Ref: #9342
Adds the option to have a single global statusline for the current window at the bottom of the screen instead of a statusline at the bottom of every window. Enabled by setting `laststatus = 3`.
Due to the fact that statuslines at the bottom of windows are removed when global statusline is enabled, horizontal separators are used instead to separate horizontal splits. The horizontal separator character is configurable through the`horiz` item in `'fillchars'`. Separator connector characters are also used to connect the horizontal and vertical separators together, which are also configurable through the `horizup`, `horizdown`, `vertleft`, `vertright` and `verthoriz` items in `fillchars`.
The window separators are highlighted using the `WinSeparator` highlight group, which supersedes `VertSplit` and is linked to `VertSplit` by default in order to maintain backwards compatibility.
Don't add sign extmarks to state->active. Instead when drawing signs,
perform a full line scan for sign marks. This allows decor_redraw_line
to be moved back inside the `!number_only` block in screen.c, which
prevents decor scans when redrawing the number column when
'relativenumber' is set.
Fixes: #17638
Add the following options to extmarks:
- sign_text
- sign_hl_group
- number_hl_group
- line_hl_group
- cursorline_hl_group
Note: ranges are unsupported and decorations are only applied to
start_row
This commit finishes support for colored and styled underlines adding
`CSI 4 : [2,4,5] m` support providing double, dashed, and dotted
underlines
Fixes#17362.
Add tests for:
- Cursor position restored after :map expr
- Cursor position restored after :imap expr
- Error in :cmap expr handled correctly
Cherry-picked from #12837
When `signcolumn=number` but no sign on a given line has any text,
display the line's line number instead of the (empty) sign text in the
line number column.
Nvim already resizes grid to the required width, so there is no need to
truncate the text in pum_redraw(). What's more, truncation is currently
done incorrectly because Vim patch 8.2.1995 was ported incorrectly.
This nearly reverts the truncation part of Vim patch 8.2.1995, but not
the part that reduces unnecessary calls to pum_redraw(). The original PR
https://github.com/vim/vim/pull/7306 didn't explain much about which
part of it actually reduces redraws.
