7 The Emacs Interface
The Emacs Interface was originally developed for GNU Emacs 19.34 and is presently being
maintained using XEmacs 21.1 and tested with GNU Emacs 19.34.1. For best performance
and compatibility and to enable all features we recommend that the latest versions of GNU
Emacs or XEmacs are used. For information on obtaining Emacs, see www.emacs.org. For
information specific to GNU Emacs or XEmacs, see www.gnu.org and www.xemacs.org.
7.1 Installation
Starting with SICStus 3.8 the Emacs interface is distributed with SICStus and installed
by
default.
The
default
installation
location for the emacs files is ‘<prefix>/lib/sicstus-3.8/emacs/’ on UNIX platforms
and ‘C:\Program Files\SICStus Prolog\emacs\’ on Windows.
For maximum performance it is recommended, that the Emacs lisp files (extension .el) are
compiled. This can be done from within Emacs with the command M-x byte-compilefile. See section “Installation” in SICStus Prolog Manual, for further details.
7.1.1 Installing On-Line Documentation
It is possible to look up the documentation for any built in or library predicate from within
Emacs (using C-c ? or the menu). For this to work Emacs must be told about the location
of the ‘info’-files that make up the documentation. This can be done for the entire emacs
installation or on a per user basis, see section “Installation” in SICStus Prolog Manual, for
further details.
The default location for the ‘info’-files are ‘<prefix>/lib/sicstus-3.8/doc/info/’ on
UNIX platforms and ‘C:\Program Files\SICStus Prolog\doc\info\’ on Windows.
More recent versions of GNU Emacs and XEmacs should be able to automatically incorporate info files from a subdirectory into the main Info documentation tree. It is therefore
recommended that the SICStus Info files are kept together in their own directory.
