pcre2-10.33

[Douglas R. Reno]

New minor version

[Bruce Dubbs]

Version 10.33-RC1 16-April-2019

Yet more bugfixes, tidies, and a few enhancements, summarized here (see ChangeLog for the full list):

1. Callouts from pcre2_substitute() are now available.

2. The POSIX functions are now all called pcre2_regcomp() etc., with wrapper

functions that use the standard POSIX names. However, in pcre2posix.h the POSIX names are defined as macros. This should help avoid linking with the wrong library in some environments, while still exporting the POSIX names for pre-existing programs that use them.

3. Some new options:

(a) PCRE2_EXTRA_ESCAPED_CR_IS_LF makes \r behave as \n.

(b) PCRE2_EXTRA_ALT_BSUX enables support for ECMAScript 6's \u{hh...}

construct.

(c) PCRE2_COPY_MATCHED_SUBJECT causes a copy of a matched subject to be

made, instead of just remembering a pointer.

4. Some new Perl features:

(a) Perl 5.28's experimental alphabetic names for atomic groups and

lookaround assertions, for example, (*pla:...) and (*atomic:...).

(b) The new Perl "script run" features (*script_run:...) and

(*atomic_script_run:...) aka (*sr:...) and (*asr:...).

(c) When PCRE2_UTF is set, allow non-ASCII letters and decimal digits in

capture group names.

5. --disable-percent-zt disables the use of %zu and %td in formatting strings

in pcre2test. They were already automatically disabled for VC and older C compilers.

6. Some changes related to callouts in pcre2grep:

(a) Support for running an external program under VMS has been added, in

addition to Windows and fork() support.

(b) --disable-pcre2grep-callout-fork restricts the callout support in

to the inbuilt echo facility.
