Problem:
vim.iter has both `rfind()` and various `*back()` methods, which work
in "reverse" or "backwards" order. It's inconsistent to have both kinds
of names, and "back" is fairly uncommon (rust) compared to python
(rfind, rstrip, rsplit, …).
Solution:
- Remove `nthback()` and let `nth()` take a negative index.
- Because `rnth()` looks pretty obscure, and because it's intuitive
for a function named `nth()` to take negative indexes.
- Rename `xxback()` methods to `rxx()`.
- This informally groups the "list-iterator" functions under a common
`r` prefix, which helps discoverability.
- Rename `peekback()` to `pop()`, in duality with the existing `peek`.
Problem:
`vim.ui.open` unnecessarily invents a different success/failure
convention. Its return type was changed in 57adf8c6e0, so we might as
well change it to have a more conventional form.
Solution:
Change the signature to use the `pcall` convention of `status, result`.
vim.fs.root() is a function for finding a project root relative to a
buffer using one or more "root markers". This is useful for LSP and
could be useful for other "projects" designs, as well as for any plugins
which work with a "projects" concept.
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.

Problem: `vim.deprecate()` can be relatively significantly slower than
the deprecated function in "Nvim" plugin.
Solution: Optimize checks for "Nvim" plugin. This also results into not
distinguishing "xxx-dev" and "xxx" versions when doing checks, which
is essentially covered by the deprecation logic itself.
With this rewrite I get the times from #28459: `{ 0.024827, 0.003797, 0.002024, 0.001774, 0.001703 }`.
For quicker reference:
- On current Nightly it is something like `{ 3.72243, 0.918169, 0.968143, 0.763256, 0.783424 }`.
- On 0.9.5: `{ 0.002955, 0.000361, 0.000281, 0.000251, 0.00019 }`.
Problem:
We need to establish a pattern for `enable()`.
Solution:
- First `enable()` parameter is always `enable:boolean`.
- Update `vim.diagnostic.enable()`
- Update `vim.lsp.inlay_hint.enable()`.
- It was not released yet, so no deprecation is needed. But to help
HEAD users, it will show an informative error.
- vim.deprecate():
- Improve message when the "removal version" is a *current or older* version.
Problem:
vim.diagnostic.enable() does not match the signature of vim.lsp.inlay_hint.enable()
Solution:
- Change the signature so that the first 2 args are (bufnr, enable).
- Introduce a 3rd `opts` arg.
- Currently it only supports `opts.ns_id`.
Problem:
`vim.diagnostic.is_disabled` and `vim.diagnostic.disable` are unnecessary
and inconsistent with the "toggle" pattern (established starting with
`vim.lsp.inlay_hint`, see https://github.com/neovim/neovim/pull/25512#pullrequestreview-1676750276
As a reminder, the rationale is:
- we always need `enable()`
- we always end up needing `is_enabled()`
- "toggle" can be achieved via `enable(not is_enabled())`
- therefore,
- `toggle()` and `disable()` are redundant
- `is_disabled()` is a needless inconsistency
Solution:
- Introduce `vim.diagnostic.is_enabled`, and `vim.diagnostic.enable(…, enable:boolean)`
- Note: Future improvement would be to add an `enable()` overload `enable(enable:boolean, opts: table)`.
- Deprecate `vim.diagnostic.is_disabled`, `vim.diagnostic.disable`
Problem:
vim.ui.open "locks up" Nvim if the spawned process does not terminate. #27986
Solution:
- Change `vim.ui.open()`:
- Do not call `wait()`.
- Return a `SystemObj`. The caller can decide if it wants to `wait()`.
- Change `gx` to `wait()` only a short time.
- Allows `gx` to show a message if the command fails, without the
risk of waiting forever.
Also close Nvim instance before removing log file, otherwise the Nvim
instance will still write to the log file.
Also adjust log level in libuv_process_spawn(). Ref #27660
Design
- Enable commenting support only through `gc` mappings for simplicity.
No ability to configure, no Lua module, no user commands. Yet.
- Overall implementation is a simplified version of 'mini.comment'
module of 'echasnovski/mini.nvim' adapted to be a better suit for
core. It basically means reducing code paths which use only specific
fixed set of plugin config.
All used options are default except `pad_comment_parts = false`. This
means that 'commentstring' option is used as is without forcing single
space inner padding.
As 'tpope/vim-commentary' was considered for inclusion earlier, here is
a quick summary of how this commit differs from it:
- **User-facing features**. Both implement similar user-facing mappings.
This commit does not include `gcu` which is essentially a `gcgc`.
There are no commands, events, or configuration in this commit.
- **Size**. Both have reasonably comparable number of lines of code,
while this commit has more comments in tricky areas.
- **Maintainability**. This commit has (purely subjectively) better
readability, tests, and Lua types.
- **Configurability**. This commit has no user configuration, while
'vim-commentary' has some (partially as a counter-measure to possibly
modifying 'commentstring' option).
- **Extra features**:
- This commit supports tree-sitter by computing `'commentstring'`
option under cursor, which can matter in presence of tree-sitter
injected languages.
- This commit comments blank lines while 'tpope/vim-commentary' does
not. At the same time, blank lines are not taken into account when
deciding the toggle action.
- This commit has much better speed on larger chunks of lines (like
above 1000). This is thanks to using `nvim_buf_set_lines()` to set
all new lines at once, and not with `vim.fn.setline()`.
`exec_lua` makes code slighly harder to read, so it's beneficial to
remove it in cases where it's possible or convenient.
Not all `exec_lua` calls should be removed even if the test passes as it
changes the semantics of the test even if it happens to pass.
From https://github.com/neovim/neovim/pull/28155#discussion_r1548185779:
"Note for tests like this, which fundamentally are about conversion, you
end up changing what conversion you are testing. Even if the result
happens to be same (as they often are, as we like the rules to be
consistent if possible), you are now testing the RPC conversion rules
instead of the vim script to in-process lua conversion rules."
From https://github.com/neovim/neovim/pull/28155#discussion_r1548190152:
"A test like this specifies that the cursor is valid immediately and not
after a separate cycle of normal (or an other input-processing) mode."
Backslashes are valid characters in unix style paths.
Fix the conversion of backslashes to forward slashes in several `vim.fs`
functions when not on Windows. On Windows, backslashes will still be converted
to forward slashes.
When the edited file is a symlink, the unexpanded file name is needed to
to achieve the same behavior as the autocommand pattern matching in Vim.
Neither args.file nor args.match are guaranteed to be unexpanded, so use
bufname() instead.
A lot of functions in move.c only worked for curwin, alternatively
took a `wp` arg but still only work if that happens to be curwin.
Refactor those that are needed for update_topline(wp) to work
for any window.

Problem: Crash on exit with EXITFREE and using win_execute().
Solution: Also save and restore tp_topframe. (issue vim/vim#9374)
dab17a0689
Couldn't repro the crash in the test, but I only care about this patch so
switch_win sets topframe properly for win_split_ins in nvim_open_win and
nvim_win_set_config.
Add a test using nvim_win_call and :wincmd, as I couldn't repro the issue via
nvim_open_win or nvim_win_set_config (though it's clear they're affected by this
patch).
That said, at that point, could just use {un}use_tabpage inside switch_win
instead, which also updates tp_curwin (though maybe continue to not set it in
restore_win). That would also fix possible inconsistent behaviour such as:
:call win_execute(w, "let curwin_nr1 = tabpagewinnr(1)")
:let curwin_nr2 = tabpagewinnr(1)
Where it's possible for curwin_nr1 != curwin_nr2 if these commands are run from
the 1st tabpage, but window "w" is in the 2nd (as the 1st tabpage's tp_curwin
may still be invalid). I'll probably PR a fix for that later in Vim.

Problem:
vim._watch.watchdirs has terrible performance.
Solution:
- On linux use fswatch as a watcher backend if available.
- Add File watcher section to health:vim.lsp. Warn if watchfunc is
libuv-poll.
Problem: Some LSP servers return `textDocument/documentLink` responses
containing file URIs with line/column numbers in the fragment.
`vim.uri_to_fname` returns invalid file names for these URIs.
Solution: Remove the URI fragment from file URIs.
Currently, highlight.on_yank() does buffer-local highlighting, this PR
makes it window scoped.
Also fix the problem that when yanking in a buffer, moving to another
buffer, and yanking before the original buffer highlight disappears, the
original buffer highlight won't disappear on timeout.
