In Rails, both the javascript_tag and javascript_include_tag render the type attribute as

type="text/javascript"

I need to customize this attribute. Our application uses Slim syntax which makes this a little more difficult.

script src="mathjax_config" type="text/x-mathjax-config"

^ doesn't error but doesn't even include the file

javascript_tag[type="text/x-mathjax-config"] javascript code here

^ throws an error

I'm hoping to avoid breaking the file away from slim.

Ruby version 1.9.3 Rails version 3.2.3

Since you are modifying the type attribute you would either need to override the javascript_tag helper or write your own for that to work. This syntax isn't as elegant but should work:

script src=asset_path("mathjax_config") type="text/x-mathjax-config"

Note that this is slim/haml syntax - YMMV in erb.

The file not being included is not Slims fault. Slim is agnostic to the content of the attributes, so it will happily render 

script src="mathjax_config" type="text/x-mathjax-config"

into

<script src="mathjax_config" type="text/x-mathjax-config"></script>

Also, as far as I know, the browsers should happily load scripts with types other than "text/javascript" and you should be able to access them using their id.

Your approach is correct and the script not being included must have a different reason (like the file specified in src cannot be found).
