We don’t care about the trim mode as nobody is reading the generated HTML, but we have to supply something, previously we enabled everything, which is now giving an error despite the documentation saying that trim mode can be “one or more of the following modifiers”: % enables Ruby code processing for lines beginning with % <> omit newline for lines starting with <% and ending in %> > omit newline for lines ending in %> - omit blank lines ending in -%> It would seem that ‘<>’ is mutually exclusive with ‘-’ so now we pass ‘%-’ for trim mode.
