This is needed for #18375 for the obvious reasons.
note: verbose_terminfo_event is only temporarily needed
until the full TUI process refactor is merged.
The BufWipeout autocmd is not 100% reliable and may leave stale entries
in the cache. This is sort of a hack/workaround to ensure
`vim.diagnostic.reset` calls don't fail if there are stale cache entries
but instead clears them
Fixes errors like
Error executing vim.schedule lua callback: /usr/share/nvim/runtime/lua/vim/diagnostic.lua:1458: Invalid buffer id: 22
stack traceback:
[C]: in function 'nvim_exec_autocmds'
/usr/share/nvim/runtime/lua/vim/diagnostic.lua:1458: in function 'reset'
While `return` and `return nil` are for most intents and purposes
identical, there are situations where they're not. For example,
calculating the amount of values via the `select()` function will yield
varying results:
```lua
local function nothing() return end
local function null() return nil end
select('#', nothing()) -- 0
select('#', null()) -- 1
```
`vim.tbl_get` currently returns both nil and no results, which makes it
unreliable to use in certain situations without manually accounting for
these discrepancies.
Apply semantic token modifiers as separate extmarks with corresponding
highlight groups (e.g., `@readonly`). This is a low-effort PR to enable
the most common use cases (applying, e.g., italics or backgrounds on top
of type highlights; language-specific fallbacks like `@global.lua` are
also available). This can be replaced by more complicated selector-style
themes later on.
Instead of testing for every possible modifier type, only test bits up
to the highest set in the token array. Saves many bit ops and
comparisons when there are no modifiers or when the highest set bit is a
lower bit than the highest possible in the legend on average.
Can be further simplified when non-luaJIT gets the full bit module (see #21222)
The spec indicates that the response may be `null`, but it doesn't
really say what a `null` response means. Since neovim raises an error if
the response is `null`, I figured that ignoring it would be the safest
bet.

1. The algorithm for applying edits was slightly incorrect. It needs to
preserve the original token list as the edits are applied instead of
mutating it as it iterates. From the spec:
Semantic token edits behave conceptually like text edits on
documents: if an edit description consists of n edits all n edits are
based on the same state Sm of the number array. They will move the
number array from state Sm to Sm+1.
2. Schedule the semantic token engine start() call in the
client._on_attach() function so that users who schedule_wrap() their
config.on_attach() functions (like nvim-lspconfig does) can still
disable semantic tokens by deleting the semanticTokensProvider from
their server capabilities.

Add a "show_tree" function to view a textual representation of the
nodes in a language tree in a window. Moving the cursor in the
window highlights the corresponding text in the source buffer, and
moving the cursor in the source buffer highlights the corresponding
nodes in the window.
Add introductory guide explaining how to use Lua in Neovim:
where to put Lua files, how to set variables and options, how
to create mappings, autocommands, and user commands.

`willSaveWaitUntil` allows servers to respond with text edits before
saving a document. That is used by some language servers to format a
document or apply quick fixes like removing unused imports.
- use pcall when calling vim.secure.read from C
- catch keyboard interrupts in vim.secure.read, rethrow other errors
- selecting "view" in prompt runs :view command
- simplify lua stack cleanup with lua_gettop and lua_settop
