Invokes the Common Lisp interpreter and compiler.
When called without arguments, executes the read-eval-print loop, in which expressions are in turn
- READ from the standard input,
- EVALuated by the lisp interpreter,
- and their results are PRINTed to the standard output.
Non-Interactive (Batch) Mode
Invoked with -c, compiles the specified lisp files to a platform-independent bytecode which can be executed more efficiently.
Invoked with -x, executes the specified lisp expressions.
Invoked with lisp-file, runs the specified lisp file.
Displays a help message on how to invoke CLISP.
Displays the CLISP version number, as given by the function LISP-IMPLEMENTATION-VERSION, the value of the variable *FEATURES*, as well some other information.
Displays a summary of the licensing information, the GNUGPL.
Displays information about the memory image being invoked: whether is it suitable for scripting as well as the :DOCUMENTATION supplied to EXT:SAVEINITMEM.
- -B lisp-lib-dir
Specifies the installation directory. This is the directory containing the linking sets and other data files. This option is normally not necessary, because the installation directory is already built-in into the clisp executable. Directory lisp-lib-dir can be changed dynamically using the SYMBOL-MACROCUSTOM:*LIB-DIRECTORY*.
Print the installation directory and exit immediately. The namestring of CUSTOM:*LIB-DIRECTORY* is printed without any quotes. This is mostly useful in module Makefiles, see, e.g., modules/syscalls/Makefile.in (file in the CLISP sources).
- -K linking-set
Specifies the linking set to be run. This is a directory (relative to the lisp-lib-dir) containing at least a main executable (runtime) and an initial memory image. Possible values are
the core CLISP
core plus all the modules with which this installation was built, see Section 32.2, “External Modules”.
The default is base.
- -M mem-file
Specifies the initial memory image. This must be a memory dump produced by the EXT:SAVEINITMEM function by this clisp runtime. It may have been compressed using GNUgzip.
- -m memory-size
Sets the amount of memory CLISP tries to grab on startup. The amount may be given as
measured in bytes
measured in machine words (4×n on 32-bit platforms, 8×n on 64-bit platforms)
measured in kilobytes
measured in kilowords
measured in megabytes
measured in megawords
The default is 3 megabytes. The argument is constrained above 100 KB.
This version of CLISP is not likely to actually use the entire memory-size since garbage-collection will periodically reduce the amount of used memory. It is therefore common to specify 10 MB even if only 2 MB are going to be used.
- -L language
Specifies the language CLISP uses to communicate with the user. This may be one of english, german, french, spanish, dutch, russian, danish. Other languages may be specified through the environment variableLANG, provided the corresponding message catalog is installed. The language may be changed dynamically using the SYMBOL-MACROCUSTOM:*CURRENT-LANGUAGE*.
- -N locale-dir
Specifies the base directory of locale files. CLISP will search its message catalogs in locale-dir/language/LC_MESSAGES/clisp.mo. This directory may be changed dynamically using the SYMBOL-MACROCUSTOM:*CURRENT-LANGUAGE*.
- -Edomain encoding
Specifies the encoding used for the given domain, overriding the default which depends on the environment variables LC_ALL, LC_CTYPE, LANG. domain can be
affecting all of the above.
Note that the values of these SYMBOL-MACROs that have been saved in a memory image are ignored: these SYMBOL-MACROs are reset based on the OS environment after the memory image is loaded. You have to use the RC file, CUSTOM:*INIT-HOOKS* or init function to set them on startup, but it is best to set the aforementioned environment variables appropriately for consistency with other programs. See Section 31.1, “Customizing CLISP Process Initialization and Termination”.
Change verbosity level: by default, CLISP displays a banner at startup and a good-bye message when quitting, and initializes *LOAD-VERBOSE* and *COMPILE-VERBOSE* to T, and *LOAD-PRINT* and *COMPILE-PRINT* to NIL, as per [ANSI CL standard]. The first -q removes the banner and the good-bye message, the second sets variables *LOAD-VERBOSE*, *COMPILE-VERBOSE* and CUSTOM:*SAVEINITMEM-VERBOSE* to NIL. The first -v sets variables CUSTOM:*REPORT-ERROR-PRINT-BACKTRACE*, *LOAD-PRINT* and *COMPILE-PRINT* to T, the second sets CUSTOM:*LOAD-ECHO* to T. These settings affect the output produced by -i and -c options. Note that these settings persist into the read-eval-print loop. Repeated -q and -v cancel each other, e.g., -q -q -v -v -v is equivalent to -v.
- -on-error action
Establish global error handlers, depending on action:.PP appease
continuableERRORs are turned into WARNINGs (with EXT:APPEASE-CERRORS) other ERRORs are handled in the default way
ERRORs INVOKE-DEBUGGER (the normal read-eval-print loop behavior), disables batch mode imposed by -c, -x, and lisp-file,
continuableERRORs are appeased, other ERRORs are ABORTed with EXT:ABORT-ON-ERROR
continuableERRORs are appeased, other ERRORs terminate CLISP with EXT:EXIT-ON-ERROR (the normal batch mode behavior).
See also EXT:SET-GLOBAL-HANDLER.
Start an interactive read-eval-print loop after processing the -c, -x, and lisp-file options and on any ERRORSIGNALed during that processing.
Disables batch mode.
Wait for a keypress after program termination.
Interact better with Emacs (useful when running CLISP under Emacs using SLIME, ILISP et al). With this option, CLISP interacts in a way that Emacs can deal with:
- unnecessary prompts are not suppressed.
- The GNUreadline library treats TAB (see TAB key) as a normal self-inserting character (see Q: A.4.6).
Do not use GNUreadline even when it has been linked against. This can be used if one wants to paste non-ASCII characters, or when GNUreadline misbehaves due to installation (different versions on the build and install machines) or setup (bad TERM environment variable value) issues.
Comply with the [ANSI CL standard] specification even where CLISP has been traditionally different by setting the SYMBOL-MACROCUSTOM:*ANSI* to T.
Traditional: reverses the residual effects of -ansi in the saved memory image.
Provides a modern view of symbols: at startup the *PACKAGE* variable will be set to the “CS-COMMON-LISP-USER” package, and the *PRINT-CASE* will be set to :DOWNCASE. This has the effect that symbol lookup is case-sensitive (except for keywords and old-style packages) and that keywords and uninterned symbols are printed with lower-case preferrence. See Section 11.5, “Package Case-Sensitivity”.
- -p package
At startup the value of the variable *PACKAGE* will be set to the package named package. The default is the value of *PACKAGE* when the image was saved, normally “COMMON-LISP-USER”.
Compile when loading: at startup the value of the variable CUSTOM:*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.
Normally CLISP loads the 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 newer. This option, -norc, prevents loading of the RC file.
- -lp directory
Specifies directories to be added to CUSTOM:*LOAD-PATHS* at startup. This is done after loading the RC file (so that it does not override the command-line option) but before loading the init-files specified by the -i options (so that the init-files will be searched for in the specified directories). Several -lp options can be given; all the specified directories will be added.
- -i init-file
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 lisp-file
Compiles the specified lisp-files to bytecode (*.fas). The compiled files can then be LOADed instead of the sources to gain efficiency.
Imposes batch mode.
- -o outputfile
Specifies the output file or directory for the compilation of the last specified lisp-file.
Produce a bytecode DISASSEMBLE listing (*.lis) of the files being compiled. Useful only for debugging. See Section 24.1, “Function 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 escaped with backslashes.
Imposes batch mode.
- lisp-file [ argument ... ]
Loads and executes a lisp-file, as described in Section 32.6.2, “Scripting with CLISP”. There will be no read-eval-print loop. Before lisp-file is loaded, the variable EXT:*ARGS* will be bound to a list of strings, representing the arguments. The first line of lisp-file may start with #!, thus permitting CLISP to be used as a script interpreter. If lisp-file is -, the *STANDARD-INPUT* is used instead of a file.
This option is disabled if the memory image was created by EXT:SAVEINITMEM with NIL:SCRIPT argument. In that case the LISTEXT:*ARGS* starts with lisp-file.
This option must be the last one.
No RC file will be executed.
Imposes batch mode.
As usual, -- stops option processing and places all remaining command line arguments into EXT:*ARGS*.
The language implemented is ANSICommon Lisp. The implementation mostly conforms to the ANSI Common Lisp standard, see Section 31.10, “Maximum ANSI CL compliance”. [ANSI CL] ANSI CL standard1994. ANSI INCITS 226-1994 (R1999)

Command Line User Environment
get context-sensitive on-line help, see Chapter 25, Environment.
- (APROPOS name)
list the SYMBOLs matching name.
- (DESCRIBE symbol)
describe the symbol.
- EOF (Control+D on UNIX)
leave the current level of the read-eval-print loop (see also Section 1.1, “Special Symbols ”).
- arrow keys
for editing and viewing the input history, using the GNUreadline library.
- TAB key
- If you are in the “function position” (in the first symbol after an opening paren or in the first symbol after a #´), the completion is limited to the symbols that name functions.
- If you are in the "filename position" (inside a string after #P), the completion is done across file names, GNUbash-style.
- If you have not typed anything yet, you will get a help message, as if by the help command.
- If you have not started typing the next symbol (i.e., you are at a whitespace), the current function or macro is DESCRIBEd.
- Otherwise, the symbol you are currently typing is completed.
Using and Extending Clisp
Common Lisp is a programmable programming language. —John Foderaro.PP When CLISP is invoked, the runtime loads the initial memory image and outputs the prompt; at which one can start typing DEFVARs, DEFUNs and DEFMACROs.
To avoid having to re-enter the same definitions by hand in every session, one can create a lisp file with all the variables, functions, macros, etc.; (optionally) compile it with COMPILE-FILE; and LOAD it either by hand or from the RC file; or save a memory image to avoid the LOAD overhead.
However, sometimes one needs to use some functionality implemented in another language, e.g., call a C library function. For that one uses the Foreign Function Interface and/or the External Modules facility. Finally, the truly adventurous ones might delve into Extending the Core.

When you encounter a bug in CLISP or in its documentation (this manual page or CLISP impnotes), please report it to the CLISPSourceForge bug tracker.
Before submitting a bug report, please take the following basic steps to make the report more useful:
1. Please do a clean build (remove your build directory and build CLISP with ./configure --cbc build or at least do a make distclean before make).
2. If you are reporting a “hard crash” (segmentation fault, bus error, core dump etc), please do ./configure --with-debug --cbc build-g ; cd build-g; gdb lisp.run, then load the appropriate linking set by either base or full gdb command, and report the backtrace (see also Q: A.1.1.10).
3. If you are using pre-built binaries and experience a hard crash, 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 and report the problem if it persists.
When submitting a bug report, please specify the following information:
1. What is your platform (uname -a on a UNIX system)? Compiler version? GNUlibc version (on GNU/Linux)?
2. Where did you get the sources or binaries? When? (Absolute dates, e.g., “2006-01-17”, are preferred over the relative ones, e.g., “2 days ago”).
3. How did you build CLISP? (What command, options &c.)
4. What is the output of clisp --version?
5. Please supply the full output (copy and paste) of all the error messages, as well as detailed instructions on how to reproduce them.
