文本
Copy it and replace filenames, paths, or keywords as needed.
命令示例
Start an interactive RLISP session
rlisp
Load and execute an RLISP source file
rlisp < [program.red]
Use a custom heap size (in megabytes)
rlisp -K [256]
Suppress banner and garbage-collector chatter
rlisp -q
Set a Lisp variable from the command line
rlisp -D [name]=[value]
说明
RLISP is an ALGOL-like surface syntax for Standard Lisp, used internally by the REDUCE computer algebra system. It provides Lisp semantics — symbolic expressions, lists, atoms, recursion — but with a more readable infix and keyword syntax (begin/end, if/then/else, for, while) instead of S-expressions. When invoked, rlisp starts an interactive read-eval-print loop. Statements are terminated by a semicolon (;) for normal output, or by a dollar sign ($) to suppress the printed result. From inside REDUCE you can switch to RLISP/symbolic mode with symbolic; and back with algebraic;. The binary is part of REDUCE and is normally built on top of either CSL (Codemist Standard Lisp) or PSL (Portable Standard Lisp); the available command-line options reflect the underlying Lisp engine.
参数
