diagnostic_lines() returns a table, so make the early exit condition an
empty table rather than 'nil'. This way, functions that use the input
from diagnostic_lines don't have to do a bunch of defensive nil checking
and can always assume they're operating on a table.
This function isn't compatible with including diagnostic sources when
"source" is "if_many" since it only has access to diagnostics for a
single line. Rather than having an inconsistent or incomplete interface,
make this function private. It is still exported as part of the module
for backward compatibility with vim.lsp.diagnostics, but it can
eventually be made into a local function.
* preserve fields from LSP diagnostics via adding a user_data table to the diagnostic, which can hold arbitrary data in addition to the lsp diagnostic information.
This fixes the handler signature and also prevents n+1 requests firing
if there are multiple clients.
(The first `prepareCallHierarchy` handler is called once per client,
each invocation used `buf_request` to make more requests using *all*
clients)
This is mostly motivated by https://github.com/neovim/neovim/issues/12326
Client side commands might need to access the original request
parameters.
Currently this is already possible by using closures with
`vim.lsp.buf_request`, but the global handlers so far couldn't access
the request parameters.
Some parts of LSP need to use cached diagnostics as sent from the LSP
server unmodified. Rather than fixing invalid line numbers when
diagnostics are first set, fix them when they are displayed to the user
(e.g. in show() or one of the get_next/get_prev family of functions).
* feat(diagnostic): add vim.diagnostic.match()
Provide vim.diagnostic.match() to generate a diagnostic from a string and
a Lua pattern.
* feat(diagnostic): add tolist() and fromlist()
Problem: Cannot get composing characters from the screen.
Solution: Add screenchars() and screenstring(). (partly by Ozaki Kiichi,

When vim.diagnostic.config() is called, the decorations for diagnostics
are re-displayed to use the new configuration. This should only be done
for loaded buffers.
Now remove the addition of "start/*" packages in 'packpath' as
explicit items in 'runtimepath'. This avoids 'runtimepath' from becoming
very long when using a lot of plugins as packages.
To get the effective search path as a list, use |nvim_list_runtime_paths()|
When severity_sort is true, higher severities should be displayed before
lower severities (e.g. ERROR is displayed over WARN).
Also improved the test case for this.
The recursive implementation of vim.lsp.diagnostic.get() applied
`diagnostic_vim_to_lsp` twice, and the second time gave wrong
results because of the unexpected format.

These links were actually defined backwards: the highlight groups
actually being used for display are the new "Diagnostic*" groups, so
linking the old "LspDiagnostics*" groups to these does absolutely
nothing, since there is nothing actually being highlighted with the
LspDiagnostics* groups.
These links were made in an attempt to preserve backward compatibility
with existing colorschemes. We could reverse the links to maintain this
preservation, but then that disallows us from actually defining default
values for the new highlight groups.
Instead, just remove the links and be done with the old LspDiagnostics*
highlight groups.
This is not technically a breaking change: the breaking change already
happened in #15585, but this PR just makes that explicit.
## 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.
Port VimL's Blob type - vim-patch:8.1.{0735,0736,0738,0741,0742,0755,0756,0757,0765,0793,0797,0798,0802,1022,1023,1671},8.2.{0121,0184,0404,0521,0829,1473,1866,2712}
Problem:
`buftype=help` occasionally propagates from help to man buffer. As a result the
next time you open help it opens in the man window, replacing the manpage.
Test case:
nvim -u NORC
:Man man
:set bt? " should print `buftype=nofile`
:help
<C-W><C-W><C-W>c " go back to :Man window and close it
:help " focus help window
:Man man " open window with manpage again
:set bt? " prints `buftype=help`
Solution:
- call s:set_options()
- man#read_page() (called by autocmd BufReadCmd man://*) should already do
this. But BufReadCmd doesn't fire for already-existing man:// buffers.
Fix#15650
Also includes some small relevant nearby non-Blob changes and typo
fixes.
Changes are included from:
- v8.1.0815
- v8.1.0846
- v8.1.1084

Note that it is not possible for msgpack_unpack_next() and
msgpack_unpacker_next() to return MSGPACK_UNPACK_EXTRA_BYTES, so it
should be fine to abort() on that.
Lua 5.1 doesn't support string hex escapes (\xXX) like VimL does (though
LuaJIT does), so convert them to decimal escapes (\DDD) in tests.
These were issues that I found while porting that I fixed upstream. :^)
Very little of the patch can be exactly ported as we're a bit behind on
dependant patches (we also can't use the exact :for emsg, as we don't
support iterating over Strings yet), so just translate the fixes as best
as we can for now.
Include latest relevant doc changes from:
- v8.1.0815
- v8.2.2658
Problem: Items in a list given to :const can still be modified.
Solution: Work like ":lockvar! name" but don't lock referenced items.
Make locking a blob work.
