| Report Configuration Options for PCRE |
| } |
| \description{ |
| Report some of the configuration options of the version of PCRE in use |
| in this \R session. |
| } |
| \usage{ |
| pcre_config() |
| } |
| \value{ |
| A named logical vector, currently with elements |
| \item{UTF-8}{Support for UTF-8 inputs. Required.} |
| \item{Unicode properties}{Support for \samp{\p{xx}} and \samp{\P{xx}} |
| in regular expressions. Desirable and used by some CRAN packages. |
| As of PCRE2, always present with support for UTF-8.} |
| \item{JIT}{Support for just-in-time compilation. Desirable for speed |
| (but only available as a compile-time option on certain |
| architectures, and may be unused as unreliable on some of those, |
| e.g.\sspace{}\code{arm64}).} |
| \item{stack}{Does match recursion use a stack (\code{TRUE}, the default |
| for PCRE1 and PCRE2 older than 10.30) or a heap? See the discussion at |
| \url{https://www.pcre.org/original/doc/html/pcrestack.html} (Added |
| in \R 3.4.0.). No longer relevant and always \code{FALSE} in PCRE2 |
| since version 10.30 which no longer uses function recursion to remember |
| backtracking positions.} |
