All notable changes to this project are documented here. The format follows Keep a Changelog, and the project follows semantic versioning.

Only the Tuplex module is public API. Tuplex.Telemetry documents the event vocabulary and is stable in the same sense. Tuplex.Store and Tuplex.Template are published for reference but are not covered by semantic versioning; everything else is internal.

0.1.0 — 2026-08-26

First release. A Linda tuple space for the BEAM, single-node.

Added

  • out/1, in/2, rd/2, inp/2, rdp/1, rd_all/1 — the Linda operations, with take/2 as an alias for in/2 for callers who would rather not qualify the operator name.
  • Leases. in/2 and inp/2 take lease: :monitor or lease: {:monitor, :ack}, which hold a tuple against the consuming process rather than removing it, so that a consumer that dies without finishing returns the tuple to the space instead of destroying it. This is the departure from classical Linda.
  • ack/1 to release a {:monitor, :ack} lease.
  • watch/2 and unwatch/1 — standing, non-consuming subscriptions to :out, :in and :requeue events, surviving shard restarts. Lossy under backpressure by design.
  • eval/1 — compute a tuple's contents in a fresh process. No failure channel, by design.
  • tags/0 — the live shard tags, for explicit whole-space sweeps.
  • Telemetry across the surface, with spans on in/2 and rd/2 and a periodic [:tuplex, :shard, :stats] per shard. See Tuplex.Telemetry.

Notes

  • Requires Elixir ~> 1.19 and OTP 28.
  • Everything is in memory. A node restart is an empty space; there is no persistence.
  • inp/2's exactness is shard-local — it rests on one process per tag serialising its own destructive reads, and would not survive unchanged into a distributed version.
  • :_ can be stored but never selected specifically, since :_ in a template is the wildcard. Documented as a limitation rather than rejected, because rejecting it correctly would mean a deep term walk on every write. See Tuplex.out/1.
