Python language support for Atom-IDE, powered by the Python language server.



ide-python requires Atom 1.21+, Python language server 0.29+ and the atom-ide-ui package to expose the functionality within Atom.

Feature Providers

  • Jedi for Completions, Definitions, Hover, References, Signature Help, and Symbols
  • Rope for Completions and renaming
  • Pyflakes linter to detect various errors
  • McCabe linter for complexity checking
  • pycodestyle linter for style checking
  • Pylint linter to detect various errors
  • Flake8 linter to detect various errors
  • pydocstyle linter for docstring style checking
  • autopep8 for code formatting (preferred over YAPF)
  • YAPF for code formatting


Language Server

Install the language server (0.29.0 or newer) with:

python -m pip install 'python-language-server[all]'

This command will install the language server and all supported feature providers, which can be enabled or disabled in the settings. Checkout the official installation instructions on how to install only the providers you need.

You can verify that everything is correctly installed by running python -m pyls --help from the command line. It should return

usage: pyls [-h] [--tcp] [--host HOST] [--port PORT]
            [--log-config LOG_CONFIG | --log-file LOG_FILE] [-v]

Python Language Server

If you have installed pyls using a non default installation of Python, you can add modify the Python Executable config in the ide-python settings.

Atom Package

Install ide-python and atom-ide-ui from Install in Atom's settings or run:

apm install atom-ide-ui
apm install ide-python


Configuration is loaded from zero or more configuration sources.

  • pycodestyle: discovered in ~/.config/pycodestyle, setup.cfg, tox.ini and pycodestyle.cfg
  • flake8: discovered in ~/.config/flake8, setup.cfg, tox.ini and flake8.cfg

Overall configuration is computed first from user configuration (in home directory), overridden by configuration in the ide-python settings, and then overridden by configuration discovered in the current project.
