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.
