Problem:
The swapfile "E325: ATTENTION" dialog is displayed when editing a file
already open in another (running) Nvim. Usually this behavior is
annoying and irrelevant:
- "Recover" and the other options ("Open readonly", "Quit", "Abort") are
almost never wanted.
- swapfiles are less relevant for "multi-Nvim" since 'autoread' is
enabled by default.
- Even less relevant if user enables 'autowrite'.
Solution:
Define a default SwapExists handler which does the following:
1. If the swapfile is owned by a running Nvim process, automatically
chooses "(E)dit anyway" (caveat: this creates a new, extra swapfile,
which is mostly harmless and ignored except by `:recover` or `nvim -r`.
2. Shows a 1-line "ignoring swapfile..." message.
3. Users can disable the default SwapExists handler via `autocmd! nvim_swapfile`.
Problem: Visual highlight is inconsistent on a folded line with
treesitter foldtext.
Solution: Don't added Folded highlight as it is already in background.

The haskell-language-server supports resolve only for a subset of code
actions. For many code actions trying to resolve the `edit` property
results in an error, but the unresolved action already contains a
command that can be executed without issue.
The protocol specification is unfortunately a bit vague about this,
and what the haskell-language-server does seems to be valid.
Example:
newtype Dummy = Dummy Int
instance Num Dummy where
Triggering code actions on "Num Dummy" and choosing "Add placeholders
for all missing methods" resulted in:
-32601: No plugin enabled for SMethod_CodeActionResolve, potentially available: explicit-fields, importLens, hlint, overloaded-record-dot
With this change it will insert the missing methods:
instance Num Dummy where
(+) = _
(-) = _
(*) = _
negate = _
abs = _
signum = _
fromInteger = _

A lot of updated places in the docs were already incorrect since long
since they did not reflect the default behaviour.
"[dos format]" could've been argued being better for discoverability
but that ship has already sailed as it is no longer displayed by default.

Problem:
Users using `vim.lsp.start` directly (instead of nvim-lspconfig) need
more visibility for troubleshooting. For example, troubleshooting
unnecesary servers or servers that aren't attaching to expected buffers.
Solution:
Mention attached buffers in the `:checkhealth lsp` report.
Example:
vim.lsp: Active Clients ~
- clangd (id=1, root_dir=~/dev/neovim, attached_to=[7])
- lua_ls (id=2, root_dir=~/dev/neovim, attached_to=[10])
Problem:
`:checkhealth nvim` warns about missing vimrc if `init.lua` exists but
`init.vim` does not.
Solution:
Check for any of: init.vim, init.lua, $MYVIMRC.
Fix#25291
The "f" flag was removed in f7da472257.
The value of the "f" flag is no longer listed in the 'shortmess'
description and it cannot be disabled, so having it in the default value
is pointless and confusing.
Not everything needs to be crazy overconfigurable.
Also fixes a warning in latest clang which didn't approve of
the funky math switch statement in append_arg_number
This is incorrect in the following scenario:
1. The language tree is Lua > Vim > Lua.
2. An edit simultaneously wipes out the `_regions` of all nodes, while
taking the Vim injection off-screen.
3. The Vim injection is not re-parsed, so the child Lua `_regions` is
still `nil`.
4. The child Lua is assumed, incorrectly, to occupy the whole document.
5. This causes the injections to be parsed again, resulting in Lua > Vim
> Lua > Vim.
6. Now, by the same process, Vim ends up with its range assumed over the
whole document. Now the parse is broken and results in broken
highlighting and poor performance.
It should be fine to instead treat an unparsed node as occupying
nothing (i.e. effectively non-existent). Since, either:
- The parent was just parsed, hence defining `_regions`
- The parent was not just parsed, in which case this node doesn't need
to be parsed either.
Also, the name `has_regions` is confusing; it seems to simply
mean the opposite of "root" or "full_document". However, this PR does
not touch it.
- Remove the usage of the term "defer" to avoid confusion with
`vim.defer_fn`, which also calls `vim.schedule_wrap` internally.
- Explicitly state that `vim.schedule_wrap` returns a function in the
text.
- Mention that arguments are passed along.
- Include a usage example.
- Rename param to `fn`.
Fixes#24339
rust-analyzer sends "Invalid offset" error in such cases. Some other
servers handle it specially.
LSP spec mentions that "A range is comparable to a selection in an
editor". Most editors don't handle trailing newlines the same way
Neovim/Vim does, it's clearly visible if it's present or not. With that
in mind it's understandable why sending end position as simply the start
of the line after the last one is considered invalid in such cases.

Memoizes a function, using a custom function to hash the arguments.
Private for now until:
- There are other places in the codebase that could benefit from this
(e.g. LSP), but might require other changes to accommodate.
- Invalidation of the cache needs to be controllable. Using weak tables
is an acceptable invalidation policy, but it shouldn't be the only
one.
- I don't think the story around `hash_fn` is completely thought out. We
may be able to have a good default hash_fn by hashing each argument,
so basically a better 'concat'.
Previously, a screen cell would occupy 28+4=32 bytes per cell
as we always made space for up to MAX_MCO+1 codepoints in a cell.
As an example, even a pretty modest 50*80 screen would consume
50*80*2*32 = 256000, i e a quarter megabyte
With the factor of two due to the TUI side buffer, and even more when
using msg_grid and/or ext_multigrid.
This instead stores a 4-byte union of either:
- a valid UTF-8 sequence up to 4 bytes
- an escape char which is invalid UTF-8 (0xFF) plus a 24-bit index to a
glyph cache
This avoids allocating space for huge composed glyphs _upfront_, while
still keeping rendering such glyphs reasonably fast (1 hash table lookup
+ one plain index lookup). If the same large glyphs are using repeatedly
on the screen, this is still a net reduction of memory/cache
consumption. The only case which really gets worse is if you blast
the screen full with crazy emojis and zalgo text and even this case
only leads to 4 extra bytes per char.
When only <= 4-byte glyphs are used, plus the 4-byte attribute code,
i e 8 bytes in total there is a factor of four reduction of memory use.
Memory which will be quite hot in cache as the screen buffer is scanned
over in win_line() buffer text drawing
A slight complication is that the representation depends on host byte
order. I've tested this manually by compling and running this
in qemu-s390x and it works fine. We might add a qemu based solution
to CI at some point.
Problem:
With incremental injection parsing, injected languages' parsers parse
only the relevant regions and stores the result in _trees with the index
of the corresponding region. Therefore, there can be holes in _trees.
Solution:
* Use generic table functions where appropriate.
* Fix type annotations and docs.
