Changelog#

Unreleased 9.0.1#

  • Add support for earthlyls
  • Add support for GNAT Project (gpr-mode, gpr-ts-mode).
  • Add SQL support
  • Add support for Meson build system. (meson-mode).
  • Add support for go to definition for external files (.dll) in CSharp projects for OmniSharp server.
  • Added a new optional :action-filter argument when defining LSP clients that allows code action requests to be modified before they are sent to the server. This is used by the Haskell language server client to work around an lsp-mode parsing quirk that incorrectly sends null values instead of false in code action requests.
  • Add support for C# via the Roslyn language server.
  • Add basic support for pull diagnostics requests.
  • Add lsp-flush-delayed-changes-before-next-message customization point to enforce throttling document change notifications.
  • Add lsp-sql-show-tables command.
  • Fix bug in rust-analyzer.check.features configuration via lsp-rust-checkonsave-features Emacs setting: we were defaulting to [], but rust-analyzer defaults to inheriting the value from rust-analyzer.cargo.features. The bug resulted in code hidden behind features not getting type checked when those features were enabled by setting rust-analyzer.cargo.features via the lsp-rust-features Emacs setting.
  • Change ruff-lsp to ruff for python lsp client. All ruff-lsp customizable variable change to ruff. Lsp server command now is ["ruff" "server"] instead of ["ruff-lsp"].
  • Add futhark support
  • Optimize overlay creation by checking window visibility first
  • Replace the per-interface (INTERFACE ...) pcase forms with a single, unified (lsp-interface INTERFACE ...) form. The per-interface forms are no longer generated. This is a breaking change. (See #4430.)

Support for new languages/language servers:#

New logging options#

  • lsp-mode now logs to buffer *lsp-log*, instead of *Messages*. This can be controlled with the variable lsp-log-max (Thanks to Thomas Fini Hansen).
  • If lsp-print-performance is non-nil, lsp-mode will log a corresponding performance trace to *lsp-log* for every message to and from the server.
  • The variable lsp-print-io, when non-nil will cause lsp-mode to log all messages to and from the server to a unique *lsp-io* buffer for every project root. These logs can be saved to a file and viewed using the LSP Inspector.

LSP Methods#

  • Add support for textDocument/prepareRename. If supported by the language server, all renaming operations will be tested for validity.
  • Add support for file watches.

  • Changed flymake to report the errors immediately after they arrive instead of waiting flymake to call lsp-mode.
  • Add debounce when server does not support incremental updates.
  • Add hook lsp-after-uninitialized-hook, which stores the list of functions called after a language server has been uninitialized.
  • Add variable lsp-symbol-highlighting-skip-current, which lets the user skip the current symbol when a given symbol is being highlighted.
  • Add variable lsp-enabled-clients, which lets users set which defined clients are allowed to be used.
  • Support multiple signatures while displaying eldoc text. Add variable lsp-signature-render-all, which when non-nil forces lsp-mode to only show the current active signature.

  • Added flymake integration.
  • lsp automatically enables and configures company-lsp, lsp-ui, yasnippet, or flymake if they are present so no additional configuration is needed except installing the packages. That behavior could be disabled by setting lsp-auto-configure to nil.
  • lsp-mode ships with several predefined servers located in lsp-clients.el which does not require additional package. For the more complex Language Servers like Eclipse JDT, ccls, cquery and haskell we still require separate package due to relatively high code base.
  • lsp-mode handles automatically server failures by asking the user whether he/she wants to restart the server.
  • introduced new command lsp-describe-session which replaces the existing one lsp-capabilities. The command lists the folders that are part of the workspace and the servers that are associated with the corresponding folder.
  • lsp-mode displays information about the running server and it's status in the modeline.
  • lsp-define-stdio-client and lsp-define-tcp-client are replaced with lsp-register-client
  • lsp rely on projectile or project.el now only for suggesting project root. Once you open new file in a project and start lsp it will provide several options(import project, blocklist project, select other directory root). Once you select a root it will be persisted and used for the next sessions.
  • support for multiple language servers per single file and workspace.
  • changed lsp-mode settings to more sensible defaults.
  • Removed all synchronous calls from the server startup.
  • Improved multi-folder support.
