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.
−?, −−help
Shows the help prompt without running the ECL.
−v, −−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.
−−dir directory
Use directory as a system directory.
−−load file
Load source file before loading the .rc file and starting the toplevel.
−−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.
−−eval file
Evaluate the file before loading the .rc file and starting the Top Level.
−−rc
Load configuration files at startup (default).
−−norc
Do not load configuration files at startup.
−−c−stack size
Set C stack size in kilobytes for C compiler.
−−lisp−stack size
Set stack size in kilobytes for bytecodes interpreter.
−−heap−stack size
Set heap size in kilobytes.
−−frame−stack size
Set frame size in kilobytes for runtime control structures.
−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 hfile
When compiling name the intermediary *.h file 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 |
Short for quiet -- produce less notes. |
−−compile file
Translates file to C and invokes the local C compiler to produce a native code program.
−−link file+
Create standalone executable from Lisp files file+.
−−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.
−−encoding encoding
Specify the external encoding for standard input, output, trace and error.
−−trap-fpe
Make ECL debugger catch floating point exception.
−−no-trap-fpe
Disable ECL debugger floating point exception catching.
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 maintainers of ECL are Daniel KochmaÅski and Marius Gerbershagen, who can be reached at the ECL mailing list.
˜/.ecl, ˜/.eclrc
Default initialization files loaded at startup unless the option −−norc is provided (if they exist).
ANSI Common Lisp standard X3.226-1994
