NAME

skint − cheap and fast R7RS Scheme interpreter

SYNOPSIS

skint [OPTION]... [FILE] [ARG]...

If no FILE is given, an interactive Read-Eval-Print loop is started.

DESCRIPTION

skint is a small, self-contained interpreter for the R7RS-small Scheme language. All standard libraries are built-in; more than 100 SRFIs can be loaded from the optional external library tree.

When FILE is supplied it is executed as a Scheme script (SRFI-22 semantics) after which skint exits.

OPTIONS

−v, −−verbose

Increase output verbosity.

−q, −−quiet

Suppress non-essential messages.

−A, −−append−libdir=DIR

Append DIR to the library search path.

−I, −−prepend−libdir=DIR

Prepend DIR to the library search path.

−D, −−define−feature=NAME

Add NAME to the (features) list.

−U, −−undef−feature=NAME

Remove NAME from the (features) list.

−e, −−eval=SEXP

Evaluate and print SEXP, then continue.

−l, −−load=FILE

Load FILE and continue.

−s, −−script=FILE

Run FILE as a script (SRFI-22).

−p, −−program=FILE

Run FILE as a program (non-script mode).

−V, −−version

Show version (in SRFI 176 format) and exit.

−h, −−help

Show help and exit.

−−

Ends option processing; remaining arguments are passed to the script.

ENVIRONMENT

SKINT_LIBDIRS

Colon-separated list of directories searched for ‘.sld‘ libraries. If unset the default is ./:lib/:/usr/share/skint/lib/

FILES

/usr/share/skint/lib/

External library tree (‘.sld‘ modules) installed by make libinstall.

EXAMPLES

Interactive REPL:

skint

Interactive REPL with command line editing:

rlwrap skint

Run a script:

skint -s hello.scm arg1 arg2

Evaluate an expression:

skint -e ’(display (+ 1 2 3)) (newline)’

Load a file then enter REPL:

skint -l init.scm

EXIT STATUS

	0		successful execution
	1		syntax or runtime error
	2		command-line usage error
