Question 1

How to set up nvim-lint for Python linting?

Accepted Answer

Configure linters_by_ft for the python filetype with tools like flake8 or pylint, and set up an autocmd on BufWritePost to trigger linting, as shown in the Usage section. Ensure the linter is installed and accessible in your PATH.

Question 2

nvim-lint vs ale: which is better for Neovim?

Accepted Answer

nvim-lint is lighter and integrates directly with Neovim's native diagnostics, while ale includes its own LSP client and broader features. Choose nvim-lint if you want a focused linter to complement LSP; pick ale for an all-in-one asynchronous linting and LSP solution.

Question 3

How to create a custom linter in nvim-lint?

Accepted Answer

Define a linter table in the linters namespace with cmd, args, and a parser function using from_pattern, from_errorformat, or for_sarif from the lint.parser module, as detailed in the Custom Linters section. You can also modify built-in linters by wrapping them.

Question 4

Does nvim-lint work with Neovim's LSP client?

Accepted Answer

Yes, it's designed to complement the built-in LSP client by handling languages without servers or where standalone linters are superior, as stated in the Motivation. Diagnostics from both sources integrate via vim.diagnostic.

Question 5

How to change diagnostic display in nvim-lint?

Accepted Answer

Use vim.diagnostic.config to customize display settings, or get a linter's namespace with require('lint').get_namespace() for per-linter configurations, as explained in the Display configuration section.

Question 6

Is nvim-lint safe for open-source or collaborative projects?

Accepted Answer

It can be, but exercise caution: the README warns against using try_lint() in untrusted repositories due to linters executing local executables. Always verify linter sources and consider security implications in shared environments.
