Strange problem with (setq buffer-read-only t).

Strange problem with (setq buffer-read-only t).

[Andy Stewart]

Hi all,

I have develop irfc.el (interface for IETF RFC document) at:
http://www.emacswiki.org/emacs-en/irfc.el

I use (setq buffer-read-only t) in function `irfc-mode' for make RFC
buffer read-only.

And strange thing is, the (setq buffer-read-only t) that write in code looks
no effect.
But everything is okay if i eval (setq buffer-read-only t) after i open
RFC document.

Why not effect in my code?

So strange....

Andy idea?

Thanks.

What do you mean with "no effect"?

I just tried irfc.el and RFC buffers are indeed read-only.

Which version of Emacs are you using? What steps should I follow to
reproduce the bug?

I use 23.0.60.1, i find if i association rfc[0-9]+\\.txt with
'irfc-mode', then buffer is not read-only when it open, even i write
(setq buffer-read-only t) in source code.

But RFC buffer can read-only if i eval-expression "(setq buffer-read-only t)" with
*after* i open RFC buffer.

Please do a precise recipe, starting from emacs -Q.

For example, I move to the directory containing the RFCs and I do:

  emacs -Q -l irfc.el rfc2866.txt

and RFC2866 opens in read-only mode.

Yep, buffer is read-only inneed.
Strange, i think have something wrong with this....

Thank you very much!
