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-address', prepend => '@'], large
# ...that renders into
<div class="form-group form-group-lg">
<label class="control-label" for="email-address">Email</label>
<div class="input-group">
<span class="input-group-addon">@</span>
<input class="form-control" id="email-address" name="email_address" 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: 3.2.0.
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-theme.min.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.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
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[] An array reference (ordering significant)
%name A hash (ordering not significant)
$name{} A hash reference (ordering not significant)
Panels
Syntax
%= panel
%= panel $title, %strappings, 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
.
%strappings
Optional hash. Any strapping you want applied to the panel
.
$body
Optional (but panels are not much use without it). The html inside the panel
.
Examples
No body, no title
%= panel
<div class="panel panel-default">
<div class="panel-body">
</div>
</div>
The class is set to panel-default
, by default.
Body, no title
%= 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
. Note that you can't use a regular fat comma since that would turn undef into a string. A normal comma is of course also ok.
Body and title
%= 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>
Body and title, with context
%= 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>
Here, the success
strapping applies .panel-success
to the panel.
Form groups
Syntax
%= formgroup $labeltext, %arguments
%= formgroup %arguments, begin
$labeltext
% end
# %arguments:
cols => { $size => [ $label_columns, $input_columns ], ... },
%strappings
$fieldtype => $field_setting[],
# $field_setting[]
$name,
$value,
%field_arguments
# %field_arguments
%html_attributes,
%prepend,
%append,
%strappings
$labeltext
Mandatory. It is either the first argument, or placed in the body.
%arguments
Mandatory. A hash:
cols
Optional hash reference. It is only used when the form
is a .form-horizontal
. $size
is one of xsmall
, small
, medium
, or large
. $size
takes a two item array reference: $label_columns
is the number of columns that should be used by the label for that size, and $input_columns
is the number of columns used for the input field for that size.
You can defined the widths for one or more or all of the sizes.
%strappings
Optional hash. One or more strappings you want applied to the .form-group
element.
$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
. (Behavior if having more than one is not defined.)
$field_setting[]
Mandatory. An array reference:
$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 $field_arguments{'id'}
exists then that is used for the id
instead.
$value
Optional. It is the same as setting $field_arguments{'value'}
. (But don't do both for the same field.)
%field_arguments
Optional. A hash:
%html_attributes
Optional. All html attributes you want to set on the input
.
%prepend
and %append
Optional. Can be used individually or together. They are used to create input groups.
%strappings
Optional. All strappings you want applied to the input
.
Examples
Basic form group
%= formgroup 'Text test 1', text_field => ['test_text']
<div class="form-group">
<label class="control-label" for="test_text">Text test 1</label>
<input class="form-control" id="test_text" name="test_text" type="text" />
</div>
The first item in the array ref is used for both id
and name
. Except...
Input group (before), and large input field
%= formgroup 'Text test 4', text_field => ['test-text', append => '.00', large]
<div class="form-group">
<label class="control-label" for="test_text">Text test 4</label>
<div class="input-group">
<input class="form-control input-lg" id="test-text" name="test_text" type="text" />
<span class="input-group-addon">.00</span>
</div>
</div>
Strappings can also be used in this context. Here large
applies .input-lg
.
If the input name (the first item in the text_field array ref) contains dashes, those are replaced (in the name
) to underscores.
Input group (before and after), and with value
%= formgroup 'Text test 5', text_field => ['test_text', '200', prepend => '$', append => '.00']
<div class="form-group">
<label class="control-label" for="test_text">Text test 5</label>
<div class="input-group">
<span class="input-group-addon">$</span>
<input class="form-control" id="test_text" name="test_text" type="text" value="200" />
<span class="input-group-addon">.00</span>
</div>
</div>
Here, the second item in the text_field
array reference is a value that populates the input
.
Large input group
%= formgroup 'Text test 6', text_field => ['test_text'], large
<div class="form-group form-group-lg">
<label class="control-label" for="test_text">Text test 6</label>
<input class="form-control" id="test_text" name="test_text" type="text" />
</div>
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.
Horizontal form groups
%= 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>
If the form
is .form-horizontal
, you can set the column widths with the cols
attribute. The first item in each array ref is for the label, and the second for the input.
(Note that in this context, medium
and large
are not short form strappings. Those don't take arguments.)
Buttons
Syntax
%= button $button_text, $url[], %arguments
# %arguments
%html_attributes,
%strappings
$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.
%arguments
Optional hash.
%html_attributes
Optional hash of any html attributes you want to set on the button/link.
%strappings
Optional hash. Any strappings you want to set on the button/link.
Examples
%= button 'The example 5' => large, warning
<button class="btn btn-lg btn-warning">The example 5</button>
An ordinary button, with applied strappings.
%= button 'The example 1' => ['http://www.example.com/'], small
<a class="btn btn-sm" href="http://www.example.com/">The example 1</a>
With a url the button turns into a link.
Tables
Syntax
%= table $title, %arguments, begin
$body
% end
# %arguments
%strappings
panel => $strappings{}
$title
Optional. If set the table will be wrapped in a panel. The table replaces the body.
%arguments
Optional hash:
%strappings
Optional. A hash of the strappings to apply to the table.
panel => $strappings{}
An optional key-value pair. $strappings{} is hash reference containing any strapping you want to set on the panel.
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, 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">
<tr><td>Table 4</td></tr>
</table>
</div>
A condensed
table wrapped in a success
panel.
OPTIONS
Some options are available:
$app->plugin('BootstrapHelpers', {
tag_prefix => 'bs',
short_strappings_prefix => 'set',
init_short_strappings => 1,
});
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 followed by
_
. If you settag_prefix => 'bs'
, thenpanel
is now used asbs_panel
.
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.
