Lua I/O library

[+me2d09]

I started a new thread, because posts in this topic are little bit OT.

I have made a small Lua-file for testing. It has only one media (txt-file). If you start the cartridge with the emulator, you should see the abc in a MessageBox and in the Lua debug of the emulator. If you start it on the garmin, you will get an "Unexpected error / Closing cartridge".

I have done some research with my Oregon. Firstly: Unexpected error you gets with your test gwc is not thrown on line:

fileHandle = io.open(fileName,"r")

so io.open command is implemented (!) in oregon.

But bad news: this command is unable to open file. Lua function io.open returns a new file handle, or, in case of errors, nil plus an error message.

And on Oregon, it always returns nil and on the second parametr is:

deutsch.txt: No error (errno = 0)

You can test it with command:

fileHandle,err = io.open(fileName,"r")

So there is no error . It looks like a joke from Garmin developers .
