Instead of adding all diagnostics matching lnum filters to a table, and
then copying that table to another table while applying the severity
filter, this changes the flow to only add diagnostics matching both
filters in the first pass.
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:
Besides being redundant with vim.iter():flatten(), `tbl_flatten` has
these problems:
- Has `tbl_` prefix but only accepts lists.
- Discards some results! Compare the following:
- iter.flatten():
```
vim.iter({1, { { a = 2 } }, { 3 } }):flatten():totable()
```
- tbl_flatten:
```
vim.tbl_flatten({1, { { a = 2 } }, { 3 } })
```
Solution:
Deprecate tbl_flatten.
Note:
iter:flatten() currently fails ("flatten() requires a list-like table")
on this code from gen_lsp.lua:
local anonym = vim.iter({ -- remove nil
anonymous_num > 1 and '' or nil,
'---@class ' .. anonymous_classname,
}):flatten():totable()
Should we enhance :flatten() to work for arrays?
Problem:
While the fold level computation is incremental, the evaluation of the
foldexpr is done on the full buffer. Despite that the foldexpr reads
from the cache, it can take tens of milliseconds for moderately big (10K
lines) buffers.
Solution:
Track the range of lines on which the foldexpr should be evaluated.
Problem:
The use-case for the convenience functions vim.iter.map(),
vim.iter.filter(), vim.iter.totable() is not clear.
Solution:
Drop them for now. We can revisit after 0.10 release.
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:
The order of the validation performed by vim.validate() is
unpredictable.
- harder to write reliable tests.
- confusing UX because validation result might return different errors randomly.
Solution:
Iterate the input using `vim.spairs()`.
Future:
Ideally, the caller could provide an "ordered dict".
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.
Problem: noautocmd is confusing; despite its name, it doesn't block all
autocommands (instead it blocks only those related to setting the buffer), and
is commonly used by plugins to open windows while producing minimal
side-effects.
Solution: be consistent and block all autocommands when noautocmd is set.
This includes WinNew (again), plus autocommands from entering the window (if
enter is set) like WinEnter, WinLeave, TabEnter, .etc.
See the discussion at https://github.com/neovim/neovim/pull/14659#issuecomment-2040029517
for more information.
Remove win_set_buf's noautocmd argument, as it's no longer needed.
NOTE: pum_create_float_preview sets noautocmd for win_set_buf, but all its
callers already use block_autocmds.
Despite that, pum_create_float_preview doesn't actually properly handle
autocommands (it has no checks for whether those from win_enter or
nvim_create_buf free the window).
For now, ensure autocommands are blocked within it for correctness (in case it's
ever called outside of a block_autocmds context; the function seems to have been
refactored in #26739 anyway).
Problem:
The `:terminal` auto-close logic does not support `&shell` that has
arguments, e.g., `/bin/bash -O globstar`.
Solution:
Join `argv` and match `&shell`. This is not perfect since `&shell` may
contain irregular spaces and quotes, but it seems to be good enough.
This reverts commit 4382d2ed56.
The story for this feature was left in an incomplete state. It was never
the intention to unilaterally fold all information, only the ones that
did not contain relevant information. This feature does more harm than
good in its incomplete state.
