The biggest difference here is the use of a syntax extension to parse the grammar. This is something I would like to do at some point, because it can make the code nicer. Right now, macros are good, because you can use nom directly without Rust 1.0, no need for feature gates.
- buster 11y agoThat'd be nice.. i am currently contemplating to move or not. Nom does run on Rust stable, right? Although i find rust-peg super easy to use, i don't like that it's only working on nightly. A difference in performance would be another reason to switch over.. or not.. :) Anyway, thanks for this great project!
- geal 11y agoNom works on stable, but there are nice things you can do if you use the nightly, like matching on error codes with slice or box patterns ( https://github.com/Geal/nom/wiki/Error-management#with-slice-patterns https://github.com/Geal/nom/wiki/Error-management#with-slice... ) or use no_std to embed the parser as a C library ( https://github.com/Geal/nom_in_c https://github.com/Geal/nom_in_c ).
- steveklabnik 11y agoYou shouldn't need no_std specifically to embed in C anymore.
- geal 11y agoThat's nice to know, thanks!
- steveklabnik 11y agoAny time. Basically, one the runtime was removed[1], this became true. 1: Of course, all programming languages have runtimes, but once we got down to C or C++ levels of runtime, that is.
