Re: SLB vs LuaBind

[liam mail <liam.list@...>]

I don't really have anything broken out in a way I can share; it was
parts of my library, wrapped, so that it was as "real" of a benchmark
for me as possible.

Tim, no problem it would not be difficult to create a test case I just though it would be nice to use the same examples as you did.

Jose profiling, looking at the generated assembly just the same techniques you would use on any other code; yet with the addition of only touching the Lua API when you must. I do use a simple speed comparison test[1] and there are more detailed results available[2]. Daniel Wallin did say that Luabind has a comparison test for other libraries yet IIRC due to dependancies he is unable to make it available.

I have attempted to look at SLB a few times and some things put me off from even comparing it with OOLua, mostly the use of a dreaded singleton which I am not sure how it effects unrelated Lua states and see it will only close onexit. Then there is the unit tests which I like to consider as the documentation, if you do not mind I would like to suggest you rename the tests. For example as a none user of the library what actually is unit_00X.cpp (replace X with a number) testing, which script does it load? Maybe look at using a C++ or Lua testing framework, 

personally I like to see setup, operation, assert, teardown. OOLua did in the past did load external scripts and run tests yet it 

separated the code too much so instead it use strings for the Lua code to try and help ease the reading of the test units, although 

saying that I sometimes generate the Lua code which makes reading slightly harder.

Beo I could not disagree more. These "samples" should be the unit tests which get run all the time and are always correct. Do the SLB examples get run by Jose? I have no idea and they could be wrong which is much worse than having no examples, personally I do not think the Luabind samples or it's unit tests are anything to shout about.
