My ~/.emacs file now includes the following to fine-tune the default
face for X11 frames:
(when (display-graphic-p)
(set-face-attribute 'default nil :family "DejaVu Sans Mono" :width
'ultra-condensed :height 102)
(require 'color-theme))
The documentation of `set-face-attribute' mentions that :height is
supposed to accept floating point values too:
,----[ C-h f set-face-attribute ]---------------------------------------
| set-face-attribute is a compiled Lisp function in `faces.el'.
|
| (set-face-attribute FACE FRAME &rest ARGS)
|
| Set attributes of FACE on FRAME from ARGS.
| [...]
|
| `:height'
|
| VALUE must be either an integer specifying the height of the font to use
| in 1/10 pt, a floating point number specifying the amount by which to
| scale any underlying face, or a function, which is called with the old
| height (from the underlying face), and should return the new height.
| [...]
`-----------------------------------------------------------------------
But trying to use a floating-point number in my ~/.emacs file throws up
an error, e.g. when I evaluate in my *scratch* buffer the expression:
(set-face-attribute 'default nil :family "DejaVu Sans Mono" :height 1.4)
a debugger pops up with the following backtrace:
Debugger entered--Lisp error: (error "Invalid default face height" 1.4)
internal-set-lisp-face-attribute(default :height 1.4 0)
set-face-attribute(default nil :family "DejaVu Sans Mono" :width
ultra-condensed :height 1.4)
eval((set-face-attribute (quote default) nil :family "DejaVu Sans
Mono" :width (quote ultra-condensed) :height 1.4))
eval-last-sexp-1(nil)
eval-last-sexp(nil)
call-interactively(eval-last-sexp nil nil)
Is the documentation of `set-face-attribute' out of date, or am I using
it incorrectly?
