Replacement Parser

Edward parser combinators for parsing replacement strings.

procedure parse-replace

Parse a replacement string within text enclosed with the delimiter delim. While the combinator does not parse the enclosed character, it ensures that this delim character is escaped (using a \) within the replacement.

Refer to the documentation of the ed substitute command for more information on special character support within the replacement. All of these special characters can also be escaped.

(parse-replace delim)

Replacement Procedures

Procedures for performing replacements using a parsed replacement string.

procedure regex-replace

Replace nth occurrence of regex in str with subst. If nth is zero, all occurrences are replaced. Returns two results: The string after performing all replacement and a boolean indicating if any replacements were successfully performed. The regex must be created using make-regex, while the replacement string subst must be parsed using parse-replace.
