[Lib] beProfiler

[paladin-t]

Fast Lua function profiler for Bitty Engine. It is ported from charlesmallah/lua-profiler.

Code:

require 'libs/beProfiler/beProfiler'

function setup()
  -- Start profiling.
  beProfiler.start()
end

function quit()
  -- Stop profiling.
  beProfiler.stop()
  -- Get report path.
  local path = Project.main:fullPath()
  if Path.existsFile(path) then
    path = FileInfo.new(path):parentPath()
  elseif Path.existsDirectory(path) then
    path = DirectoryInfo.new(path):parentPath()
  end
  path = Path.combine(path, 'profiler.log')
  -- Report it.
  beProfiler.report(path)

  print('Report: ' .. path)
end

function update(delta)
  ...
end

Output:
