The following script takes the name of a template as it's argument. Within the
template the command erb is in scope to call more templates. I wrote this for a friend who was having hell with NVU templates and I suggested to write the code by hand and use this script to build his static pages.
The erb command itself takes an optional argument of a hash which is passed to the template as the
variable name args. Thus you can parameterize your sub templates.
Call the command as
The main template
and the sub template title.thtml

Call the command as
ruby erb_run.rb main.thtml
The main template
<html> <head> </head> <div> <%= erb("title.thtml") %> </div> </html>
and the sub template title.thtml
