🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🎉 Hooray, Peppa PEG v1.15.0 is now released! 🎉 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷 🐷

1. Do you know there is a formal Peppa PEG specification now? Check it out: https://www.soasme.com/PeppaPEG/spec.html.

2. Back reference is a useful feature for capturing a previously matched string for later use. Check it out: https://www.soasme.com/PeppaPEG/spec.html#back-reference

3. Have you tried mkdir build && cd build && cmake .. && make && make install? Peppa PEG can now be installed as a shared library and a command-line utility. The utility is helpful when developing a new grammar. Check it out: https://github.com/soasme/PeppaPEG#installation

4. Want to see more examples? Check this new one: Toml v1.0 specification in Peppa PEG.
