Nightly only, they're ignored on stable. +* Now `proc-macro-error` delegates to `proc_macro::Diagnostic` on nightly. + +## Breaking changes +* `MacroError` is now replaced by `Diagnostic`. Its API resembles `proc_macro::Diagnostic`. +* `Diagnostic` does not implement `From<&str/String>` so `Result<T, &str/String>::abort_or_exit()` + won't work anymore (nobody used it anyway). +* `macro_error!` macro is replaced with `diagnostic!`. + +## Improvements +* Now `proc-macro-error` renders notes exactly just like rustc does. +* We don't parse a body of a function annotated with `#[proc_macro_error]` anymore, + only looking at the signature. This should somewhat decrease expansion time for large functions. + +# v0.3.3 (2019-10-16) +* Now you can use any word instead of "help", undocumented. + +# v0.3.2 (2019-10-16) +* Introduced support for "help" messages, undocumented. + +# v0.3.0 (2019-10-8) + +## The crate has been completely rewritten from scratch! + +## Changes (most are breaking): +* Renamed macros: + * `span_error` => `abort` + * `call_site_error` => `abort_call_site` +* `filter_macro_errors` was replaced by `#[proc_macro_error]` attribute. +* `set_dummy` now takes `TokenStream` instead of `Option<TokenStream>` +* Support for multiple errors via `emit_error` and `emit_call_site_error` +* New `macro_error` macro for building errors in format=like style. +* `MacroError` API had been reconsidered. It also now implements `quote::ToTokens`. + +# v0.2.6 (2019-09-02) +* Introduce support for dummy implementations via `dummy::set_dummy` +* `multi::*` is now deprecated, will be completely rewritten in v0.3 + +# v0.2.0 (2019-08-15) + +## Breaking changes +* `trigger_error` replaced with `MacroError::trigger` and `filter_macro_error_panics` + is hidden from docs. + This is not quite a breaking change since users weren't supposed to use these functions directly anyway. +* All dependencies are updated to `v1.*`. + +## New features +* Ability to stack multiple errors via `multi::MultiMacroErrors` and emit them at once. + +## Improvements +* Now `MacroError` implements `std::fmt::Display` instead of `std::string::ToString`. +* `MacroError::span` inherent method. +* `From<MacroError> for proc_macro/proc_macro2::TokenStream` implementations. +* `AsRef/AsMut<String> for MacroError` implementations. + +# v0.1.x (2019-07-XX) + +## New features +* An easy way to report errors inside within a proc-macro via `span_error`, + `call_site_error` and `filter_macro_errors`. |
