Armed Bear Common Lisp
Armed Bear Common Lisp is a conforming implementation of ANSI X3J13 Common Lisp that runs in a Java virtual machine. It compiles Lisp code directly to Java byte code for execution.
Armed Bear Common Lisp is distributed under the GNU General Public License with a classpath exception (see "Classpath Exception" below).
A copy of GNU General Public License (GPLv2) is included in this distribution, in file:COPYING.
We have modified our GPLv2 license section 13 to read:
13. Linking this library statically or dynamically with other
modules is making a combined work based on this library. Thus, the
terms and conditions of the GNU General Public License cover the
whole combination.
The following paragraph details the "classpath exception" which ABCL
allows as an exception to the statement about linking libraries.
As a special exception, the copyright holders of this software give
you permission to link this software with independent modules to
produce an executable, regardless of the license terms of these
independent modules, and to copy and distribute the resulting
executable under terms of your choice, provided that you also meet,
for each linked independent module, the terms and conditions of the
license of that module. An independent module is a module which is
not derived from or based on this software. If you modify this
software, you may extend this exception to your version of the
software, but you are not obligated to do so. If you do not wish to
do so, delete this exception statement from your version.
We recommend using podman over docker for political reasons, but the
surface syntax is identical so if you must, just substitute docker
for podman
in the following examples.
With podman installed, one may execute:
podman build -t YOURID/abcl .
podman run -it YOURID/abcl
to get something like
illin:~/work/abcl$ podman run -it YOURID/abcl

Type ":help" for a list of available commands.
CL-USER(1):
To install Quicklisp for ABCL in the container run:
podman run -t YOURID/abcl abcl \
--batch --load /home/abcl/work/abcl/ci/install-quicklisp.lisp
See file:Dockerfile for the build instructions.
After you have downloaded a binary release from either the
distributed Maven POM graph or from
abcl.org archive unpack it into its own
directory. To run ABCL directly from this directory, make sure the
Java executable (java
) is in your shell's path. Java 8, 11, 17 are
strongly supported by ABCL, but others may work with a little elbow
grease.
To start ABCL, simply issue the following command:
cmd$ java -jar abcl.jar
which should result in output like the following
Armed Bear Common Lisp 1.9.2
Java 17.0.7 OpenJDK Porters Group
OpenJDK 64-Bit Server VM
Low-level initialization completed in 0.107 seconds.
Startup completed in 0.493 seconds.
CL-USER(1):
Yer now at the interactive ABCL "Read Eval Print Loop" (REPL): hacks 'n glory await.
See the section headed "SLIME" for instructions to connect to this repl from Emacs.
ABCL may be built from its source code by executing the build instructions file:build.xml expressed by the venerable Apache Ant tool. Alternately, one may use the Apache Maven tool as a facade to Ant.
To build, one must have a Java 8, 11, or 17 openjdk installed locally. Just the Java Runtime Environment (JRE) isn't enough, as you need the Java compiler ('javac') to compile the Java source of the ABCL implementation.
Download a binary distribution Ant version 1.7.1 or greater. Unpack the files somewhere convenient, ensuring that the 'ant' (or 'ant.bat' under Windows) executable is in your path and executable.
Then simply executing
cmd$ ant
To use Maven, download it, ensure the mvn
executable is in your
PATH and then
cmd$ mvn -Dmaven.test.skip=true install
from the directory containing the file:build.xml instructions will create an executable wrapper ('abcl' under UNIX, 'abcl.bat' under Windows). Use this wrapper to start ABCL.
The build may be customized by copying file:abcl.properties.in to file:abcl.properties, which will cause Ant to attempt to build incrementally as well as optimizing the runtime for a contemporary 64bit desktop/server machine running Java 8, 11, and/or 17. The file contains incomplete documentation on how it may be edited for subsequent customization. As an alternative to copying the prototype, if one has a version of bash locally, one may issue via Ant
ant abcl.properties.autoconfigure.openjdk.17
or from the shell as
bash ci/create-abcl-properties.bash openjdk17
Currently supported platforms are 'openjdk8', 'openjdk11', 'openjdk13', 'openjdk14', 'openjdk15', 'openjd16', 'openjdk17', 'openjdk18', and 'openjdk19'.
Alternatively, one may install the Netbeans visual integrated development environment, which contains both the Java Development Kit as well as the Ant build tool. The source distribution contains Netbeans-specific project artifacts under file:nbproject for loading ABCL as a Netbeans project.
With Netbeans, one should be able to open the ABCL directory as a
project whereupon the usual build, run, and debug targets as invoked
in the GUI are available. To launch the debugging target it is
currently necessary to have the abcl.build.incremental
Ant property
be set to true
. This can most easily be affected by running the
autoconfigure mechanism for the underlying JVM platform as documented
in the previous section entitlted "BUILDING FROM SOURCE RELEASE".
To connect to the running Netbeans process, one may use the slime
Netbeans configuration connecting to tcp:4:localhost:4005 when
prompted from an invocation M-x slime-connect with Emacs. For this to
work, ASDF must be configured to find a suitably linked SLIME
swank.asd
; the Lisp stanzas in the subsequent section entitled
"SLIME" affect this in the local installation.
For usage of ABCL with the Superior Lisp Interaction Mode for Emacs, one may easily start a Swank listener via:
(require :asdf)
(require :abcl-contrib)
(asdf:load-system :quicklisp-abcl)
(or
(asdf:make :swank)
(ql:quickload :swank))
(swank:create-server :dont-close t)
Armed Bear Common Lisp strives to be a conforming ANSI X3J13 Common Lisp implementation. Any other behavior should be reported as a bug.
ABCL has a User Manual stating its conformance to the ANSI standard, providing a compliant and practical Common Lisp implementation.
| Version | Failures | Total |
|---------+----------+-------|
| 1.9.2 | 63 | 21902 |
| 1.9.1 | 60 | 21870 |

ABCL 1.9.2 currently fails ~63 out of 21902 the current ANSI test suite derived from the tests originally written for GCL.
Maxima's test suite runs without failures.
ABCL comes with a test suite. Consult the output of ant help.test
for more information.
ABCL has many deficiencies, both known and unknown. Descriptions, tests, and even patches to address them will be gladly accepted.
Please report problems to the development mailing list or via opening an issue on either the ABCL trac instance or github.
