* Add optional second table argument to vim.json.decode which takes
a table 'luanil' which can include the 'object' and/or 'array' keys. These
options use luanil when converting NULL in json objects and arrays
respectively. The default behavior matches the original lua-cjson.
* Remove recursive_convert_NIL function from rpc.lua, use
vim.json.decode with luanil = { object = true } instead. This removes a hotpath
in the json deserialization pipeline by dropping keys with json NULL
values throughout the deserialized table.
- Refactor health.vim to discover lua healthcheck in the runtime
directories lua/**/health{/init}.lua
- Support healthchecks for lua submodules e.g :checkhealth vim.lsp and
also support wildcard "*" at the end for all submodules
:checkhealth vim*
- Refactor health.vim to use variable scope instead of output capturing
- Create health.lua module to wrap report functions and future
extensibility.
- Move away from searching just in the runtimepath, use
`nvim_get_runtime_file` due to #15632
Example:
Plugin linter in rtp can declare it's checkhealts in lua module
`lua/linter/health{/init}.lua` that returns a table with a method
"check" that when executed calls the report functions provided by the
builtin lua module require("health").
The plugin also has a submodule `/lua/linter/providers` in which it
defines `/lua/linter/providers/health{/init}.lua`
This plugin healthcheck can now be run by the ex command:
`:checkhealth linter linter.providers`
Also calling all submodules can be done by:
`:checkhealth linter*
And "linter" and "linter.provider" would be discovered when:
`:checkhealth`
Always make calls to `vim.diagnostic.set` call `vim.diagnostic.show`.
This creates an easier to reason about code path and is also less
surprising when users wish to override override `vim.diagnostic.show`
with custom behavior and `vim.diagnostic.set` is called with empty
diagnostics.
Functionally, the end result is the same: when `show` is called with an
empty diagnostics list, it just calls `hide` and then returns, which is
exactly what `reset` does right now.
N, W, S, E are all inclusive, i.e., always anchor to the exact corner of the
window (including border). This line may also need change in this case (change
0 to -1):
This is most consistent and easiest to reason about, especially with GUIs whose
border do not need to have width/height of 1/1 in cell units.
Fix#15789
Many vim.diagnostic functions expect the user to pass in a namespace id.
This PR allows the user to list active diagnostic namespaces:
```lua
:lua print(vim.inspect(vim.diagnostic.get_namespaces()))
{
[7] = {
name = "vim.lsp.client-1",
opts = {},
sign_group = "vim.diagnostic.vim.lsp.client-1"
}
}
```
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.
In vim.lsp.buf.references, the key vim.type_idx (which evaluates to a
boolean) was set to equal vim.types.dictionary. This resulted in a
boolean key in json which is not allowed by the json spec, and which
lua-cjson fails to serialize.
Rather than relying on the order in which signs are placed to dictate
the order in which they are displayed, explicitly set the priority of
the sign according to the severity of the diagnostic and the value of
severity_sort. If severity_sort is false or unset then all signs use the
same priority.
The `split()` VimL function trims empty items from the returned list by
default, so that, e.g.
split("\nhello\nworld\n\n", "\n")
returns
["hello", "world"]
The Lua implementation of vim.split does not do this. For example,
vim.split("\nhello\nworld\n\n", "\n")
returns
{'', 'hello', 'world', '', ''}
Add an optional parameter to the vim.split function that, when true,
trims these empty elements from the front and back of the returned
table. This is only possible for vim.split and not vim.gsplit; because
vim.gsplit is an iterator, there is no way for it to know if the current
item is the last non-empty item.
Note that in order to preserve backward compatibility, the parameter for
the Lua vim.split function is `trimempty`, while the VimL function uses
`keepempty` (i.e. they are opposites). This means there is a disconnect
between these two functions that may surprise users.

Solution:
This is a follow-up to the work done in
6c03601e3a.
There are valid situations where a `textDocument/codeAction` is returned
without a command, since a command in optional. For example from Metals,
the Scala language server when you get a code action to add a missing
import, it looks like this:
```json
Result: [
{
"title": "Import \u0027Instant\u0027 from package \u0027java.time\u0027",
"kind": "quickfix",
"diagnostics": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"severity": 1,
"source": "bloop",
"message": "not found: value Instant"
}
],
"edit": {
"changes": {
"file:///Users/ckipp/Documents/scala-workspace/sanity/src/main/scala/Thing.scala": [
{
"range": {
"start": {
"line": 6,
"character": 10
},
"end": {
"line": 6,
"character": 17
}
},
"newText": "Instant"
},
{
"range": {
"start": {
"line": 1,
"character": 0
},
"end": {
"line": 1,
"character": 0
}
},
"newText": "\nimport java.time.Instant\n"
}
]
}
}
}
]
```
This change just wraps the logic that grabs the command in a conditional
to skip it if there is no command.
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()
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.
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.
