Armed Bear Common Lisp (ABCL)
=============================
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.

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

produce an executable, regardless of the license terms of these
independent modules, and to copy and distribute the resulting

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

CONTAINERIZATION
----------------
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
VM settings:
Max. Heap Size (Estimated): 3.89G
Using VM: OpenJDK 64-Bit Server VM
Armed Bear Common Lisp 1.9.2
Java 17.0.2 Oracle Corporation
OpenJDK 64-Bit Server VM
Low-level initialization completed in 0.432 seconds.
Startup completed in 2.246 seconds.
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.

[Docker Engine]: <https://www.docker.com/products/docker-engine>
RUNNING FROM BINARY RELEASE
---------------------------
After you have downloaded a binary release from either [the
distributed Maven POM graph][maven-abcl] or from
[abcl.org][abcl.org-release] 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.
[maven-abcl]: <https://mvnrepository.com/artifact/org.abcl/abcl/1.9.2>
[maven-abcl-contrib]: <https://mvnrepository.com/artifact/org.abcl/abcl-contrib/1.9.2>
[abcl.org-release]: <http://abcl.org/releases/1.9.2/>
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.
BUILDING FROM SOURCE RELEASE
----------------------------
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][ant].
Unpack the files somewhere convenient, ensuring that the 'ant' (or
'ant.bat' under Windows) executable is in your path and executable.
[ant]: <https://ant.apache.org/bindownload.cgi>
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
[Maven]: <https://maven.apache.org/download.cgi>
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'.
USING APACHE NETBEANS
---------------------
Alternatively, one may install the [Netbeans visual integrated
development environment][netbeans], 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.

SLIME
-----
For usage of ABCL with the [Superior Lisp Interaction Mode for
Emacs][slime], 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)

BUGS
----
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][manual] stating its conformance to the ANSI
standard, providing a compliant and practical Common Lisp
implementation.
[manual]: <https://abcl.org/releases/1.9.2/abcl-1.9.2.pdf>
TESTS
-----
| Version | Failures | Total |
|---------+----------+-------|
| 1.9.2 | 63 | 21902 |
| 1.9.1 | 60 | 21870 |
| 1.9.0 | 61 | 21870 |
| 1.8.0 | 49 | 21848 |
| 1.5.0 | 48 | 21708 |
ABCL 1.9.2 currently fails ~63 out of 21902 the current ANSI test
suite derived from the tests originally written for GCL.
[ansi-test]: <git+https://gitlab.common-lisp.net/ansi-test/ansi-test.git>
Maxima's test suite runs without failures.
ABCL comes with a test suite. Consult the output of `ant help.test`
for more information.
