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.
Closes#16624
Fixes two issues with aligning the start position and end position to
codepoints when calculating the start and end range.
When aligning the start position:
* use aligned byte index to calculate character index rather than
the unadjusted byte
When aligning the end position:
* do not adjust the end byte if it falls on a UTF-8 codepoint
* align byte to the first byte of the next codepoint rather than the
last byte of the current codepoint
* compute character character end range on the aligned byte index
This commit also adds additional test coverage, including multibyte operations
that previously failed before this commit.
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.
* use codeunits/points instead of byte ranges when applicable
* take into account different file formats when computing range and
sending text (dos, unix, and mac supported)
* add tests of incremental sync
* 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
Rather than treating virtual_text, signs, and underline specially,
introduce the concept of generic "handlers", of which those three are
simply the defaults bundled with Nvim. Handlers are called in
`vim.diagnostic.show()` and `vim.diagnostic.hide()` and are used to
handle how diagnostics are displayed.
The runtime file update
2286304cdb
added a `syn keyword` for `css`, which affects (via `html` and
`markdown` syntax files) the highlighting of `:checkhealth` output
(before, `ERROR:` was highlighted with `healthError`; now the colon is
no longer included).
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.
* fix(runtime/health): mitigate issues with duplicate healthchecks
Previously if a healthcheck was found as Lua and Vim it was executed
both times.
This new implementations prefers Lua, therefore if two are found It only
runs the Lua one, this way a plugin can mantain both implementations the
Lua one with the method `check()` and the autoload function `#check()`
(for none HEAD nvim versions).
**Note: This will require plugins to use `check()` as the function name,
since the autoload function that wraps the lua implementation won't be
called**
* docs(health): use spaces and don't overuse backtics
followup to #15259
Move away from providing completion with ExpandRTDir to ExpandGeneric
providing the function get_healthcheck_name which caches the results for
the current command line prompt.
It does the almost the same thing the Vim function 'get_healthcheck'
implemented in 'runtime/autoload/health.vim' does.
- Add tests for lua healthchecks (failure, success and submodules).
- Reword some of the test naming for improved logs readability.
- Modify render test to accomodate the changes of the health autoload function.
- Add test for :checkhealth completion of Lua healtchecks.
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
* 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 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.
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.
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).
More discussion at [1].
[1]: https://github.com/neovim/neovim/pull/15585
Previously, the handler signature was:
function(err, method, params, client_id, bufnr, config)
In order to better support external plugins that wish to extend the
protocol, there is other information which would be advantageous to
forward to the client, such as the original params of the request that
generated the callback.
In order to do this, we would need to break symmetry of the handlers, to
add an additional "params" as the 7th argument.
Instead, this PR changes the signature of the handlers to:
function(err, result, ctx, config)
where ctx (the context) includes params, client_id, and bufnr. This also leaves
flexibility for future use-cases.
BREAKING_CHANGE: changes the signature of the built-in client handlers, requiring
updating handler calls
Add two new methods to allow diagnostics to be disabled (and re-enabled)
in the current buffer. When diagnostics are disabled they are simply not
displayed to the user, but they are still sent by the server and
processed by the client.
Disabling diagnostics can be helpful in a number of scenarios. For
example, if one is working on a buffer with an overwhelming amount of
diagnostic warnings it can be helpful to simply disable diagnostics
without disabling the LSP client entirely. This also allows users more
flexibility on when and how they may want diagnostic information to be
displayed. For example, some users may not want to display diagnostic
information until after the buffer is first written.
This commit prevents two things regarding the tagstack and jumping to
locations:
- Pushing the same item twice in a row
- Pushing an item where the destination is the same as the source
Both prevent having to press CTRL-T additional times just to pop items
that don't make the cursor move.
There were a couple of reports of "Buffer X newer than edits" problems.
We first assumed that it is incorrect for a server to send 0 as a
version - and stated that they should send a `null` instead, given that
in the specification the `textDocument` of a `TextDocumentEdit` is a
`OptionalVersionedTextDocumentIdentifier`.
But it turns out that this was a change in 3.16, and in 3.15 and earlier
versions of the specification it was a `VersionedTextDocumentIdentifier`
and language servers didn't have a better option than sending `0` if
they don't keep track of the version numbers.
So this changes the version check to always accept `0` values.

before, calling vim.schedule() from inside an event would execute
the scheduled callback immediately after this event without
checking for user input in between. Break event processing
whenever user input or an interrupt is available.
* lsp: client stop cleanups
* Add diagnostic clearing to client.stop() method used by nvim-lspconfig
* Clear diagnostic cache to prevent stale diagnostics on client restart
* lsp: Add test for vim.lsp.diagnostic.reset
The `workspace/configuration` handler could fail with the following
error if `config.settings` is nil:
runtime/lua/vim/lsp/util.lua:1432: attempt to index local 'settings' (a nil value)"
This ensures that `config.settings` is always initialized to an empty
table.
* lsp: Remove duplicate `diagnostics` fallback in diagnostic.display
* lsp: Expose all diagnostics
Before the changes in #12655 it was possible to retrieve all diagnostics
via `vim.lsp.util.diagnostics_by_buf`.
This adds a `diagnostic.get_all()` to enable users to retrieve all
diagnostics.
Use cases for that could include loading all diagnostics into the
quickfix list, or to build an enhanced goto_next that can move across
buffers.
Breaking Changes:
- Deprecated all `vim.lsp.util.{*diagnostics*}()` functions.
- Instead, all functions must be found in vim.lsp.diagnostic
- For now, they issue a warning ONCE per neovim session. In a
"little while" we will remove them completely.
- `vim.lsp.callbacks` has moved to `vim.lsp.handlers`.
- For a "little while" we will just redirect `vim.lsp.callbacks` to
`vim.lsp.handlers`. However, we will remove this at some point, so
it is recommended that you change all of your references to
`callbacks` into `handlers`.
- This also means that for functions like |vim.lsp.start_client()|
and similar, keyword style arguments have moved from "callbacks"
to "handlers". Once again, these are currently being forward, but
will cease to be forwarded in a "little while".
- Changed the highlight groups for LspDiagnostic highlight as they were
inconsistently named.
- For more information, see |lsp-highlight-diagnostics|
- Changed the sign group names as well, to be consistent with
|lsp-highlight-diagnostics|
General Enhancements:
- Rewrote much of the getting started help document for lsp. It also
provides a much nicer configuration strategy, so as to not recommend
globally overwriting builtin neovim mappings.
LSP Enhancements:
- Introduced the concept of |lsp-handlers| which will allow much better
customization for users without having to copy & paste entire files /
functions / etc.
Diagnostic Enhancements:
- "goto next diagnostic" |vim.lsp.diagnostic.goto_next()|
- "goto prev diagnostic" |vim.lsp.diagnostic.goto_prev()|
- For each of the gotos, auto open diagnostics is available as a
configuration option
- Configurable diagnostic handling:
- See |vim.lsp.diagnostic.on_publish_diagnostics()|
- Delay display until after insert mode
- Configure signs
- Configure virtual text
- Configure underline
- Set the location list with the buffers diagnostics.
- See |vim.lsp.diagnostic.set_loclist()|
- Better performance for getting counts and line diagnostics
- They are now cached on save, to enhance lookups.
- Particularly useful for checking in statusline, etc.
- Actual testing :)
- See ./test/functional/plugin/lsp/diagnostic_spec.lua
- Added `guisp` for underline highlighting
NOTE: "a little while" means enough time to feel like most plugins and
plugin authors have had a chance to refactor their code to use the
updated calls. Then we will remove them completely. There is no need to
keep them, because we don't have any released version of neovim that
exposes these APIs. I'm trying to be nice to people following HEAD :)

Refactors how required capabilities are detected and validated, and make
sure requests are only sent to clients that support it (and only fail if
no clients support the provided method).
The validation happens at the buf_request level, because we assume that
if someone is sending the request directly through the client, they know
what they're doing. Also, let unknown methods go through.
This is extracted from #12518 and closes#12755.

According to the LSP spec[1], multiple edits can have the same starting
position, and if that is the case, they should be applied in the order
as they come in the array.
The implementation uses a reverse sort to not interfere with non applied
edits, but failed to take into account the spec.

If the LSP sends an end line that is larger than what nvim considers to be the

This commit creates 4 new highlight groups:
- LspDiagnosticsErrorSign
- LspDiagnosticsWarningSign
- LspDiagnosticsInformationSign
- LspDiagnosticsHintSign
These highlight groups are linked to their corresponding LspDiagnostics
highlight groups by default.
This lets users choose a different color for their sign columns and
virtualtext diagnostics.
Expose `vim.lsp.buf.diagnostics_by_buf`
This makes it easier to customize the diagnostics behavior. For example
to defer the update they can override the
`textDocument/publishDiagnostics` callback to only call
`buf_diagnostics_save_positions` and then defer the other actions to a
autocmd event.
- os.exit(1) is too generic, since code 1 may be caused by Nvim exiting

Reduce API surface. We don't need so many variations of functions. Too
many functions means verbose, largely redundant documentation, tests,
and cognitive burden.

- Send indent options to rangeFormatting and formatting.
- Remove references to vim bindings and filetype from lsp.txt
- Add more examples to docs.
- Add before_init to allow changing initialize_params.
Mainly configuration and RPC infrastructure can be considered "done". Specific requests and their callbacks will be improved later (and also served by plugins). There are also some TODO:s for the client itself, like incremental updates.

It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.
Doing clear() multiple times in quick succession provokes the
`exit_event` race described in #8813.
- Avoid it by removing unnecessary reset() call.
- Replace unnecessary nested describe() blocks with it() blocks.

luassert uses 3 by default, which is often not enough.
Instead of documenting how to increase it, let's use a more fitting
(sane) default of 100 levels.
The call to plugin_helpers.reset() is redundant with the clear() call
above it. Probably just a copy-paste mistake.
Avoids exit_event race #8813.

Give embeders a chance to set up nvim, by processing a request before
startup. This allows an external UI to show messages and prompts from
--cmd and buffer loading (e.g. swap files)
Lua (not LuaJIT) complains about the "^[[" strings inside the expect,
since it sees them as nested quotes. Change the quoting to [=[ ]=] to
avoid the issue.
Use unique filenames to avoid test conflicts.
Use read_file() instead of io.popen(), to ensures the file is closed.
Use helpers.rmdir(), it is far more robust than lfs.

`:syntax keyword` is affected by 'iskeyword'. When we aligned
'iskeyword' to that of filetype=help, colon (:) is now included.
Simplest way to deal with this is to include colon (:) in the `:syntax

Also:
- change "SUGGESTIONS" mouthful to "ADVICE"
- change "SUCCESS" to "OK"

- Vim "unix default" of 'noshowcmd' is serving few users. And it's

-NaN doesn't exist in the IEEE 754 spec, it is a hardware-specific detail
