API Reference tamale v#0.1.0

Present some golbal types.

The anchor algebra.

Coordinate anchor: an interval in some coordinate system (:tick, :seconds, {:frames, hz}, ...).

Identity anchor.

Compound anchor: ref travels by identity (Ordinal rules), then the absolute interval is re-derived from the element's current span at use time — Tamale.Anchor.project/3, with element spans supplied by the Caller.

The single kernel-mandated channel-adapter callback.

Exact rational coordinates — the kernel's only number.

Canonical digests — the portable replacement for BEAM-specific term_to_binary hashing. Spec: docs/spec/canonical-digest.md.

Edit operations — the kernel's first-class edit intent.

Delete id. Terminal for anchors referencing it.

Insert id after after_id (:head inserts at the front).

Merge adjacent ids into into, which must be hd(ids).

Move id to right after after_id (:head = front).

Re-time id from old_span to new_span ({start, stop} in the space's native coordinate). Identity and order are untouched; the spans exist so the adapter layer can build warps for Anchor.Metric.

Split id into children; hd(children) must equal id.

Semantic survival: a user edit is (base_digest, payload).

A versioned identity space: an ordered set of element ids, an append-only op log, and nothing else.

Anchor transport along the op log — the whole of rebase.

A monotone partial map between coordinate systems — the transport medium for Tamale.Anchor.Metric.
