io.open() question

[Silver Ankh]

I have two directories: [LOVE2D directory] and [App directory]. When I start app from LOVE2D directory using love.exe "App directory", for every newImage, newSource, newFont etc. current directory is [App directory], only for io.open current directory is [LOVE2D directory]. Is this OK? Seems to be little bit inconsistent.

The io. module doesn't work in Love2D as far as I know.
We use "love.filesystem" instead.
I don't think you should need access outside of the game folder.
For saving stuff, you are supposed to use the /%User/AppData/ folder.

Is working for me. I used io.open and file:lines.
Now I found love.filesystem.lines
I'll change this in my app for better consistency.
Thank you!

the io module does work, but it has a few shortcomings, mainly that it's OS-dependent how it works, and that you can't use that with löve's constructor functions (love.*.new*) since those use löve's own filesystem library. (Also, not specifically io-module related, but nowadays, OS-es think they have the right to dictate where programs can read/write, so that can also be a problem.)

Also, where the CWD or current working directory is is dependent on tons of things; even how a batch file is coded can mess with it:

Code: Select all

-- If your bat file is in the directory where love.exe is, then:
love "path/to/project/folder"
-- If it's in your project directory, where main.lua is, then:
"path/to/love.exe" .\
-- If it's anywhere else, then:
"path\to\love.exe" "path/to/project/folder"

All three of those might have the CWD at different locations, which is why you shouldn't rely on that.
You should use love.filesystem's directory querying functions instead.

Thanks for the explanation!
