automerge (version 0.2.0)

am_get_heads: Get the current heads of a document

Description

Returns the current "heads" of the document - the hashes of the most recent changes. These identify the current state of the document and can be used for history operations.

Usage

am_get_heads(doc)

Value

A list of raw vectors, each containing a change hash. Usually there is only one head, but after concurrent edits there may be multiple heads until they are merged by a subsequent commit.

Arguments

doc

An Automerge document

Examples

doc <- am_create()
am_put(doc, AM_ROOT, "x", 1)
am_commit(doc)

heads <- am_get_heads(doc)
cat("Document has", length(heads), "head(s)\n")
