  div {
    class 'modal';

    div {
      class 'modal-dialog';

      div {
        class 'modal-header';
        h5 { class 'modal-title'; text 'Modal title' };
        button { class 'close'; attr 'type' => 'button', 'data-dismiss' => 'modal'; raw '×'; };
      };

      div { class 'modal-body'; raw $content; };

      div {
        class 'modal-footer';
        button { class 'btn btn-primary'; attr 'type' => 'button'; text 'Save changes'; };

#         Close
#       </button>
#     </div>

DESCRIPTION

This is adapted from a series of short scripts I had written for use in vim. I figured someone else might find them useful so I cleaned them up a bit and spent the rest of the afternoon trying to figure out what the hell to call it.

NAME

HTML::Untidy

PURPOSE

Sometimes I don't want to have a proper separation of concerns. Sometimes I just want to generate HTML programmatically and easily from perl because I hate writing HTML or I want to build a page from componentized parts.

Isn't this just CGI::HTML::Functions? Yeah, kinda. But so are React and Vue. Complain and maybe I'll write Inline::HTML.

I think I got all of the HTML5 tags added. If there are any I missed, it's simple enough to add your own.

*blink   = sub(&){ unshift @_, 'blink';   goto \&element; });
*marquee = sub(&){ unshift @_, 'marquee'; goto \&element; });

EXPORTED SUBROUTINES

:base

Base functions everything else is built from.

element

Accepts a tag name and subroutine to generate its components. In scalar context, returns a formatted string of HTML. In void context within another call to element, the generated string is appended to the parent element.

class

Accepts a list of strings to use as the class list for the element. Multiple classes may share the same string, separated by whitespace. No deduplication is done on these.

attr

Takes key/value pairs as a hash and generates attributes. Again, no deduplication, and the attributes are displayed in the order in which they are passed.

prop

Adds a property which has no value (e.g. disabled or hidden).

text

Adds escaped text to the body of the tag.

raw

Adds unescaped text to the body of the tag.

note

Adds an HTML comment to the body of the tag.

indentation

If you want indentation, set $HTML::Untidy::INDENT to the number of spaces you want per level.

local $HTML::Untidy::INDENT = 2;

element 'div', sub{
  element 'button', sub{
    class 'btn btn-primary';
    attr id => 'some-button', 'data-toggle' => 'modal', 'data-target' => 'my-modal-id';

    if ($some_condition) {
      text 'Click me';
    }
    else {
      prop 'disabled' if $some_condition;
      text "Don't click me";
    }
  };
};

:common

Exports the following curried aliases of "element" for the most commonly used HTML tags.

html head body title meta link script style h1 h2 h3 h4 h5 h6 div p hr pre nav
code img a b i u em strong sup sub small table tbody thead tr th td ul dl ol
li dd dt form input textarea select option button label canvas
