Neovim Python Setup

Some Neovim plugins require Python <= 3.13. To avoid conflicts with newer system Python versions, a dedicated virtual environment is used.

Initial Setup

# Create the venv with Python 3.13
uv venv --python 3.13 ~/.config/nvim/.venv

# Activate and install pynvim
source ~/.config/nvim/.venv/bin/activate
uv pip install pynvim

The init.lua is already configured to use this venv via vim.g.python3_host_prog.

Verification

Run :checkhealth provider in Neovim to verify the Python provider is working correctly.

Mason Packages

LSP servers are automatically installed via mason-lspconfig. For non-LSP packages (formatters, linters, DAP adapters, tools), run the following command in Neovim:

:MasonInstall clang-format cmakelang gofumpt goimports luaformatter mdformat prettier prettierd pyproject-fmt sql-formatter sqlfmt stylua taplo yamlfix yamlfmt buf checkmake checkstyle cmakelint codespell commitlint cpplint gitleaks gitlint golangci-lint jsonlint luacheck markdownlint markuplint misspell mypy protolint pydocstyle revive semgrep shellcheck stylelint systemdlint yamllint bash-debug-adapter codelldb cpptools debugpy delve codeql gh gitui iferr jq nomad terraform tree-sitter-cli uv wasm-language-tools
