am_insert: Insert a value into an Automerge list

In automerge: R Bindings for 'Automerge' 'CRDT' Library

Insert a value into an Automerge list

Description

This is an alias for am_put() with insert semantics for lists. For lists, am_put() with a numeric index replaces the element at that index, while am_insert() shifts elements to make room.

Usage

am_insert(doc, obj, pos, value)

Arguments

doc	An Automerge document
obj	An Automerge object ID (must be a list)
pos	Numeric index (1-based, like R vectors) where to insert, or "end" to append
value	The value to insert

Value

The document doc (invisibly)

Examples

doc <- am_create()

# Create a list and get it
am_put(doc, AM_ROOT, "items", AM_OBJ_TYPE_LIST)
items <- am_get(doc, AM_ROOT, "items")

# Insert items
am_insert(doc, items, "end", "first")
am_insert(doc, items, "end", "second")

am_close(doc)
