changing bookmark entry

changing bookmark entry

[Mike Ballard]

In ~/.emacs.bnk I have a bookmark which opens an existing file; the file
is continually being written to by another source.  So the line the
bookmark code set to open the file to originally, is now way up near the
top of this growing file whenever I open this bookmark.

How can I change the ~/.emacs.bmk entry to make it always open this
bookmarked file and position point at the end of the buffer instead?

Here's the code as it is now:

(("bookmark title"
  ((filename . "<path to some file>")
   (front-context-string . " 18:32:29 EDT 20")
   (rear-context-string . "t)  - Sat Apr 08")
   (position . 8154)))

Maybe you don't need a bookmark then but just a macro that visits that
file and moves point to the end. Here's an example:

C-x ( C-x C-f d:/mydocu~1/dribdrab <ret> M-> C-x ) <ret> ;; define kbd
macro

M-x name-last-kbd-macro <ret> dribdrab

C-x C-f ;; visit your .emacs

move to where you want the macro definition inserted...

M-x insert-kbd-macro <ret> dribdrab

this produces:

(fset 'dribdrab
   [?\C-x ?\C-f ?d ?: ?/ ?m ?y ?d ?o ?c ?u ?~ ?1 ?/ ?d ?r ?i ?b ?d ?r ?a
?b return ?\M->])

Then you can M-x dribdrab or set dribdrab to a key if you want. I set it
with defalias:

(defalias 'ddb 'dribdrab) for invocation with M-x ddb.

Just change the names to protect the innocent on your system.

(goto-char POSITION) will move point to the end of the buffer if
POSITION is greater than (point-max).  So choose the largest possible
buffer position on your platform:

(defconst most-positive-fixnum (eval '(lsh -1 -1)))

Thanks so much!!  

I couldn't figure out how to use the defconst/var stuff w/o 'integer-p'
kinds of errors so I just did '(position . NNN+)', removed the context
strings and it works perfectly (file size will never get this big anyway
so seems perfectly satisfactory to me; I'm assuming the 'lsh' thing is for
some reason returning an invalid value)...
