## Name

`clisp` - Common Lisp language interpreter and compiler

## Synopsis

`clisp` [ `-h` ] [ `-m` memsize ] #ifndef NO_SP_MALLOC [ `-s` stacksize ] #endif #ifdef MULTIMAP_MEMORY_VIA_FILE [ `-t` tempdir ] #endif [ `-M` memfile ] [ `-L` language ] [ `-q` ] [ `-I` ] [ `-i` initfile ... ] [ `-c` [ `-l` ] lispfile [ `-o` outputfile ] ... ] [ `-x` expression ]

## 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`
  Displays a help message on how to use `clisp`.

`-m` memsize
  Sets the amount of memory `clisp` tries to grab on startup. The amount may be given as nnnnnnn (measured in bytes), nnnn `K` or nnnn `KB` (measured in kilobytes) or n `M` or n `MB` (measured in megabytes). #ifdef WIDE Default is 4 megabytes. #else Default is 2 megabytes. #endif #if (oint_addr_len+addr_shift==24) The argument is constrained between 100 KB and 16 MB. #elif (oint_addr_len+addr_shift==26) The argument is constrained between 100 KB and 64 MB. #elif (oint_addr_len+addr_shift==28) The argument is constrained between 100 KB and 256 MB. #else The argument is constrained above 100 KB. #endif #ifndef SPVW_MIXED_BLOCKS -- This version of `clisp` allocates memory dynamically. memsize is essentially ignored.

  #endif #ifndef NO_SP_MALLOC

`-s` stacksize
  Sets the size of the stack `clisp` allocates for itself. The syntax is the same as for memsize. Default is one eighth of memsize. The argument is constrained between 40 KB and 8 MB.

  #endif #ifdef MULTIMAP_MEMORY_VIA_FILE

`-t` tempdir
  Specifies the directory where the temporary core file is to be held. This option takes precedence over the environment variable `TMPDIR`.

  #endif

`-M` memfile
  Specifies the initial memory image. This must be a memory dump produced by the saveinitmem function. #ifdef UNIX It may have been compressed using GNU gzip. This option is normally already set by the shell script `/usr/local/bin/clisp`.

  #endif

`-L` language
  Specifies the language `clisp` uses to communicate with the user. This may be `english`, `deutsch`, `francais`.

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

`-I`
  ILISP friendly: `clisp` interacts in a way that ILISP (a popular Emacs LISP interface) can deal with. Currently the only effect of this is that unnecessary prompts are not suppressed.

`-i` initfile ...
  Specifies initialization files to be `load`ed at startup. These should be lisp files (source or compiled).

`-c` lispfile ...
  Compiles the specified lispfiles to bytecode. The compiled files can then be `load`ed 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 of the files being compiled will be produced. Useful only for debugging purposes.

`-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 single quotes, and double quotes and backslashes must be preceded by backslashes.

  #ifdef EMUNIX

`@`optionfile
  substitutes the contents of optionfile as arguments. Each line of optionfile is treated as a separate argument to `clisp`.

  #endif

#ifdef AMIGAOS

## Workbench

Two kinds of tooltypes are supported:

`WINDOW=`windowspec
  `clisp` will communicate with the console window or pipe specified by windowspec.

`ARGS=`arguments
  Specifies the command line arguments for `clisp`. Within arguments the token `*` may be used to denote the project's filename. arguments defaults to `-i *` which means that the file will be `load`ed (see above).

#endif

## Use

`help`
  to get some on-line help.

`(apropos` name`)`
  lists the symbols relating to name.

`(exit)` or `(quit)` or `(bye)`
  to quit `clisp`.

  #if defined(UNIX) || defined(MSDOS) || defined(AMIGAOS)

#ifdef UNIX EOF (Ctrl-D) #endif #ifdef MSDOS EOF (Ctrl-Z) #endif #ifdef AMIGAOS EOF (Ctrl-\e) #endif
  to leave the current read-eval-print loop.

  #endif #ifdef GNU_READLINE

arrow keys
  for editing and viewing the input history.

Tab key
  to complete the symbol's name you are just typing.

## Files

#ifdef UNIX
`clisp`
  startup script

  #endif

#if defined(UNIX) `lisp.run` #endif #if defined(MSDOS) `lisp.exe` #endif #if defined(ATARI) `lisp.prg` #endif #if defined(AMIGAOS) `lisp.run` #endif
  main executable

`lispinit.mem`
  initial memory image

`config.lsp`
  site-dependent configuration

`*.lsp`
  lisp source

`*.fas`
  lisp code, compiled by `clisp`

`*.lib`
  lisp source library information, generated and used by the `clisp` compiler

#ifdef HAVE_ENVIRONMENT

## Environment

`CLISP_LANGUAGE`
  specifies the language `clisp` uses to communicate with the user. The value may be `english`, `deutsch`, `francais` and defaults to `english`. The `-L` option can be used to override this environment variable.

  #ifdef UNIX

`HOME` and `USER`
  are used for determining the value of the function `user-homedir-pathname`. (Unix implementation only.)

  #endif #if defined(UNIX) || defined(MSDOS)

#ifdef UNIX `SHELL` (Unix implementation only)
  is used to find the interactive command interpreter called by `(shell)`. #endif #ifdef MSDOS `COMSPEC` (DOS, OS/2 implementations only)
  is used to find the command interpreter called by the function `(shell)`. #endif

  #endif #ifdef UNIX

`TERM`
  determines the screen size recognized by the pretty printer. This environment variable is also mandatory for the built-in screen editor.

  #endif #ifdef EMUNIX_PORTABEL

`TERM`
  specifies the terminal emulation `clisp` relies on. If you have ANSI.SYS loaded, possible values are `ansi`, `ansi-color-2`, `ansi-color-3` and `mono`.

`TERMCAP`
  should be set to the slashified file name of the terminal capabilities database `termcap.dat`.

  #endif #ifdef MULTIMAP_MEMORY_VIA_FILE

`TMPDIR` (Sparc implementation only)
  specifies the directory where the temporary core file is to be held.

  #endif #endif

  ## Bugs

  - The function `inspect` is not implemented. #ifdef SPVW_MIXED_BLOCKS
  - The memory management scheme is not very flexible. #endif
  - Only very few extensions from CLtL2 are supported.
  - No on-line documentation beyond `apropos` and `describe` is available. #ifdef EMUNIX
  - Stack overflow aborts the program ungracefully, with a register dump.
  - Pressing Control-C may not interrupt `clisp` in every situation.
  - Calling the function `execute` on batch files crashes the machine. #endif #ifdef UNIX_COHERENT `*keyboard-input*` does not recognize Ctrl-S and Ctrl-Q. #endif

  ## Projects

  - Writing on-line documentation.
  - Building a foreign function interface (ability to call C code directly).
  - Write `inspect`.
  - Enhance the compiler such that it can inline local functions.
  - Specify a portable set of window and graphics operations.
