How to set the custom diagnostic icons

[liuhq]

as the title says, I am sorry but I didn't find the relevant field.

(copy from the help document)

diagnostics = {
    prompt            = 'Diagnostics❯ ',
    cwd_only          = false,
    file_icons        = true,
    git_icons         = false,
    diag_icons        = true,
    diag_source       = true,   -- display diag source (e.g. [pycodestyle])
    icon_padding      = '',     -- add padding for wide diagnostics signs
    multiline         = true,   -- concatenate multi-line diags into a single line
    -- severity_only:   keep any matching exact severity
    -- severity_limit:  keep any equal or more severe (lower)
    -- severity_bound:  keep any equal or less severe (higher)
}

Looks like this is set by vim.diagnostics.config

fzf-lua/lua/fzf-lua/providers/diagnostic.lua

Lines 74 to 80 in 04a1bb6

	local sign_confs = vim.diagnostic.config().signs
	local level = vim.diagnostic.severity[k:upper()]
	if type(sign_confs) ~= "table" or utils.tbl_isempty(sign_confs) then sign_confs = nil end
	opts.__signs[v.severity].text =
	(not opts.diag_icons or not sign_confs or not sign_confs.text or not sign_confs.text[level])
	and v.default or vim.trim(sign_confs.text[level])
	opts.__signs[v.severity].texthl = v.name

Correct, here’s an example how I set the diag icons in my personal config:

Thanks! : )

But I set it, and it had no effect (following is the part of my lsp.lua, loaded before the fzf-lua)

if client:supports_method('textDocument/publishDiagnostics') then
    vim.diagnostic.config({
        --- something others
        signs = {
            text = {
                [vim.diagnostic.severity.ERROR] = "",
                [vim.diagnostic.severity.WARN] = "",
                [vim.diagnostic.severity.HINT] = "",
                [vim.diagnostic.severity.INFO] = "",
            },
            numhl = {
                [vim.diagnostic.severity.ERROR] = 'ErrorMsg',
                [vim.diagnostic.severity.WARN] = 'WarningMsg',
            },
        },
    --- something others
    }, vim.lsp.diagnostic.get_namespace(args.data.client_id))
end

then yes, I also read the source code just now, and I found that we can configure like this (works fine for me 🥳):

require('fzf-lua').setup({
    diagnostics = {
        signs = {
            ['Error'] = { text = "" },
            ['Warn'] = { text = "" },
            ['Hint'] = { text = "" },
            ['Info'] = { text = "" },
        },
    },
})

(from the source code)

fzf-lua/lua/fzf-lua/providers/diagnostic.lua

Lines 92 to 98 in 04a1bb6

	-- from user config
	if opts.signs and opts.signs[k] and opts.signs[k].text then
	opts.__signs[v.severity].text = opts.signs[k].text
	end
	if opts.signs and opts.signs[k] and opts.signs[k].texthl then
	opts.__signs[v.severity].texthl = opts.signs[k].texthl
	end

Correct, that’s another option :)
