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.

External linter of interest

For Perl, perltidy looks interesting. See how Debian devscripts source uses it.
