Hi All. I've been working with Mike Haertel (the original author of GNU grep) for a number of months now. He is writing a new regexp matcher for use in gawk (and other places, as people desire).
The matcher is avalable on Github: https://github.com/mikehaertel/minrx. I have created a branch in the gawk repo that uses it: feature/minrx. MinRX is currently written in C++20. Mike will eventually rewrite it in C for portability. For the moment, you'll need to use gcc / g++ to build the branch. I haven't tried to mess with clang / clang++. The test suite passes completely. The new matcher is the default, so that it will be exercised. The old matchers are still available. To use them, set GAWK_GNU_MATCHERS in the environment. I will NOT make a formal release with MinRX as long as MinRX is still in C++. For now, the only way to access the code is via Git: git clone https://git.savannah.gnu.org/r/gawk.git cd gawk git checkout feature/minrx ./bootstrap.sh && ./configure && make -j && make check If you use gawk, please try this branch out. Questions, comments, and *bug reports* are welcome. Thanks, Arnold
