How to debug Lua remotely?

Question

I\'m searching for the best way to debug Lua remotely, ( like from a web browser ).

I saw RemDebug, but the last project update was done on 2006. It works with Lua 5.0 a

I'm not sure if this is right. Hope it helps though:

Source: http://www.keplerproject.org/remdebug/example.html

This is an example of a debugging session of the following script (test.lua):

 1    require"remdebug.engine"
 2
 3    remdebug.engine.start()
 4    
 5    local tab = {
 6      foo = 1,
 7      bar = 2
 8    }
 9
10    print("Start")
11
12    function bar()
13      print("In bar 1")
14      print("In bar 2")
15    end
16
17    for i = 1, 10 do
18      print("Loop")
19      bar()
20      tab.foo = tab.foo * 2
21    end
22
23    print("End")

First run the RemDebug controller:

% lua50 controller.lua Lua Remote Debugger Run the program you wish to debug At this moment you can run your target program (in another window):

% lua50 test.lua Now go back to the window where you ran controller.lua (this assumes you are running test.lua inside C:\development\kepler on a Windows system):

Paused at file C:/development/kepler/test.lua Type 'help' for commands

basedir C:/development/kepler/ New base directory is C:/development/kepler/ basedir C:/development/kepler/ step Paused at file C:/development/kepler/test.lua line 6 over Paused at file C:/development/kepler/test.lua line 7 over Paused at file C:/development/kepler/test.lua line 10 over Paused at file C:/development/kepler/test.lua line 15 setb test.lua 19 run You can change to the application window anytime to see its output. Back to the debugger session:

Paused at file C:/development/kepler/test.lua line 19
