| 26 | Armed Bear Common Lisp (ABCL) is an implementation of ANSI Common Lisp |
|---|
| 27 | that runs in a Java virtual machine. It provides a runtime system, a |
|---|
| 28 | compiler that compiles Lisp source to JVM bytecode, and an interactive |
|---|
| 29 | REPL for program development. |
|---|
| 30 | <br /><br /> |
|---|
| 31 | ABCL is distributed under the terms of the <a href="http://www.gnu.org/copyleft/gpl.html">GNU General Public |
|---|
| 32 | License</a>, with a special linking exception. If you link ABCL with your |
|---|
| 33 | own program, then you do not need to release the source code for that |
|---|
| 34 | program. However, any changes that you make to ABCL itself must be |
|---|
| 35 | released in accordance with the terms of the GPL. The license is the |
|---|
| 36 | same as used by GNU Classpath and J2SE (Java). |
|---|
| 37 | <br /><br /> |
|---|
| 38 | ABCL runs on platforms that support Java 1.5 (or later), including Linux, |
|---|
| 39 | Windows, and Mac OS X. |

|---|
| 41 | ABCL is free software and comes with ABSOLUTELY NO WARRANTY. |

| 43 | The latest version is 0.12.0, released December 14, 2008. |

|---|
| 90 | ABCL is a young implementation (particularly by Lisp standards). |
|---|
| 91 | Even though a lot of energy is spent resolving issues, you may |
|---|
| 92 | well encounter bugs. A number of people have testified to the |
|---|
| 93 | quality of ABCL being good enough for their needs though. See |
|---|
| 94 | the testimonials page. |
|---|
| 95 | <br /><br /> |
|---|
| 96 | ABCL 0.12.0 fails 44 out of 21702 tests in the GCL ANSI test suite |
|---|
| 97 | in interpreted mode. In compiled mode ABCL 0.12.0 fails 48 tests, |
|---|
| 98 | coming from ca 65 in the last release. |
|---|
| 99 | Most notable recent fixes relate to special variables handling |
|---|
| 100 | and making sure the compiler uses the correct environments with, e.g., |
|---|
| 101 | LET/LET* and FLET/LABELS. |
|---|
| 102 | <br /><br /> |
|---|
| 103 | ABCL's CLOS is intolerably slow and does not handle on-the-fly |
|---|
| 104 | redefinition of classes correctly. There is no support for the long |
|---|
| 105 | form of DEFINE-METHOD-COMBINATION, and certain other required CLOS |
|---|
| 106 | features are also missing. Enough CLOS is there to run ASDF and |
|---|
| 107 | CL-PPCRE, if you're in no hurry. There's no MOP worth mentioning. |
|---|
| 108 | <br /><br /> |
|---|
| 109 | Since this is an early public release, there might be build problems as |
|---|
| 110 | well as runtime bugs. |
|---|
| 111 | <br /><br /> |
|---|
| 112 | Please report problems to the <a href="https://lists.sourceforge.net/lists/listinfo/armedbear-j-devel">j development mailing list</a> |
|---|
| 113 | (you must be subscribed to post).<br /><br /> |

|---|
| 115 | <dd>The project is using several ways to test standards compliance as well |
|---|
| 116 | as practical applicability of ABCL by using these projects' test suites |
|---|
| 117 | as 'compliance' indicators: |
|---|
| 118 | <ul> |
|---|
| 119 | <li>ANSI Common Lisp compliance tests</li> |
|---|
| 120 | <li>Maxima - Computer algebra system</li> |

| 130 | The README file in the root directory of the source distribution contains |
|---|
| 131 | instructions for building ABCL. |
|---|
| 132 | <br /><br /> |
|---|
| 133 | Java 1.5 or higher is required; |
|---|
| 134 | <a href="http://java.sun.com/javase/downloads/index_jdk5.jsp">Java 1.5</a> |
|---|
| 135 | is recommended. There are |

|---|
| 138 | performance issues</a> with early versions of Java 1.6. To build ABCL, you'll need |
|---|
| 139 | the full JDK; the JRE is not enough. <br /> |
