Can't write to files

[00yoshi 0]

When i try to save files with the Filesystem and the Filestream from Filesystem.open i get following error:

 

/lib/filesystem.lua:467: attempt to index local 'self' (a nil value)

stack traceback:

            kernel:730: in function '__index'

            /lib/filesystem.lua:467: in function 'close'

            stdin:1: in main chunk

            [C]: in function 'xpcall'

            kernel: 725: in function 'xpcall'

            /bin/lua.lua:62: in main chunk

           (...tail calls...)

 

I typed this in lua console:

fs = filesystem.open("/mnt/da0/adsfk","w")    --da0 is HDD

fs.write("something")

fs.close() --here it happens

 

Any help is appreciated!

You want to be using `fs:write` and `fs:close` (i.e. with a colon, not a dot).

 

You'll probably also want to use `io.open` instead of `filesystem.open`.

when can i write in a specified line ?

Files don't know "lines", they are a sequence of bytes. You can use file:seek(pos) to move the current position, then the file:read and file:write functions will start reading/writing from that position. (Note that those two functions also move the current position to where they stopped reading/writing.) You'll need to manually find where line breaks ("\n") are though.
