SYNOPSIS

       ecl [-? | --help]
       [--dir dir] [--load file] [--shell file] [--eval expr]
       [--norc] [--hp | --nohp]
       [--debug | --nodevbug]

       [--heap-size size] [--frame-stack size]
       [[-o ofile] [-c [cfile]] [-h [hfile]] [--data [datafile]]
        [-s] [-q] --compile file]

       DEPRECATION  NOTE:  one-dash  versions  of long flags(e.g. -eval or -data) are deprecated; you should use
       two-dash versions (e.g. --eval or --data) now.

DESCRIPTION

       ECL (Embeddable Common-Lisp) is an interpreter of the Common-Lisp language as described in the X3J13 Ansi
       specification,  featuring  CLOS (Common-Lisp Object System), conditions, loops, etc. plus a translator to
       C, which can produce standalone executables.

       ECL supports the operating systems Linux, FreeBSD, NetBSD, OpenBSD, OS X, Solaris and Windows, running on
       top of the Intel, Sparc, Alpha, PowerPC and ARM processors.

       The current ECL implementation features:

       •      A bytecode compiler and interpreter.

       •      Compiles Lisp also with any C/C++ compiler

       •      Can build standalone executables and libraries

       •      ASDF, Sockets, Gray streams, MOP, and other useful components

       •      Extremely portable

       •      A reasonable license

       ecl without any argument starts the interactive lisp session.

OPTIONS

-?, --help
Shows the help prompt without running the ECL.

--norc Do not load configuration files at startup.

--version Prints the current version of ECL, without running the ECL.

-debug Turned on by default, this enables the debugging in the setup phase, so that you can debug your
files.

--nodebug Run without debugging setup phase, meaning that errors prevent ECL from starting up.

--eval file
Evaluate the file before loading the .rc file and starting the Top Level.

--shell file
Executes the given file and exits, without providing a read-eval-print loop. If you want to
use lisp as a scripting language, you can write #!${exec_prefix}/bin/ecl --shell on the first
line of the file to be executed, and then ECL will be automatically invoked.

--load file
Load source file before loading the .rc file and starting the Top Level.

--dir directory
Use directory as a system directory.

--heap-size size
Specify heap size in kilobytes.

--lisp-stack size
Specify stack size in kilobytes for lisp system.

--frame-stack size
Specify frame stack size in kilobytes.

--c-stack size
Specify stack size in kilobytes for C compiler.

--trap-fpe
Make ECL debugger catch floating point exception.

--no-trap-fpe
Make ECL debugger not catch floating point exception.

--encoding encoding
Specify the external encoding for standard input, output, trace and error.

--input-encoding encoding
Specify the external encoding for standard input.

--output-encoding encoding
Specify the external encoding for standard output.

--error-encoding encoding
Specify the external encoding for standard error.

-o file Provide the output target file for compilation.

-c cfile When compiling name the intermediary C file cfile and do not delete it afterwards.

-h cfile When compiling name the intermediary C file cfile and do not delete it afterwards.

--data [datafile]
Dumps compiler data into datafile or, if not supplied, into a file named after the source file,
but with .data as extension.

--compile file
Translates file to C and invokes the local C compiler to produce a native code program.

-q Short for quiet - produce less notes.

--hp This option is deprecated and doesn't do anything.

--nodp This option is deprecated and doesn't do anything.

-s Produce a linkable object file. It cannot be loaded with load, but it can be used to build
libraries or standalone executable programs.

AUTHORS

The original version was developed by Giuseppe Attardi starting from the Kyoto Common Lisp
implementation by Taiichi Yuasa, Masami Hagiya. Further development was lead by Juan Jose Garcia
Ripoll. The current maintainer of ECL is Daniel Kochmański, who can be reached at the ECL mailing
list.

FILES

       ~/.ecl, ~/.eclrc
              Default  initialization  files  loaded  at startup unless the option --norc is provided.  (if they
              exist).

BUGS

       Unfortunately it is possible that there are some bugs in the program.  In case you find any  bug,  please
       report  it  as  an  issue  (after  making  sure that it hasn't been reported or fixed) to official gitlab
       repository: https://gitlab.com/embeddable-common-lisp/ecl/issues .
