Problem: Lua callbacks for "msg_show" events with vim.ui_attach() are
executed when it is not safe.
Solution: Disallow non-fast API calls for "msg_show" event callbacks.
Automatically detach callback after excessive errors.
Make sure fast APIs do not modify Nvim state.
Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.
Problem: Ext_messages chunks only contain the highlight attr id, which
is not very useful for vim.ui_attach() consumers.
Solotion: Add highlight group id to message chunks, which can easily be
used to highlight text in the TUI through nvim_buf_set_extmark():
hl_group = synIDattr(id, "name").
Problem:
There are three different ways of marking an option as hidden, `enable_if
= false`, `hidden = true` and `immutable = true`. These also have different
behaviors. Options hidden with `enable_if = false` can't have their value
fetched using Vim script or the API, but options hidden with `hidden = true` or
`immutable = true` can. On the other hand, options with `hidden = true` do not
error when trying to set their value, but options with `immutable = true` do.
Solution:
Remove `enable_if = false`, remove the `hidden` property for options, and use
`immutable = true` to mark an option as hidden instead. Also make hidden option
variable pointers always point to the default value, which allows fetching the
value of every hidden option using Vim script and the API. This does also mean
that trying to set a hidden option will now give an error instead of just being
ignored.
feat(diagnostics)!: sort underline with severity_sort
BREAKING CHANGE: underline will be applied with a higher value than `vim.hl.priorities.diagnostics`
PROBLEM:
There are several limitations to vim.str_byteindex, vim.str_utfindex:
1. They throw given out-of-range indexes. An invalid (often user/lsp-provided)
index doesn't feel exceptional and should be handled by the caller.
`:help dev-error-patterns` suggests that `retval, errmsg` is the preferred
way to handle this kind of failure.
2. They cannot accept an encoding. So LSP needs wrapper functions. #25272
3. The current signatures are not extensible.
* Calling: The function currently uses a fairly opaque boolean value to
indicate to identify the encoding.
* Returns: The fact it can throw requires wrapping in pcall.
4. The current name doesn't follow suggestions in `:h dev-naming` and I think
`get` would be suitable.
SOLUTION:
- Because these are performance-sensitive, don't introduce `opts`.
- Introduce an "overload" that accepts `encoding:string` and
`strict_indexing:bool` params.
```lua
local col = vim.str_utfindex(line, encoding, [index, [no_out_of_range]])
```
Support the old versions by dispatching on the type of argument 2, and
deprecate that form.
```lua
vim.str_utfindex(line) -- (utf-32 length, utf-16 length), deprecated
vim.str_utfindex(line, index) -- (utf-32 index, utf-16 index), deprecated
vim.str_utfindex(line, 'utf-16') -- utf-16 length
vim.str_utfindex(line, 'utf-16', index) -- utf-16 index
vim.str_utfindex(line, 'utf-16', math.huge) -- error: index out of range
vim.str_utfindex(line, 'utf-16', math.huge, false) -- utf-16 length
```
Problem:
`vim.validate()` takes two forms when it only needs one.
Solution:
- Teach the fast form all the features of the spec form.
- Deprecate the spec form.
- General optimizations for both forms.
- Add a `message` argument which can be used alongside or in place
of the `optional` argument.
Problem:
- `vim.highlight` module does not follow `:help dev-name-common`, which
documents the name for "highlight" as "hl".
- Shorter names are usually preferred.
Solution:
Rename `vim.highlight` to `vim.hl`.
This is not a breaking change until 2.0 (or maybe never).
Problem: Lua accessors for
- global, local, and special variables (`vim.{g,t,w,b,v}.*`), and
- options (`vim.{o,bo,wo,opt,opt_local,opt_global}.*`),
do not have command-line completion, unlike their vimscript counterparts
(e.g., `g:`, `b:`, `:set`, `:setlocal`, `:call <fn>`, etc.).
Completion for vimscript functions (`vim.fn.*`) is incomplete and does
not list all the available functions.
Solution: Implement completion for vimscript function, variable and
option accessors in `vim._expand_pat` through:
- `getcompletion()` for variable and vimscript function accessors, and
- `nvim_get_all_options_info()` for option accessors.
Note/Remark:
- Short names for options are yet to be implemented.
- Completions for accessors with handles (e.g. `vim.b[0]`, `vim.wo[0]`)
are also yet to be implemented, and are left as future work, which
involves some refactoring of options.
- For performance reasons, we may want to introduce caching for
completing options, but this is not considered at this time since the
number of the available options is not very big (only ~350) and Lua
completion for option accessors appears to be pretty fast.
- Can we have a more "general" framework for customizing completions?
In the future, we may want to improve the implementation by moving the
core logic for generating completion candidates to each accessor (or
its metatable) or through some central interface, rather than writing
all the accessor-specific completion implementations in a single
function: `vim._expand_pat`.
Problem:
The `_watch.watch()` strategy may fail if the given path does not exist:
…/vim/_watch.lua:101: ENOENT: no such file or directory
stack traceback:
[C]: in function 'assert'
…/vim/_watch.lua:101: in function <…/vim/_watch.lua:61>
[string "<nvim>"]:5: in main chunk
- `_watch.watch()` actively asserts any error returned by `handle:start()`.
- whereas `_watch.watchdirs()` just ignores the result of `root_handle:start()`.
Servers may send "client/registerCapability" with "workspace/didChangeWatchedFiles"
item(s) (`baseUri`) which do not actually exist on the filesystem:
https://github.com/neovim/neovim/issues/28058#issuecomment-2189929424
{
method = "client/registerCapability",
params = {
registrations = { {
method = "workspace/didChangeWatchedFiles",
registerOptions = {
watchers = { {
globPattern = {
baseUri = "file:///Users/does/not/exist",
pattern = "**/*.{ts,js,mts,mjs,cjs,cts,json,svelte}"
}
},
...
}
Solution:
- Remove the assert in `_watch.watch()`.
- Show a once-only message for both cases.
- More detailed logging is blocked until we have `nvim_log` / `vim.log`.
fix#28058
Problem:
Linematch used to use strchr to navigate a string, however strchr does
not supoprt embedded NULs.
Solution:
Use `mmfile_t` instead of `char *` in linematch and introduce `strnchr()`.
Also remove heap allocations from `matching_char_iwhite()`
Fixes: #30505
In the api_info() output:
:new|put =map(filter(api_info().functions, '!has_key(v:val,''deprecated_since'')'), 'v:val')
...
{'return_type': 'ArrayOf(Integer, 2)', 'name': 'nvim_win_get_position', 'method': v:true, 'parameters': [['Window', 'window']], 'since': 1}
The `ArrayOf(Integer, 2)` return type didn't break clients when we added
it, which is evidence that clients don't use the `return_type` field,
thus renaming Dictionary => Dict in api_info() is not (in practice)
a breaking change.
- `alter_slashes` belongs in `testutil.lua`, not `testnvim.lua`.
- `alter_slashes` is an unusual name. Rename it to `fix_slashes`.
- invert its behavior, to emphasize that `/` slashes are the preferred,
pervasive convention, not `\` slashes.
Problem: vim.tbl_deep_extend had an undocumented feature where arrays
(integer-indexed tables) were not merged but compared literally (used
for merging default and user config, where one list should overwrite the
other completely). Turns out this behavior was relied on in quite a
number of plugins (even though it wasn't a robust solution even for that
use case, since lists of tables (e.g., plugin specs) can be array-like
as well).
Solution: Revert the removal of this special feature. Check for
list-like (contiguous integer indices) instead, as this is closer to the
intent. Document this behavior.
- The exclusion of lists was never justified in the commit history and is
the wrong thing to do for a function that deals with tables.
- Move the error checks out of the recursive path.
Fixes#23654
Problem:
137f98cf64 added the `create` parameter to `tmpname()` but didn't
fully implement it.
Solution:
- Update impl for the `os.tmpname()` codepath.
- Inspect all usages of `tmpname()`, update various tests.
Lua's string.byte has a maximum (undocumented) allowable length, so
vim.text.hencode fails on large strings with the error "string slice too
long".
Instead of converting the string to an array of bytes up front, convert
each character to a byte one at a time.
Problem:
Tests have lots of exec_lua calls which input blocks of code
provided as unformatted strings.
Solution:
Teach exec_lua how to handle functions.
Problem:
Empty dictionaries are converted into typed tables of the form `{ [true]
= 6}` instead of an empty dictionary representation `{}`. This leads to
incorrect table representation, along with failure in JSON encoding of
such tables as currently tables with only string and number type keys
can be encoded.
Solution:
The typed table logic has been removed from `nlua_push_Dictionary`. The
typed table logic is required only for float value conversions which is
already handled in `nlua_push_Float`. So, it is(was) no longer required
here.

This patch replaces fswatch with inotifywait from inotify-toools:
https://github.com/inotify-tools/inotify-tools
fswatch takes ~1min to set up recursively for the Samba source code
directory. inotifywait needs less than a second to do the same thing.
https://github.com/emcrisostomo/fswatch/issues/321
Also it fswatch seems to be unmaintained in the meantime.

This is a breaking change which will make refactor of typval and shada
code a lot easier. In particular, code that would use or check for
v:msgpack_types.binary in the wild would be broken. This appears to be
rarely used in existing plugins.
Also some cases where v:msgpack_type.string would be used to represent a
binary string of "string" type, we use a BLOB instead, which is
vimscripts native type for binary blobs, and already was used for BIN
formats when necessary.
msgpackdump(msgpackparse(data)) no longer preserves the distinction
of BIN and STR strings. This is very common behavior for
language-specific msgpack bindings. Nvim uses msgpack as a tool to
serialize its data. Nvim is not a tool to bit-perfectly manipulate
arbitrary msgpack data out in the wild.
The changed tests should indicate how behavior changes in various edge
cases.
Problem: with a single `context.options` there is no way for user to
force which scope (local, global, both) is being temporarily set and
later restored.
Solution: replace single `options` context with `bo`, `go`, `wo`, and
`o`. Naming and implementation follows how options can be set directly
with `vim.*` (like `vim.bo`, etc.).
Options are set for possible target `win` or `buf` context.
