Multiple Haml Elements on Same Line

问题

I want to be able to have two Haml elements on the same line. For example:

%h1 %a{:href => '/'} Professio.

That doesn't work. How would I get something like this to work without borking?

回答1:

Unfortunately, you cannot put two haml elements on the same line.

You can achieve something similar by using inline html elements:

%h1 <a href='/'>Lorem ipsum</a>

Why don't you like this format?

%h1 
  %a{:href => '/'} Professio.

Another option is to write special 'helper' method (that generate an html link). For example, the link_to in Rails:

%h1= link_to 'Professio', root_url

Late answer, but I was just tackling the same problem myself and knew HAML had a way to do this as part of the language. See the White Space Removal section of the HAML reference.

You could do it this way:

%h1<
  %a{ :href => '/' } Professio.

Or this way:

%h1
  %a{ :href => '/' }> Professio.

Haml cannot do this. Slim can:

h1: a( href='/' ) Professio.

is the same as:

h1
  a( href="/ ) Professio

You can write as deeper tree as you need:

ul.nav
  li.active: a( href="/home" ):    strong Home
  li:        a( href="/contact" ): span   Contact

Jade also has similar syntax and support this feature, but it's been designed for Node.js environment.

If you're looking to preserve the HTML on the same line you could try something like this:

irb> print Haml::Engine.new("%h1<\n  %a{:href => '/'} Profession.").render()
<h1><b href='/'>Profession.</a></h1>

[Edit: I know that's says b href above...]
