Macro documentation is sorely lacking #294
Description
Activity
For procedural macros, I have a tiny crate here:
https://github.com/sparkles-web/sparkles/blob/master/example-app/src/main.rs
https://github.com/sparkles-web/sparkles/blob/master/sparkles-macros/src/lib.rs
Proc macro documentation is a lot better.
Macros-by-example are now significantly improved via #511.
Macro invocation sites, grammar, and more was added in #458.
Proc-macros were done in #412.
I believe the listed RFCs are covered now, so closing this issue. There's likely more that can be added about macros, but new issues should probably be opened for specific shortcomings.
Our macro documentation currently has slim documentation on macros by example, and nearly no documentation on procedural macros. Additionally, there is almost no documentation about macro invocation, such as where they are allowed or not allowed. Macros are a language feature like any other, and should be fully documented.
The following RFCs should be fully documented, at least:
RFC 0085
RFC 0378
RFC 0453
RFC 0550
RFC 0873
RFC 1681
