am_insert: 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)

Value

The document doc (invisibly)

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

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")
