AppDataPath()

[brndx]

Hi,

I'm setting up steam cloud saves and need to know if the method AppDataPath() which returns %USERPROFILE%/AppData/Local/ on Windows will return ~/ on Linux making the settings below correct.

From what it looks like, it seems like your making a new directory under root. I recall LE storing the AppData folder under /home/USER/. The user doesn't have permission to access anything outside their home folder by default. Also, the folder is hidden with a period at the start.

On Linux this command returns the results of a call to getenv("HOME").  I believe this is equivalent to "~/".

[Ma-Shell]

Actually, for linux "~" doesn't have any meaning at all... expanding "~" to the current user's home-directory is a feature of most shells (bash, zsh, ...). This means, if you type "~" in the terminal, the shell that is executing in the terminal replaces this by the user's home-directory. However, if you try to use "~" from your program, it will not mean anything to linux and your program can't do anything with it.

Look at the following example-terminal session:

$ echo foo > ~/bar
$ cat ~/bar
foo
$ python
Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> f = open("~/bar")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: '~/bar'
>>> f = open("/home/user/bar")
>>>

As you can see, e.g. Python can't find the file "~/bar", since "~" doesn't mean anything to it. Using the complete path, however, works.

The same would hold for your Leadwerks LUA/C++ project: You can't use "~" to refer to the current user's home directory. Using the result of getenv("HOME"), as Josh mentioned, is the correct way to get the home-directory. (And yes, for the SHELL it is equivalent to "~/", but for your program)
