[Torch5-devel] luaT & MapStorage & SVN

[Ronan C. <ro...@co...>]

Hi,

*** LuaT

   I made major changes in luaT, such that it handles better class  
inheritance.

   From the Lua side, this has little impact.

   From the C side, few functions changed. In particular  
luaT_newmetatable() now takes
      * a string for the name of the class
      * a string for the parent class (or NULL) (this was previously  
an id)
      * a constructor (or NULL)
      * a destructor (or NULL)
      * a factory (or NULL)
   Once a constructor/destructor or factory is set, it cannot be  
changed, avoiding messing up from Lua. Also, the true metatable is  
hidden from Lua now, you can see only the metatable containing  
methods (so you cannot messup constructor or __gc from there).

   New feature: all functions of a class can now be accessed in the  
following way: torch.Tensor.fill(x, 1) instead of x:fill(1).

*** MapStorage

   As several people seemed interested in it, I added MapStorage in  
torch module. It works on the platforms we support.
   x = torch.DoubleMapStorage(filename) returns a kind of  
DoubleStorage which maps the contents of a file in memory.

*** SVN

   The website has been updated. Now Torch should be officially  
retrieved from SVN.
