diag_ignore.nvim automates inserting of annotations to disable diagnostic checks in a line of code. Upon triggering the diag_ignore mapping, the user is presented with all the diagnostic messages on the current line. If the user selects a diagnostic code, the code will be ignored on the current line.

Currently supported languages are Lua (lua_ls) and Python (basedpyright, pyright).

Use your favourite plugin manager to install diag_ignore.nvim. For example, a minimal plugin spec with Lazy.nvim:

    {
      "amadanmath/diag_ignore.nvim",
      keys = {
        { '<Leader>ci', '<Plug>(diag_ignore)', mode = 'n', desc = 'Diagnostic: ignore' },
      },
      opts = {},
    }

The default options are:

    opts = {
      ignores = {
        python = { 'endline',  ' # pyright: ignore[', ']' },
        lua =    { 'prevline', '---@diagnostic disable-next-line: ' },
      },
    },

The ignores option lists the supported filetypes. Each value is a table:

    [filetype] = { type, prefix, suffix, joiner }

If suffix is nil, the default is '' (empty string). If joiner is nil, the default is ', ' (comma and space).

If type is 'endline', the annotation will be appended to the current line. For example, in Python, invoking diag_ignore.nvim on

    1

will result in

    1 # pyright: ignore[reportUnusedExpression]

If type is 'prevline', the annotation will be inserted on the previous line. For example, in Lua, invoking diag_ignore.nvim on

    1

will result in

    ---@diagnostic disable-next-line: exp-in-action
    1

If an annotation already exists and an additional diagnostic code is selected, the code will be inserted into the existing annotation, separated from the existing codes by joiner.

The default Python config is based on pyright/basedpyright. If you are using mypy, you will have to change the Python config as follows:

    python = { 'endline',  ' # type: ignore[', ']' },
