v18.0.2

18.0.2 - 2024-10-18

Breaking changes:

• The -v parameter is now ignored because, it pollutes the *debug* buffer since version 18.0.0.
  Use the lsp_debug option instead. It's only meant to be set temporarily, for debugging.
  For the case where kak-lsp is started outside the editor, an equivalent --debug command line flag has been added.

Fixes:

• Fix startup error on HTML files.
• Fix a regression in lsp-workspace-symbol{,-incr} commands.
• Fix crash due to a regression in lsp-highlight-references.
• Demote a number of logs to keep the *debug* buffer clean. Only errors, warnings and occasional info logs should be shown.
• The info box shown by lsp-show-message-{error,warning,info} is no longer created in the toolsclient but in the most recently used client.
• Fix missing error messages when LSP commands are run from either a scratch buffer or a buffer where the server is not installed.

Additions

• Further reduce the number of shell calls caused by hooks, in addition to the work done on this in version 18.0.0.
• When crashing via a Rust panic, the process is now aborted and creates a coredump.
  Also, crashes are now shown in an info box.

v18.0.1

18.0.1 - 2024-10-14

Fix error parsing a legacy kak-lsp.toml that doesn't have a language_ids section.

v18.0.0

18.0.0 - 2024-10-13

The kak-lsp.toml config file has been deprecated, as have been lsp_config, KAK_LSP_PROJECT_ROOT_* and KAK_LSP_FORCE_PROJECT_ROOT as well as commandline flags --config, --log and --timeout.
This is in favor of new Kakoune options lsp_servers, lsp_language_id, lsp_semantic_tokens, lsp_timeout, lsp_snippet_support and lsp_file_watch_support.
In particular, the lsp_servers option makes it easier to

1. override servers only for specific filetypes, and
2. set server config dynamically (based on project etc.) via Kakoune commands and hooks.

For backwards compatibility, the new options are ignored if a kak-lsp.toml exists in the user's config directory (or is provided via --config).
By default, lsp_servers and lsp_language_id are populated via the hooks in the lsp-filetype-.* groups, feel free to remove them.
See the documentation of the respective options for details.
Thanks to Tobias Pisani for designing this config rework.

Breaking changes:

• The --session argument used to allow using a single kakoune-lsp server from multiple Kakoune sessions.
  This feature has been removed to allow supporting rename-session better;
  it may be added back if we find a need for it.
  The --session argument is now ignored, except when kak-lsp is started outside the editor.
  This means that you probably don't need to override the lsp_cmd option anymore.
  Additionally, rename-session no longer breaks kakoune-lsp by invalidating the --session argument.
• lsp-stop-on-exit-disable and lsp-stop-on-exit-enable no longer have an effect.
  Instead, the kakoune-lsp server will always stop running as soon as its associated Kakoune session exits.
• The default server timeout has been increased from 1800 seconds (30 minutes) to 18000 seconds (5 hours),
  to avoid potential delays from frequent restarts.

Additions:

• Log messages are now written to the *debug* buffer.
• New option lsp_debug to control log verbosity without restarting kak-lsp.
• New command lsp-restart.
• The --kakoune argument is no longer needed and has been deprecated.
  This simplifies the minimal configuration to eval %sh{kak-lsp}; lsp-enable.
• If the server supports LSP workspaceFolders, a single language server
  instance will be reused for all projects in a Kakoune session.
  The file where the language server was originally started from determines the (only) workspaceFolder we send to the language server.
• In language server definitions, the command field is now optional and defaults to the name of the language server.
• New faces DiagnosticTagDeprecated and DiagnosticTagUnnecessary for the LSP's diagnostic tags.

Fixes:

• On rename-session, the kakoune-lsp server for the old session will be shut down.
  This only works with Kakoune version >= v2024.05.09.
• lsp-* commands that require lsp-enable/lsp-enable-window now fail more explicitly.
• Fix a crash when requesting code actions from rust-analyzer.
• Fix a crash when running Rust unit tests via rust-analyzer's lsp-code-lens.
• lsp-goto-document-symbol now uses qualified names, to make sure that it shows all symbols in the current buffer.

v17.1.2

17.1.2 - 2024-08-17

Additions:

• Experimental LSP client capabilities can now be enabled via kak-lsp.toml.

Fixes:

• Fix crash on multiple language servers when one server doesn't support code actions.
• For consistency with our root_path project detection mechanism, the default config for Julia no longer supports the JULIA_PROJECT environment variable nor falls back on the global Julia environment.
• Fix build on Rust 1.80.

v17.1.1

17.1.1 - 2024-06-27

Additions:

• Default configuration for Svelte via svelte-language-server.
• The language server stderr is logged eagerly instead of only after server exit; (useful for when servers like rust-analyzer crash).
• Support dynamic for registration semantic tokens via textDocument/semanticTokens.
• lsp-code-actions has learned to filter by code action kind.
  This should obsolete the lsp-code-action command which has been hidden and deprecated.
• lsp-code-actions learned the -auto-single switch to instantly run if there is only one matching code action.
• The default config now enables inlay hints also for recent version of Scala Metals.

Fixes:

• Fixed a case where a legacy kak-lsp.toml specifying the same server for multiple languages would drop all but one language.
• Some hover info had extra trailing whitespace, which is now trimmed properly.
• Hover info containing ASCII-art tables as popular in some flavors of Markdown is now rendered properly.

v17.0.1

17.0.1 - 2024-04-06

Small patch release to fix a regression.

Fixes:

• Fix startup error when both lsp.kak and Kakoune's jump.kak are autoloaded.

v17.0.0

17.0.0 - 2024-04-04

Breaking changes:

• New default server for Nix, nil, replacing rnix-lsp.
• The gopls usePlaceholders setting now defaults to true in the default config, make sure to either add a mapping for lsp-snippets-select-next-placeholders or disable snippets.
• gopls default config has been changed so inlay (type) hints require no gopls-specific knobs to turn on. As with other servers, inlay hints are only requested when lsp-inlay-hints-enabled is used.
• The default config for HTML/CSS/JSON has been updated to use vscode-{html,css,json}-language-server as server command instead of vscode-{html,css,json}-languageserver.
• Support for watching files (workspace/didChangeWatchedFiles) is now disabled by default to avoid performance problems.
• Inlay code lenses (used by OCaml and Haskell language servers) are now shown after the referenced line. This requires Kakoune version >= 2024.
• lsp-auto-hover-enable no longer takes an argument; that functionality has been moved to lsp-auto-hover-buffer-enable, and it no longer magically spawns a client.
• Removed lsp-connect experimental command.

Additions:

• New commands jump-{next,previous} (which have also been added to Kakoune) replace and deprecate lsp-{next,previous}.
• lsp-document-symbol no longer renders the same filename in every single line. Commands like jump-next and <ret> still work as before.
• New option lsp_hover_max_info_lines replaces and deprecates lsp_hover_max_lines which now defaults to -1 which means lsp_hover_max_info_lines is used to control lines of information in the hover box.
• New option lsp_hover_max_diagnostic_lines to limit the lines for diagnostics in the hover box.

Fixes:

• Fix gopls code actions like "Extract function".
• Various improvements to compatibility with old Kakoune.

v16.0.0

16.0.0 - 2024-02-20

Both the kak-lsp project and GitHub organization have been renamed to kakoune-lsp. The binary and config file paths are unchanged. Distributors are encouraged to update the package name.

Breaking changes:

• kakoune-lsp now requires Kakoune version >= v2022.10.31 for commands that use a menu, like code actions.

Additions:

• The modeline shows breadcrumbs like somemodule > someclass > somefunction to indicate the symbol around the main cursor.
• lsp-document-symbols now renders symbols in a tree.
• lsp_auto_show_code_actions (which renders a lightbulb in the modeline) now defaults to true.
• lsp-code-lens can now run the test at cursor with rust-analyzer.

Fixes:

• lsp-inlay-diagnostics no longer jump around when the cursor is moved over the diagnostics. To use this feature, use Kakoune version >= 2024 (not yet release, consider building from source).
• When LSP integration is enabled, then disabled and enabled again, the KakEnd hook failed to ask the server to exit, which has been fixed.
• lsp-auto-hover-enable now only re-renders hover info when the main selection changes. This means that :info is no longer shadowed immediately by auto hover.
• Completion snippets (accessed via lsp-snippets-select-next-placeholders) can now be nested, making it possible to cycle through the arguments of nested function calls.
• In some cases, selecting completions provided by rust-analyzer would labels with extra characters (like self.some_method(…)) which has been fixed.
• completionItem.additionalTextEdits are now applied also when the server does not support completionItem/resolve.
• Snippet metacharacters are now properly escaped, removing spurious backslashes from inserted completions.

v15.0.1

15.0.1 - 2023-12-11

Additions:

• Default configuration for Markdown via marksman.
• Default configuration for Java via jdtls.

Fixes:

• Fix regression in "lsp-show-message-error" and friends.

v15.0.0

15.0.0 - 2023-11-15

Additions:

• Support multiple language servers per filetype (#17).
• The kak-lsp.toml format for specifying language servers has changed. The old format is still supported (#686).
• lsp-goto-document-symbol learned to show a preview of the jump target.
• Default configuration for PureScript and Scala.

Fixes:

• A regression broke resolving completion item documentation when cycling through completion candidates, which has been fixed (#674).
• New command lsp-declaration, implementing textDocument/declaration.
