NAME

       gsi - Gambit 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 briefly documents the gsi and gsc commands.

       The  Gambit  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 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.

       Entering ,? at the interpreter's command prompt will display a list of special commands.

       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 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, available on-line at the Gambit Homepage.  Once package gambdoc is installed, this
       200+ page document is available via the Info system (info gambit), in html  via  doc-base,
       or as files in /usr/share/doc/gambit (html, pdf, txt).
