Abstract

See the section called “Bugs” for instructions on how to report bugs (both in these notes and in CLISP itself).
See Q: A.1.1.5 for information on CLISP support.

These notes discuss the CLISP implementation of Common Lisp by and . The current maintainers are and .
This implementation is mostly conforming to the [ANSI CL standard] available on-line as the [Common Lisp HyperSpec] (but the printed ANSI document remains the authoritative source of information). [ANSI CL standard] supersedes the earlier specifications [CLtL1] and [CLtL2].
The first part of these notes, Part I, “Chapters or the Common Lisp HyperSpec”, is indexed in parallel to the [Common Lisp HyperSpec] and documents how CLISP implements the [ANSI CL standard].
The second part, Part II, “Common Portable Extensions”, documents the
common extensions to the [ANSI CL standard], specifically Meta-Object Protocol and “GRAY”
STREAMs.
The third part, Part III, “Extensions Specific to CLISP”, documents the CLISP-specific extensions, e.g., Section 32.4, “Socket Streams”.
The fourth part, Part IV, “Internals of the CLISP Implementation”, is intended mostly
for developers as it documents the CLISP internals, e.g., garbage-collection,
adding new built-ins, and the bytecodes generated by the compiler
(i.e., what is printed by DISASSEMBLE).
The following is the mark-up notations used in this document:

| Class, type | REGEXP:MATCH |
| Format instruction | ~A |

| Data (CLISP is likely to print it) | #(1 2 3) |
| Program listing |

| Bytecode instruction | (STOREV |
| First mention of an entity | firstterm |
| External module | libsvm, bindings/glibc |
| Command line argument | -x |
