| 2 | |
| 3 | [Documentation](http://alexcrichton.com/proc-macro2) |
| 4 | |
| 5 | A small shim over the `proc_macro` crate intended to multiplex the current |
| 6 | stable interface (as of 2017-05-19) and the [upcoming richer |
| 7 | interface][upcoming]. |
| 8 | |
| 9 | [upcoming]: https://github.com/rust-lang/rust/pull/40939 |
| 10 | |
| 11 | The upcoming support has features like: |
| 12 | |
| 13 | * Span information on tokens |
| 14 | * No need to go in/out through strings |
| 15 | * Structured input/output |
| 16 | |
| 17 | My hope is that libraries ported to `proc_macro2` will be trivial to port to the |
| 18 | real `proc_macro` crate once the support on nightly is stabilize. |
| 19 | |
| 20 | This crate is still very much a work in progress |
