According to the specification `workspace/applyEdit` must be called with
`ApplyWorkspaceEditParams`.
So far the client just returned, which could lead to a misleading error
on the server side because `workspace/applyEdit` must respond with a
`ApplyWorkspaceEditResult`.
This adds an assertion to clarify that the server is violating the
specification.

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 })
```

Language servers can take some time to respond to the
`textDocument/hover` and `textDocument/signatureHelp` messages. During
that time, the user could have already moved to another buffer. The
popup was always shown in the current buffer, which could be a different
one than the buffer for which the request was sent.
This was particularly annoying when moving to a buffer with a `BufLeave`
autocmd, as that autocmd was triggered when the hover popup was shown
for the original buffer.
Ignoring the response from these 2 messages if they are for a buffer
that is not the current one leads to less noise. The popup will only be
shown for the buffer for which it was requested.
A more robust solution could involve cancelling the hover/signatureHelp
request if the buffer changes so the language server can free its
resources. It could be implemented in the future.
|
| |
|
|
| |
To illustrate a use-case this also changes `window/showMessageRequest`
to use `vim.ui.select`
|
| |
|
|
|
| |
- since cmd is a list, it runs directly ('no shell') and we shouldn't
escape.
- typo: shellerror -> shell_error

Without some form of feedback a user cannot easily tell if the server is
still computing the result (which can take a while in large projects),
or whether the server couldn't compute the rename result.

lists (#19213)
Currently LSP allows only using loclist or quickfix list window. I
normally prefer to review all quickfix items without opening quickfix
window. This fix allows passing `on_list` option which allows full
control what to do with list.
Here is example how to use it with quick fix list:
```lua
local function on_list(options)
vim.fn.setqflist({}, ' ', options)
vim.api.nvim_command('cfirst')
end
local bufopts = { noremap=true, silent=true, buffer=bufnr }
vim.keymap.set('n', '<leader>ad', function() vim.lsp.buf.declaration{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>d', function() vim.lsp.buf.definition{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>ai', function() vim.lsp.buf.implementation{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>at', function() vim.lsp.buf.type_definition{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>af', function() vim.lsp.buf.references(nil, {on_list=on_list}) end, bufopts)
```
If you prefer loclist do something like this:
```lua
local function on_list(options)
vim.fn.setloclist(0, {}, ' ', options)
vim.api.nvim_command('lopen')
end
```

Currently the `title`, `message` and `percentage` is stored for a
progress, but there is also an optional `cancellable` that comes in with
both the `WorkDoneProgressBegin` and also `WorkDoneProgressReport`. This
change also stores that value so that a plugin can access it when they
do a lookup in `client.messages`.

* feat(lsp)!: remove capabilities sanitization
Users must now access client.server_capabilities which matches the same
structure as the protocol.
https://microsoft.github.io/language-server-protocol/specification
client.resolved_capabilities is no longer used to gate capabilities, and
will be removed in a future release.

not working properly, which isn't the case.

The LSP progress handler would put non-progress messages (such as from
clangd or pyls; not part of the LSP spec) directly into
`client.messages`, while `vim.lsp.util.get_progress_messages()` would
try to fetch them from `client.messages.messages` instead (and come up
empty everytime). This would result in these messages never being
cleaned up by `get_progress_messages()`.
This commit fixes that by treating those messages like show-once
progress messages (by setting `done=true` immediately).

This gives quickfix/location lists created by handlers which use
'response_to_list' (textDocument/documentSymbols and workspace/symbol by
default) the ability to set a more useful list title. This commit gives
lists created for documentSymbols a title of the form:
Symbols in <filename>
and lists for workspace/symbol a title of the form:
Symbols matching '<query>'
These are more informative than a standard "Language Server" list title
and can help disambiguate results when users have multiple quickfix
lists that they cycle through with `:colder` and `:cnewer`.

This removes the "fallback" to utf-16 in many of our helper functions. We
should always explicitly pass these around when possible except in two
locations:
* generating params with help utilities called by buf.lua functions
* the buf.lua functions themselves
Anything that is called by the handler should be passed the offset encoding.

If clients receive a ContentModified error, it generally should not
show it in the UI for the end-user. Clients can resend the request if
they know how to do so.

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.

Solution:

https://github.com/neovim/neovim/commit/6c03601e3adb4c3c4d47f148df8df20401b88677.
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.

## 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).
