a protected lua require


local du = require "lib/dtutils"
local status, lib = du.prequire(req_name)

req_name - string - the filename of the lua code to load without the “.lua” filetype


prequire is a protected require that can survive an error in the code being loaded without bringing down the calling routine.


status - boolean - true on success lib - if status is true, then the code, otherwise an error message


local status, lib = prequire("lib/dtutils.file") 

which would load lib/dtutils/file.lua which would return a status of true and the reference to the library.
