Someone must write a grammar that racc uses to generate a parser. You are seeing an error with the grammar file, not with Racc. What gem are you using where you see this error? Can we get a larger stack trace? ---

It comes from flog via ruby-parser (flay gives the same error): F:/Ruby19/lib/ruby/gems/1.9.1/gems/racc-1.4.6/lib/racc/parser.rb:347:in `on_error': (Racc::ParseError) parse error on value "in" (kIN) from F:/Ruby19/lib/ruby/gems/1.9.1/gems/racc-1.4.6/lib/racc/parser.rb:99:in`\_racc\_do\_parse\_c’ from F:/Ruby19/lib/ruby/gems/1.9.1/gems/racc-1.4.6/lib/racc/parser.rb:99:in `do_parse' from F:/Ruby19/lib/ruby/gems/1.9.1/gems/ruby_parser-2.0.4/lib/ruby_parser_extras.rb:749:in`process’ from F:/Ruby19/lib/ruby/gems/1.9.1/gems/flog-2.4.0/lib/flog.rb:176:in `block in flog' from F:/Ruby19/lib/ruby/gems/1.9.1/gems/flog-2.4.0/lib/flog.rb:170:in`each’ from F:/Ruby19/lib/ruby/gems/1.9.1/gems/flog-2.4.0/lib/flog.rb:170:in `flog' from F:/Ruby19/lib/ruby/gems/1.9.1/gems/flog-2.4.0/bin/flog:11:in`\’ from F:/Ruby19/bin/flog:19:in `load' from F:/Ruby19/bin/flog:19:in`’ Of course, ‘in’ is also a keyword. When using a key which is not a keyword, the error happens when parsing the colon. ---

But what about flog ? Should we just forget it ? Flog and flay both use ruby\_parser to do their work. So far I haven’t had any motivation to get ruby\_parser working with 1.9’s syntax changes. I am bribable tho. 😃 ---

I am bribable tho. 😃 The funny fact is that I changed the syntax in my project to please Saikuro ! There is a saying in French “you cannot please everybody and your wife !”. M. ---

A simple preliminary rake task passing files through gsub!(/(\w+):\s+/, ‘\1 =\>’) solves the problem. It is easier than changing ruby\_parser… Actually, it is quite strange/funny to be able to write hashes like if: true, raise: SyntaxError M.
