Use D-Scanner as a diagnostics LSP in Neovim LazyVim with none-ls

d-scanner-lsp.lua

Put the following in your ~/.config/nvim/init.lua (after the config.lazy init)

-- Setup dscanner as an nvim-lint command

-- use pattern, get severity and better code handling
local dscanner_pattern = "{filepath}:{line}:{column}:{endColumn}:{type}:{name}:{message}"
local pattern = "([^:]+):(%d+):(%d+):(%d+):([^:]+):([^:]+):(.*)"
local groups = { "file", "lnum", "col", "endcol", "severity", "code", "message" }
local severity_map = {
    warn = vim.diagnostic.severity.WARN,
    error = vim.diagnostic.severity.ERROR,
}

local parser = require("lint.parser").from_pattern(pattern, groups, severity_map, {
    source = "dscanner",
})

require("lint").linters.dscanner = {
    name = "dscanner",
    cmd = "~/bin/dscanner",
    stdin = false, -- or false if it doesn't support content input via stdin. In that case the filename is automatically added to the arguments.
    append_fname = true, -- Automatically append the file name to `args` if `stdin = false` (default: true)
    args = { "lint", "--errorFormat=" .. dscanner_pattern }, -- list of arguments. Can contain functions with zero arguments that will be evaluated once the linter is used.
    stream = "stdout", -- ('stdout' | 'stderr' | 'both') configure the stream to which the linter outputs the linting result.
    ignore_exitcode = true, -- set this to true if the linter exits with a code != 0 and that's considered normal.
    env = nil, -- custom environment table to use with the list_extendl process. Note that this replaces the *entire* environment, it is not additive.
    parser = parser,
}

require("lint").linters_by_ft = {
    d = { "dscanner" },
}

vim.api.nvim_create_autocmd({ "BufWritePost" }, {
    callback = function()
        -- try_lint without arguments runs the linters defined in `linters_by_ft`
        -- for the current filetype
        require("lint").try_lint()

        -- You can call `try_lint` with a linter name or a list of names to always
