`willSaveWaitUntil` allows servers to respond with text edits before
saving a document. That is used by some language servers to format a
document or apply quick fixes like removing unused imports.
Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
`:saveas newName` changes the name of an existing buffer.
Due to the buffer re-use it skips the lsp attach phase and immediately
sends a `didSave` notification to the server.
Servers get confused about this, because they expect a `didOpen`
notification first.
Closes https://github.com/neovim/neovim/issues/18688
Most LSP servers require the notification to correctly load the
settings and for those who don't it doesn't cause any harm.
So far this is done in lspconfig, but with the addition of vim.lsp.start
it should be part of core.
Cuts down typical run time for `plugin/lsp_spec.lua`
from 70 secs to 12 secs in ASAN CI build.
This happens in ASAN/EXIT_FREE builds where nvim waits 2000ms due to
unclosed handled. I wasn't able to pin-point the exact cause.
But these tests ran in nested context where two server/client pairs
were setup for no good reason. Moving these tests out so only one client
is being setup fixed the exit hang.
The current approach of using `on_attach` callbacks for configuring
buffers for LSP is suboptimal:
1. It does not use the standard Nvim interface for driving and hooking
into events (i.e. autocommands)
2. There is no way for "third parties" (e.g. plugins) to hook into the
event. This means that *all* buffer configuration must go into the
user-supplied on_attach callback. This also makes it impossible for
these configurations to be modular, since it all must happen in the
same place.
3. There is currently no way to do something when a client detaches from
a buffer (there is no `on_detach` callback).
The solution is to use the traditional method of event handling in Nvim:
autocommands. When a LSP client is attached to a buffer, fire a
`LspAttach`. Likewise, when a client detaches from a buffer fire a
`LspDetach` event.
This enables plugins to easily add LSP-specific configuration to buffers
as well as enabling users to make their own configurations more modular
(e.g. by creating multiple LspAttach autocommands that each do
something unique).
Implement filtering of actions based on the kind when passing the 'only'
parameter to code_action(). Action kinds are hierachical with a '.' as
the separator, and the filter thus allows, for example, both 'quickfix'
and 'quickfix.foo' when requestiong only 'quickfix'.
Fix https://github.com/neovim/neovim/pull/18221#issuecomment-1110179121
Adds filter and id options to filter the client to use for rename.
Similar to the recently added `format` function.
rename will use all matching clients one after another and can handle a
mix of prepareRename/rename support. Also ensures the right
`offset_encoding` is used for the `make_position_params` calls
This fixes issues where subsequent calls to vim.lsp.codelens.refresh()
would have no effect due to the buffer not getting cleared from the
active_refresh table.
Examples of how such scenarios would occur are:
- A textDocument/codeLens result yielded an error.
- The 'textDocument/codeLens' handler was overriden in such a way that
it no longer called vim.lsp.codelens.on_codelens().
Deprecates the existing `vim.lsp.buf.formatting` function.
With this, `vim.lsp.buf.format` will replace all three:
- vim.lsp.buf.formatting
- vim.lsp.buf.formatting_sync
- vim.lsp.buf.formatting_seq_sync
* 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.
BREAKING CHANGE
Co-authored-by: Mathias Fussenegger <f.mathias@zignar.net>
Implement two new options to vim.lsp.buf.code_action():
- filter (function): predicate taking an Action as input, and returning
a boolean.
- apply (boolean): when set to true, and there is just one remaining
action (after filtering), the action is applied without user query.
These options can, for example, be used to filter out, and automatically
apply, the action indicated by the server to be preferred:
vim.lsp.buf.code_action({
filter = function(action)
return action.isPreferred
end,
apply = true,
})
Fix#17514.
The use of 'softtabstop' to set tabSize was introduced in 5d5b068,
replacing 'tabstop'. If we look past the name tabSize and at the actual
purpose of the field, it's the indentation width used when formatting.
This corresponds to the Vim option 'shiftwidth', not 'softtabstop'.
The latter has the comparatively mundane purpose of controlling what
happens when you hit the tab key (and even this is incomplete, as it
fails to account for 'smarttab').
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.
omnisharp-roslyn can send negative values:
{
activeParameter = 0,
activeSignature = -1,
signatures = { {
documentation = "",
label = "TestEntity.TestEntity()",
parameters = {}
} }
}
In 3.16 of the specification `activeSignature` is defined as `uinteger`
and therefore negative values shouldn't be allowed, but within 3.15 it
was defined as `number` which makes me think we can be a bit lenient in
this case and handle them.
The expected behavior is quite clear:
The active signature. If omitted or the value lies outside the
range of `signatures` the value defaults to zero or is ignored if
the `SignatureHelp` has no signatures.
Fixes an error:
util.lua:1685: attempt to get length of local 'lines' (a nil value)
util.lua:1685: in function 'trim_empty_lines'
handlers.lua:334: in function 'textDocument/signatureHelp'
Part of the `pending_change` closure in the `changetracking.prepare` was
a bit confusing because it has access to `bufnr` and `uri` but it could
actually contain pending changes batched for multiple buffers.
(We accounted for that by grouping `pending_changes` by a `uri`, but
it's not obvious what's going on)
This commit changes the approach to do everything per buffer to avoid
any ambiguity.
It also brings the debounce/no-debounce a bit closer together: The
only difference is now whether a timer is used or if it is triggered
immediately
This allows the user to detach an active buffer from the language
client. If no clients remain attached to a buffer, the on_lines callback
is used to cancel nvim_buf_attach.
If a LSP server sent a workspace edit containing a rename the buffers
file name changed without the server receiving a close notification for
the old buffer and without the client properly re-attaching on the new
file.
This affected `Move` code-actions in nvim-jdtls, but also
`vim.lsp.buf.rename` on a class level.
* vim.ui.input is an overridable function that prompts for user input
* take an opts table and the `on_confirm` callback, see `:help vim.ui.input` for more details
* defaults to a wrapper around vim.fn.input(opts)
* switches the built-in client's rename handler to use vim.ui.input by default
Closes https://github.com/neovim/neovim/issues/15174
Instead of invoking handlers with unsupported methods, pre-compute which
clients support a given method and only notify the user if no clients
support the given method.
