Bug ID: 2503
Summary: Documentation references a (?J) not explained anywhere
Product: PCRE
Version: N/A
Hardware: All
OS: All
Status: NEW
Severity: bug
Priority: medium
Component: Documentation
Assignee: ph10@???
Reporter: php4fan@???
CC: pcre-dev@???
https://www.pcre.org/current/doc/html/pcre2pattern.html
Where it says:
"""
The duplicate name constraint can be disabled by setting the PCRE2_DUPNAMES
option at compile time, OR BY THE USE OF (?J) within the pattern
"""
(emphasys added)
So I searched for any occurrence of "?J" and it doesn't appear anywhere else.
It's not clear by that sentence alone how "(?J) within the pattern" is supposed
to be used. Not only there is no explanation but it doesn't appear in any of
the examples.
