JAS: Java Algebra System
========================
Version 2.7, 2023
by Heinz Kredel, University of Mannheim, kredel at rz.uni-mannheim.de
Copyright (c) 2000-2023 by Heinz Kredel.
Programms released under GPL or LGPL, see COPYING.jas or COPYING.lgpl.jas.
Web home-page: http://krum.rz.uni-mannheim.de/jas/
Requirements
------------
A Java JDK 1.11.
Documentation see index.html.
Required libraries are log4j-core-2.17.1.jar, log4j-api-2.17.1.jar
(from Apache Log4j2 or jars from some other compatible logging
framework like SLF4J)
and junit-4.12.jar, hamcrest-core-1.3.jar (from Junit 4 for tests in trc)
Usage
-----
> java -cp {other_jar_files}:jas-<version>-bin.jar:. <sample class>
for example
> java -cp ../lib/log4j-core-2.17.1.jar:../lib/log4j-api-2.17.1.jar:jas-2.6.5428-bin.jar edu.jas.application.RunGB seq examples/trinks7.jas
or
> jruby examples/<some input file>.rb
or
> jas examples/<some input file>.rb
for example
> ./jas examples/all_rings.rb
or
> jython examples/<some input file>.py
or
> jas -py examples/<some input file>.py
The shell script "jas" figures out the Java, jruby, jython and JAS
environment and runs the respective scripting interpreter. See
> man -l doc/jas.1
for more information.
Compilation of your own Java files using the JAS library can be done
with the "javac" command.
> javac -cp {other_jar_files}:jas-<version>-bin.jar:. <your sample code>
Versions and jar files
----------------------
JAS is distributed in 3 jar files:
jas-<version>-bin.jar: or
jas-<version>.jar: the Java class files
jas-<version>-src.zip: the java source code
jas-<version>-doc.zip: the Java doc, epydoc, jrdoc and more info files
optional jar files which require further installed packages:
jas-meditor.jar: the interface to meditor
jas-jython.jar: an interface for Java scripting
jas-mpj.jar: MPI Java depending code
mylog.jar: a substitute for log4j to use Java logging
nolog.jar: a substitute for log4j to disable any logging
droidlog.jar: a substitute for log4j to use Android logging
jlinalg_adapter.jar: an adaptor to parts of JLinAlg
commons-math_adapter.jar: an adaptor to parts of Apache commons.math
pre packaged JAS versions:
jas-java_<version>-all.deb a Debian 10 (buster) package usable in MathLibre
ruboto-irb-jas-release.apk an Android App based on Ruboto (defunct)
There are GIT repositories for the scource code, which can be cloned with
> git clone http://krum.rz.uni-mannheim.de/jas.git jas
or
> git clone https://github.com/kredel/java-algebra-system.git jas
There is a Maven compatible repository for bytecode, source and javadocs at
https://oss.sonatype.org/
groupId: de.uni-mannheim.rz.krum, artifactId: jas, version (for example): 2.7.50
The version is specified by a two digit major.minor number and a
revision number. The revision number was the subversion revision
number, but with git it is just a consecutive number. For example in
jas-2.7.80-bin.jar
"2.7" is the JAS version number and
"80" is the git revision number
The jas-*-bin.jar and jas-*-doc.jar can be generated from jas-*-src.jar.
The fastest way to get a complete JAS install, is
> jar -xf jas-<version>-src.zip
> cd <JAS version number>
> jar -xf jas-<version>-bin.jar
> jar -xf jas-<version>-doc.zip
If you have a working Ant with Ivy, the last two steps can be replaced by
> ant resolve
> ant compile
> ant doc
provided you have setup build.xml, ivy.xml for the required libraries.
