NameError (uninitialized class variable @@hide_format in #Class:0x00000006debf88):
grape-swagger (0.6.0) lib/grape-swagger.rb:68:in `block (2 levels) in setup'

i'm using mruby 1.9.2-p290, i dont know whether this will work on higher version, but simply i dont think initialize a class variable in Class.new(Grape::API) can be reached in helpers do(which means Module.new)

This is old, I am going to close this. @Jokery did you ever resolve this? Please reopen if this is still an issue on newer versions of the gems.

@tian-xiaobo You're using grape-swagger 0.7.2, which doesn't support grape 0.10.1, upgrade to the latest, 0.9.0.
