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
Oldtests clean up after themselves, and the options that need operators
to align with Vim all deny duplicates, so there is no need to set them
to default.
Also make the variable name that test_listchars.vim uses to align with
Vim more obvious.
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
PROBLEM: The builtin python3 provider cannot auto-detect python3.12
when g:python3_host_prog is not set. As a result, when python3 on $PATH
is currently python 3.12, neovim will fail to load python3 provider
and result in `has("python3") == 0`, e.g.,
"Failed to load python3 host. You can try to see what happened by ..."
ROOT CAUSE: the `system()` call from `provider#pythonx#DetectByModule`
does not ignore python warnings, and `pkgutil.get_loader` will print
a warning message in the very first line:
```
<string>:1: DeprecationWarning: 'pkgutil.get_loader' is deprecated and
slated for removal in Python 3.14; use importlib.util.find_spec() instead
```
SOLUTION:
- Use `importlib.util.find_spec` instead (python >= 3.4)
- Use `-W ignore` option to prevent any potential warning messages
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.
patch 9.0.1918: No filetype detection for Authzed filetypes
Problem: No filetype detection for Authzed filetypes
Solution: Detect the *.zed file extension as authzed filetype

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'.
Problem: r_CTRL-C works differently in visual mode
Solution: Make r_CTRL-C behave consistent in visual mode
in terminal and Windows GUI
in visual mode, r CTRL-C behaves strange in Unix like environments. It
seems to end visual mode, but still is waiting for few more chars,
however it never seems to replace it by any characters and eventually
just returns back into normal mode.
In contrast in Windows GUI mode, r_CTRL-C replaces in the selected area
all characters by a literal CTRL-C.
Not sure why it behaves like this. It seems in the Windows GUI, got_int
is not set and therefore behaves as if any other normal character has
been pressed.
So remove the special casing of what happens when got_int is set and
make it always behave like in Windows GUI mode. Add a test to verify it
always behaves like replacing in the selected area each selected
character by a literal CTRL-C.

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.
runtime(netrw): fix filetype detection for remote editing files

this partially reverses commit 71badf9 by commenting out the line that
intentionally sets the filetype to an empty string.

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.
Problem:
It doesn't make much sense to flatten each region (= list of ranges).
This coincidentally worked for region with a single range.
Solution:
Custom function for combining regions.
Problem
---
If a highlighter query returns a significant number of predicate
non-matches, the highlighter will scan well past the end of the window.
Solution
---
In the iterator returned from `iter_captures`, accept an optional
parameter `end_line`. If no parameter provided, the behavior is
unchanged, hence this is a non-invasive tweak.
Fixes: #25113nvim-treesitter/nvim-treesitter#5057
The name for_each_child is misleading and caused bugs.
After #25111, #25115, there are no more usages of `for_each_child` in Nvim.
In the future if we want to restore this functionality we can consider a
generalized vim.traverse(node, key, visitor) function.
