Framework for procedural macroes in Rust1 year, 3 months ago
From the translator
Procedural macroes — one of the most expected Rust features. At the moment it is possible to write procedural macroes only under the unstable version of the compiler though there are several containers, like syntex, allowing to do a limited kodogeneration within the stable compiler. However it especially does not facilitate a situation as the interface to AST remains unstable, and though authors of syntex try to go in step with night assemblies, sometimes there are feyla because of changes in structure of AST.
In it the blog a post one of participants of core team — Nick Cameron — shared the vision of the future of procedural macroes. Though the post is complete of technical details on compiler interiors, it seemed to me that to a habrasoobshchestvo can be interesting to glance a little behind the scenes of development of Rust.
Framework for procedural macroes
In this post I will tell how, in my opinion, procedural macroes have to look. I already told about syntax in other post and when we publish API for procedural macroes, I will write a post and about it. I already described a number of changes in system of macroes so here I in something will repeat (partly contradicting last post), but I will disclose more details.
