This crate provides an attribute macro for making the visibility of the macro_rules!
macro the same as other items.
The visibility of declarative macros is not consistent with the behavior of other items in rust, necessitating the use of #[macro_use]
and #[macro_export]
instead of pub
or pub(...)
, such inconsistencies make the mental burden and cognitive cost significant. Now with this crate, you are allowed to use #[macro_v]
or #[macro_v(pub)]
or #[macro_v(pub(...))]
on any macro_rules!
macro, giving declarative macros the same visibility as other items, no more writing confusing #[macro_use]
and #[macro_export]
.
Inspired by macro-vis and even named after a part of it, but there are two problems of macro-vis
:
you have to add #![allow(uncommon_codepoints)]
.
the modified macro is shown in the documentation as a function instead of a macro.
To solve these two problems, I've reimplemented an attribute macro.
It's very simple, see the code:
```rust
macrorules! examplemacro { () => {}; } ```
... will expand to this:
```rust
macrorules! _examplemacro2228885075611141983 { () => {}; }
pub(crate) use _examplemacro2228885075611141983 as examplemacro; ```
If you are using #[macro_v(pub)]
, then the expanded code will then have #[macro_export]
added to it:
```rust
macrorules! _examplemacro2228885075611141983 { () => {}; }
pub use _examplemacro2228885075611141983 as examplemacro; ```
But because of using #[doc(hidden)]
, you must use #[doc(inline)]
attribute when re-exporting, otherwise re-exported macro won't be visible in the document. When using #[macro_v]
, #[doc(inline)]
will be added automatically, but if you want to re-export manually, you must remember to add #[doc(inline)]
, which is the only problem.
