NAME

       gsi - Gambit-C Scheme Interpreter and Compiler

SYNOPSIS

       gsi [ -:arg,... ] [ -f ] [ -v ] [[-] [ -e ] [ file ]]...
       gsc [options] [files]

       gsc-script,  gsi-script,  scheme-ieee-1178-1990, scheme-r4rs, scheme-srfi-0, six, and six-
       script: currently synonyms for gsi.

       scheme-r5rs is registered in the Debian alternatives system and can be configured to point
       at gsi.

DESCRIPTION

       This manual page documents briefly the gsi and gsc commands.

       The  Gambit-C  programming  system  is  a full implementation of the Scheme language which
       conforms to the R4RS, R5RS, and IEEE Scheme standards.  It consists of two main  programs:
       gsi,  the  Gambit  Scheme  interpreter,  and  gsc,  the  Gambit Scheme to C compiler.  The
       interpreter provides an interactive environment with a debugger, while  the  compiler  can
       produce  stand-alone  executables  or  modules  which can be linked or loaded at run time.
       Interpreted code and compiled code can be freely mixed.  C  modules  can  be  linked  with
       Scheme modules.

       The  interpreter  is  executed  in  interactive mode when no file or `-' or `-e' option is
       given on the command line.  When at least one file or `-' or `-e' option  is  present  the
       interpreter is executed in batch mode.

       Entering ,q or (exit) at the interpreter's command prompt will exit the interpreter.

       In  batch  mode the command line arguments denote files to be loaded, REPL interactions to
       start (`-' option), and expressions to be evaluated (`-e' option).  Note that the `-'  and
       `-e' options can be interspersed with the files on the command line and can occur multiple
       times.  The interpreter processes the command line arguments from left to  right,  loading
       files  with  the  `load' procedure and evaluating expressions with the `eval' procedure in
       the global interaction environment.  After this processing the interpreter exits.

       gsc-cc-o.bat is a script called by gsc to generate object files  during  compilation.   It
       takes its data from environment variables and is not intended for user interaction.

OPTIONS

       A summary of options is included below.  For a complete description, see the Info files.

       -      Initiate  a  REPL  at  this  point.  (Continue  by  issuing a ,(c 0) command at the
              interpreter prompt)

       -:     Comma separated list of run-time options

       -e     Evaluate an expression.

       -f     Skip initialization file.

       -v     Show version of program.

SEE ALSO

       The documentation for these programs is arguably too extensive to cover  with  man  pages.
       Only the common command line options are given here.  The programs are documented fully in
       Gambit-C,  available  on-line  at  the  Gambit-C  Homepage.   Once  package  gambc-doc  is
       installed,  this  200+  page document is available via the Info system (info gambit-c), in
       html via doc-base, or as files in /usr/share/doc/gambc (html, pdf, txt).

       The Debian package r5rs-doc provides the Revised(5) Report  on  the  Algorithmic  Language
       Scheme  in  several formats.  That document is the defining description of the programming
       language Scheme.
