RPC is the typical way to control Nvim programmatically. Nvim implements the
MessagePack-RPC protocol:

+Extended marks *api-extended-marks*
+
+Extended marks (extmarks) represent buffer annotations that track text changes
+in the buffer. They could be used to represent cursors, folds, misspelled
+words, and anything else that needs to track a logical location in the buffer
+over time.
+
+Example:
+
+We will set an extmark at the first row and third column. |api-indexing| is
+zero-indexed, so we use row=0 and column=2. Passing id=0 creates a new mark
+and returns the id: >
+
+ let g:mark_ns = nvim_create_namespace('myplugin')
+ let g:mark_id = nvim_buf_set_extmark(0, g:mark_ns, 0, 0, 2, {})
+
+We can get a mark by its id: >
+
+ echo nvim_buf_get_extmark_by_id(0, g:mark_ns, g:mark_id)
+ => [0, 2]
+
+We can get all marks in a buffer for our namespace (or by a range): >
+
+ echo nvim_buf_get_extmarks(0, g:mark_ns, 0, -1, {})
+ => [[1, 0, 2]]
+
+Deleting all text surrounding an extmark does not remove the extmark. To
+remove an extmark use |nvim_buf_del_extmark()|.
+
+Namespaces allow your plugin to manage only its own extmarks, ignoring those
+created by another plugin.
+
+Extmark positions changed by an edit will be restored on undo/redo. Creating
+and deleting extmarks is not a buffer change, thus new undo states are not
+created for extmark changes.
