#lang racket/base (require racket/file math/number-theory) (with-output-to-file "d:/big-numbers.rkt" (λ () (define x (factorial 5000)) (displayln "#lang racket") (displayln "(define bignumber-list (list ") (for ([n 2]) (displayln x)) (display "))") (flush-output))) Result on my machine: http://postimg.org/image/5xqo3bcvv/full/ 'Reindent All' (Ctrl+I) makes view normal. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
