fdscript1

Usage

Overview

fdscript starts an fdscript interpreter either interactively or by reading commands from the file filename. The scheme variables args and nargs are bound to the specified arguments provided on the command line. The interpreter is interactive if either filename is not given or is either a single dash ("-") or a single dot ("."). In either case, the files or modules specified by the other options are processed first, as are any Scheme variable assignments specified on the command line.

If filename is provided and defines a Scheme procedure main, it is applied to the given arguments after filename has been read.

The additional arguments are interpreted with two special conventions. An argument specified by a single dollar sign ($) is bound to the entire standard input, read as a string; an argument specified by a single dash (-), reads a series of lisp objects from the standard input and binds the corresponding argument to those objects as a choice.

If filename is a single dash (-), the interactive read-eval-print loop will proceed without any prompts, simply reading values and printing results; if the argument is a single period ("."), a prompt will be displayed but command line arguments after the period will be processed into args Finally, if there is no filename argument, a prompt will be issued when the interpreter is ready for a result and (if available) the GNU readline commands will be available for input editing.
