What are 'mode' and 'coding'?

What are 'mode' and 'coding'?

[Leo]

Hi there,

One can write "-*-mode:emacs-lisp;coding:utf-8;-*-" on the head of a
file to force emacs to use emacs-lisp-mode and utf-8 coding. I am
wondering what are `mode' and `coding'. I use 'C-h v' on them and
there are no such variables.

Thank you for your help.

It's major-mode and buffer-file-coding-system.

Thanks for your answer.

Are there any other such variables other than 'mode', 'coding' and
'eval'?

Please have a look in the Emacs info system:

C-h i g

Then type this

(Emacs)Specifying File Variables

Yes.

Look for buffer local variables.

See the node "File Variables" in the Emacs manual, it explains all
that.

For the record, there are altogether 4 pseudo variables i.e. mode,
coding, eval and unibyte.

Mode is the Major Mode that the file opens to when it is visited in
Emacs.

Coding is the encoding on the file, ie. UTF-8, Latin1, etc...
