NAME
guile - The GNU Project Extension Language
SYNOPSIS
guile [-L DIRECTORY] [-l FILE] [-e FUNCTION] [\] [-c EXPR] [-s SCRIPT]
[--] [SCRIPT [ARGs for SCRIPT]]
Only the most useful options are listed here; see below for the
remainder.
DESCRIPTION
GNU Guile is an implementation of the Scheme programming language. It
extends the R5RS and R6RS language standards, providing additional
features necessary for real-world use.
Guile works well for interactive use, basic scripting, and extension
of larger applications, as well as for stand-alone Scheme application
development.
The guile executable itself provides a stand-alone interactive
compiler and run-time for Scheme programs, both for interactive use
and for executing Scheme scripts or programs.
This manual page provides only brief instruction in invoking guile
from the command line. Please consult the Guile info documentation
for more information, (type info "(guile)Invoking Guile" at a command
prompt).
OPTIONS
-L DIRECTORY
Add DIRECTORY to the front of Guile's module load path.
-l FILE
Load Scheme source code from FILE.
-e FUNCTION
After reading SCRIPT, apply FUNCTION to command-line arguments.
Note that FUNCTION is evaluated, so, for example, (@ (my-module)
my-proc) is valid here.
\ The "meta switch", used to work around limitations in #! scripts.
See "The Meta Switch" in the texinfo documentation for more
details.
-- Stop argument processing, and start guile in interactive mode.
-c EXPR
Stop argument processing, and evaluate EXPR as a Scheme
expression.

-s SCRIPT-FILE
Load Scheme source from SCRIPT-FILE and execute as a script.
Note that in many cases it is not necessary to use -s; one may
invoke guile simply as guile SCRIPT-FILE ARG...
-ds Carry out -s SCRIPT at this point in the option sequence. Note
that this argument must be used in conjunction with -s.
--debug
Start guile with the debugging VM. By default, debugging is on
when guile is invoked interactively; it is off otherwise.
--no-debug
Start guile without the debugging VM, even if guile is being run
interactively.
--auto-compile
Compile source files automatically (default behavior).
--no-auto-compile
Disable automatic source file compilation.
--listen[=P]
Listen on a port or socket for remote REPL connections. See the
manual for more details.
--use-srfi=N,M...
Load SRFI extensions N, M, etc. For example,
--use-srfi=8,13.
-x EXTENSION
Add EXTENSION to the guile load extension list.
-h, --help
Describe command-line options and exit.
-v, --version
Display guile version and exit.
-q In interactive mode, suppress loading the user's initialization
file, ~/.guile.
ENVIRONMENT
GUILE_LOAD_PATH
If $GUILE_LOAD_PATH is set before guile is started, its value is
used to augment the path to search for Scheme files when loading.
It should be a colon-separated list of directories, which will be
prefixed to the default %load-path.

GUILE_LOAD_COMPILED_PATH
If $GUILE_LOAD_COMPILED_PATH is set before guile is started, its
value is used to augment the path to search for compiled Scheme
files (.go files) when loading. It should be a colon-separated
list of directories, which will be prefixed to the default
%load-compiled-path.
FILES
~/.guile
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.
REPORTING BUGS
There is a mailing list, bug-guile@gnu.org, for reporting Guile bugs
and fixes. But before reporting something as a bug, please try to be
sure that it really is a bug, not a misunderstanding or a deliberate
feature. We ask you to read the section ``Reporting Bugs'' in the
Guile reference manual (or Info system) for hints on how and when to
report bugs. Also, include the version number of the Guile you are
running in every bug report that you send in. Bugs tend actually to
get fixed if they can be isolated, so it is in your interest to report
them in such a way that they can be easily reproduced.
