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
#!${exec_prefix}/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).
