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).
