How to change `standard-display-table' at startup.

How to change `standard-display-table' at startup.

[David Hansen]

Hello,

I have

(aset standard-display-table ?\`
      (make-vector 1 (make-glyph-code ?\` 'bold)))

in my .emacs but Emacs complains that `standard-display-table' is nil
and not a vector.  How can I change the `standard-display-table' at
startup?

Does it help to do this in after-init-hook?

Sounds like a bug - or perhaps something in your .emacs set it to nil?

emacs -Q
C-h v standard-display-table

standard-display-table is a variable defined in `C source code'.
Its value is 
#^[t nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil
nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil
nil nil nil nil nil nil nil nil nil ni...

Oops. What Eli said makes more sense.

Still ``Wrong type argument: arrayp, nil''.

I'm sorry, maybe I should say:

GNU Emacs 23.0.60.3 (i686-pc-linux-gnu, GTK+ Version 2.12.9) of
2008-06-06 on robotron

Could anyone try this on 22.0?  Might be this is on the wrong list...

(unless standard-display-table
  (setq standard-display-table (make-display-table)))

If you start Emacs as "emacs -Q", and type "C-h v
standard-display-table RET" after Emacs starts up, do you see a nil
value then as well?

If the value is nil, please report a bug (I cannot reproduce it here,
btw).  If the value is not nil, explore the other -hook variables
supported by startup.el: emacs-startup-hook, term-setup-hook, and
window-setup-hook.

There's nothing abnormal about standard-display-table being nil.

Depending on the configuration and platform, it could be highly
unusual if not abnormal, and this list isn't a good place to discuss
that anyway.

X-Post & fup2 to emacs-devel

When I run emacs -Q, i get:

standard-display-table is a variable defined in `C source code'.
Its value is nil

this is 

GNU Emacs 23.0.60.3 (i686-pc-linux-gnu, GTK+ Version 2.12.9) of
2008-06-06 on robotron

Strange...  Anyway, does it work to do what Johan suggested:

    (unless standard-display-table
      (setq standard-display-table (make-display-table)))

Yes, that works.  Another oddity I just encountered:  C-u C-x = on a
backtick signals an error:

Debugger entered--Lisp error: (wrong-type-argument characterp 4194400)
  get-char-code-property(4194400 iso-10646-comment)
  describe-char(193)
  what-cursor-position((4))
  call-interactively(what-cursor-position nil nil)

Not here, not on the ASCII backtick, anyway.  Are you sure you typed
the backtick character, ASCII code 96, and not some similar Unicode
character?  The large character code suggests it's not an ASCII
backtick.

Nah, the backtick is the char I changed in the display table to get it
displayed with the bold face.

You should have taken this to emacs-devel long ago.

I had, but you replied here again.  Maybe X-Post via gmane to both
groups and reading via mail on the other end is to confusing...
