    ---dump
    ---@param obj table @object to dump
    ---@param name string
    function dump(obj, name)

    ---dump_log dump into the log
    ---@param obj table
    ---@param name string
    function dump_log(obj, name)

    ---log easy way to log multiple object, string, function
    --- default with WARN level
    function log(...)

    ---dump_lua
    ---@param obj ebitop @object to dump out
    ---@param name string @name for the description
    ---@param sb sbuffer @buffer writer
    ---@param indent_depth number @indention level
    ---@return string @ dumpped text
    function dump_lua(obj, name, sb, indent_depth)

    ---dump_class dump LUA class with more readable way,and suits for IDE code intellisense
    ---@param obj ebitop @object to dump out
    ---@param name string @name for the description
    ---@param sb sbuffer @buffer writer
    ---@param indent_depth number @indention level
    ---@return string @ dumpped text
    function dump_class(obj, name, sb, indent_depth)

    ---parse_func parse function and return function details
    ---@param func function @func to parse
    ---@param fname string @function name
    ---@param with_self boolean @ default :(arg1, arg2), with_self .(self, arg1, arg2)
    ---@return table
    function parse_func(func, fname, with_self)

    ---parse_code
    ---usage:
    --- call this function in any code. It will search for local object within current lua file context from to to bottom
    --- When encounter the 'local end_list' variable, the parse process will stop.
    --- it will return well formatted function stub with parameters arrays( the param name will be lost due to the lua vm)
    --- ALSO THE CODE SOURCE FILE AND LINE NUMBER, IT'S VERY USEFUL TO DETECT THE CLASS INHERTS RELATIONS.
    function parse_code()

usage:

    location /test.lua {
      content_by_lua_block {
        local cookie = require("resty.cookie")
        local cache = require('resty.lrucache')

        ----- code list end here
        local end_list
        local say = ngx.say
        require('dump')
        say('<pre>')
        local foo = {
         name = 'hello',
         say = function(word, bluh)
         end,
         is_bad = false,
         id = 123456,
         obj = {
          key = 'key',
          value = 119,
          is_bad = true
         },
         num_list = { 1, 2, 3, 4, 5 },
         str_list = { 'a', 'b', 'c' },
         obj_list = { { name = 1, value = 2 }, { name = 1, value = 2 }, { name = 1, value = 2 }, { name = 1, value = 2 } }
        }

        say(dump_lua(foo, 'foo'))
        say(dump_class(cache, 'lrucache'))
        dump(ngx, 'ngx')
        --- nginx log output
        dump_log(foo, 'hello')
        log('Winner Winner', 'Chicken dinner!', foo, table, ngx)
        }
    }

     say = function(arg1) end,			-- @./approot/test.lua @line: 25
