Indicators of being ran in editor vs ran by bundled version

Questions
#1

What would be the best way to detect if a build was ran through the editor (project->build) ?

#2

Hmm, good question. Not sure if this can be done. Well, maybe. Perhaps look at the current directory? Or maybe something from os.env()?

#3

Any idea on how to best do this? Now that I think about it again, maybe a way to do it would be to check if a file exists within the project directory which would not be specified to be included in the bundled version. That plus checking if it’s on a desktop OS first maybe so on platforms with an editor version it’s not checked.

#4

Checking the existence of a file or checking the current directory should work reasonably well.

#5

Here’s a simple method that seems to work. The context is needing a path to the bundle resources folder so that only one copy of files are needed in project directory.

local M = {}

--- Check if a file or directory exists in this path
function M.exists(file)
	local ok, err, code = os.rename(file, file)
	if not ok then
		if code == 13 then
			-- Permission denied, but it exists
			return true
		end
	end
	return ok, err
end

--- Check if a directory exists in this path
function M.isdir(path)
	-- "/" works on both Unix and Windows
	return M.exists(path.."/")
end

return M

local files = require("main.files")
local sys_info = sys.get_sys_info()

local function is_editor()
  if not (sys_info.system_name == "Windows" or sys_info.system_name == "Darwin" or sys_info.system_name == "Linux") then
    return false
  end

  if files.isdir("bundle_resources") then
    return true
  else
    return false
  end
end
...

  local extra_path = "."

  if is_editor() then
    extra_path = "./bundle_resources/common"
  end

I’m looking to do this as well. Just checking if you are still using this solution?

#7

What about this?

tostring(hash("test")) == "hash: [test]"

Note that this only determines if it’s a debug build or not. Not that it’s running from the editor.

#9

I’m not sure I understand this?

In debug mode, you can print out a hash value and see the original string (i.e. “hash: [test]” in this case).

Whereas in release mode, the debug strings are turned off.

Another option might be to use sys.get_application_path(). When running from the editor, at least on macOS, you’ll get the path to the Defold.app.

local function is_editor()
	local path = sys.get_application_path()
	return path:match(".*%/Defold%.app") ~= nil -- macOS
		or path:match(".*%/Defold%.exe") ~= nil -- Windows
		or path:match(".*%/Defold") ~= nil -- Linux
end
