• Add FromMeta impl for u128 and i128 #243

v0.20.2 (May 25, 2023)

• Allow darling users to omit quotation marks for paths and idents #236

v0.20.0 (April 27, 2023)

• Bump syn to version 2, courtesy of @jonasbb #227

Breaking Changes

• Replace all occurrences of syn::NestedMeta with darling::ast::NestedMeta.

• Replacement for the deprecated AttributeArgs:

// Before

parse_macro_input!(args as AttributeArgs);

// After

match NestedMeta::parse_meta_list(args) {
    Ok(v) => v,
    Err(e) => { 
      return TokenStream::from(Error::from(e).write_errors()); 
    }
};

• In GenericParamExt, LifetimeDef is now LifetimeParam.
• In GenericParamExt, as_lifetime_def is renamed to as_lifetime_param.
• Flag and SpannedValue no longer implement syn::spanned::Spanned.
• The MSRV (minimum supported Rust version) is now 1.56, because of syn.

Deprecation Warnings

In previous versions of darling, arbitrary expressions were passed in attributes by wrapping them in quotation marks. v0.20.0 preserves this behavior for syn::Expr, but as a result a field expecting a syn::Expr cannot accept a string literal - it will incorrectly attempt to parse the contents. If this is an issue for you, please add a comment to #229.

v0.14.4 (March 9, 2023)

• Add support for child diagnostics when diagnostics feature enabled #224

v0.14.3 (February 3, 2023)

• Re-export syn from darling to avoid requiring that consuming crates have a syn dependency.
• Change <SpannedValue<T> as FromMeta> impl to more precisely capture the value span, as opposed to the span of the entire item.
• Add darling::util::{AsShape, Shape, ShapeSet} to improve "shape" validation for structs and variants. #222

v0.14.2 (October 26, 2022)

• Derived impls of FromMeta will now error on literals, rather than silently ignoring them. #193
• Don't include property paths in compile errors when spans are available. #203

v0.14.1 (April 28, 2022)

• Fix a bug where using a trait that accepts #[darling(attributes(...))] without specifying any attributes would emit code that did not compile. #183
• Impl Clone for darling::Error #184
• Impl From<darling::Error> for syn::Error #184
• Add Error::span and Error::explicit_span methods #184

v0.14.0 (April 13, 2022)

• BREAKING CHANGE: Remove many trait impls from util::Flag. This type had a number of deref and operator impls that made it usable as sort-of-a-boolean. Real-world usage showed this type is more useful if it's able to carry a span for good errors, and that most of those impls were unnecessary. #179
• Remove need for #[darling(default)] on Option<T> and Flag fields #161
• Improve validation of enum shapes #178
• Bump proc-macro2 dependency to 1.0.37 #180

v0.12.2 (February 23, 2021)

• Impl FromMeta for HashMap<Ident, V> and HashMap<Path, V>

v0.12.1 (February 22, 2021)

• Add darling::ast::Data::try_empty_from to avoid panics when trying to read a union body #123

v0.12.0 (January 5, 2021)

• POSSIBLY BREAKING: Derived impls of FromDeriveInput, FromField, FromVariant, and FromTypeParam will now error when encountering an attribute darling has been asked to parse that isn't a supported shape. Any crates using darling that relied on those attributes being silently ignored could see new errors reported in their dependent crates. #113
• Impl syn::spanned::Spanned for darling::util::SpannedValue #113
• Add darling::util::parse_attribute_to_meta_list to provide useful errors during attribute parsing #113
• Add impl From<syn::Error> for Error to losslessly propagate syn errors #116

• Attach spans to errors for types with provided bespoke implementations
• Deprecate set_span from 0.8.2, as spans should never be broadened after being initially set

v0.8.2 (January 17, 2019)

• Add spans to errors to make quality warnings and errors easy in darling. This is blocked on diagnostics stabilizing.
• Add darling::util::SpannedValue so proc-macro authors can remember position information alongside parsed values.
