Show current code formatter in Lualine (Using conform.nvim)

[mvsrgc]

Hi everyone, just wanted to share a custom component I made for my lualine that displays the current formatter(s). I made this because I want to know if it's the LSP formatter or a custom one formatting my code.

Custom formatter:

No formatter:

LSP formatter:

ins_left({
    function()
        -- Check if 'conform' is available
        local status, conform = pcall(require, 'conform')
        if not status then
            return 'Conform not installed'
        end

        local lsp_format = require('conform.lsp_format')

        -- Get formatters for the current buffer
        local formatters = conform.list_formatters_for_buffer()
        if formatters and #formatters > 0 then
            local formatterNames = {}

            for _, formatter in ipairs(formatters) do
                table.insert(formatterNames, formatter)
            end

            return '󰷈 ' .. table.concat(formatterNames, ' ')
        end

        -- Check if there's an LSP formatter
        local bufnr = vim.api.nvim_get_current_buf()
        local lsp_clients = lsp_format.get_format_clients({ bufnr = bufnr })

        if not vim.tbl_isempty(lsp_clients) then
            return '󰷈 LSP Formatter'
        end

        return ''
    end,
})
