* feat(lsp)!: remove client-server handlers from vim.lsp.handlersLewis Russell2024-11-01
| | | | | | | | | | - Partition the handlers in vim.lsp.handlers as: - client to server response handlers (RCS) - server to client request handlers (RSC) - server to client notification handlers (NSC) Note use string indexes instead of protocol.methods for improved typing in LuaLS (tip: use hover on RCS, RSC or NSC).
* refactor(lsp): drop str_byteindex/str_utfindex wrappers #30915Tristan Knight2024-10-26
| | | | | * deprecate old signatures * move to new str_byteindex/str_utfindex signature * use single-underscore name (double-underscore is reserved for Lua itself)
* fix(lsp): fix cursor position after snippet expansion (#30659)Tomasz N2024-10-10
| | | | | | | | | | | | Problem: on `CompleteDone` cursor can jump to the end of line instead of the end of the completed word. Solution: remove only inserted word for snippet expansion instead of everything until eol. Fixes #30656 Co-authored-by: Mathias Fussenegger <f.mathias@zignar.net> Co-authored-by: Justin M. Keyes <justinkz@gmail.com>
* vim-patch:9.1.0771: completion attribute hl_group is confusingzeertzjq2024-10-10
| | | | | | | | | | | | | Problem: Currently completion attribute hl_group is combined with all items, which is redundant and confusing with kind_hlgroup Solution: Renamed to abbr_hlgroup and combine it only with the abbr item (glepnir). closes: vim/vim#15818 https://github.com/vim/vim/commit/0fe17f8ffbd2588ecd2bf42dced556897bc64f89 Co-authored-by: glepnir <glephunter@gmail.com>
* feat(lsp): improve LSP doc hover rendering #30695Justin M. Keyes2024-10-06
| | | | | | | | | | | | Problem: - Some servers like LuaLS add unwanted blank lines after multiline `@param` description. - List items do not wrap nicely. Solution: - When rendering the LSP doc hover, remove blank lines in each `@param` or `@return`. - But ensure exactly one empty line before each. - Set 'breakindent'.
* test: support upvalues in exec_luaLewis Russell2024-09-21

* feat(lsp): support hostname in rpc.connect #30238Tristan Knight2024-09-03
| | | | | | | | | | | | | | | Updated the `rpc.connect` function to support connecting to LSP servers using hostnames, not just IP addresses. This change includes updates to the documentation and additional test cases to verify the new functionality. - Modified `connect` function to resolve hostnames. - Updated documentation to reflect the change. - Added test case for connecting using hostname. Added a TCP echo server utility function to the LSP test suite. This server echoes the first message it receives and is used in tests to verify LSP server connections via both IP address and hostname. Refactored existing tests to use the new utility function.
* docs: misc #28970Justin M. Keyes2024-09-01

* fix(lsp): when prefix is non word add all result into matches (#30044)glepnir2024-08-30
| | | | | | | Problem: prefix can be a symbol like period, the fuzzy matching can't handle it correctly. Solution: when prefix is empty or a symbol add all lsp completion result into matches.
* feat(lsp): completion opts support custom item conversion (#30060)glepnir2024-08-22
| | | | | | | Problem: Some items of completion results include function signatures that can cause the pum to be very long when a function has many params, because pum scales with the longest word/abbr. Solution: add custom covert function that can customise abbr to remove params.
* test(lsp): refactor and tidyLewis Russell2024-08-11
| | | | | | | - Merge all the top level 'LSP' describe blocks - Refactor text edit tests - Fix typing errors - Add linebreaks between tests
* refactor(lsp): add test case for default diagnostic severityMathias Fussenegger2024-08-02
| | | | | | | | See https://github.com/microsoft/language-server-protocol/pull/1978 If the severity is not specified by the server, error should be used. This was already the case because it matches the vim.diagnostic default. This only adds a test case for it.
* fix(lsp): don't send foreign diagnostics to servers in buf.code_action (#29501)Mathias Fußenegger2024-08-01
| | | | | | | `buf.code_action` always included diagnostics on a given line from all clients. Servers should only receive diagnostics they published, and in the exact same format they sent it. Should fix https://github.com/neovim/neovim/issues/29500
* fix(lsp): prevent desync due to empty buffer (#29904)Jaehwang Jung2024-07-31
| | | | | | | | | | | | | | | Problem: Some language servers (e.g., rust-analyzer, texlab) are desynced when the user deletes the entire contents of the buffer. This is due to the discrepancy between how nvim computes diff and how nvim treats empty buffer. * diff: If the buffer became empty, then the diff includes the last line's eol. * empty buffer: Even if the buffer is empty, nvim regards it as having a single empty line with eol. Solution: Add special case for diff computation when the buffer becomes empty so that it does not include the eol of the last line.
* feat(lsp): lsp.completion support set deprecated (#29882)glepnir2024-07-31
| | | | | | Problem: CompletionItem in lsp spec mentioned the deprecated attribute Solution: when item has deprecated attribute set hl_group to DiagnosticDeprecated in complete function
* fix(lsp): inlay hints are rendered in the correct order (#29707)Amit Singh2024-07-17
| | | | | | | | | | | Problem: When there are multiple inlay hints present at the same position, they should be rendered in the order they are received in the response from LSP as per the LSP spec. Currently, this is not respected. Solution: Gather all hints for a given position, and then set it in a single extmark call instead of multiple set_extmark calls. This leads to fewer extmark calls and correct inlay hints being rendered.
* fix(lsp): fallback to `label` for completion items if all others are missing ↵Sebastian Lyng Johansen2024-07-02
| | | | (#29522)
* fix(lsp): pre-filter matches on label if filterText is missing (#29491)Mathias Fußenegger2024-06-27
| | | | | | | | | | | Although the built-in pum completion mechanism will filter anyway on the next input it is odd if the initial popup shows entries which don't match the current prefix. Using fuzzy match on the label/prefix is compatible with `completeopt+=fuzzy` and also doesn't seem to break postfix snippet cases Closes https://github.com/neovim/neovim/issues/29287
* fix(lsp): tune completion word extraction for decorated labels (#29331)Mathias Fußenegger2024-06-14
| | | | | | | | | | | | | | Problem: For snippets lsp.completion prefers the label if it is shorter than the insertText or textEdit to support postfix completion cases but clangd adds decoration characters to labels. E.g.: `•INT16_C(c)` Solution: Use parse_snippet on insertText/textEdit before checking if it is shorter than the label. Fixes https://github.com/neovim/neovim/issues/29301
* refactor(lsp): use metatable for buf_versions (#29304)Ilia Choly2024-06-14
| | | | | | This reduces the number of nil checks around buf_versions usage Test changes were lifted from 5c33815 Co-authored-by: Mathias Fussenegger <f.mathias@zignar.net>
* fix(lsp): revert buf_versions deprecation/replacement (#29217)Mathias Fußenegger2024-06-07
| | | | | | | | | * Revert "fix(lsp): account for changedtick version gap on modified reset (#29170)" This reverts commit 2e6d295f799c27372e5c0c44727fa613c81717fd. * Revert "refactor(lsp): replace util.buf_versions with changedtick (#28943)" This reverts commit 5c33815448e11b514678f39cecc74e68131d4628.

|
* fix(lsp): trim trailing whitespace from completion words (#29122)Mathias Fußenegger2024-06-02
| | | | | the `complete()` mechanism doesn't play nicely with trailing newlines or tabs. A newline causes it to insert a null character, showing up as `^@`.
* refactor(lsp): replace util.buf_versions with changedtick (#28943)Mathias Fußenegger2024-05-30
| | | | | | | `lsp.util.buf_versions` was already derived from changedtick (`on_lines` from `buf_attach` synced the version) As far as I can tell there is no need to keep track of the state in a separate table.
* feat(lsp): support postfix snippets in completionMathias Fussenegger2024-05-30
|
* feat(lsp): use fuzzy match on filterText instead of prefix matchMathias Fussenegger2024-05-30
| | | | | | | | The `complete()` mechanism matches completion candidates against the typed text, so strict pre-filtering isn't necessary. This is a first step towards supporting postfix snippets (like `items@insert` in luals)

* feat(lsp): inlay_hint.is_enabled({filter}) #28523Yi Ming2024-05-02
| | | vim.diagnostic.enable and vim.diagnostic.is_enabled() use the same pattern.
* feat(lsp): vim.lsp.inlay_hint.enable(nil) applies to all buffers #28543Yi Ming2024-05-02
| | | | | | | | | | | | | | | | | | Problem: Inlay hints `enable()` does not fully implement the `:help dev-lua` guidelines: Interface conventions ~ - When accepting a buffer id, etc., 0 means "current buffer", nil means "all buffers". Likewise for window id, tabpage id, etc. - Examples: |vim.lsp.codelens.clear()| |vim.diagnostic.enable()| Solution: Implement globally enabling inlay hints. * refactor(lsp): do not rely on `enable` to create autocmds * refactor(lsp): make `bufstates` a defaulttable * refactor(lsp): make `bufstate` inherit values from `globalstate` * feat(lsp): `vim.lsp.inlay_hints` now take effect on all buffers by default * test(lsp): add basic tests for enable inlay hints for all buffers * test(lsp): add test cases cover more than one buffer
* test: improve test conventionsdundargoc2024-04-23
| | | | | | | | | Specifically, functions that are run in the context of the test runner are put in module `test/testutil.lua` while the functions that are run in the context of the test session are put in `test/functional/testnvim.lua`. Closes https://github.com/neovim/neovim/issues/27004.
* feat(lua): enable(enable:boolean, filter:table) #28374Justin M. Keyes2024-04-18
| | | | | | | | | | | | | Problem: We need to establish a pattern for `enable()`. Solution: - First `enable()` parameter is always `enable:boolean`. - Update `vim.diagnostic.enable()` - Update `vim.lsp.inlay_hint.enable()`. - It was not released yet, so no deprecation is needed. But to help HEAD users, it will show an informative error. - vim.deprecate(): - Improve message when the "removal version" is a *current or older* version.

* test: reduce `exec_lua` callsdundargoc2024-04-04
| | | | | | | | | | | | | | | | | | | | | `exec_lua` makes code slighly harder to read, so it's beneficial to remove it in cases where it's possible or convenient. Not all `exec_lua` calls should be removed even if the test passes as it changes the semantics of the test even if it happens to pass. From https://github.com/neovim/neovim/pull/28155#discussion_r1548185779: "Note for tests like this, which fundamentally are about conversion, you end up changing what conversion you are testing. Even if the result happens to be same (as they often are, as we like the rules to be consistent if possible), you are now testing the RPC conversion rules instead of the vim script to in-process lua conversion rules." From https://github.com/neovim/neovim/pull/28155#discussion_r1548190152: "A test like this specifies that the cursor is valid immediately and not after a separate cycle of normal (or an other input-processing) mode."
* test(lsp): fix flaky basic_finish test again (#28041)zeertzjq2024-03-26
| | | | | | | Problem: LSP basic_finish test modified in #27899 is flaky again after #28030. Solution: Run on_setup() immediately after setup using a before_init callback.

* refactor(tests): all screen tests should use highlightsbfredl2024-03-23
| | | | | | | | | | | | | | | | | | | | | | | This is the first installment of a multi-PR series significantly refactoring how highlights are being specified. The end goal is to have a base set of 20 ish most common highlights, and then specific files only need to add more groups to that as needed. As a complicating factor, we also want to migrate to the new default color scheme eventually. But by sharing a base set, that future PR will hopefully be a lot smaller since a lot of tests will be migrated just simply by updating the base set in place. As a first step, fix the anti-pattern than Screen defaults to ignoring highlights. Highlights are integral part of the screen state, not something "extra" which we only test "sometimes". For now, we still allow opt-out via the intentionally ugly screen._default_attr_ids = nil The end goal is to get rid of all of these eventually (which will be easier as part of the color scheme migration)
* fix(lsp): add missing LSP semantic token highlight linksCaleb Marshall2024-03-16

* feat(lsp): deprecate severity_limitLewis Russell2024-02-08
| | | | | | | | | | | Problem: `vim.lsp.diagnostic.on_diagnostic` accepts an undocumented severity_limit option which is widely used. Solution: Deprecate it in favour of `{min = severity}` used in `vim.diagnostic`. Since this is undocumented, the schedule for removal is accelerated to 0.11.
