I'd like to remove space after name and accomplish final HTML to this effect using HAML: John, CEO
%p.about_title_bx
= truncate about.name,length:100
, #{truncate about.position,length:100}
You can add an < in order to remove the whitespace:
%p.about_title_bx<
= truncate about.name,length:100
, #{truncate about.position,length:100}
See Whitespace Removal: > and <
Also, remember that HAML is supposed to help with structure, not content. Having a helper method or having that content inline might be a better solution.
