file exists

GregBUG

is there a better way for check if a file exists in lua ? :-B

-------------------------- -- check if file exists -- -------------------------- local function fileExists(fileName) local file = io.open(fileName) if file ~= nil then io.close(file) end return file == nil end

thanks.

Hi Gianluca,

I don't know a better way then yours. On the other hand LuaFileSystem plugin http://keplerproject.github.com/luafilesystem/ is on the roadmap http://bugs.giderosmobile.com/issues/58

thanks @atilim!.

you can try using pcall, just in case lua throws an error and it breaks the app and you can also know if the function succeeded or not (which would be the same as if the file existed or not)

you are welcome, Lua with just 35 OP Codes is so vast and flexible, that it is just amazing...
