This changes vim motions to be relative to fold lines, not display
lines, to match the behaviour of vim.
This is necessary for relative line numbers to make sense (as the most
important thing is you can do `3j` to get th e line that is numbered 3).
Release Notes:
- vim: Fix handling of motions when `soft_wrap` is enabled in zed. Like
in vim `j,k,up,down,$,^,0,home,end` will all now navigate in file
coordinates not display coordinates.
- vim: Add `g {j,k,up,down,$,^,0,home,end}` to navigate in display
coordinates.
- vim: Add `z o` and `z c` to open and close folds.
- vim: Add `z f` in visual mode to fold selection.
Note: this may be a jarring change if you're grown used to the current
behaviour of `j` and `k`. You can make the issue less acute by setting
`"soft_wrap":"none"` in your settings; or you can manually copy the
bindings for `g j` to the binding for `j` (etc.) in your keymap.json to
preserve the existing behaviour.
See Linear description for the full explanation of the issue. This PR is
mostly a mechanical change, except for the one case where we do pass in
an explicit `next_id` instead of `model_id` in project.rs.
Release Notes:
- Fixed a bug where some results were not reported in project search in
presence of unnamed buffers.
Before this change up and down were in display co-ordinates, after this
change they are in fold coordinates (which matches the vim behaviour).
To make this work without causing usabliity problems, a bunch of extra
keyboard shortcuts now work:
- vim: `z {o,c}` to open,close a fold
- vim: `z f` to fold current visual selection
- vim: `g {j,k,up,down}` to move up/down a display line
- vim: `g {0,^,$,home,end}` to get to start/end of a display line
Fixes: zed-industries/community#1562
These primarily happen when first entering visual mode, but can also
be created with objects like `vi{`.
Along the way fix the way ranges like `vi{` are selected to be more
similar to nvim.
