Implement `#[macro_export(local_inner_macros)]` (a solution for the macro helper import problem) #51496

petrochenkov · 2018-06-11T13:30:24Z

Implement a solution for the macro helper issue discussed in #35896 as described in #35896 (comment).

Macros exported from libraries can be marked with #[macro_export(local_inner_macros)] and this annotation changes how nested macros in them are resolved.

If we have a fn-like macro call ident!(...) and ident comes from a macro_rules! macro marked with #[macro_export(local_inner_macros)] then it's replaced with $crate::ident!(...) and resolved as such ($crate gets the same context as ident).

I've added only a basic test, if you are interested in some test cases, please tell! I'll add them as well.

There's one subtle detail that affects how we treat the nom-like cases.

If we have a macro call using a macro variable, like $var!(...) where $var ultimately means ident, then we check whether that ident comes from a macro_helper_hack macro, not the macro call $var!(...) itself.

// Library crate
#[macro_export(macro_helper_hack)]
macro_rules! public {
    ($helper: ident) => {
        $helper!();
    }
}

// User crate
// `my_helper` is not affected by the macro helper hack (not changed to `$crate::my_helper`) and is resolved in the user crate, not library crate
public!(my_helper);

The primary alternative is to determine whether the change is applicable using context of the macro call $var!() rather than context of ident.
In that case my_helper would be resolved in the library crate.

Currently building locally to play around with this, but I think this does the trick. Grabbing the span from the ident is the right behavior (as opposed to from the macro call).

petrochenkov · 2018-06-11T15:29:03Z

src/libsyntax/feature_gate.rs

+        if attr.check_name("macro_export") {
+            if let Some(content) = attr.meta_item_list() {
+                if attr::list_contains_name(&content, "macro_helper_hack") {
+                    gate_feature_post!(&self, macro_helper_hack, attr.span,


Well, this must be a mistake, the attribute shouldn't be gated at the library side, but rather the effect should be enabled if feature(use_extern_macros) is enabled on the use site or stabilized.

I was about to write the same thing. This should never happen:

error[E0658]: `macro_helper_hack` in `macro_export` is experimental (see issue #35896) --> serde-json/src/macros.rs:69:1 | 69 | #[macro_export(macro_helper_hack)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = help: add #![feature(macro_helper_hack)] to the crate attributes to enable

If not building with use_extern_macros, the macro_helper_hack should have no effect and should be ignored as it has been on all past stable compilers.

dtolnay · 2018-06-11T17:07:36Z

Overall I found that this PR works incredibly well. I tested it against some of my nastiest macro code and it behaved as desired every time, with nom-style passing of macro names across crates and everything.

The one exception I found was it seems macro_export(macro_helper_hack) macros cannot be invoked from inside of their own crate:

#![feature(use_extern_macros, macro_helper_hack)]

#[macro_export(macro_helper_hack)]
macro_rules! noop {
    () => {
        noop_helper!{}
    };
}

#[doc(hidden)]
#[macro_export]
macro_rules! noop_helper {
    () => {};
}

pub fn call() {
    noop!{}
}

error[E0433]: failed to resolve. Maybe a missing `extern crate noop_helper;`?
  --> src/lib.rs:6:9
   |
6  |         noop_helper!{}
   |         ^^^^^^^^^^^ Maybe a missing `extern crate noop_helper;`?
...
17 |     noop!{}
   |     ------- in this macro invocation

dtolnay · 2018-06-11T17:44:16Z

Ah, it appears the problem is not with this PR. The same thing happens invoking a macro through $crate just with use_extern_macros.

#![feature(use_extern_macros)]

#[macro_export]

dtolnay · 2018-06-11T17:48:08Z

I guess this is a consequence of #35896 (comment).

macro_rules! macros declared within the same crate still use the legacy visibility rules, and cannot be imported using use statements and path syntax

Seems easy to work around in any case, and uncommon anyway.

petrochenkov · 2018-06-11T18:27:10Z

Yes, $crate::foo!() where foo is local macro_rules! doesn't work if called in the same crate, this is the primary drawback of both this PR and explicitly writing $crate::foo!().

With duplicate macro_exports prohibited this should be fixable if $crate::foo!() is defined in the same way as it's visible from other crates, i.e. referring to the corresponding unique macro_exported macro and not to one of the macros named foo and defined in the root module.

macro_rules! foo { () => () } // (1)

mod m {
    // maybe somewhere in deeply nested modules
    #[macro_export] macro_rules! foo { () => () } (2)
}

macro_rules! foo { () => () } // (3), shadows (1) for the rest of the module

$crate::foo!(); // refers to (2), like from other crates, not to (1) or (3)

This doesn't seem urgent and blocking use_extern_macros though, because it's mostly about library's implementation conveniences and not about public interface.

dtolnay · 2018-06-11T18:36:43Z

Once "`macro_helper_hack` in `macro_export` is experimental" no longer happens (or if the merge is timed to never end up feature gated in a stable release), this resolves my concern about stabilizing use_extern_macros. 👍

petrochenkov · 2018-06-16T19:53:14Z

Updated.

Feature gate is removed.
macro_helper_hack is renamed into local_inner_macros

Bikeshedding about the attribute name is welcome.
local_inner_macros seemed like a reasonable name to me, but perhaps we should keep macro_helper_hack instead? :)
Any other suggestions?

joshtriplett · 2018-06-16T20:43:15Z

👍 for local_inner_macros, and for not bikeshedding this further given that this only exists for crates that need to support older rustc versions. Newer crates can and should use $crate:: explicitly.

nikomatsakis · 2018-06-18T17:34:55Z

@petrochenkov sorry for being slow to provide feedback. Mozilla All Hands was all consuming. I'll take a look and also skim the comments, but before that I wanted to say thanks for trying this out!

nikomatsakis · 2018-06-18T17:39:04Z

Well, I'm happy that @dtolnay is happy. It seems like it'd be good to get feedback from @nrc, who was one of the people pushing against "mixing the systems".

Let's notify people formally, there's a number of other things that should ideally get into 1.29 and are blocked on this PR.
Also marking as nominated to increase visibility.

@rfcbot fcp merge

This PR implements a solution for the macro helper issue described by dtolnay in #35896 (comment).

Macros exported from libraries can be marked with #[macro_export(local_inner_macros)] and this annotation changes how nested macros in them are resolved.

If we have a fn-like macro call ident!(...) and ident comes from a macro_rules! macro marked with #[macro_export(local_inner_macros)] then it's replaced with $crate::ident!(...) and resolved as such ($crate gets the same context as ident).

petrochenkov · 2018-06-20T08:11:29Z

cramertj · 2018-06-20T17:26:17Z

@petrochenkov This issue is tagged T-lang, so only lang team members can start FCP. I'll do it for you.

@rfcbot fcp merge

rfcbot · 2018-06-20T17:26:18Z

Team member @cramertj has proposed to merge this. The next step is review by the rest of the tagged teams:

Is there a writeup on the migration strategy for macro heavy crates, and how we can test with recent nightlies anywhere?

joshtriplett · 2018-08-06T20:32:04Z

@sgrif I don't know of a writeup to point to. The rough summary:

If your crate doesn't need compatibility with old stable versions of Rust, then when calling any macro from within a macro, use the $crate:: prefix.
If your crate needs compatibility with old stable versions of Rust, then add the #[macro_export(local_inner_macros)] attribute to your macros, which will automatically act as though all inner macro calls have a $crate:: prefix.
If you have macros that both call helper macros and call macros you expect the caller to define, then you either need to use $crate:: selectively on the helper macro calls, use #[macro_export(local_inner_macros)] but have helper macros that only call the caller-defined macros and don't use #[macro_export(local_inner_macros)] on those, or tell people they can't use use on your macros without also importing all your helper macros.

petrochenkov · 2018-08-06T20:51:42Z

If you have macros that both call helper macros and call macros you expect the caller to define, then you either need to use $crate:: selectively on the helper macro calls or tell people they can't use use on your macros without also importing all your helper macros.

Or use #[macro_export(local_inner_macros)] and one more level of indirection for the caller-defined parts.

joshtriplett · 2018-08-06T20:57:52Z

@petrochenkov Thanks, I've edited my comment to take that possibility into account.

sgrif · 2018-08-07T00:44:22Z

Do macros which take other macros as callbacks need this as well?
