How to get the list of attached sources

[SamiAlsubhi]

I am trying to get all the attached Lsps and null-ls sources. I am able to get the attached Lsps. For null-ls active resources i am getting all the resources rather than the active ones! how can i get only the active ones?

local null_ls= require('null-ls')

local lsp_info= function()
    local active_clients = ''
    local no_clients = 'No Active Lsp'
    local buf_ft = vim.api.nvim_buf_get_option(0, 'filetype')
    local clients = vim.lsp.get_active_clients()
    if next(clients) ~= nil then
      for _, client in ipairs(clients) do
        if client.name ~= 'null-ls' then
          local filetypes = client.config.filetypes
          if filetypes and vim.fn.index(filetypes, buf_ft) ~= -1 then
            active_clients = active_clients ..','.. client.name
          end
        end
      end
    end
    
    local sources = null_ls.get_sources()
    if next(sources) ~= nil then
      for _,source in ipairs(sources)  do
        if null_ls.is_registered(source.name)  then
          active_clients = active_clients ..','.. source.name
        end 
      end
    end
--
      
    if active_clients == '' then
      return no_clients
    end
    return active_clients:sub(2)
end

You can get a list of active sources for the current buffer using require("null-ls.sources").get_available(vim.bo.filetype) (replace with the filetype of the buffer you want to check if you care about buffers other than the current).
