NAME
guile - a Scheme interpreter
SYNOPSIS
guile [-q] [-ds] [--help] [--version] [--emacs] [--debug]
[-l FILE] [-e FUNCTION] []
[-c EXPR] [-s SCRIPT] [--]
DESCRIPTION
GNU Guile is an interpreter for the Scheme programming language. It
implements R5RS, providing additional features
necessary for real-world use. It is extremely simple to embed guile
into a C program, calling C from Scheme and Scheme from C. Guile's
design makes it very suitable for use as an "extension" or "glue"
language, but it also works well as a stand-alone scheme development
environment.
The
guile
executable itself provides a stand-alone interpreter for scheme
programs, for either interactive use or executing scripts.
This manpage provides only brief instruction in invoking
guile
from the command line. Please consult the guile info documentation
(type
info guile
at a command prompt) for more information. There is also a tutorial
(info guile-tut)
available.
OPTIONS
- -l
-
Load scheme source code from file.
- -e
-
After reading script, apply FUNCTION to command-line arguments
- -ds
-
do -s SCRIPT at this point (note that this argument must be used in
conjuction with -s)
- --help
-
Describe command line options and exit
- --debug
-
Start guile with debugging evaluator and backtraces enabled
(useful for debugging guile scripts)
- --version
-
Display guile version and exit.
- --emacs
-
Enable emacs protocol for use from within emacs (experimental)
- --
-
Stop argument processing, start guile in interactive mode.
- -c
-
Stop argument processing, evaluate EXPR as a scheme expression.
- -s
-
Load Scheme source from SCRIPT-FILE and execute as a script.
ENVIRONMENT
- GUILE_LOAD_PATH
-
If
$GUILE_LOAD_PATH
is set, its value is used to agument the path to search for scheme
files when loading. It should be a colon separated list of
directories which will be prepended to the default %load-path.
FILES
~/.guile
is a guile script that is executed before any other processing occurs.
For example, the following .guile activates guile's readline
interface:
-
(use-modules (ice-9 readline))
-
(activate-readline)
SEE ALSO
The full documentation for guile is maintained as a Texinfo manual. If
the info and guile programs are properly installed at your site, the
command
-
info guile
should give you access to the complete manual.
http://www.schemers.org provides a general introduction to the
Scheme language.

is GNU software. Guile is originally based on Aubrey Jaffer's
SCM interpreter, and is the work of many individuals.
