Large fonts for Sore Eyes
The size of the standard fonts on the Lispm is inadequate for some of our
people. The following is code we use to adjust the various fonts for them.
(Perhaps something else could be done, like redefining what font
FIX.ROMAN.NORMAL maps to???)
I'm throwing it out for other people to use and/or improve. Paul: if you'd
like to put this into the library, please feel free. Symbolics: If you'd
like to advise us of a better way to do this or to clean things up so that
it works better or more easily, please do!
P.S. You can probably also use something like this to make your demos
more readable to people further from the machine. (BUT try it out first
as changing font sizes causes all sorts of problems with layouts, menus,
and such.)
The user's login file has something like:
(load "library:sri;large-font")
(login-forms
(cl-user::install-large-character-styles)
(cl-user::install-large-printer-fonts))
Here is the file LIBRARY;SRI;LARGE-FONT:
;;; -*- Mode: LISP; Syntax: Common-Lisp; Package: USER; Base: 10; Default-character-style: (:FIX :ROMAN :NORMAL) -*-
;;;1 This is for making a Lispm have large font for most windows.
0;;;1 (Some people have trouble seeing the standard size font.)
0;;;1 Please always call this within a LOGIN-FORMS, ie
0;;;1 (LOGIN-FORMS
0;;; 1(INSTALL-LARGE-CHARACTER-STYLES)
0;;; 1(INSTALL-LARGE-PRINTER-FONTS))
0;;;1 NOTE: SRI has some non-standard size printers and you WILL need to
0;;;1 do something different for your printers in INSTALL-LARGE-PRINTER-FONTS
0;;;1 This code handles Lisp listeners, All Dynamic Windows(?), Editors,
0;;;1 and Telnet windows.
0;;;1 The most obvious problem not handled is that the mode-line of an editor
0;;;1 can't change in size once the window was originally set up (possibly
0;;;1 with a smaller font). Thus the typeout to that window may not quite fit.
0;;; Don't forget you can create a new Editor after installing the large styles.
