XHP classes for the Bootstrap project

Project Status

We are not planning to actively maintain this project; however, we still
believe it has value as an example.

XHP-Bootstrap was one of the first general-purpose UI libraries for XHP;
feedback from our users has shown several problems that ultimately make us
believe that general-purpose UI libraries are not a good fit for XHP:

Sites/applications should use semantic markup; Bootstrap should be an
implementation detail, not something that every endpoint/controller is
strongly tied to
Strict child validation is a valuable part of XHP; it’s not possible to
do take advantage of this in a general-purpose library. This can be
partially worked around through heavy usage of categories, however
that significantly weakens XHP’s model
A similar problem exists for attributes, however there is no workaround;
for example, many elements have an href attribute, which should take
a string in a general purpose library - many sites will want to ban
string hrefs, requiring a site-specific URI object instead. The only
way to support this would be to type all attributes as mixed

We believe this project is still useful for reference when implementing your
own elements. You may also find
the HHVM documentation site’s XHP elements useful as a real-world example.

Overview

The Bootstrap project is a popular HTML, CSS, and
JS framework providing common components for web pages. This project provides
XHP classes for these components.

Requirements

HHVM 3.6 or later
Composer

Getting Started

Step 1: Include Bootstrap Prerequisites

Bootstrap’s JavaScript components require
jQuery to be included, so either grab the
downloadable version and reference it, or
use a CDN and include it
in the head of your XHP document:

<head>
  ...
  <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
  ...
</head>

Step 2: Include Bootstrap Source

Grab the latest
Bootstrap package and
reference it, or use their
CDN links and include
them in the head of your XHP document:

<head>
  ...
  <!-- Latest compiled and minified CSS -->
  <link
    rel="stylesheet"
    href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css"
  />
  <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
  <!-- Latest compiled and minified JavaScript -->
  <script
    src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"
  ></script>
  ...
</head>

Step 3: Add XHP-bootstrap dependency

Add the following to your composer.json, then re-run composer:

  "minimum-stability": "dev",
  "require": {
    "hhvm/xhp-bootstrap": "dev-master"
  }

Step 4: Enable Composer Autoloading

If you haven’t already, include the following in your PHP to enable
autoloading from Composer:

  require_once('vendor/autoload.php');

Once you’ve done this you are ready to start using any of the XHP-Bootstrap
classes in your project.

Class References and Examples

You can also browse the list of available XHP-Bootstrap classes with live
examples at http://bootstrap.hhvm.com

You can also interact with these by configuring a webserver to look inside
the example/ directory and accessing example.php.

Differences

In the Bootstrap documentation, a component’s
default/primary/success/info/warning/danger/link state
(white/dark blue/green/light blue/orange/red/link) is referred to as use for
some components, but color for others. XHP-Bootstrap uses the use attribute
throughout for consistency.

XHP-Bootstrap is BSD-licensed. We also provide an additional patent grant.
