The option reduce-run-commands must be set correctly
otherwise REDUCE will not run correctly. The settings of other
options are less critical.
REDUCE Run inherits from comint, so comint options also affects this
mode. The comint customization group can be accessed via a
link in the REDUCE Run customization group.
reduce-input-filter ¶Default value "\\`\\([ \t;$]*\\|[ \t]*.[ \t]*\\)\\'". What not
to save on REDUCE Run mode’s input history. The value is a regular
expression (regexp). The default matches any combination of zero or
more whitespace characters and/or statement terminators, or any single
character (e.g. y or n) possibly surrounded by
whitespace.
reduce-packages-directory ¶Absolute pathname of the directory containing REDUCE packages, or nil.
This option should be set automatically when REDUCE Run mode loads.
If the directory cannot be found then this option will be set to nil.
You can customize this variable to override the default setting. The
value may contain spaces and may begin with the shortcut
$reduce, which is replaced with the value of the option
reduce-root-dir-file-name before it is used.
reduce-root-dir-file-name ¶Default value ?:/Program Files/Reduce on Microsoft Windows,
where ? is a letter C–Z, and
/usr/share/reduce on other platforms. Absolute root directory
file name of the REDUCE installation, or nil if not set. It is the
directory containing the packages directory and, on Microsoft
Windows, the bin directory containing the user-executable batch
files. On Microsoft Windows, REDUCE Run mode attempts to determine
the correct drive letter automatically. Note that you can complete
the directory name using M-TAB.
reduce-run-autoload ¶Whether, and if so how, to autoload REDUCE Run mode. Loading it is
necessary only if you plan to run REDUCE within REDUCE IDE. If the
value is t then load REDUCE Run mode after reduce-mode
has loaded; if it is menu (the default) then display a Run
REDUCE menu stub that can load REDUCE Run mode; if it is nil
then do nothing.
reduce-run-autostart ¶Default value t. If non-nil then all commands that require a
REDUCE process will automatically start a new one if none is already
running.
reduce-run-commands ¶The definition of this option changed in version 1.12.
An association list with an element for each version of REDUCE, which
is a list. The first element of each list is the command name as a
string, by default either "CSL" or "PSL"; the second element is either
nil or the value for the environment variable reduce as
a string; the third element is the program to run as a string, which
must be either an absolute pathname or a command name to be looked up
on the execution path; subsequent elements are optional command
arguments as strings. Strings may contain spaces and may begin with
the shortcut $reduce, which is replaced with the value of the
option reduce-root-dir-file-name before it is used. Each
command must run REDUCE using a command-line interface.
By default, REDUCE Run mode on Microsoft Windows uses absolute pathnames and runs REDUCE directly rather than via batch files, whereas on other platforms it uses the shell scripts that should be found on the execution path.
reduce-run-command-name-default ¶Default value the first command name in reduce-run-commands.
If non-nil then the value specifies the default REDUCE command name.
reduce-run-installation-directory ¶Renamed to reduce-root-dir-file-name with a slightly different
definition in version 1.12.
reduce-run-mswin-drives ¶Subsumed into reduce-root-dir-file-name and removed in version
1.12.
reduce-run-multiple ¶Default value t. If non-nil then commands that explicitly
start REDUCE will always start a new REDUCE process in a new distinct
buffer, even if REDUCE is already running. Otherwise, they will
re-use any appropriate running REDUCE process.
reduce-run-prompt ¶Default value "^\\(?:[0-9]+[:*] \\)+". The regexp to recognise
prompts in REDUCE Run mode. This variable is used to initialize
comint-prompt-regexp in the REDUCE run buffer.
reduce-run-terminal ¶Default value nil on Microsoft Windows and "Eterm" on
all other platforms. If non-nil, this specifies the value of
TERM to use, which is intended only for Unix-like platforms.
This sets comint-terminfo-terminal to the value of
reduce-run-terminal and system-uses-terminfo to t
locally within run-reduce so that CSL REDUCE responds
appropriately to interrupts, which with a dumb terminal it does not.
A nil value means use the Emacs defaults. Possible values to
try are "Eterm", "emacs", "xterm".
reduce-source-modes ¶Default value (reduce-mode). Used to determine if a buffer
contains REDUCE source code. If a file is loaded into a buffer that is
in one of these major modes then it is considered to be a REDUCE source
file by reduce-input-file and reduce-fasl-file. Used by
these commands to determine defaults.
