# UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
# just run "sudo trimforce enable" to activate the trim support from now on!

# Original version by Grant Parnell is offline (http://digitaldj.net/2011/07/21/trim-enabler-for-lion/)
# Update July 2014: no longer offline, see https://digitaldj.net/blog/2011/11/17/trim-enabler-for-os-x-lion-mountain-lion-mavericks/

The state of MessagePack in Lua

The new MessagePack website says that MessagePack for Lua is "coming soon". I thought it would be a good idea to make a quick recap on the state of MessagePack in Lua.

The historical implementation of MessagePack is mplua by Nobuyuki Kubota. It is the implementation linked from the MessagePack wiki. However, it is rather old (no updates for two years) and not very fast.

A bit less than a year ago I had to use MessagePack in LuaJIT and I wrote a FFI-based binding on the official C interface of MessagePack. I had to include a small C library that had to be compiled to wrap inline functions in the interface.

I did not like that design and it had performance issues in real use cases, mostly because I had to use calls that break the JIT mode in LuaJIT. I decided to re-implement MessagePack directly in LuaJIT with no calls to any
