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. |

78 | ABCL is a young implementation (particularly by Lisp standards). |
---|
79 | Even though a lot of energy is spent resolving issues, you may |
---|
80 | well encounter bugs. A number of people have testified to the |
---|
81 | quality of ABCL being good enough for their needs though. See |
---|
82 | the testimonials page. |
---|
83 | <br /><br /> |
---|
84 | ABCL 0.0.11 fails 47 out of 21702 tests in the GCL ANSI test suite. |
---|
85 | Most notable recent fixes relate to special variables handling |
---|
86 | and making sure the correct environments are used with for example |
---|
87 | LET/LET* and FLET/LABELS. |
---|
88 | <br /><br /> |
---|
89 | ABCL's CLOS is intolerably slow and does not handle on-the-fly |
---|
90 | redefinition of classes correctly. There is no support for the long |
---|
91 | form of DEFINE-METHOD-COMBINATION, and certain other required CLOS |
---|
92 | features are also missing. Enough CLOS is there to run ASDF and |
---|
93 | CL-PPCRE, if you're in no hurry. There's no MOP worth mentioning. |
---|
94 | <br /><br /> |
---|
95 | Since this is an early public release, there might be build problems as |
---|
96 | well as runtime bugs. |
---|
97 | <br /><br /> |
---|
98 | Please report problems to the <a href="https://lists.sourceforge.net/lists/listinfo/armedbear-j-devel">j development mailing list</a> |

---|
101 | <dd>The project is using several ways to test standards compliance as well |
---|
102 | as practical applicability of ABCL by using these projects' test suites |
---|
103 | as 'compliance' indicators: |
---|
104 | <ul> |
---|
105 | <li>ANSI Common Lisp compliance tests</li> |
---|
106 | <li>Maxima - Computer algebra system</li> |

117 | instructions for building ABCL. |

118 | <br /><br /> |

119 | Java 1.5 or higher is required; |

120 | <a href="http://java.sun.com/javase/downloads/index_jdk5.jsp">Java 1.5</a> |

124 | performance issues</a> with early versions of Java 1.6. To build ABCL, you'll need |

125 | the full JDK; the JRE is not enough. <br /> |
