mruby-clang-plugin

clang plugin to check mruby C API call that could be unsafe.

Howto use

Add following line to build_config.rb:

  conf.gem :github => 'take-cheeze/mruby-clang-plugin'

What it checks

  • wrong use of variadic mruby C API such as mrb_get_args, mrb_raisef, mrb_funcall etc.
  • 2nd argument of mrb_intern_cstr which is string literals. mrb_intern_lit is preferred in that case.

Where it works

I've tested it on OS X Mavericks and Debian with clang-3.3. It isn't tested in C++ code so please create an issue about it when you get wrong behavior.
