Trouble.nvim Filtering by Lsp

Filtering by LSP aka “source”

I like cSpell, but I don’t need a spell checker in my trouble.nvim diagnostics window. This can also be used for other LSPs/sources, but cSpell is the only LSP I want to keep around, just not when I toggle trouble.nvim:

{
 "folke/trouble.nvim",
 opts = {
 modes = {
 diagnostics = {
 filter = function(items)
 return vim.tbl_filter(function(item)
 local source = item["item.source"] or (item.item and item.item.source)
 return not (source and string.find(string.lower(source), "cspell", 1, true))
 end, items)
 end,
 },
 },
 }
}
