pcre

This package provides a CGo-free port of the PCRE2 regular expression library. The lib directory contains source code automatically translated from PCRE2's C source. This package wraps that code and provides an interface as close as possible to Go's stdlib regexp package

Supported GOOS/GOARCH:

linux/amd64
linux/386
linux/arm64
linux/arm
linux/riscv64

More OS support is planned.

How to transpile pcre2

In order to transpile pcre2, a Go and C compiler (preferably GCC) will be needed.

First, install ccgo
Then, download the pcre source code. It can be found here: https://github.com/PCRE2Project/pcre2.
Once downloaded, cd into the source directory
Run ./configure. If cross-compiling, provide the path to the cross-compiler in the CC variable, and set --target to the target architecture.
When it completes, there should be a Makefile in the directory.
Run ccgo -compiledb pcre.json make. Do not add -j arguments to the make command.
Run the following command (replace items in triangle brackets):

CC=/usr/bin/gcc ccgo -o pcre2_<os>_<arch>.go -pkgname lib -trace-translation-units -export-externs X -export-defines D -export-fields F -export-structs S -export-typedefs T pcre.json .libs/libpcre2-8.a

If cross-compiling, set the CCGO_CC variable to to path of the cross-compiler, and the CCGO_AR variable to the path of the cross-compiler's ar binary. Also, set TARGET_GOARCH to the GOARCH you're targeting and TARGET_GOOS to the OS you're targeting.
Once the command completes, two go files will be created. One will start with pcre2, the other with capi. Copy both of these to the lib directory in this repo.
