Project description


Yet another Jedi Python language server


  • Python >= 3.6
  • pygls ~= 0.9
  • Jedi >= 0.17.1
  • pyflakes ~= 2.2
  • pycodestyle ~= 2.5
  • yapf ~=0.30

Optional requirements

  • mypy

Implemented features

  • textDocument/completion
  • textDocument/hover
  • textDocument/signatureHelp
  • textDocument/definition
  • textDocument/references
  • textDocument/publishDiagnostics
  • textDocument/documentSymbol
  • textDocument/codeAction (Inline variable)
  • textDocument/formatting
  • textDocument/rangeFormatting
  • textDocument/rename
  • textDocument/documentHighlight

Initialization option

Also one can set VIRTUAL_ENV or CONDA_PREFIX before running anakinls so Jedi will find proper environment. See get_default_environment.


Diagnostics are published on document open and save.

Diagnostics providers:

  • Jedi

    See get_syntax_errors.

  • pyflakes

  • pycodestyle

    Server restart is needed after changing one of the configuration files.

  • mypy

    Install mypy in the same environment as anakinls and set mypy_enabled configuration option.

Configuration options

Configuration options must be passed under anakinls key in workspace/didChangeConfiguration notification.

Available options:

  • pyflakes_errors - Diagnostic severity will be set to Error if Pyflakes message class name is in this list. See Pyflakes messages.

    Default: ['UndefinedName'].

  • help_on_hover - Use help instead of infer for textDocument/hover.

    Default: True.

  • mypy_enabled - Use mypy to provide diagnostics.

    Default: False.

  • pycodestyle_config - In addition to project and user level config, specify pycodestyle config file. Same as --config option for pycodestyle.

    Default: None.

  • completion_snippet_first - Tweak sortText property so snippet completion appear before plain completion.

    Default: False.

  • yapf_style_config - Either a style name or a path to a file that contains formatting style settings.

    Default: 'pep8'

Configuration example

Here is eglot configuration:

(defvar my/lsp-venv nil
  "Name of virtualenv.
Set it in project's dir-locals file.")

(defclass my/eglot-anakinls (eglot-lsp-server) ()
  "Own eglot server class.")

(cl-defmethod eglot-initialization-options ((_server my/eglot-anakinls))
  "Pass initialization param to anakinls."
  `(:venv ,(when my/lsp-venv
              (concat "~/.virtualenvs/" my/lsp-venv)))))

;; Add this server to eglot programs to handle python-mode and run `anakinls'
(add-to-list 'eglot-server-programs
             '(python-mode my/eglot-anakinls "anakinls"))

;; Also treat UnusedVariable as error
(setq-default eglot-workspace-configuration
              '((:anakinls :pyflakes_errors ["UndefinedName" "UnusedVariable"])))


pip install anakin-language-server
