Passing attributes in a jade mixin

问题

In older versions of jade you could pass the attributes of a mixin on to a block within it like so:

mixin a
    a(attributes=attributes)
        block

+a(href='foo')
    | Bar

however this now results in

<a attributes="[object Object]">Bar</a>

instead of

<a attributes="foo">Bar</a>

Other failed attempts to get this working are shown below. Does anyone know what the new syntax is?

Attempt 2

mixin a
    a(attributes)
        block

+a(href='foo')
    | Bar

Result:

<a attributes="attributes">Bar</a>

Attempt 3

mixin a
    a()(attributes)
        block

+a(href='foo')
    | Bar

Result:

<a attributes="attributes">Bar</a>

Attempt 4

mixin a
    a()(attributes=attributes)
        block

+a(href='foo')
    | Bar

Result:

<a attributes="[object Object]">Bar</a>

回答1:

It now looks like you use

mixin a
    a&attributes(attributes)
        block

+a(href='foo')
    | Bar

and https://github.com/visionmedia/jade/issues/1294 serves as the documentation.
