This project was formerly known as "Jade." However, it has been revealed to us that "Jade" is a registered trademark, and as a result a rename is needed. After some discussion among the maintainers, **"Pug"** has been chosen as the new name for this project. The next major version will carry "pug" as the package name.
If your package or app currently uses `jade`, don't worry: we have secured permissions to continue to occupy that package name, although all new versions will be released under `pug`.
Before the renaming, we had already begun working on an incompatible Jade 2.0.0. We have then made it so that this new major version bump will coincide with the rename to Pug. Therefore, upgrading from Jade to Pug will be the same process as upgrading any other package with a major version bump. Currently, Pug 2.0.0 is still under beta stage, and there are several syntactic differences we have deprecated and removed. Such differences are documented at [#2305](https://github.com/pugjs/pug/issues/2305).
The website and documentation for Pug are still being updated, but if you are new to Pug, you should get started with the new syntax and install the Pug package on npm.
## Installation

```bash
$ npm install pug
```

## Syntax
Pug is a clean, whitespace sensitive syntax for writing html. Here is a simple example:
```pug
doctype html
html(lang="en")
head
title= pageTitle
script(type='text/javascript').
if (foo) bar(1 + 5)
body
h1 Pug - node template engine
#container.col
if youAreUsingPug
p You are amazing
else
p Get on it!
p.
Pug is a terse and simple templating language with a
strong focus on performance and powerful features.
```
becomes
```html
<!DOCTYPE html>
<htmllang="en">
<head>
<title>Pug</title>
<scripttype="text/javascript">
if (foo) bar(1 + 5)
</script>
</head>
<body>
<h1>Pug - node template engine</h1>
<divid="container"class="col">
<p>You are amazing</p>
<p>Pug is a terse and simple templating language with a strong focus on performance and powerful features.</p>
</div>
</body>
</html>
```
## API
For full API, see [pugjs.org/api/reference.html](https://pugjs.org/api/reference.html)
```js
var pug = require('pug');
// compile
var fn = pug.compile('string of pug', options);
var html = fn(locals);
// render
var html = pug.render('string of pug', merge(options, locals));
// renderFile
var html = pug.renderFile('filename.pug', merge(options, locals));
```
### Options
-`filename` Used in exceptions, and required when using includes
-`compileDebug` When `false` no debug instrumentation is compiled
-`pretty` Add pretty-indentation whitespace to output _(false by default)_
## Browser Support
The latest version of pug can be download for the browser in standalone form from [here](https://pugjs.org/js/pug.js). It only supports the very latest browsers though, and is a large file. It is recommended that you pre-compile your pug templates to JavaScript.
To compile a template for use on the client using the command line, do:
```bash
$ pug --client --no-debug filename.pug
```
which will produce `filename.js` containing the compiled template.
