Lua File System or Equivalent

[Shando]

Hi All,

Just a quick request for an easy way to access files/folders on the Hard Drive.

I know that you already have some accessors, as I have seen

Code: Select all

sky.getDir_Models()

in the Scatter Plugin

Basically, I would like:

1) a way to access a directory in the final .exe directory (my own, or the "Script" directory)
2) a way to get all files in a specified directory that contain a specific suffix (such as .lua)

Thanks

Shando

EDIT: I think I've found a way to handle 2) above:

Code: Select all

function get_files ( path, prepend_path_to_filenames )
   if path:sub(-1) ~= '\\' then
      path = path .. '\\';
   end

   local pipe = io.popen ( 'dir /b/a-d "' .. path .. '*.*" 2> nul' );
   local output = pipe:read'*a';

   pipe:close();

   -- If your file names contain national characters
   -- output = convert_OEM_to_ANSI(output)
   local files = { };

   for filename in output:gmatch'[^\r\n]+' do
      if prepend_path_to_filenames then
         filename = path .. filename;
      end

      -- ONLY SAVE ".cha" FILES
      if ( string.sub ( filename, -4, -1 ) == ".cha" ) then
         table.insert ( files, filename );
      end
   end

   return files;
end


To use, you need something like:

Code: Select all

-- need to change this next line depending on how we access folders in Skyline:
local array_of_files = get_files ( 'D:\\Aurasoft\\SkylineSDK', false )

for _, fn in ipairs ( array_of_files ) do
   sky.lprint ( fn );
end


I found this on Stack Overflow (http://stackoverflow.com/questions/13665333/extracting-file-data-with-lua - in a response by Egor Skriptunoff), just not sure if it will work in a final game??

Nice workarounds m8.

It would not be too diffuicult to add all the directory finding and file finding tools.
We have a lot of written out code in the main skyline codebase anyway.
If i remember, i will try and get this up and running.
