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).
