* fix(lsp): send didOpen if name changes on write (#19583)Mathias Fußenegger2022-08-01
| | | | | | | | | `: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
* refactor(lsp): use autocmd api (#19407)ii142022-07-17

* fix(lsp): small bugs in snippet-parser #18998L3MON4D32022-06-29
| | | | | | | | | This fixes the following bugs: `${1:else_text}` -> format with if_text: "else_text" `${1:-else_text}` -> format with if_text: "else_text" `${1:}` in `format` (eg. empty else_text) -> error. `${1:}` (eg. empty placeholder) -> error. Thanks hrsh7th :)
* test(report): formatting, drop dumplog()Justin M. Keyes2022-06-15
| | | | | Don't need to dumplog() on each failed test because we now have test-ids that associate log messages with tests.
* fix(lsp): fix multi client handling in code action (#18869)Mathias Fußenegger2022-06-05

* feat(lsp): send didChangeConfiguration after init (#18847)Mathias Fußenegger2022-06-03
| | | | | | | 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.
* fix(checkhealth): skip vim.health #18816Javier Lopez2022-06-01
| | | | | | | | | | | | | | | | | | Problem: https://github.com/neovim/neovim/pull/18720#issuecomment-1142614996 The vim.health module is detected as a healthcheck, which produces spurious errors: vim: require("vim.health").check() ======================================================================== - ERROR: Failed to run healthcheck for "vim" plugin. Exception: function health#check, line 20 Vim(eval):E5108: Error executing lua [string "luaeval()"]:1: attempt to call field 'check' (a nil value) stack traceback: [string "luaeval()"]:1: in main chunk Solution: Skip vim.health when discovering healthchecks.
* fix(ci): remove 2000ms blocking wait in many plugin/lsp_spec.lua testsbfredl2022-05-22
| | | | | | | | | | | 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.
* feat(lsp): add LspAttach and LspDetach autocommandsGregory Anders2022-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | 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).
* fix(man.vim): q in "$MANPAGER mode" does not quit #18443Arsham Shirvani2022-05-13
| | | | | | | | | | | | | | | | | Problem: q in "$MANPAGER mode" does not quit Nvim. This is because ftplugin/man.vim creates its own mapping: nnoremap <silent> <buffer> <nowait> q :lclose<CR><C-W>c which overrides the one set by the autoload file when using :Man! ("$MANPAGER mode") Solution: Set b:pager during "$MANPAGER mode" so that ftplugin/man.vim can set the mapping correctly.

* fix(lsp): perform client side filtering of code actions (#18392)Fredrik Ekre2022-05-12
| | | | | | | | 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
* fix(lsp): fix rename capability checks and multi client support (#18441)Mathias Fußenegger2022-05-05
| | | | | | | | 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
* fix(lsp): make sure to always reset active codelens refreshes (#18331)William Boman2022-05-05
| | | | | | | | | | | 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().

* feat(lsp): add async option to vim.lsp.buf.format (#18322)Mathias Fußenegger2022-04-30
| | | | | | | | 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

* chore(lsp): remove capabilities sanitization (#17814)Michael Lingelbach2022-04-30
| | | | | | | | | | | | | | | | * 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.

* feat(lsp): options to filter and auto-apply code actions (#18221)Fredrik Ekre2022-04-30
| | | | | | | | | | | | | | | | | | | 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.
* fix(lsp): fix unnecessary buffers being added on empty diagnostics (#18275)ii142022-04-26
| | | | | Some language servers send empty `textDocument/publishDiagnostics` messages after indexing the project with URIs corresponding to unopened buffers. This commit guards against opening buffers corresponding to empty diagnostics.

* fix(lsp): set tabSize from 'shiftwidth', not 'softtabstop' (#17787)Tim Pope2022-03-20
| | | | | | | | | 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').

* fix(lsp): strictly enforce passing offset encoding (#17049)Michael Lingelbach2022-01-13
| | | | | | | | | | 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.
* fix(lsp): handle negative activeSignature in signatureHelp (#17064)Mathias Fußenegger2022-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'

* refactor(lsp): debounce timer per buf and unify with non-debounce (#17016)Mathias Fußenegger2022-01-11
| | | | | | | | | | | | | | | | 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
* feat(lsp): enable default debounce of 150 ms (#16908)Michael Lingelbach2022-01-05

* feat(lsp): add buf_detach_client (#16250)Michael Lingelbach2021-12-21
| | | | | 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.

* fix(lsp): correctly align start and end range to codepoints during ↵Rishikesh Vaishnav2021-12-17
| | | | | | | | | | | | | | | | | | | | | incremental sync (#16670) 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.

* fix(lsp): ensure buffers are re-attached on rename (#16266)Mathias Fußenegger2021-11-14
| | | | | | | | | 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.
* fix(lsp): rewrite incremental sync (#16252)Michael Lingelbach2021-11-09

* feat(ui): add vim.ui.input and use in lsp rename (#15959)Sebastian Lyng Johansen2021-11-07
| | | | | | * 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

* refactor(diagnostic): make display handlers generic (#16137)Gregory Anders2021-10-29
| | | | | | | 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.
