Error on http://www.gnu.org/software/emacs/elisp/html_node/Auto-Major-Mode.html

[Decebal]

On this page there is the following code:
          (setq auto-mode-alist
            (append
             ;; File name (within directory) starts with a dot.
             '(("/\\.[^/]*\\'" . fundamental-mode)
               ;; File name has no dot.
               ("[^\\./]*\\'" . fundamental-mode)
               ;; File name ends in `.C'.
               ("\\.C\\'" . c++-mode))
             auto-mode-alist))

But the rule for a file name without a dot should be:
               ("/[^\\./]*\\'" . fundamental-mode)

Where should I tell this so that the error could be modified?


Also on some places end of the filename is written like \\' and on
other places like $. What is the difference between those two?

Do Alt+x report-emacs-bug.

Quote:

«
(add-to-list 'auto-mode-alist '("\\.js\\'" . js2-mode))

Note: The double backslash in the string “\\.js\\'” is used to escape
the backslash. So, the regex engine just got “\.js\'”. The “\.” is to
match a period. The “\'” is one of emacs special regex syntax, to
match end of a string.

See:

• Regexp Backslash - GNU Emacs Lisp Reference Manual

Strictly speaking, using “\” is more proper, but often “$” works too
unless the file name contains newline char. (thanks to Barry who
explained this earlier here)

If I understand it correctly I need to have Emacs configured to send e-
mail, but I found that I can send the bug to bug-gnu-emacs@gnu.org.
I'll do that.

In my case the two would be equivalent (I never have a filename with a
newline in it), but I'll change the occurences with the better one.

me too thought that emacs needs to be config'd in order to send email.
But sometimes last year i realized by accident that whan i do C-c C-c
in mail mode, it nicely switch me to Apple mail app, with a new
compose mail window, with all fields filled like i had in emacs, and
all i have to do is click send.

This is Carbon Emacs for the Mac. I don't know how it is in Windows or
Linux... maybe it is as nice.
