NimbleParsec - a simple and fast parser combinator for Elixir

[OvermindDL1]

It turns out that concatenating strings on the BEAM is very slow and requires lots of copying.

Yeah definitely should be outputting IOlists, even with ExSpirit. ^.^;

From my experience in the last few days, NimbleParsec seems to be ready to be used for real projects. It’s the ideal option for those who need to parse context-free languages, and with some postprocessing steps it can be used to help parse some context-sensitive ones. I don’t believe I’ve found any bug while using it for Makeup.

I’m really curious about when it will be able to parse context-sensitive languages, then it can fully replace ExSpirit and I can deprecate it (less stuff for me to manage/update, the better!).

Thanks to @josevalim for writing this great library and for all the help and to @OvermindDL1 who’s written ExSpirit, without which Makeup would have never been written. Although quite slow, ExSpirit is way faster than almost anything out there and is still the only Elixir parser library that supports parsing context-sensitive languages.

Heh thanks, it was birthed because I needed it and nothing else out supported the features I needed. ^.^

I really want NimbleParsec to replace it, needs a few more features to be able to do that though.
