Rails and embedded ruby

For my website I have the following title helper:

<% provide(:title, 'My Page') %>

Which produces something like this:

enter image description here

Instead of the generic 'My Page' I'm trying to add the user name, for instance 'mtcrts70'. To do this I tried the following code:

<% provide(:title, '<%= current_user.email[/[^@]+/] %>') %>

Note that <%= current_user.email[/[^@]+/] %> renders perfectly when outside of the <% %> tags.

It seems like the issue is putting <%= %> inside of <% %>. Is there a way to get around this?

Error message:

SyntaxError in Static_pages#home

What's inside <% %> is a piece of normal Ruby code. You just need to pass in the value as argument to the provide helper method. 

<% provide(:title, current_user.email[/[^@]+/]) %>
