I noticed a workaround; consider the following script:
# -*- coding: utf-8 -*- from __future__ import print_function # Python2 vestige! # see https://community.notepad-plus-plus.org/topic/26799 "Two buffer-activated notifications instead of just one" from Npp import notepad, NOTIFICATION last_known_doc_index_by_view = [ notepad.getCurrentDocIndex(0), notepad.getCurrentDocIndex(1) ] def find_docindex_from_buffer_id_via_enumeration(test_buffer_id, must_be_in_this_view): for (pathname, buffer_id, index, view) in notepad.getFiles(): if view != must_be_in_this_view: continue # needed to find the right doc in case of cloned doc if buffer_id == test_buffer_id: return index return -1 # never happens def bufferactivated_callback(args): cfn = notepad.getCurrentFilename().rsplit('\\', 1)[-1] # only the filename, no directory print('BUFFERACTIVATED:', cfn, 'args=', args) current_view = notepad.getCurrentView() current_doc_index = notepad.getCurrentDocIndex(current_view) curr_doc_index_via_enumerating = find_docindex_from_buffer_id_via_enumeration(args['bufferID'], current_view) if current_doc_index != curr_doc_index_via_enumerating: print(' NOT A NEEDED ACTIVATION NOTIFICATION!!!!!!') return print(' HANDLING A REAL ACTIVATION NOTIFICATION!') if last_known_doc_index_by_view[current_view] == current_doc_index: print(' note: THIS DOC WAS ALREADY ACTIVE IN THE ITS VIEW -- so was an activation notify really necessary?') else: last_known_doc_index_by_view[current_view] = current_doc_index notepad.callback(bufferactivated_callback, [NOTIFICATION.BUFFERACTIVATED])This workaround works because the “index” reported with the bogus notification is also bogus, and the correct index can be found by looking through the entire tab list for the right buffer id.
A subtle point of the script is that it can also detect when the active tab in the inactive view is activated by the user.
