Why scripts are not working properly in fusion 8 , as these are working fine in version 7 or previous.
i am using


readdir("d:\\*.*")


this is not working. not reading the folders in fusion 8.
plzzzz help me.

Hi. The readdir command comes from the addon lua-fs library that is not available with the version of Lua that is included in Fusion 8.

You will have to re-write your Fusion 7 based Lua code to work around this limitation to make the script work in the current Fusion 8.2 release.

At the same time your older Fusion 7 scripts will also need to probably have the Lua ipairs code changed as well.

Hi sir
Thank you so much for your reply.


I dont have much knowledge in lua scripting.


I have used LUA ipairs and that is working now.

But what should i use to make "readdir" run in fusion 8.?

Are you trying to adapt one of the bundled Fusion 7 Lua scripts or something you've created on your own?

i create this script.
Here is basic example.

Code: Select all

username =string.lower(os.getenv("USERNAME"))
print(username)


fusion = Fusion("localhost")
composition = fusion:GetCurrentComp()
SetActiveComp(composition)

   drive       =   "d:\\"

   dfolders    =   drive.."*.*"
   ddir      =   readdir(dfolders)
   ddircount    =    table.getn(ddir)

ndirs = {}

   for i = 1,ddircount do
         
         prj = string.upper(ddir[i].Name)   
         table.sort(ndirs)
         table.sort(ndirs)
         
   end
   
data = AskUser("Selector", {
                           {"name",   Name = "USERNAME", "Text",    Default = username,          Lines = 1},
                           {"fill01",  Name = "", "Position", Default = {1, 0.5},   Width = 1.5},
                           {"project", Name = "Select project",    "Dropdown", Options = ndirs, Default = 0},
                           })   
                           
                           
                           if data == nil then
                           return
                           end
                           
                           
                        --  if didnt entered name
                           
                           if data["name"] == "" or data["name"] == " " or data["name"] == "  " or data["name"] == "   " then                           
                           no_name = AskUser("Error", {
                                                   {"info", Name = "No Name", "Text", Lines = 2, Width = 1.5, ReadOnly = true, FontName = "Calibri", FontSize = 18, Default = "You did not entered your name,\nRun Script again and Enter name first"},   
                                                
                                                   })
                                                      
                           
                              if no_name == nil then                              
                              return
                              end
                           return
                           end


trn_name = string.lower(data["trainee"])


Here is a Lua native code snippet example that works with Fusion 7 & 8 and lets you scan a folder for its contents on Windows/Mac/Linux. The directory contents are then filtered by filetype.

You can modify the code to wrap it in your own function to replace your legacy readdir based commands if you want.

Code: Select all

if platform == 'Windows' then

end

print('[Directory Listing]')
-- Search the selected directory for movie content
for files in io.popen(dirCommand):lines() do
  -- List the files
  -- print(files)
 
  -- Add another file to the filesList table
  fileNoCase = files.lower(files)
  if fileNoCase:match('.*%.tif') then
    table.insert(filesList, files)
  end
end

-- List what's in the table
print('[Movie Listing]')
dump(filesList)

print('\n')

Thank you much sir,


this code is working.

My problem is sorted out
