* edit.c: Ensure undo sync when emulating <Esc>x #11706Matthew Malcomson2020-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After PR #8226 an unmapped META key in insert mode behaves like ESC-<key> (:help i_META). The behaviour does not fully match, since if <Esc>-<key> is pressed manually then since it were pressed manually `gotchars` would be called on the second <key> after insert-mode had already been left. This would mean that `may_sync_undo` (called from `gotchars`) would call `u_sync(FALSE)` on the second key (since we would be in normal mode). This overall means that <Meta-[something]> behaves differently with respect to undo than <Esc>[something] when the [something] makes a change. As an example, under `nvim -u NONE`: ihello<M-.>u leaves the buffer empty, while ihello<Esc>.u leaves the buffer with one instance of `hello`. - Fix by calling u_sync() manually in the new clause under `normalchar:` in `insert_handle_key`. - Update test in tui_spec.lua that accidentally relied on the old behaviour.

* i_CTRL-O: fix :startinsert at end of line (#6963)d10n2017-07-08
| | | | | | | | | | | | | | | | | | | | | | The gchar_cursor() == NUL check is already done in ins_ctrl_o. ins_esc changes gchar_cursor() so this if block is probably never entered. Issue: Pressing CTRL-O in insert mode at the end of the line and typing :startinsert moves the cursor 1 column back, when I expect the cursor to remain at the end of the line This is a regression from Vim behavior. Since at least Vim version 7.0, Vim returns you to insert mode at the end of the line. 091e7d033cbf0f4da068292ce4ac934f1c3dd91e is the first bad neovim commit Steps to reproduce using `nvim -u NORC`: `aaaa<C-o>:startinsert<CR>` Fixes #6962

* edit.c: CTRL-SPC: Insert previously-inserted text. #6090Matthew Malcomson2017-02-28
Default Vim behavior of i_CTRL-<Space> is to insert the last-inserted text and exit insert mode. :help i_CTRL-@ Before this commit that did not happen because insert_handle_key() checks for NUL instead of checking for ' ' with a CTRL `mod_mask`. I'm leaving the check for NUL despite the fact that at the moment that key is never seen when using the terminal UI (not for C-Space, nor C-@). This is because I assume it's still allowed for other front-ends to pass NUL, but at the moment the terminal UI isn't.
