Reading files under Löve

I'm struggling to read a file under löve?
I know love.filesystem.open( file ) but that returns a boolean? so how can that boolean be the file? I'm confused by that.
Could someone provide an example of how to open a file and read it line by line? (The tutorials could do with one on reading files if I do say so myself)

I believe it opens a buffer or some shit and the boolean is the success of it.
Once you have opened it you then need to manually read line by line or a given string length. Maybe you have come from an unprofessional shit thing like Garry's Mod where everything is handed to you on a plate with a knife, fork, and dessert. However, here you have almost direct access to the file system.

Psst:
love.filesystem.newFile( filename, mode )
it's not *just* for making new files. you can create a buffer to open your file in with this as well!
that said, booleans are not files. however, booleans can tell you if something is successful or not. newFile returns a file, which can be opened.

I haven't come from Garry's Mod, but I do play Garry's Mod and I've never coded for it, Löve is the only LUA experience I have.
If you really must know my background I started with TGE and I normally code with C++ & OpenGL but I had an idea and felt like making in with Löve.

I was reading the documentation and saw that, thought it would just be for creating files so I didn't have a look
I'll take a gander at it.

Related info:
In the next version, you'll be able to use love.filesystem without having to manage file handles.
Code: Select all
-- Read file contents directly
contents = love.filesystem.read("filename.txt")
-- Iterate over the lines in a file:
for line in love.filesystem.lines("filename.txt") do
...
end
