NAME
ecl - Embeddable Common LISP
SYNOPSIS
ecl [-dir dir] [-load
file] [-eval expr]
[-compile file
[-o
ofile] [-c [cfile]] [-h [hfile]]
[-data [datafile]] [-s] [-q]]
DESCRIPTION
ECL stands for Embeddable Common-Lisp. The ECL project is an
effort to modernize Giuseppe Attardi's ECL environment to produce
an implementation of the Common-Lisp language which complies to the
ANSI X3J13 definition of the language.
The current ECL implementation features:
- *
- A bytecodes compiler and interpreter.
- *
- A translator to C.
- *
- An interface to foreign functions.
- *
- A dynamic loader.
- *
- The possibility to build standalone executables.
- *
- The Common-Lisp Object System (CLOS).
- *
- Conditions and restarts for handling errors.
- *
- Sockets as ordinary streams.
- *
- The Gnu Multiprecision library for fast bignum operations.
- *
- A simple conservative mark & sweep garbage collector.
- *
- The Boehm-Weiser garbage collector.
ecl without any argument gives you the interactive lisp.
OPTIONS
- -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 #!/usr/bin/ecl -shell on the first
line of the file to be executed, and then ECL will be automatically
invoked.
- -norc
- Do not try to load the file ~/.eclrc at startup.
- -dir
- Use dir as system directory.
- -load file
- Loads file before entering the read-eval-print loop.
- -eval expr
- Evaluates expr before entering the read-eval-print loop.
- -compile file
- Translates file to C and invokes the local C compiler to
produce a shared library with .fas as extension per default.
- -o ofile
- When compiling file name the resulting shared library
ofile.
- -c cfile
- When compiling name the intermediary C file cfile and do
not delete it afterwards.
- -h hfile
- When compiling name the intermediary C header hfile 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.
- -s
- Produce a linkable object file. It cannot be loaded with load,
but it can be used to build libraries or standalone executable
programs.
- -q
- Produce less notes when compiling.
The options -load, -shell, and -eval may
appear any number of times, and they are combined and processed
from left to right.
AUTHORS
The original version was developed by Giuseppe
Attardi starting from the Kyoto Common Lisp implementation by
Taiichi Yuasa and Masami Hagiya. The current maintainer of ECL is
Juan Jose Garcia Ripoll, 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).
