Ilya Maykov commented on THRIFT-1204:
-------------------------------------

Fair enough, I buy the argument that rubygems shouldn't be forced on all users 
by auto-generated code. I'll think about a clean way to parameterize the 
behavior and post my proposal here in a day or two.

I'm not sure about doing the (gem "thrift", "= 0.6.0") thing, for one it would 
prevent people from using a forked / modified gem with a different version 
number with their stubs. And it would cause needless recompiles of gen-rb files 
between gem versions, even if they are in fact compatible (i.e. if the ruby 
generated code doesn't change between 0.6.0 and 0.7.0 then it's fine to use 
0.6.0-compiled stubs with a 0.7.0 gem).

I like the idea in spirit, perhaps we could have some other version number - 
maybe call it something like RUBY_API_VERSION - that's incremented when the 
compiler changes. And we could make the stubs file check that its 
RUBY_API_VERSION matches the one in the loaded thrift gem / library.

> The gen-rb files currently don't require the thrift gem. This means that the 
> user of such a file must explicitly require 'thrift' in his code before 
> requiring a gen-rb file, which can be a bit annoying (especially when 
> debugging / experimenting in IRB). I propose that we change the compiler to 
> add the require at the top of every gen-rb file.
> Patch coming shortly.
