patch 9.0.2074: Completion menu may be wrong Commit: https://github.com/vim/vim/commit/daef8c74375141974d61b85199b383017644978c Author: Christian Brabandt <cb@256bit.org> Date: Fri Oct 27 19:16:26 2023 +0200 patch 9.0.2074: Completion menu may be wrong Problem: Completion menu may be wrong Solution: Check for the original direction of the completion menu, add more tests, make it work with 'noselect' completion: move in right direction when filling completion_info() When moving through the insert completion menu and switching directions, we need to make sure we start at the correct position in the list and move correctly forward/backwards through it, so that we do not skip entries and the selected item points to the correct entry in the list of completion entries generated by the completion_info() function. The general case is this: 1) CTRL-X CTRL-N, we will traverse the list starting from compl_first_match and then go forwards (using the cp->next pointer) through the list (skipping the very first entry, which has the CP_ORIGINAL_TEXT flag set (since that is the empty/non-selected entry 2) CTRL-X CTRL-P, we will traverse the list starting from compl_first_match (which now points to the last entry). The previous entry will have the CP_ORIGINAL_TEXT flag set, so we need to start traversing the list from the second prev pointer. There are in fact 2 special cases after starting the completion menu with CTRL-X: 3) CTRL-N and then going backwards by pressing CTRL-P again. compl_first_match will point to the same entry as in step 1 above, but since compl_dir_foward() has been switched by pressing CTRL-P to backwards we need to pretend to be in still in case 1 and still traverse the list in forward direction using the cp_next pointer 4) CTRL-P and then going forwards by pressing CTRL-N again. compl_first_match will point to the same entry as in step 2 above, but since compl_dir_foward() has been switched by pressing CTRL-N to forwards we need to pretend to be in still in case 2 and still traverse the list in backward direction using the cp_prev pointer For the 'noselect' case however, this is slightly different again. When going backwards, we only need to go one cp_prev pointer back. And resting of the direction works again slightly different. So we need to take the noselect option into account when deciding in which direction to iterate through the list of matches. related: #13402 related: #12971 closes: #13408 Signed-off-by: Christian Brabandt <cb@256bit.org>
