Using fnameescape() for the path argument of findfile() and finddir() is
wrong, as fnameescape() is intended to be used for parts of Ex commands,
not function arguments.
"VimEnter foo" was accepted as a valid event name for "VimEnter".
Events delimited with commas, eg. "VimEnter,BufRead", were also
accepted, even though only the first event was actually parsed.

The 'arabicshape' feature of vim is a transformation of unicode text to
make arabic and some related scripts look better at display time. In
particular the content of a cell will be adjusted depending on the
(original) content of the cells just before and after it.
This is implemented by the arabic_shape() function in nvim. Before this
commit, shaping was invoked in four different contexts:
- when rendering buffer text in win_line()
- in line_putchar() for rendering virtual text
- as part of grid_line_puts, used by messages and statuslines and
similar
- as part of draw_cmdline() for drawing the cmdline
This replaces all these with a post-processing step in grid_put_linebuf(),
which has become the entry point for all text rendering after recent
refactors.
An aim of this is to make the handling of multibyte text yet simpler.
One of the main reasons multibyte chars needs to be "parsed" into
codepoint arrays of composing chars is so that these could be inspected
for the purpose of shaping. This can likely be vastly simplified in many
contexts where only the total length (in bytes) and width of composed
char is needed.
Problem:
On Windows, "gf" fails on a filepath that has a line:column suffix.
Example:
E447: Can't find file "src/app/core/services/identity/identity.service.ts:64:23"
Solution:
- Remove ":" from 'isfname' on Windows. Colon is not a valid filename
character (except for the drive-letter).
- Handle drive letters specially in file_name_in_line().
Fixes#25160
This finalizes the long running refactor from the old TUI-focused grid
implementation where text-drawing cursor was not separated from the
visible cursor.
Still, the pattern of setting cursor position together with updating a
line was convenient. Introduce grid_line_cursor_goto() to still allow
this but now being explicit about it.
Only having batched drawing functions makes code involving drawing
a bit longer. But it is better to be explicit, and this highlights
cases where multiple small redraws can be grouped together. This was the
case for most of the changed places (messages, lastline, and :intro)
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`.
msg_puts_display was more complex than necessary in nvim, as in
nvim, it no longer talks directly with a terminal.
In particular we don't need to scroll the grid before emiting the last
char. The TUI already takes care of things like that, for terminals
where it matters.
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 = _
Problem:
NVIM_APPNAME does not allow path separators in the name, so relative
paths can't be used:
NVIM_APPNAME="neovim-configs/first-config" nvim
NVIM_APPNAME="neovim-configs/second-config" nvim
Solution:
Let NVIM_APPNAME be a relative path. Absolute paths are not supported.

Problem:
Some steps in :Tutor don't work on Windows.
Solution:
Add support for `{unix:...,win:...}` format and transform the Tutor contents
depending on the platform.
Fix https://github.com/neovim/neovim/issues/24166
Problem:
Crash from:
set cmdheight=0 redrawdebug=invalid
resize -1
Solution:
Do not invalidate first `p_ch` `msg_grid` rows in `update_screen` when
scrolling the screen down after displaying a message, because they may
be used later for drawing cmdline.
Fixes#22154
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.
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.
Problem: Wrong curswant when clicking on empty line or with vsplits.
Solution: Don't check for ScreenCols[] before the start of the window
and handle empty line properly.

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.
If you would insert element X at position j, then if you are moving that
same element X from position i < j, you should move it to position j -
1, because you are losing an element.
This error caused a gap to be left in the array, so that it looked like
[x, null, y] instead of [x, y], where len = 2. This triggered #25147.
Fixes: #25147
