Problem:
The DSR wait warning causes any test that involves Nvim TUI to become
flaky on Windows. Example:
FAILED test/functional/terminal/cursor_spec.lua @ 367: :terminal cursor can be positioned arbitrarily
test/functional/terminal\cursor_spec.lua:377: Row 1 did not match.
Expected:
|*^ |
|*~ |
|*~ |
|*~ |
|*~ |
|* |
|{5:-- TERMINAL --} |
Actual:
|* |
|* |
|*{2: }|
|*{103:defaults.lua: Did not detect DSR response from ter}|
|*{103:minal. This results in a slower startup time. }|
|*{UNEXPECTED foreground = tonumber('0x000006'):Press ENTER or type command to continue^ }|
|{5:-- TERMINAL --} |
Solution:
Don't show the DSR wait warning when running tests.
Problem: Unable to configure message targets based on message kind.
Solution: Add cfg.msg.targets mapping message kinds to "cmd/msg/pager".
Check the configured target when writing the message.
cfg.msg = { target = 'cmd', targets = { progress = 'msg', list_cmd = 'pager' } }
will for example use the 'msg' target for progress messages,
immediately open the pager for 'list_cmd' and use the cmdline
for all other message kinds.
Problem:
Descriptions of plugins often contain taglinks which are generally
concealed. This misaligns them by 2 characters with descriptions that
don't have a taglink in them.
Solution:
Don't count "bar" characters (`|`) for the description width.
Example:
Actual buffer content:
```
myplugin.txt |lsp| is cool
myplugin.txt this is a nice plugin
```
Rendered as:
```
myplugin.txt lsp is cool
myplugin.txt this is a nice plugin
```
Problem:
Automatic background detection sets the background option too late,
which loads colorschemes twice and causes problems when the user's
terminal background doesn't match the default (#32109, #36211, #36416).
Solution:
Use a DA1 query to determine whether the TTY supports OSC 11. Wait for
background detection and setting to complete before processing user
config.
Note: To preserve the existing behavior as much as possible, this triggers
OptionSet manually on VimEnter (since it won't trigger automatically if
we set bg during startup). However, I'm unsure if this behavior is
truly desired given that the documentation says OptionSet is triggered
"After setting an option (except during |startup|)."
Also fixes flickering issue #28667. To check for flickering:
nvim --clean --cmd "set termguicolors" --cmd "echo \"foo\"" --cmd "sleep 10"
On master, this gives me a black screen for 10 seconds, but on this
branch, the background is dark or light depending on the terminal
background (since the option is now set during startup rather than after
VimEnter).
Problem: Timer removing a message from the msg buffer does not remove
empty lines if window is closed (col([ui.wins.msg]) fails).
Solution: Use nvim_buf_get_text() to check if line is empty.
Problem: - Unintentionally inserting lines for a replaced multiline
message that also has multiple highlights.
- Scheduled check to see if the expanded cmdline window was
entered makes it difficult to keep track of what happens when
the key pressed to dismiss it results in a message.
- Reading the first line of an error message should be enough
notice for something going wrong.
- "search_cmd" messages should not be shown with 0 'cmdheight'.
- Unable to configure dynamically changed pager height.
- Enabling UI2 doesn't make sense with no UIs attached.
Solution: - Only insert a line for the first chunk after a newline.
- Use getmousepos() to check if the expanded cmdline was
clicked to enter the pager.
entering the pager to serve as a configuration interface.
- Don't expand the cmdline for error messages; user can press g<.
- Don't show "search_cmd" messages with 'cmdheight' set to 0.
- Change 'eventignorewin' to ensure WinEnter is fired when
- Have enable() return early when no UIs are attached.
Problem: Implicitly setting message target when 'cmdheight' changes.
Solution: Just use the user configured target. Support "cmd" target
with 'cmdheight' set to 0.
Problem: Paging keys being consumed without obvious indicator
in the dialog window can be surprising.
Solution: Display a hint with paging keys in the dialog window title
when paging is active. Recognize <Esc> as mapping to stop
paging.
Problem: vim.on_key() called for each message while cmdline is open.
Cursor is on a seemingly random column when pager is entered.
Entering the pager while the cmdline is expanded can be more
convenient than pressing "g<".
Pager window is unnecessarily clamped to half the shell height.
Setting 'laststatus' while pager is open does not adjust its
dimensions.
Solution: Only call vim.on_key() once when dialog window is opened.
Ensure cursor is at the start of the first message when
entering the pager.
Enter the pager window when "<CR>" is pressed while the
cmdline is expanded.
Don't clamp the pager window height.
Set message windows dimensions when 'laststatus' changes.
Problem:
- ~200 line function of hard-to-maintain C code.
- Local Addition section looks messy because of the varying description
formats.
Solution:
- Move code to Lua.
- Have a best-effort approach where short descriptions are right
aligned, giving a cleaner look. Long descriptions are untouched.
Problem:
Escaping logic for {subject} in ex cmd `:help {subject}` is done in a
messy 200+ lines C function which is hard to maintain and improve.
Solution:
Rewrite in Lua. Use `string.gsub()` instead of looping over characters
to improve clarity and add many more tests to be able to confidently
improve current code later on.
Problem:
Using vim.defer_fn() just before Nvim exit leaks luv handles.
Solution:
Make vim.schedule() return an error message if scheduling failed.
Make vim.defer_fn() close timer if vim.schedule() failed.
Problem:
`:lsp enable` with no arguments will fail if there is a invalid config
in `lsp/`, or if `vim.lsp.config[...]` returns nil for any other reason.
Solution:
Add a nil-check to `:lsp enable`.
Problem:
Can't use `:source` to run a Lua codeblock (treesitter injection) in
a help (vimdoc) file.
Solution:
Use treesitter to parse the range and treat it as Lua if detected as
such.
Problem:
`:lsp restart` detects when a client has exited by using the `LspDetach`
autocommand. This works correctly in common cases, but breaks when
restarting a client which is not attached to any buffer. It also breaks
if a client is detached in between `:lsp restart` and the actual
stopping of the client.
Solution:
Move restart logic into `vim/lsp/client.lua`, so it can hook in to
`_on_exit()`. The public `on_exit` callback cannot be used for this, as
`:lsp restart` needs to ensure the restart only happens once, even if
the command is run multiple times on the same client.
Problem:
We want to encourage implementing core features in Lua instead of C, but
it's clumsy because:
- Core Lua code (built into `nvim` so it is available even if VIMRUNTIME
is missing/invalid) requires manually updating CMakeLists.txt, or
stuffing it into `_editor.lua`.
- Core Lua modules are not organized similar to C modules, `_editor.lua`
is getting too big.
Solution:
- Introduce `_core/` where core Lua code can live. All Lua modules added
there will automatically be included as bytecode in the `nvim` binary.
- Move these core modules into `_core/*`:
```
_defaults.lua
_editor.lua
_options.lua
_system.lua
shared.lua
```
TODO:
- Move `_extui/ => _core/ui2/`
Problem:
The execution of startup scripts in parent directories are too late
compared to scripts in current direcctory.
Solution:
Execute all startup scripts with `lua/_core/exrc.lua`.
closes: #35147
Fixes issue on mac where it was constantly reloading buffers as paths
were not being normalized and resolved correctly (in relation to buffer
name).
Quickfix entry:
/var/folders/pt/2s7dzyw12v36tsslrghfgpkr0000gn/T/git-difftool.m95lj8/right/app.vue
Buffer name:
/private/var/folders/pt/2s7dzyw12v36tsslrghfgpkr0000gn/T/git-difftool.m95lj8/right/app.vue
/var was synlinked to /private/var and this was not being properly
handled.
Also added lazy redraw to avoid too many redraws when this happens in
future and added test for symlink handling.

Problem:
Built-in diff mode (nvim -d) does not support directory diffing
as required by git difftool -d. This makes it difficult to compare
entire directories, detect renames, and navigate changes efficiently.
Solution:
Add a DiffTool plugin and command that enables side-by-side diffing of
files and directories in Neovim. The plugin supports rename detection,
highlights changes in the quickfix list, and provides a user command for
easy invocation. This allows proper integration with git difftool -d for
directory comparison.
Example git config:
```ini
[diff]
tool = nvim_difftool
[difftool "nvim_difftool"]
cmd = nvim -c "packadd nvim.difftool" -c "DiffTool $LOCAL $REMOTE"
```
