PROBLEM:
Currently `:echoerr` prints multi-line strings in a single line
as `:echom` does (Note: `:echon` can print multi-line strings well).
This makes stacktrace printed via echoerr difficult to read.
Example code:
try
lua error("lua stacktrace")
catch
echoerr v:exception
endtry
Output:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace^@stack traceback:^@^I[C]: in function 'error'^@^I[string ":lua"]:1: in main chunk
SOLUTION:
Allow echoerr to print multiline messages (e.g., lua exceptions),
because this command is usually used to print stacktraces.
Output after the fix:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace
stack traceback:
[C]: in function 'error'
[string ":lua"]:1: in main chunk
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.
