similar to: Ruby++ FFI (theoretical)

I wanted to group some functions which I use in some models in one place. Controllers have application.rb and views have helpers but I couldn''t find anything about models. Using the /lib directory seemed to be the only way. Alright... so I have something like this: /lib/code.rb class ActiveRecord::Base def method_a(n) ....... end def method_b(n) ........ end end

SystemStackError in GreyController#grey_search stack level too deep can anybody please enlighten me on this one...any possible way to troubleshoot? thanks, MSN id: ICEMANyears@netscape.net -- Posted via http://www.ruby-forum.com/.

Hi, I have two model: Message, User message.rb ``` class Message < ActiveRecord::Base class << self def method_a(args) [1,2] end end end ``` user.rb ``` class User < ActiveRecord::Base def method_user if Message.method_a(''anythings'') #... some code end end end ``` I want to test method_user,but I don''t want to test

Hi all, I feel like I''m missing something really easy and I''m just not seeing it. I''m using the restful_authentication plugin and have a User model. Uesr has_many :things and Thing belongs_to :user. That''s it. I did a "script/generate rspec_scaffold thing" to generate all the necessary bits. The "rake db:migrate" to create the db. At

I looked around for the status of OrcJIT FFI support. The last e-mail thread I could find was this one: Link <http://lists.llvm.org/pipermail/llvm-dev/2015-February/081679.html> Raw: http://lists.llvm.org/pipermail/llvm-dev/2015-February/081679.html Is OrcJIT now considered stable enough that there can be "official" exposed C APIs? If not, what's the standard approach if I

Hi all, Any Java/JRuby folks on the list? I''d like to see if we can implement api.c for JRuby using JNA and see how it handles the callbacks. I''m not a Java guy, nor do I know JNA, but I''ll take a stab at it if no one else on the list does. Here are a couple of useful links: http://www.infoq.com/news/2007/09/jna-jruby https://jna.dev.java.net/ Regards, Dan This

You're right, that probably won't have very good performance. What we (unladen-swallow) do is to call getPointerToFunction which gives a function pointer of type (void*)(void*) which we then cast to the appropriate function type and then call from C/C++. That way the C/C++ compiler for your application can codegen the function call once instead having the JIT do it many times. Reid On

While browsing the configure generated llvm/Config/config.h, I'm noticed that the macros: HAVE_FFI_CALL HAVE_FFI_FFI_H HAVE_FFI_H are not defined on OS X (currently 10.6.5). Given that ffi exists on this platform (both headers and lib), is this result intended? Thanks Garrison

Ah, --enable-libffi. Any pointers as why this is not a default check for at least UNIX systems? Does Windows have the equivalent?

I'm getting a segfault when I call `SDL_Init( SDL_INIT_VIDEO )` within the MCJIT.  If I compile the same program to an EXE I don't have a problem. Are there any general restrictions, or known issues, with loading a library like SDL2 via the MCJIT?  (LLVM-3.8 still) The stack trace, from GDB, is below. I noticed the error actually happens deep inside a transitively loaded GL drive module,

Hello, I'm new to LLVM and I had a question about it: when we call the JIT::runFunction, since llvm doesn't has a full FFI, there are some cases in which the JIT needs to codegen a stub function to call the function we are interested, my question is: this stub function will remains in the module until when ? What are the most efficient way to remove it from the module and memory ? For a

Hi, I''ve been using FFI with a Ruby 1.9.3 built with MSVC++ and it''s been working well. One thing I''ve run into though is this: ffi_lib :msvcrt But that''s not the runtime I want. But I don''t want to hard code the runtime name either. I realize I could parse it out of RbConfig, but I was hoping for something nicer. Is there a way we could create an

Hi, Try as I might, I just cannot get Dir.create_junction to work with FFI in the ffi branch of the win32-dir project. The problem is the REPARSE_JDATA_BUFFER struct. I''m just not sure how to set those members, specifically, the PathBuffer member. The target looks good, it''s UTF-16LE encoded, but I can''t make it work, despite trying several ways of defining the struct,

Hi Folks, Just a quick message saying that, after much demand, I wrote a quick write-up for the RoR + XUL thing I did yesterday: http://www.zedshaw.com/blog/programming/ruby_xul.html It lays out the few simple things I did, has a bit of rant on an unrelated topic, and other stuff but it''s short still. On a related note, I''d like to thank "xal" on IRC for reminding
