GOSH(1)                         Gauche Commands                        GOSH(1)

NAME
       gosh - a Scheme script interpreter

SYNOPSIS
       gosh [-biqV] [-I path ] [-A path ] [-u module ] [-l file ] [-e expr ]
       [-E expr ] [-f flag ] [--] [ script argument ...  ]

DESCRIPTION
       Gosh is a stand-alone Scheme interpreter built on top of the Gauche
       Scheme script engine.

       When script is given, gosh loads the script, evaluating Scheme code in
       it.  Then, if the script defines a procedure named main, gosh calls it
       with a single argument which is a list of the script name and
       subsequent arguments.  When main returns an integer value, gosh exits
       with it as an exit code.  If main returns non-integer value, or an
       error is signaled during evaluation, gosh exits with exit code 70
       (EX_SOFTWARE).  See SRFI-22
       (http://srfi.schemers.org/srfi-22/srfi-22.html) for details.  If
       there's no main procedure defined in the script, gosh exits with code 0
       after loading the script file.

       If no script file is given, gosh goes into an interactive mode.  By
       default, gosh prompts the user to enter a Scheme expression, read and
       evaluates it, then prints the result, until EOF is read.  If the
       standard input is not a terminal, however, gosh doesn't print a prompt;
       it allows a user to use gosh as a filter program.  This behavior can be
       controlled by -i or -b option; see below.

OPTIONS
       Command line options are processed before loading the script file or
       entering the interactive mode.

       The options -I, -A, -u, -l, -L, -e and -E are processed in the order of
       appearance.  For example, adding a load path by -I option affects the
       -l options after it, but not the ones before it.

       -V   Prints gosh version and exits.

       -b   Batch mode.  Doesn't print prompt even the standard input is a
            terminal.  Supersedes -i.

       -i   Interactive mode.  Forces to print prompt, even the standard input
            is not a terminal.

       -q   Prevents reading the default initialization file.

       -Ipath
            Adds path in front of the load path list.

       -Apath
            Appends path to the tail of the load path list.

       -umodule
            Loads and imports module, as if "(use module )" is specified in
            the code.

       -lfile
            Loads a Scheme file file.

       -Lfile
            Like -l, but doesn't complain if file doesn't exist.

       -eexpr
            Evaluates a Scheme expression expr.

       -Eexpr
            Same as -e, except that the expr is read as if it is surrounded by
            parenthesis.

       -ptype
            Turns on the profiler.  Currently type can only be 'time'.

       -fflag
            Sets various flags.
              case-fold       uses case-insensitive reader (as in R5RS)
              load-verbose    report while loading files
              no-inline       don't inline primitive procedures and constants
                              (combined no-inline-globals, no-inline-locals,
            and
                              no-inline-constants.)
              no-inline-globals don't inline global procedures.
              no-inline-locals  don't inline local procedures.
              no-inline-constants don't inline constants.
              no-post-inline-pass don't run post-inline optimization pass.

       -Ffeature
            Makes feature available in cond-expand forms.

       --   Specifies that there are no more options.  If there are more
            arguments after this, they are taken as script file name and its
            arguments.

ENVIRONMENT
       GAUCHE_LOAD_PATH
       A colon separated list of the load paths.
              The paths are appended before the system default load paths.

       GAUCHE_DYNLOAD_PATH
       A colon separated list of the load paths for dynamically loaded
              objects.  The paths are appended before the system default load
              paths.
