Re-learning Vim (5)

Revisit syntax checkers and beyond

Let me revisit recent situation over static syntax checkers mentioned in Re-learning Vim (2).

Under NeoVim (>0.7) with Lua, LSP ecosystem around nvim-lspconfig can be used to access local syntax checkers and code style formatter using null-ls.nvim.

• upstream: null-ls.nvim.

Many required packages for this seem to be compiled and installed by

• currently: nvim-lsp-installer (upstream: https://github.com/williamboman/nvim-lsp-installer)
• Next: mason.nvim (upstream: https://github.com/williamboman/mason.nvim)

Shell with LS

• static syntax checker package: shellcheck (deb)
• upstream: shellcheck
• use configuration file: ~/.shellcheckrc. See its section in manpage for shellcheck

# SC2006: Use $(...) notation instead of legacy backticked `...`.               
disable=SC2006

Python

My old ways

• static syntax checker package: flake8 (deb)
• upstream: flake8
• use configuration files to set them quiet to avoid excessive noise. ~/.pycodestyle

[pycodestyle]
count = False
ignore = E203,E226,E302,E41
max-line-length = 160
statistics = True

• static syntax checker packages: pylint (deb)
• upstream: pylint
• configuration: ~/.plintrc; pylintrc or project.toml (cwd)

My new ways with LS

• install backend python tool with pip install pyright
• install language server with npm i -g pyright
• Static type checker for Python
• upstream: Pyright

Independent reformatter

I also use an independent code re-formatter package: black.

• upstream: black
• configuration file (command line tool): [tool.black] section in pyproject.toml
• Adjust other tools to max-line-length = 88

One more tool is isort for import.

• upstream: isort

Lua with LS

• rust cargo package / Node.js npm package
• upstream: StyLua
• configuration file: .stylua.toml (project root)

column_width = 120                                                                                                                                                           
line_endings = "Unix"
indent_type = "Spaces"
indent_width = 2
quote_style = "AutoPreferDouble"
no_call_parentheses = true
collapse_simple_statement = "Always"

Others with LS

It seems there are supports not only on HTML but also markdown etc.
