I'm getting this warning: .../Bundle Support.tmbundle/Support/shared/lib/tm/htmloutput.rb:91: warning: Invalid ERB trim mode: "%-<>" (trim_mode: nil, 0, 1, 2, or String composed of '%' and/or '-', '>', '<>') When I look at that line, I see: ERB.new(HTMLOUTPUT_TEMPLATE, 0, '%-<>').result(binding) My guess is that the warning is a consequence of this change: https://redmine.ruby-lang.org/issues/15294 My guess is that '%-' is intended (experimentation shows that it is valid and works). I suspect this was always invalid but the issue was ignored. m. -- matt neuburg, phd = http://www.apeth.net/matt/ pantes anthropoi tou eidenai oregontai phusei Programming iOS 12! http://shop.oreilly.com/product/0636920208662.do iOS 12 Fundamentals! http://shop.oreilly.com/product/0636920208655.do RubyFrontier! http://www.apeth.com/RubyFrontierDocs/default.html
