Debug
This dialog is invoked by calling debug.debug () from within a Lua script. You can use it to inspect variables, do a traceback, enter debugging commands, or abort the script. Source The short form of the source of this script. If loaded from a file it will be the filename preceded by the "@" symbol. First, last lines If known, the first and last line numbers in which the current function was defined. Current line The line number inside the script at which the debug.debug () command resides. What function is This will be one of: Lua - a regular Lua function main - inside the main Lua chunk (that is, not inside a function) C - a C function Name If it can be determined, the name of the current function, followed by what the name is in brackets. (eg. "myfunction (local)" ). Function The function address. Number of upvalues How many upvalues this function has. Show upvalues Clicking this runs a small script to display the upvalues of the current function, if any, in the output window. The script looks like this:
    do
    local i, name, val = 1
    local t = debug.getinfo (3, 'f')
    local f = t.func
    -- keep going until we run out of values
    repeat
      name, val = debug.getupvalue (f, i)
      if name then
        ColourNote ('limegreen', 'black', name .. ' = ' .. tostring (val))
        i = i + 1
      end
    until not name
    ColourNote ('limegreen', 'black', tostring (i - 1) .. ' upvalue(s)')
    end -- of local block
Show locals Clicking this runs a small script to display the local variables of the current function, if any, in the output window. The script looks like this:
    do local i, name, val = 1
    repeat
     name, val = debug.getlocal (3, i)
      if name then
        ColourNote ('limegreen', 'black', name .. ' = ' .. tostring (val))
        i = i + 1
      end
    until not name
    ColourNote ('limegreen', 'black', tostring (i - 1) .. ' local(s)')
    end -- local block
Traceback Clicking this runs a small script do display the traceback information, namely:
    ColourNote ('limegreen', 'black', debug.traceback ())
Command You can type Lua commands into this window and press <Enter> (or click on Do Command). The command you entered is sent to the Lua interpreter to be executed in the context of the current script. For example, you could print or change global variables. The current command is remembered from one debug session to the next. Edit... Click this to edit the current contents of the command window in a larger dialog box. This larger box has access to function help, and function-name completion. Do command Sends the contents of the "command" box to the Lua interpreter. Continue execution Lets the script that called debug.debug () continue executing. Pressing <Esc> to dismiss the dialog has the same effect. Abort script Aborts the calling script with the error "Script aborted". See Also ...
