Unreleased

Removals

  • walk, prewalk, and postwalk have been removed. Use map-model and map-hyseq instead.

Breaking Changes

  • recur is now a real object that must be imported from Hyrule when using loop.
  • macroexpand-all now uses the same parameters as hy.macroexpand.
  • lif now treats False as false.

New Features

  • New macro pun.
  • New macro map-hyseq.
  • loop allows more kinds of parameters.
  • flatten, given a non-collection, returns it as a singleton list, instead of raising an error.

Bug Fixes

  • map-model now calls as-model only once (before its own recursion), and it does so unconditionally.
  • loop now works when nested.
  • macroexpand-all no longer crashes on stub macros.
  • macroexpand-all now recognizes macro names properly.
  • lif now works when renamed, or when invoked with hy.R.

0.7.0 (released 2024-09-22; uses Hy ≥ 1)

New Features

  • New macros meth and ameth.

Bug Fixes

  • match-fn-params now raises an error for syntactically invalid parameter lists.

0.6.0 (released 2024-05-20; uses Hy 0.29.*)

Removals

  • defmacro/g! has been removed. Use defmacro! instead.

Other Breaking Changes

  • cut on a Sequence now returns another Sequence, not a generator.
  • assoc is now a function rather than a macro. Its effect is unchanged.

New Features

  • The Sequence constructor now accepts an arbitrary iterable.
  • New macro defmacro-kwargs.
  • New macro parse-fn-params.
  • New macro some->.
  • New function import-path.
  • New function sign.
  • New function thru.

Bug Fixes

  • defmacro! now properly handles explicit return statements within its macro definition.
  • Various Sequence bugs have been fixed.
  • assoc no longer requires a second and third argument.

0.5.0 (released 2024-01-05; uses Hy 0.28.*)

No user-visible changes beyond compatibility with new Hy versions.

0.4.0 (released 2023-07-06; uses Hy 0.27.*)

New Features

  • do-n and list-n now allow the count to be Inf.
  • New reader macro / that wraps hy.M for easy imports in macros.

Bug Fixes

  • seq and defseq no longer crash if Sequence is not imported.
  • ->, ->>, and doto now properly handle bare symbols with leading dot.

0.3.0 (released 2023-02-08; uses Hy 0.26.*)

New Features

  • New macros ap-when, ap-with.

0.2.1 (released 2022-11-08; uses Hy 0.24.0 or 0.25.*)

Changed setup.py to declare compatibility with the new Hy release.

0.2 (released 2022-06-23; uses Hy 0.24.0)

Removals

  • ifp has been removed. Use branch instead.

Other Breaking Changes

  • The reader macro (formerly tag macro) : is now named s.

New Features

  • New macro block.
  • New macros branch, ebranch, case, and ecase.
  • The macros of hyrule.anaphoric are now much smarter in deciding what instances of the symbol it to replace, so you can now quote or locally rebind it without issues.

Bug Fixes

  • Destructuring macros now consistently return None in case of failing to match a certain pattern, instead of sometimes returning None and sometimes raising an exception.
  • #% now parses %i names from dotted symbols.
  • The Hy code is now precompiled during installation.

0.1 (released 2022-01-09; uses Hy 1.0a4)

This is the first release of Hyrule per se. The one change below is described relative to the ancestors of Hyrule in Hy 1.0a3.

Breaking Changes

  • coll? now returns False for bytes objects.
