NAME
cadabra - field-theory motivated computer algebra system
SYNOPSIS
cadabra
DESCRIPTION
Cadabra is a computer algebra system for the manipulation of tensorial
expressions.
The output of cadabra is either plain text or UTF8 encoded Unicode (see
the environment variables described below). The line-breaking
properties of the latter are used to wrap large expressions are
reasonable points. In addition to the standard output, cadabra can
print status information, which is wrapped in special
<status>...</status> blocks.
OPTIONS
--silent
Disables all output, except for output generated by the @print
algorithm.
--loginput
Copy the input into the log file.
--input filename
Read the indicated file as input before switching to console
input.
--prompt string
Set the prompt of the interactive session to the indicated
string.
ENVIRONMENT VARIABLES
The following variables toggle various features on or off, depending on
whether the variable is set or not:
CDB_PRINTSTAR
Display a star to indicate products. Without this setting, a
space is used.
CDB_USE_UTF8
Use UTF8 encoding for output. This in particular will introduce
non-breakable spaces to group objects together, as well as zero-
width non-breakable spaces to prevent line-breaks after
brackets, underscore and caret symbols. When this variable is
not set, the output will be plain ASCII without any special
symbols.
