rate my code prog?



function nfa:translate_state_numbers(offset)
  self.transition_table = t.remap(self.transition_table,
                                  function(i,transitions)
                                    return i + offset
                                  end,
                                  function(i,transitions)
                                    return t.map(transitions,
                                                 function(state_set)
                                                   return t.map_keys(state_set,
                                                                     function(state_number)
                                                                       return state_number + offset
                                                                     end)

which is better?



function nfa:translate_state_numbers(offset)
  self.transition_table = t.remap(
    self.transition_table,
    function(i,transitions)      
      return i + offset            
    end,                         
    function(i,transitions)      
      return t.map(
        transitions,
        function(state_set)                     
          return t.map_keys(
            state_set,
            function(state_number)                                  
              return state_number + offset                            
            end)                                                    
        end)
    end)                         
  self.state_status_table = t.map_keys(
    self.state_status_table,
    function(state_number)            
      return state_number + offset      
    end)                              
  self.start_state = t.map_keys(
    self.start_state,
    function(state_number)

Ever heard of comments?

looks like Lua. Ugly-ass terrible lua, but lua nonetheless. you can write shit in any language.

Many job interviews require a candidate to read uncommented code, and describe what it does. Thus, one who needs comments to read my code is an inadequate candidate for a job in programming.

not python, not relevant

well, it's almost python. Lua is like python with its limbs chopped off.

and lua is slow as fuck compared to python

every time i see a game use lua for scripting i feel the urge to import facepalm

It's not nice to call a quadriplegic slow. It's not Lua's fault.

looking at the code again... anonymous functions??? what the fuck??? name those fucking things.

Name: Anonymous 2011-09-24 14:21

actually,


#!/usr/bin/python

for i in range(10000000): pass

runs much slower than


#!/usr/bin/lua

for i=1,10000000 do
end

and the python version seems to use my hard drive for some reason. Therefore, your argument is invalid and Lua is faster than python.

use xrange faggot

(function(self) self(self, 'How about:') end)(function(self, message) print(message); self(self, message .. ' no ' .. message) end)

thanks for the tip, but after making the change, lua is still fasta:


lua-fan@luaisdabest>>cat loop.lua
#!/usr/bin/lua

for i=1,10000000 do
end
lua-fan@luaisdabest>>cat loop.py
#!/usr/bin/python

for i in xrange(10000000): pass
lua-fan@luaisdabest>>time loop.lua

real    0m0.877s
user    0m0.852s
sys     0m0.004s
lua-fan@luaisdabest>>time loop.py

real    0m6.677s
user    0m6.616s
sys     0m0.036s

Why are you running lua interpreted?  Just load it in the JIT and eviscerate him.

I don't have it at the moment, unfortunately. Also to benchmark luajit against python, you would have to use some kind of jit for python, or compile it to C or something.
