CLISP(1)

NAME
clisp - Common Lisp language interpreter and compiler

SYNOPSIS
clisp [ -h | --help ] [ --version ] [ --license ] [ -B lisplibdir ] [ -M memfile ] [ -m memsize ] [ -L language ] [ -N localedir ] [ -Edomain encoding ] [ -q | --quiet | --silent ] [ -interactive-debug ] [ -w ] [ -I ] [ -ansi ] [ -traditional ] [ -p packagename ] [ -C ] [ -norc ] [ -i initfile ... ] [ -c [ -l ] lispfile [ -o outputfile ] ... ] [ -x expression ] [ lispfile [ argument ] ]

DESCRIPTION
Invokes the common lisp interpreter and compiler. Invoked without arguments, executes a read-eval-print loop, in which expressions are in turn read from standard input, evaluated by the lisp interpreter, and their results output to standard output. Invoked with -c, the specified lisp files are compiled to a bytecode that can be executed more efficiently.

OPTIONS

-h, --help
    Displays a help message on how to use clisp.

--version
    Displays the clisp version number, as given by the function call (lisp-implementation-version).

--license
    Displays a summary of the licensing information, the GNU GPL.

-B lisplibdir
    Specifies the installation directory. This is the directory containing the linking sets and other data files. Directory lisplibdir can be changed at run-time using the symbol-macro *lib-directory*.

-M memfile
    Specifies the initial memory image. This must be a memory dump produced by the saveinitmem function.

-m memsize
    Sets the amount of memory clisp tries to grab on startup. The amount may be given as nnnnnnn (measured in bytes), nnnnK or nnnnKB (measured in kilobytes) or nM or nMB (measured in megabytes). Default is 2 megabytes. The argument is constrained above 100 KB. -- This version of clisp eventually uses the entire memsize.

-L language
    Specifies the language clisp uses to communicate with the user. This may be english. The language may be changed at run-time using the symbol macro *current-language*.

-N localedir
    Specifies the base directory of locale files. clisp will search its message catalogs in localedir/language/LC_MESSAGES/clisp.mo. The localedir may be changed at run-time using the symbol macro *current-language*.

-Edomain encoding
    Specifies the encoding used for a given domain, overriding the default which depends on the environment variables LC_ALL, LC_CTYPE, LANG. domain can be file, affecting *default-file-encoding*, or pathname, affecting *pathname-encoding*, or terminal, affecting *terminal-encoding*, or foreign, affecting *foreign-encoding*, or misc, affecting *misc-encoding*. or blank, affecting all of the above. Note that these values cannot be saved in a memory image. You have to use the init file to set them on startup.

-q, --quiet, --silent
    Quiet: clisp displays no banner at startup and no good-bye message when quitting.

-interactive-debug
    Override the batch mode imposed by -c, -x, and lispfile and allow interactive handling of ASSERT and friends.

-w  Wait for keypress after program termination.

-I  Be ILISP friendly. ILISP is an alternative Emacs interface to Common Lisp systems. With this option, clisp interacts in a way that ILISP can deal with. Currently the only effect of this is that unnecessary prompts are not suppressed.

-ansi
    ANSI CL compliant: comply with the ANSI CL specification even where CLISP has been traditionally different. It sets the symbol macro *ansi* to t. See impnotes.html, section "Maximum ANSI CL compliance", for details.

-traditional
    Traditional: reverses the residual effects of -ansi in the saved image.

-p packagename
    At startup the value of the variable *package* will be set to the package named packagename. The default is the package which was active when the image was saved, normally USER, or COMMON-LISP-USER if the option -a was specified.

-C  Compile when load: At startup the value of the variable *load-compiling* will be set to t. Code being loaded will then be compiled on the fly. This results in slower loading, but faster execution.

-norc
    Normally clisp loads a user run control (RC) file on startup (this happens after the -C option is processed). The file loaded is _clisprc.lisp or _clisprc.fas in the home directory (user-homedir-pathname), whichever is newest. This option, -norc, prevents loading of the RC file.

-i initfile ...
    Specifies initialization files to be loaded at startup. These should be lisp files (source or compiled). Several -i options can be given; all the specified files will be loaded in order.

-c lispfile ...
    Compiles the specified lispfiles to bytecode (*.fas). The compiled files can then be loaded instead of the sources to gain efficiency.

-o outputfile
    Specifies the output file or directory for the compilation of the last specified lispfile.

-l  A bytecode listing (*.lis) of the files being compiled will be produced. Useful only for debugging purposes. See the documentation of compile-file for details.

-x expressions
    Executes a series of arbitrary expressions instead of a read-eval-print loop. The values of the expressions will be output to standard output. Due to the argument processing done by the shell, the expressions must be enclosed in double quotes, and double quotes and backslashes must be preceded by backslashes.

lispfile [argument ...]
    Loads and executes a lispfile. There will be no read-eval-print loop. Before lispfile is loaded, the variable *args* will be bound to a list of strings, representing the arguments. If lispfile is -, the standard input is used instead of a file. If lispfile is an empty string , the rest of the arguments is still available in *args* , for parsing by the init-function of the current image. This option must be the last one. No RC file will be executed.

FILES

main executable

lispinit.mem
    initial memory image

config.lisp
    site-dependent configuration

*.lisp
    lisp source

*.fas
    lisp code, compiled by clisp

*.lib
    lisp source library information, generated and used by the clisp compiler when compiling require forms

*.c C code, compiled from lisp source by clisp for the FFI

ENVIRONMENT

CLISP_LANGUAGE
    specifies the language clisp uses to communicate with the user. The value may be english, german, french, spanish, dutch, russian and defaults to english. The -L option can be used to override this environment variable.

LC_CTYPE
    specifies the locale which determines the character set in use. The value can be of the form language or language_country or language_country.charset, where language is a two-letter ISO 639 language code (lower case), and country is a two-letter ISO 3166 country code (upper case). charset is an optional character set specification, and needs normally not be given because the character set can be inferred from the language and country.

LANG
    specifies the language clisp uses to communicate with the user, unless it is already specified through the environment variable CLISP_LANGUAGE or the -L option. It also specifies the locale determining the character set in use, unless already specified through the environment variable LC_CTYPE. The value may begin with a two-letter ISO 639 language code, for example en, de, fr.

BUGS

When you encounter a bug in clisp , please report it to the mailing list (see http://lists.sf.net/lists/listinfo/clisp-list ) or the SourceForge bug tracker (see http://sf.net/tracker/?func=add&group_id=1355&atid=101355 ).

When submitting a bug report, please specify the following information:

1. What is your platform? ( 'uname -a' on a Unix system) compiler version? libc (on Linux)?

2. Where did you get the sources? When? (Absolute dates are preferred over the relative ones)

3. How did you build clisp ? (What command, options etc.) Please do a clean build (remove your build directory and build with './configure --build build' or at least do a 'make distclean' before 'make' ). If you are reporting a crash (segmentation fault, bus error, core dump etc), please do './configure --with-debug --build build-g' and report the backtrace.

4. If you are using pre-built binaries, the problem is likely to be in the incompatibilities between the platform on which the binary was built and yours; please try compiling the sources.

5. What is the output of 'clisp --version' ?

6. Please supply the full output (copy and paste) of all the error messages, as well as detailed instructions on how to reproduce them.

Known bugs, some of which may be platform-dependent, include

Not all extensions from CLtL2 are supported.

No on-line documentation beyond apropos and describe is available.

PROJECTS
