Srlua packed executables need to locate the executable at runtime in order to read the embedded script in it. In the vanilla implementation this was done using some guesses and arg[0] parsing. Things get ugly when srlua executables are called from PATH so that arg[0] containes insufficient information to find the executable location. Therefore I have been forced to patch[1] the srlua implementation to use system specific means to do it. This makes srlua apps behave correctly even when placed into PATH. The code is identical to the code used in LuaDist Lua for relative LUA_PATH/LUA_CPATH handling on OSes other than Windows[2]. pd [1] https://github.com/LuaDist/srlua/commit/921337b30f7203585647a3b27cb9f59ce99dad51 [2] https://github.com/LuaDist/lua/blob/master/src/loadlib_rel.c#L140 ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
