Is there a config flag to suppress the newline at the end of every ERB  
‘%\>’ tag, so it would not be necessary to type '-%\> each time?

You would include this line in your environment.rb file:

ActionView::Base.erb\_trim\_mode = ‘\>’

I’ve added this line and restarted the server. I get the following  
error:

* * *

## Rendering within layouts/users Rendering users/profile ERROR: compiling \_run\_html\_users\_profile RAISED compile error public/…/config/…/app/views/users/profile.rhtml:31: parse error, unexpected tSTRING\_BEG, expecting kDO\_COND or ‘:’ or ‘\n’ or ‘;’

Line 31 is the first line of ERB ending in a ‘%\>’ tag to be rendered by  
the controller:

30: \<% for @box in @boxes -%\>  
31: \<%= render :partial =\> ‘boxes/box\_line’ %\>  
32: \<% end -%\>

Now you have to delete all those ‘-’ characters throughout all your
