[racket] Locating substring with reserved characters
Hi all,
I'm trying to locate a substring that I want to be treated just as a string
rather than regexpr notation. The used strings are dynamic and there's no
control over their content. This is propably something simple, but I can't
seem to get it right.
Any ideas?
#lang racket
(regexp-match-positions* (pregexp "5 (+ 1 2 3)") "((named-lambda (plus x y)
(+ x y)) 5 (+ 1 2 3))")
;>> error: regexp: `+' follows nothing in pattern
