RE: Changing Color Of Column # In Modeline

[Drew Adams]

    Well, I tried using the first emacs 21 example above and then
    eventually all of them in the last post.  After evaluating it, I would
    toggle "tcl-mode", "which-func-mode", and even "font-lock-mode" in
    various combinations as well as simply exiting emacs and restarting it.
      No luck.  The column value still remains in the same font/weight no
    matter what column I have the cursor on.

    Any ideas what I may be doing incorrectly?

I tested it in GNU Emacs 21.3.1 (i386-mingw-nt5.1.2600) of 2004-03-10 on
NYAUMO. Did you use emacs -q? Do that first (always), to be sure there is
not something else in your environment that is interfering. If it works with
emacs -q but it doesn't work when you load your init file, then email me
off-list and we can try to figure out what the problem is.

I suspect that the problem might be that I showed you `setq', not
`setq-default'. The former only turns this on for the current buffer; the
latter makes it the default behavior. Which one you use depends on how you
want to use this (e.g. in a certain mode hook or systematically). If you
just want this on all the time by default, then use `setq-default'.

1. emacs -q

2. Paste the code (from my email of 11/23 at 10:22) into buffer *scratch*.
That is, the first assignment to mode-line-format (the long one from my
email).

3. M-x eval-buffer

4. C-u M-x column-number-mode

>From then on, whenever the cursor is in column 51 or greater, the column
indicator in the mode line should be bold.

(The hard-coded `50' should ultimately be changed to a user option such as
the `my-column-limit' I provided.)

HTH.
