* fix(PVS/V002): disable rule completely
V002: "Some diagnostic messages may contain incorrect line number in
this file." This particular check seems unreliable. It says on their
website https://pvs-studio.com/en/docs/warnings/v002/ that this warning
occurs when there are multiline pragmas, but there are none in
extmark.c.
* fix(PVS/V756): ignore "counter is not used inside a nested loop" warning
The nested loop starts with "AutoCmd *ac = ap->cmds" so "ap" is
definitely used.
* fix(PVS/V560): disable "a part of conditional expression is always true"
* fix(PVS/V614): potentially uninitialized variable 'blen' used
Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,

Name the new file highlight_group.c instead.

Previously, `delete_lines_below` would raise `FileNotFoundError` when
adding a new file to `CONFIG` and you had to manually write a file with
help tag of the first section as placeholder. This change relieves you
of that need.
Using a here string can cause an error if there are no missing patches:
`./scripts/vim-patch.sh: line 580: runtime_commits: bad array subscript`
Using piping doesn't cause the error.
This introduces two new functions `vim.keymap.set` & `vim.keymap.del`
differences compared to regular set_keymap:
- remap is used as opposite of noremap. By default it's true for <Plug> keymaps and false for others.
- rhs can be lua function.
- mode can be a list of modes.
- replace_keycodes option for lua function expr maps. (Default: true)
- handles buffer specific keymaps
Examples:
```lua
vim.keymap.set('n', 'asdf', function() print("real lua function") end)
vim.keymap.set({'n', 'v'}, '<leader>lr', vim.lsp.buf.references, {buffer=true})
vim.keymap.set('n', '<leader>w', "<cmd>w<cr>", {silent = true, buffer = 5 })
vim.keymap.set('i', '<Tab>', function()
return vim.fn.pumvisible() == 1 and "<C-n>" or "<Tab>"
end, {expr = true})
vim.keymap.set('n', '[%', '<Plug>(MatchitNormalMultiBackward)')
vim.keymap.del('n', 'asdf')
vim.keymap.del({'n', 'i', 'v'}, '<leader>w', {buffer = 5 })
```
Problem:
Because of -u NORC, vim-patch.sh would hang on my machine due to one of my
plugins (start package) waiting for prompt input.
Solution:
- Use -u NONE instead to disable all plugins.
- Also use -n to disable swapfiles. These changes only apply to the --headless
nvim instances used to process things.
The spacing fix drew attention to a couple of places that were using
incorrect formatting such as the key listing for `nvim_open_win`, so
those were fixed too.
Continuation of https://github.com/neovim/neovim/pull/15202
A plugin like telescope could override it with a fancy implementation
and then users would get the telescope-ui within each plugin that
utilizes the vim.ui.select function.
There are some plugins which override the `textDocument/codeAction`
handler solely to provide a different UI. With custom client commands and
soon codeAction resolve support, it becomes more difficult to implement
the handler right - so having a dedicated way to override the picking
function will be useful.

## Overview
- Move vim.lsp.diagnostic to vim.diagnostic
- Refactor client ids to diagnostic namespaces
- Update tests
- Write/update documentation and function signatures
Currently, non-LSP diagnostics in Neovim must hook into the LSP subsystem. This
is what e.g. null-ls and nvim-lint do. This is necessary because none of the
diagnostic API is exposed separately from the LSP subsystem.
This commit addresses this by generalizing the diagnostic subsystem beyond the
scope of LSP. The `vim.lsp.diagnostic` module is now simply a specific
diagnostic producer and primarily maintains the interface between LSP clients
and the broader diagnostic API.
The current diagnostic API uses "client ids" which only makes sense in the
context of LSP. We replace "client ids" with standard API namespaces generated
from `nvim_create_namespace`.
This PR is *mostly* backward compatible (so long as plugins are only using the
publicly documented API): LSP diagnostics will continue to work as usual, as
will pseudo-LSP clients like null-ls and nvim-lint. However, the latter can now
use the new interface, which looks something like this:
```lua
-- The namespace *must* be given a name. Anonymous namespaces will not work with diagnostics
local ns = vim.api.nvim_create_namespace("foo")
-- Generate diagnostics
local diagnostics = generate_diagnostics()
-- Set diagnostics for the current buffer
vim.diagnostic.set(ns, diagnostics, bufnr)
```
Some public facing API utility methods were removed and internalized directly in `vim.diagnostic`:
* `vim.lsp.util.diagnostics_to_items`
## API Design
`vim.diagnostic` contains most of the same API as `vim.lsp.diagnostic` with
`client_id` simply replaced with `namespace`, with some differences:
* Generally speaking, functions that modify or add diagnostics require a namespace as their first argument, e.g.
```lua
vim.diagnostic.set({namespace}, {bufnr}, {diagnostics}[, {opts}])
```
while functions that read or query diagnostics do not (although in many cases one may be supplied optionally):
```lua
vim.diagnostic.get({bufnr}[, {namespace}])
```
* We use our own severity levels to decouple `vim.diagnostic` from LSP. These
are designed similarly to `vim.log.levels` and currently include:
```lua
vim.diagnostic.severity.ERROR
vim.diagnostic.severity.WARN
vim.diagnostic.severity.INFO
vim.diagnostic.severity.HINT
```
In practice, these match the LSP diagnostic severity levels exactly, but we
should treat this as an interface and not assume that they are the same. The
"translation" between the two severity types is handled transparently in
`vim.lsp.diagnostic`.
* The actual "diagnostic" data structure is: (**EDIT:** Updated 2021-09-09):
```lua
{
lnum = <number>,
col = <number>,
end_lnum = <number>,
end_col = <number>,
severity = <vim.diagnostic.severity>,
message = <string>
}
```
This differs from the LSP definition of a diagnostic, so we transform them in
the handler functions in vim.lsp.diagnostic.
## Configuration
The `vim.lsp.with` paradigm still works for configuring how LSP diagnostics are
displayed, but this is a specific use-case for the `publishDiagnostics` handler.
Configuration with `vim.diagnostic` is instead done with the
`vim.diagnostic.config` function:
```lua
vim.diagnostic.config({
virtual_text = true,
signs = false,
underline = true,
update_in_insert = true,
severity_sort = false,
}[, namespace])
```
(or alternatively passed directly to `set()` or `show()`.)
When the `namespace` argument is `nil`, settings are set globally (i.e. for
*all* diagnostic namespaces). This is what user's will typically use for their
local configuration. Diagnostic producers can also set configuration options for
their specific namespace, although this is generally discouraged in order to
respect the user's global settings. All of the values in the table passed to
`vim.diagnostic.config()` are resolved in the same way that they are in
`on_publish_diagnostics`; that is, the value can be a boolean, a table, or
a function:
```lua
vim.diagnostic.config({
virtual_text = function(namespace, bufnr)
-- Only enable virtual text in buffer 3
return bufnr == 3
end,
})
```
## Misc Notes
* `vim.diagnostic` currently depends on `vim.lsp.util` for floating window
previews. I think this is okay for now, although ideally we'd want to decouple
these completely.
This generalizes diagnostic handling outside of just the scope of LSP.
LSP clients are now a specific case of a diagnostic producer, but the
diagnostic subsystem is decoupled from the LSP subsystem (or will be,
eventually).
