# Pug



Full documentation is at [pugjs.org](https://pugjs.org/)



Pug is a high-performance template engine heavily influenced by [Haml](http://haml.info/)

and implemented with JavaScript for [Node.js](http://nodejs.org) and browsers. For bug reports,

feature requests and questions, [open an issue](https://github.com/pugjs/pug/issues/new).

For discussion join the [chat room](https://gitter.im/pugjs/pug).



You can test drive Pug online [here](https://pugjs.org/).

## Rename from "Jade"



This project was formerly known as "Jade". However, it was revealed to us that "Jade" is a registered trademark; as a result, a rename was needed. After some discussion among the maintainers, **"Pug"** was chosen as the new name for this project. As of version 2, "pug" is the official 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, work had already begun on “Jade 2.0.0”. Therefore, the rename to Pug coincided with the major version bump. As a result, upgrading from Jade to Pug will be the same process as upgrading any other package with a major version bump.



The syntax of Pug has several differences, deprecations, and removals compared to its predecessor. These differences are documented in [#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 from npm.



## Installation



### Package



To use Pug in your own JavaScript projects:



```bash

$ npm install pug

```



### Command Line



After installing the latest version of [Node.js](http://nodejs.org), install with:



```bash

$ npm install pug-cli -g

```



and run with



```bash

$ pug --help

```



## 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.

```



Pug transforms the above to:



```html



  

    Pug

    

      if (foo) bar(1 + 5);

    

  

  

    
Pug - node template engine


    


      
You are amazing


      


        Pug is a terse and simple templating language with a strong focus on

        performance and powerful features.

      


    


  



```



## 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 [downloaded for the browser in standalone form](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.
