p>A short text.</p>
%  end

<div class="panel panel-success">
    <div class="panel-heading">
        <h3 class="panel-title">Panel 5</h3>
    </div>
    <div class="panel-body">
        <p>A short text.</p>
    </div>
</div>

Tables

Bootstrap documentation

Syntax

%= table ($title,) %table_has, panel => { %panel_has }, begin
       $body
%  end

$title

Optional. If set the table will be wrapped in a panel, and the table replaces the body in the panel.

$body

Mandatory. thead, td and so on.

panel => { %panel_has }

Optional if the table has a $title, otherwise without use.

Examples

<%= table begin %>
    <tr><td>Table 1</td></tr>
<% end %>

<table class="table">
    <tr><td>Table 1</td></tr>
</table>

A basic table.

%= table hover, striped, condensed, begin
    <tr><td>Table 2</td></tr>
%  end

<table class="table table-condensed table-hover table-striped">
    <tr><td>Table 2</td></tr>
</table>

Several classes applied to the table.

%= table 'Heading Table 4', panel => { success }, condensed, id => 'the-table', begin
    <tr><td>Table 4</td></tr>
%  end

<div class="panel panel-success">
    <div class="panel-heading">
        <h3 class="panel-title">Heading Table 4</h3>
    </div>
    <table class="table table-condensed" id="the-table">
        <tr><td>Table 4</td></tr>
    </table>
</div>

A condensed table with an id wrapped in a success panel.

OPTIONS

Some options are available:

$app->plugin('BootstrapHelpers', {
    tag_prefix => 'bs',
    short_strappings_prefix => 'set',
    init_short_strappings => 1,
    icons => {
        class => 'glyphicon'
        formatter => 'glyphicon-%s',
    },
});

tag_prefix

Default: undef

If you want to you change the name of the tag helpers, by applying a prefix. These are not aliases; by setting a prefix the original names are no longer available. The following rules are used:

If the option is missing, or is undef, there is no prefix.
If the option is set to the empty string, the prefix is _. That is, panel is now used as _panel.
If the option is set to any other string, the prefix is that string. If you set tag_prefix => 'bs', then panel is now used as bspanel.

short_strappings_prefix

Default: undef

This is similar to tag_prefix, but is instead applied to the short form strappings. The same rules applies.

init_short_strappings

Default: 1

If you don't want the short form of strappings setup at all, set this option to a defined but false value.

All functionality is available, but instead of warning you must now use __warning => 1.

With short form turned off, sizes are still only supported in long form: __xsmall, __small, __medium and __large. The Bootstrap abbreviations (xs - lg) are not used.

icons

Default: not set

By setting these keys you activate the icon helper. You can pick any icon pack that sets one main class and one subclass to create an icon.

class

This is the main icon class. If you use the glyphicon pack, this should be set to 'glyphicon'.

formatter

This creates the specific icon class. If you use the glyphicon pack, this should be set to 'glyphicon-%s', where the '%s' will be replaced by the icon name you give the icon helper.
