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