    os.execute(...)

    edited April 2021 in General questions
    hope you are all doing fine :o
    Is it possible to execute a cmd line to a program included in my gideros assets project?
    For example I would like to run the fbx-conv.exe from code.
    I included fbx-conv.exe at the root of the assets folder:

    then I call:
    	local initpath = self.modelpath or "c:/"
	local path = application:get("openFileDialog", "Choose|"..initpath.."|Fbx (*.fbx)") -- title|path|extensions
	if path ~= 0 then
		self:getFolderPathAndFileName(path)
		local fbx = self.finalfile
		local json = fbx:gsub(".fbx", ".json")
		os.execute("start fbx-conv.exe -f -v -o G3DJ ".."\""..self.finalfolder.."/"..fbx.."\"".." ".."\""..self.finalfolder.."/"..json.."\"")
	end
    The problem is windows cannot find fbx-conv.exe.

    When I run the code (print) directly from cmd this works fine.

    My question is how to access fbx-conv.exe from my code?
    I tried |R|fbx-conv.exe, assets\resource\fbx-conv.exe, ...

    Thank you for your help :)

      I kinda solved it :o
      First I need to ask the user the path to fbx-conv.exe
      then I use the path in os.execute:
      	local initpath0 = "c:/" local fbxconvpath = nil
	local path0 = application:get("openFileDialog", "Choose|"..initpath0.."|Fbx Conv (*.exe)") -- title|path|extensions
	if path0 ~= 0 then
		print(path0)
		fbxconvpath = path0
	end
 
	local initpath = self.modelpath or "c:/"
	local path = application:get("openFileDialog", "Choose|"..initpath.."|Fbx (*.fbx)") -- title|path|extensions
	if path ~= 0 then
		self:getFolderPathAndFileName(path)
		local fbx = self.finalfile
		local json = fbx:gsub(".fbx", ".json")
		os.execute("start "..fbxconvpath.." -f -v -o G3DJ ".."\""..self.finalfolder.."/"..fbx.."\"".." ".."\""..self.finalfolder.."/"..json.."\"")
	end
      Now I need to store this path and reuse it :)

      Viva gideros!

      Assuming current work directory when your app is launched is the app root folder, I would have tried to run 'assets/fbx-conv.exe'. The thing is that os.execute() isn't aware of Gideros virtual folders such as |R|, |D| or |T|.

      I think I tried that before, but I tried it again but file not found

      My solution (see previous post) is not too bad imho, I keep it this way until I do some more testing. Thanks for your answer :)

      If you REALLY want to run a program from project directory, you can use
      --go to addons example, and use "studio.lua" from there
Studio.listFiles()
      Something like this:
      function executeFile(appName, params)
	params = params or ""
	if (application:isPlayerMode()) then 
		local status, error = false, ""
		if (not Studio) then 
			status, error = pcall(require, "studio")
		else
			status = true
		end
 
		if (status) then 
			local files = Studio.listFiles()
			local path = ""
			for i,v in ipairs(files) do 
				if (v.name == appName) then 
					path = v.source
					break
				end
			end
			assert(path ~= "", "Cant find \""..appName.."\"")
			os.execute(("start %s %s"):format(path, params))
		else
			print(error)
		end
	else
		local path = application:get("directory","executable")
		path = path .. "/assets/resource/"..appName
		os.execute(("start %s %s"):format(path, params))
	end
end
-- usage:
executeFile("MyExe.exe", "-f -v")
      Works for player mode and exported windows application (but if assets is NOT encoded).
      And remember to use addon player to make it work :D

      Thank you rrraptor for your answer :) It is a bit complicated for my taste, I will use my answer in previous post for now.
