In the `test_rpc_server` procedure, both `on_setup` and `on_init`
callbacks can run concurrently in some scenarios. This caused some CI
failures in tests for the LSP set_defaults feature.
This commit attempts to fix this by merging those two callbacks in the
impacted tests.

Problem:
When LSP client renames a directory, opened buffers in the edfitor are not
renamed or closed. Then `:wall` shows errors.
https://github.com/neovim/neovim/blob/master/runtime/lua/vim/lsp/util.lua#L776
works correctly if you try to rename a single file, but doesn't delete old
buffers with `old_fname` is a dir.
Solution:
Update the logic in runtime/lua/vim/lsp/util.lua:rename()
Fixes#22617
Sets `NVIM_APPNAME` for the lsp server instances and also for the
`exec_lua` environment to ensure local user config doesn't interfere
with the test cases.
My local `ftplugin/xml.lua` broke the LSP test cases about setting
`omnifunc` defaults.
Problem:
Some built-in ftplugins set omnifunc/tagfunc/formatexpr which causes
lsp.lua:set_defaults() to skip setup of defaults for those filetypes.
For example the C++ ftplugin has:
omnifunc=ccomplete#Complete
Last set from /usr/share/nvim/runtime/ftplugin/c.vim line 30
so the changes done in #95c65a6b221fe6e1cf91e8322e7d7571dc511a71
will always be skipped for C++ files.
Solution:
Overwrite omnifunc/tagfunc/formatexpr options that were set by stock
ftplugin.
Fixes#21001
`vim.lsp.buf.format()` silently did nothing if no servers supported
`textDocument/rangeFormatting` when formatting with a range.
Issue found by `@hwrd:matrix.org` in the Matrix chat.
`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.
