v0.4.0 (2023-03-20)

BREAKING CHANGE

• The macro will generate types for transparent variants/structs and this can be disabled by #[thisctx(skip)] attribute.
• The Context suffix will not be appended to types generated from an enum by default. This can be enabled by add #[thisctx(suffix)] to the enum.
• Use the attribute #[thisctx(skip)] instead of #[thisctx(context(false))] to skip a varaint.

Feat

• derive: add shortcuts for common attributes
• derive: use snake case of input as module name by default
• derive: add attribute no_suffix as a shortcut to suffix(false)
• derive: add no_unit, no_generic and no_skip attributes

Fix

• derive: check duplicated options
• derive: ensure the order when inheriting options

Refactor

• derive: remove unused code
• packages: move packages/* to project root
• derive: use a generic way to parse options
• derive: dont skip transparent variants by default
• derive: disable #[thisctx(suffix)] on an enum
• derive: rename #[thisctx(context)] to #[thisctx(skip)]

v0.3.0 (2023-03-11)

Feat

• derive: allow use #[thisctx(pub(...))] to change visibility
• lib: use into() to construct the source type of a context
• lib: use NoneSource instead of ()

Fix

• derive: only impl From<Context> for an error when source is not specified

Refactor

• lib: traits require Sized bound
• derive: simplify implementation details

v0.2.0 (2023-01-09)

Feat

• derive: change MSRV to v1.33
• derive: support #[thisctx(attr = "...")] syntax
• minimal suppoted rust version v1.34
• derive: use #[thisctx(module)] to generate context types into a single module
• lib: add IntoError::{build, fail}
• derive: convert context types into errors when associated source types implement Default
• derive: add attributes #[thisctx(context)] and #[thisctx(generic)]
• lib: support #![no_std]
• derive: support generics (#7)
• derive: associate contexts with a remote error (#6)
• derive: support add extra attributes to generated types (#5)
• derive: auto generate unit structs for empty contexts (#4)
• derive: generate extra traits and methods (#3)
• derive: add attribute #[thisctx(suffix)] (#2)
• derive: add attribute #[thisctx(visibility)] (#1)
• impl: use derive macro instead
• macro: implement fail() for @context
• macro: implement build() for @context
• macro: implement From<@source> for error enum
• macro: do not generate context without @context
• macro: no generic for unit context struct

Fix

• derive: allow #[error] attribute
• derive: generate conversion generics based on field names
• derive: don't generate into_error method
• derive: inherit visibility for generated fields

Refactor

• derive: use more new type patterns
• macro: use IntoError::into_error() in @context::build()
• macro: reduce redundant code
• macro: rename some items
• macro: make Parse of Context separate

v0.1.0 (2021-06-18)

BREAKING CHANGE

• The tuple variant will be resolved in a similar way to the Sturct Variant, which means you have to explicitly provide @source and @context.

Feat

• macro: support add attributes to source and context fields
• ext: add context_with()
• macro: support generic context
• macro: support empty tuple variant
• support visibility control
• support tuple variant
• move thisctx::ext::{IntoError,NoneError} to public
• implement converting from context without source for error enum
• implement IntoError for context struts, add ResultExt and OptionExt
• support tuple struct context
• use proc_macro instead of macro_rules
• support unit and struct enum variants

Refactor

• macro: eliminate redundant code
• macro: eliminate redundant code
• rewrite thisctx_impl::expand
• rename local variables, remove redundant code
