Description   unfold

This module adds Python support to Doom Emacs.

• Syntax checking (doom-package:flycheck)
• Snippets
• Run tests (doom-package:nose, doom-package:pytest)
• Auto-format (with black, requires doom-module::editor format)
• LSP integration (mspyls, pyls, or pyright)

Module flags

+conda

Enable python virtual environment support via Conda.

+cython

Enable support for Cython files support.

+lsp

Enable LSP support for python-mode. Requires doom-module::tools lsp and a langserver (supports mspyls, pyls, and pyright).

+poetry

Enable Python packaging, dependency management, and virtual environment support via Poetry.

+pyenv

Enable Python virtual environment support via pyenv

+pyright

Use the pyright LSP server instead of mspyls or pyls (requires doom-module:+lsp).

+tree-sitter

Leverages tree-sitter for better syntax highlighting and structural text editing. Requires doom-module::tools tree-sitter.

Installation

Enable this module in your doom! block.

This module has no hard requirements, but softly depends on:

• For this module's supported test runners:

  • $ pip install pytest
  • $ pip install nose
• The doom-module::editor format module uses Black for python files: $ pip install black
• doom-package:pyimport requires Python's module pyflakes: $ pip install pyflakes
• doom-package:py-isort requires isort to be installed: pip install isort

• Python virtual environments install instructions at:

  • pyenv
  • Conda
  • Poetry
  • pipenv
• cython requires Cython

Language Server Protocol Support

For LSP support the doom-module::tools lsp module must be enabled, along with this module's doom-module:+lsp flag. By default, it supports doom-package:mspyls and doom-package:pyls, in that order. With the doom-module:+pyright flag, it will try Pyright first.

An alternative LSP server can be used by installing them through the lsp-install-server command, or an external package manager. For example:

• To install pyls: $ pip install python-language-server[all].
• To install mspyls: M-x lsp-install-server RET mspyls.
• To install pyright: $ pip install pyright or $ npm i -g pyright.

Formatter

Formatting is handled using the doom-module::editor format module via black.

TODO Usage

󱌣 This module's usage documentation is incomplete. Complete it?

This module supports LSP. It requires installation of Python Language Server, Microsoft Language Server, or pyright, see LSP Support.

To enable support for auto-formatting with black enable doom-module::editor format.
