The newer UCRT runtime has native support for UTF-8, including forcing
it as the active codepage even before `main()` is called. This means
the c runtime will properly convert windows WCHAR:s into UTF-8 bytes,
as early as the argv/argc params to `main()` . Whereas MSVCRT does not
support this reliably and required us to use `wmain()`.
Only MSVC supports using manifest files directly as source files.
The solution for other Windows toolchains is to use a .rc file.
Problem:
Since [version 3.17](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocuments),
LSP supports specifying the position encoding (aka offset encoding) supported by
the client through `positionEncoding`. Since #31209, Nvim fully supports
`utf-8`, `utf-16`, and `utf-32` encodings.
Previously, nvim assumed all clients for a buffer had the same
`offset_encoding`, so:
* Nvim provides `vim.lsp._get_offset_encoding()` to get `offset_encoding`, but
this function is incorrect because `offset_encoding` is per-client, not
per-buffer.
* Based on the strategy of `vim.lsp._get_offset_encoding()`,
`vim.lsp.util.make_position_params()`, `vim.lsp.util.make_range_params()`, and
`vim.lsp.util.make_given_range_params()` do not require the caller to pass
`offset_encoding`, which is invalid.
* https://github.com/neovim/neovim/issues/25272
Solution:
* Mark `vim.lsp._get_offset_encoding()` as `@deprecated`.
* Change the type annotations of `vim.lsp.util.make_position_params()`,
`vim.lsp.util.make_range_params()`, `vim.lsp.util.make_given_range_params()`
to require the `offset_encoding` param.
**Problem:** Despite the LSP providing the option for language servers
to specify a range with a hover response (for highlighting), Neovim does
not give the option to highlight this range.
**Solution:** Add an option to `buf.hover()` which causes this range to
be highlighted.

Problem: message history is fixed to 200
Solution: Add the 'msghistory' option, increase the default

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.
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.
- Partition the handlers in vim.lsp.handlers as:
- client to server response handlers (RCS)
- server to client request handlers (RSC)
- server to client notification handlers (NSC)
Note use string indexes instead of protocol.methods for improved
typing in LuaLS (tip: use hover on RCS, RSC or NSC).
feat(diagnostics)!: sort underline with severity_sort
BREAKING CHANGE: underline will be applied with a higher value than `vim.hl.priorities.diagnostics`
* deprecate old signatures
* move to new str_byteindex/str_utfindex signature
* use single-underscore name (double-underscore is reserved for Lua itself)
Problem: We use `void *` for option default values, which is confusing and can cause problems with type-correctness. It also doesn't accomodate for multitype options. On top of that, it also leads to default boolean option values not behaving correctly on big endian systems.
Solution: Use `OptVal` for option default values.
BREAKING CHANGE:
- `:set {option}<` removes the local value for all global-local options instead of just string global-local options.
- `:setlocal {option}<` copies the global value to the local value for number and boolean global-local options instead of removing the local value.
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.
vim-patch:8.2.4744: a terminal window can't use the bell
vim-patch:8.2.4745: using wrong flag for using bell in the terminal
BREAKING CHANGE: Bells from :terminal are now silent by default, unless
'belloff' option doesn't contain "term" or "all".
Problem:
If there are multiple LSP clients, it's not clear which actions are provided by which servers. #30710
Solution:
Show the server name next to each action (only if there are multiple clients).
This commit also marks `child_containing_descendant()` as deprecated
(per upstream's documentation), and uses `child_with_descendant()` in
its place. Minimum required tree-sitter version will now be `0.24`.
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: No clear way to check whether parsers are available for a given
language.
Solution: Make `language.add()` return `true` if a parser was
successfully added and `nil` otherwise. Use explicit `assert` instead of
relying on thrown errors.
Problem: Language names are only registered for filetype<->language
lookups when parsers are actually loaded; this means users cannot rely
on `vim.treesitter.language.get_lang()` or `get_filetypes()` to return
the correct value when language and filetype coincide and always need to
add explicit fallbacks.
Solution: Always return the language name as valid filetype in
`get_filetypes()`, and default to the filetype in `get_lang()`. Document
this behavior.
Problem:
Headings in :help do not stand out visually.
Solution:
Define a non-standard `@markup.heading.1.delimiter` group and
special-case it in `highlight_group.c`.
FUTURE:
This is a cheap workaround until we have #25718 which will enable:
- fully driven by `vimdoc/highlights.scm` instead of using highlight
tricks (`guibg=bg guifg=bg guisp=fg`)
- better support of "cterm" ('notermguicolors')
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.
Problem:
The default builtin UI client does not declare its client info. This
reduces discoverability and makes it difficult for plugins to identify
the UI.
Solution:
- Call nvim_set_client_info after attaching, as recommended by `:help dev-ui`.
- Also set the "pid" field.
- Also change `ui_active()` to return a count. Not directly relevant to
this commit, but will be useful later.
