其他属性:

a(href="google.com") google

- var attr = {}
- attr.class = "baz"
div(data-bar="foo")&attributes(attr)
        

编译结果:

<p class="authed"></p>
<input type="checkbox" name="agreement" checked>
<div data-bar="foo" data-foo="bar"></div>

<div class="baz" data-bar="foo"></div>

注释

// 行注释
//- 编译后不会显示出来
//
  块注释
<!--可以直接使用注释代码-->

case语句

- var num = 3
case num
  when 0
    p 这是0
  when 1 
    - break
  when 3
    p 这是#{num}

编译结果:

<p>这是3</p>

循环

ul
  - var n = 0
  while n < 4
    li= n++
 ul
  - for (var x = 0; x < 3; x++)
    li item
ol
  - var list = [1,2,3,4,5,6]
  each item in list
    li= item

编译结果:

<ul>
  <li>0</li>
  <li>1</li>
  <li>2</li>
  <li>3</li>
</ul>
<ul>
  <li>item</li>
  <li>item</li>
  <li>item</li>
</ul>
<ol>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
  <li>6</li>
</ol>

条件语句

- var user = {foo: "this is foo"}
- var bar = baz
#user
  if user.foo
    h2.green foo
    p.foo= user.foo
  else if bar
    h2.blue foo
    p.foo.
      User has no foo
  else
    h2.red foo
    p.foo user has no foo

unless user.isFoo
  p 等同于:if !user.Foo

编译结果:

<div id="user">
  <h2 class="green">foo</h2>
  <p class="foo">this is foo</p>
  <p>等同于:if !user.Foo</p>
</div>

mixin 创建重用的代码

mixin list
  ul
    li foo
    li bar 
    li baz
+list
+list

编译以后:

<ul>
  <li>foo</li>
  <li>bar </li>
  <li>baz</li>
</ul>
<ul>
  <li>foo</li>
  <li>bar </li>
  <li>baz</li>
</ul>

mixin支持传参

mixin article(title)
  .article
    .article-wrapper
      h3= title
      if block
        block
      else
        p NO content provided
+article("Hello worle")
+article("hello pug")
  p This is my
  p Amazing article

编译结果:

<div class="article">
  <div class="article-wrapper">
    <h3>Hello worle</h3>
    <p>NO content provided</p>
  </div>
</div>
<div class="article">
  <div class="article-wrapper">
    <h3>hello pug</h3>
    <p>This is my</p>
    <p>Amazing article</p>
  </div>
</div>

还有:

mixin link(href, name)
  a(class!=attributes.class href=href)= name
+link("/foo", "foo")(class="btn")

编译结果:

<a class="btn" href="/foo">foo</a>

未知参数:

mixin list(id, ...items)
  ul(id=id)
    each item in items
      li= item
+list("my-list",1,2,3,4)

编译结果:

<ul id="my-list">
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
</ul>
