Create mapping to most of the C spec and some POSIX specific functions.
This is more robust than relying files shipped with IWYU.

We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.

Problem: The style guide states that all switch statements that are not conditional on an enum must have a `default` case, but does not give any explicit guideline for switch statements that are conditional on enums. As a result, a `default` case is added in many enum switch statements, even when the switch statement is exhaustive. This is not ideal because it removes the ability to have compiler errors to easily detect unchanged switch statements when a new possible value for an enum is added.
Solution: Add explicit guidelines for switch statements that are conditional on an enum, clarifying that a `default` case is not necessary if the switch statement is exhaustive. Also refactor pre-existing code with unnecessary `default` cases.

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.

Problem: No clear separation of floating title and footer highlighting.
Solution: Add new `FloatFooter` highlight group.
|
| |
|
|
|
|
|
|
| |
Problem: Now way to show text at the bottom part of floating window
border (a.k.a. "footer").
Solution: Allows `footer` and `footer_pos` config fields similar to
`title` and `title_pos`.

Problem: As discussed on Matrix, there was some interest in having
`nvim_open_win` again be able to open floats in the cmdwin (e.g: displaying a
hover doc related to what's in the cmdwin). After #23228, this was disallowed.
Solution: Allow `nvim_open_win` in the cmdwin as long as `!enter` and
`buffer != curbuf` (the former can cause all sorts of issues, and the latter
can crash Nvim after closing cmdwin). Also allow `nvim_win_set_buf` in a similar
fashion.
Note that we're not *entirely* sure if this is 100% safe (cmdwin is a
global-state-using-main-loop-calling beast), but this seems to work OK..?
Also:
- Check the buffer argument of `nvim_open_win` earlier, and abort if it's
invalid (it used to still open a window in this case).
- Untranslate `e_cmdwin` errors in the API (other errors in the API are not
translated: although not detailed in the API contract yet, errors are
supposed to be stable).

Problem: some API functions that check textlock (usually those that can change
curwin or curbuf) can break the cmdwin.
Solution: make FUNC_API_CHECK_TEXTLOCK call text_locked() instead, which already
checks for textlock, cmdwin and `<expr>` status.
Add FUNC_API_TEXTLOCK_ALLOW_CMDWIN to allow such functions to be usable in the
cmdwin if they can work properly there; the opt-in nature of this attribute
should hopefully help mitigate future bugs.
Also fix a regression in #22634 that made functions checking textlock usable in
`<expr>` mappings, and rename FUNC_API_CHECK_TEXTLOCK to FUNC_API_TEXTLOCK.

Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.

Problem:
No easy way to position a LSP hover window relative to mouse.
Solution:
Introduce another option to the `relative` key in `nvim_open_win()`.
With this PR it should be possible to override the handler and do something
similar to this https://github.com/neovim/neovim/pull/19481#issuecomment-1193248674
to have hover information displayed from the mouse.
Test case:
```lua
local util = require('vim.lsp.util')
local function make_position_param(window, offset_encoding)
window = window or 0
local buf = vim.api.nvim_win_get_buf(window)
local row, col
local mouse = vim.fn.getmousepos()
row = mouse.line
col = mouse.column
offset_encoding = offset_encoding or util._get_offset_encoding(buf)
row = row - 1
local line = vim.api.nvim_buf_get_lines(buf, row, row + 1, true)[1]
if not line then
return { line = 0, character = 0 }
end
if #line < col then
return { line = 0, character = 0 }
end
col = util._str_utfindex_enc(line, col, offset_encoding)
return { line = row, character = col }
end
local make_params = function(window, offset_encoding)
window = window or 0
local buf = vim.api.nvim_win_get_buf(window)
offset_encoding = offset_encoding or util._get_offset_encoding(buf)
return {
textDocument = util.make_text_document_params(buf),
position = make_position_param(window, offset_encoding),
}
end
local hover_timer = nil
vim.o.mousemoveevent = true
vim.keymap.set({ '', 'i' }, '<MouseMove>', function()
if hover_timer then
hover_timer:close()
end
hover_timer = vim.defer_fn(function()
hover_timer = nil
local params = make_params()
vim.lsp.buf_request(
0,
'textDocument/hover',
params,
vim.lsp.with(vim.lsp.handlers.hover, {
silent = true,
focusable = false,
relative = 'mouse',
})
)
end, 500)
return '<MouseMove>'
end, { expr = true })
```

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
