Sourceval filter : (char -> bool) -> string -> string

filter p s creates a copy of s containing the characters of s such that p c = true,

Sourceval lfindi : string -> (char -> bool) -> int option

lfindi s p retrieves the first index of a character verifying predicate p. None otherwise

Sourceval remove_char : char -> string -> string

remove_char c s creates a copy of s without any occurrence of c

Sourceval remove_newline : string -> string

remove_newline s creates a copy of s without the newline character '\n'
