By default, on non-Windows systems, pcre2grep supports the use of call-
outs with string arguments within the patterns it is matching, in order
to run external scripts. For details, see the pcre2grep documentation.
This support can be disabled by adding --disable-pcre2grep-callout to
the configure command.
By default pcre2grep supports the use of callouts with string arguments
within the patterns it is matching. There are two kinds: one that gen-
erates output using local code, and another that calls an external pro-
gram or script. If --disable-pcre2grep-callout-fork is added to the
configure command, only the first kind of callout is supported; if
--disable-pcre2grep-callout is used, all callouts are completely
ignored. For more details of pcre2grep callouts, see the pcre2grep doc-
umentation.
