PCRE2 Bindings for Chez Scheme

This library provides Chez Scheme bindings for (a subset of) PCRE2 (UTF-8).

Functions

(pcre2-compile pattern options)

Compile the given string pattern for use with pcre2-match. The compiled code allocated by PCRE2 is automatically freed when the returned object becomes inaccessible from Scheme.

(pcre2-match pattern string offset options)

Match the compiled pattern to the passed string starting at offset. Returns a match data block object that may be manipulated using the following functions, or #f if no match was made.

(pcre2-get-match-count match-data)

Return the number of matches in the match data block.

(pcre2-get-match-groupcount match-data)

Return the number of groups (possibly null) in the match data block.

(pcre2-get-match-group match-data n)

Return the n-th group in the given match data block. If that group did not match, #f is returned.

(pcre2-get-match-groups match-data)

Return all groups in the given match data block (including null groups) as a list.

Requirements

Ensure that PCRE2 is accessible as libpcre2-8.so.
