Doc comments to attribute conversion without syntactic sugar

[l0kod]

Like the doc said and then refute, /// Foo turns into #[doc="/// Foo"] which is a bug. It should turns into #[doc="Foo"] (without the ///). Same apply for /** … */.

This is an issue for macro using the meta matcher (cf. #13067) to insert doc into generated code.

Another interesting symptom is that it doesn't insert any whitespace. Everything gets run together on one line making it look like this in the docs.

/// Sets the global velocity damping. /// /// Defaults to 1.0 (no damping). /// /// This value is the fraction of velocity a body should have after 1 /// second. A value of 0.9 would mean that each second, a body would have /// 90% of the velocity it had the previous second.

I believe this desugaring is still the case, although I'm not sure I understand why this affects the use of meta (this issue is a bit old, but maybe you remember, @l0kod?).

@steveklabnik: Should this old issue receive additional tags and/or be closed?

yup, without more info, gonna consider this one closed. @l0kod if you still have something here, please just open a new issue with the current context, thanks!
