A Python 2.7 and 3.5+ implementation of the Language Server Protocol.
The base language server requires Jedi to provide Completions, Definitions, Hover, References, Signature Help, and Symbols:
pip install spyder-pyls
If the respective dependencies are found, the following optional providers will be enabled:
- Rope for completions and renaming
- Pyflakes linter to detect various errors
- McCabe linter for complexity checking
- pycodestyle linter for style checking
- pydocstyle linter for docstring style checking (disabled by default)
- autopep8 for code formatting
- YAPF for code formatting (preferred over autopep8)
Optional providers can be installed using the extras syntax. To install YAPF formatting for example:
pip install 'spyder-pyls[yapf]'
All optional providers can be installed using:
pip install 'spyder-pyls[all]'
If you get an error similar to 'install_requires' must be a string or list of strings then please upgrade setuptools before trying again.
pip install -U setuptools
Installing these plugins will add extra functionality to the language server:
- pyls-mypy Mypy type checking for Python 3
- pyls-isort Isort import sort code formatting
- pyls-black for code formatting using [Black(https://github.com/ambv/black)
Please see the above repositories for examples on how to write plugins for the Python Language Server. Please file an issue if you require assistance writing a plugin.
Configuration is loaded from zero or more configuration sources. Currently implemented are:
- pycodestyle: discovered in
~/.config/pycodestyle,setup.cfg,tox.iniandpycodestyle.cfg - flake8: discovered in
~/.config/flake8,setup.cfg,tox.iniandflake8.cfg
The default configuration source is pycodestyle.
- Code completion
- Code linting (Warnings and errors)
To run the test suite:
pip install .[test] && tox
The Python language server can be developed against a local instance of Spyder IDE.
- Install it with
pip install -e . - Start Spyder in debug mode (
python bootstrap.py --debug) - Check logs for both client and server in
~/.spyder-py3/lsp-logs
