Unreleased

0.1.0 - 2026-09-07

Initial release.

Added

  • Mutare.Phoenix.LiveView.Navigation (:lv_nav) — swaps push_navigate ↔ push_patch at the arity-2 form both share.
  • Mutare.Phoenix.LiveView.Reply (:lv_reply) — drops a callback's optional trailing tuple element ({:reply, payload, socket} → {:noreply, socket}, {:ok, socket, opts} → {:ok, socket}), gated on the enclosing module's Phoenix.LiveView / Phoenix.LiveComponent behaviour.
  • Mutare.Phoenix.LiveView.Stream (:lv_stream) — swaps stream_insert ↔ stream_delete at the arity-3 form both share (swap); swaps at: 0 ↔ at: -1 on stream_insert/4 (at — prepend vs append; the covering rewrite supersedes core's integer leaves there via overlap pruning); drops the limit: entry of stream/4 / stream_insert/4 (limit). A reset: true drop is deliberately absent — it is core's boolean flip in disguise.
  • Mutare.Phoenix.LiveView.Event (:lv_event) — removes push_event/3,4, collapsing to the socket (or Function.identity() when piped).
  • Mutare.Phoenix.LiveView.SendUpdate (:lv_send_update) — removes send_update/2,3 / send_update_after/3,4, collapsing to a faithful stand-in (:ok / a fresh make_ref() for _after's timer ref) (remove); and turns send_update_after/3,4 into an immediate send_update that still yields a ref (immediate — deletes the delay). The delay argument is a marked :timeout position, so core's literal families skip it.
  • Mutare.Phoenix.LiveView.Hook (:lv_hook) — removes attach_hook/4 (attach — the hook never runs) and detach_hook/3 (detach — the hook keeps running), collapsing to the socket. Hook name and stage atoms are routed :raw, so no core family mutates them.
  • Registers the LiveView compile-time DSL (live/live_session, on_mount, attr/slot/embed_templates) as :skip through Mutare.CallRouting, so declarations that run once as mutant 0 are left unmutated.
  • Mutare.Phoenix.LiveView.all/0 for splicing the six families into a :mutators list, composing with Mutare.Phoenix.all/0.
