Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

  • substitute! and substitute_item allow the use of global substitutions without duplication. See #49.

Changed

  • [BREAKING] Increased base MSRV to 1.65.
  • [BREAKING] duplicate! and duplicate_item no longer allow using exclusively global substitutions.
  • Edition increased to 2021.
  • Replaced proc-macro-error dependency with proc-macro2-diagnostics for printing nice error messages and hints. See #61.
  • Updated heck dependency to version 0.5.

[1.0.0] - 2023-03-10

Changed

  • Overhauled the pretty_errors feature to more consistently provide useful hints and code highlights. See #19.

Fixed

  • duplicate now also substitutes the invocations of nested duplicate's. See #48.
  • Forgetting to enclose subtitution parameters in brackets now reports sensible error. See #30.
  • Short syntax no longer accepts providing no substitution groups after the identifier list. See #29.
  • Fixed several issues where code was accepted which shouldn't have been.

[0.4.1] - 2022-07-17

Fixed

  • Fixed an issue where duplicate's edition would leak into the user's code. See #47.

[0.4.0] - 2022-02-20

Added

  • Nested invocations can now be used everywhere.

Changed

  • [BREAKING] Renamed duplicate::duplicate to duplicate::duplicate_item. See #40.
  • [BREAKING] Renamed duplicate::duplicate_inline to duplicate::duplicate. See #40.
  • [BREAKING] Nested invocation now uses duplicate!{[<invocation>] <body>} syntax instead of #[<invocation>][<body>]. See #28.
  • [BREAKING] Increased base MSRV to 1.42. See #45
  • [BREAKING] Relaxed MSRV policy. Only the minimal versions of direct and transitive dependencies are guaranteed to work for the MSRV. See #44
  • No longer pinning dependencies following new MSRV policy.
  • Updated heck dependency to version 0.4.

[0.3.0] - 2021-06-08

Added

  • Global Substitution: Allows substitutions that are applied to all duplicates equally. See #23.

Changed

  • [BREAKING] Limited which group delimiters are allowed in various syntactic positions. The specific delimiters required now follow the use of delimiters in previous documentation examples. See #25.
  • Substituted the convert_case dependency for heck. See #22.

Fixed

  • Now also substitutes code inside substitution arguments. See #24.
  • Module_disambiguation: Now only substitutes the module name and not any matching identifier in the body of the module. See #27.

[0.2.9] - 2020-09-28

Added

  • New Minimum Supported Rust Version (MSRV) Policy. Briefly, MSRV is 1.34 but may be increased by enabling features. See #18.
  • The crate's readme now contains section on MSRV policy.
  • Parameterized substitution is now also available for the verbose syntax. See #8.

[0.2.8] - 2020-09-24

[0.2.7] - 2020-08-10

Added

  • duplicate_inline: Function-like procedural macro version of duplicate. Has the same functionality, but can be used in other contexts and can duplicate any number of items. See also #6.

Changed

  • Updated proc_macro_error dependency to version 1.0.4.

[0.2.6] - 2020-07-13

Added

  • New feature named pretty_errors (enabled by default). When enabled, errors are more detailed and helpful.
  • New feature named module_disambiguation (enabled by default). When enabled, automatically uses a suitable substitution identifier to disambiguate the name of a module being duplicated. See the documentation for more details. See also #7.

Changed

  • Errors are now less detailed and helpful unless the pretty_errors feature is enabled.
  • The dependence on the proc_macro_error crate is now optional and used by the pretty_errors feature.

[0.2.5] - 2020-06-29

Fixed

  • Fixed a build issue when using version 1.0.3 of proc_macro_error. See #11.

Changed

  • The proc_macro_error dependency is fixed to version 1.0.3 to avoid potential breaking changes with future updates to that crate.

[0.2.4] - 2020-06-23

Fixed

  • Fixed issue with the short syntax where substitutions that included any bracket type would be expanded wrong. See #9.

[0.2.3] - 2020-06-21 [YANKED]

Added

  • Short syntax now supports parameterized substitution. This allows identifiers to take arguments that can be used to customize the substitution for each use. See #5.

[0.2.2] - 2020-05-17

Added

  • Short syntax now supports nested macro invocations. Can only be used after the initial list of substitution identifiers. See #2.

Changed

  • Updated documentation. The short syntax is now used for the primary examples.
  • Crate readme license section no longer includes paragraph on the licensing of contibutions.

Fixed

  • Fixed an issue where #[duplicate(..)] would throw an error if it was generated by a macro expansion. It would fail if a substitution identifier originated from a macro variable. This is caused by the variable's expansion sometimes being wrapped in a group with no delimiters, which duplicate couldn't handle.

[0.2.1] - 2020-04-26

Changed

  • Updated crate readme to new short syntax.

[0.2.0] - 2020-04-26

Added

Changed

  • New short syntax with row-based substitution groups instead of the old column-based syntax. See github issue.

[0.1.5] - 2020-04-12

Changed

  • Crate readme format titles are now bigger than changelog entries.

[0.1.4] - 2020-04-12

Added

  • Crate readme now includes list of changes when published to crates.io.

[0.1.3] - 2020-04-12

[0.1.2] - 2020-04-9

Added

  • duplicate attribute macro for code duplication and substitution.
  • Short invocation syntax for duplicate.
  • Verbose invocation syntax for duplicate.
