       gosh - a Scheme script interpreter


       gosh  [-biqV] [-I path ] [-A path ] [-u module ] [-l file ] [-L file ] [-e expr ] [-E expr
       ] [-m module ] [-f flag ] [-F feature ] [-p type ] [-r standard ] [--] [  script  argument
       ...  ]


       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
       ( 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.


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

       -q   Prevents reading the default initialization file.

            Adds path in front of the load path list.

            Appends path to the tail of the load path list.

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

            Loads a Scheme file file.

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

            Evaluates a Scheme expression expr.

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

            Turns on the profiler.  Type can be either 'time' or 'load'.

            When  the script file is given, this option specifies the name of the module in which
            the "main" procedure is defined.  The default is "user".

            Starts gosh with the default environment defined in RnRS, where n  is  determined  by
            standard.  Currently, only 7 is the valid value of standard.

            Sets various flags.
              case-fold       use case-insensitive reader (as in R5RS)
              load-verbose    report while loading files
              include-verbose report while including 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.
              no-lambda-lifting-pass don't run lambda lifting optimization pass.
              no-source-info  don't retain source information.
              warn-legacy-syntax print warning when legacy Gauche syntax
                              is encountered.
              test            assume being run in the build tree; tries to
                              load files from the current build instead of
                              installation directories.  Useful to test
                              the build without installation.

            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.

              The paths are appended before the system default load paths.

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