This module helps to debug lua errors in modules using the console.


It contains a method that emulates a full frame in the console, and allows one to debug some lua modules without having to save them.


Within the console import the module and initialize it. First import this module, then use the frame function to generate a new frame.

local dbg = require("Dev:Debug")
local fakeFrame = dbg.frame({param1, param2})


Follow the following steps:

  1. Create a test module, e.g. Module:Sandbox
  2. Paste the following code into the text area
local p = {}

function p.test(frame)
    return "Hello " .. (frame.args[1] or "missy")

function p.test2(frame)
    return "Hello " .. (frame:getParent().args[1] or "missy")

return p
  • Now paste the following text in the debug console of a test module
-- Console code
local dbgModule = require("Dev:Debug")

-- Then use the frame method to create a fake test frame.
local childFrame = {"Child"}
local parentFrame = {"Parent"}
local frame = dbgModule.frame(childFrame, parentFrame)

-- The method above accepts two parameters as tables, one represents the parent
-- frame, and the other the child. Finally pass this frame to a function:
local message1 = p.test(frame)
local message2 = p.test2(frame)

print("Message 1:", message1)
print("Message 2:", message2)
Message 1:	Hello Child
Message 2:	Hello Parent

PseudoFrame functions[]

The frame method currently only supports the functions in the table below:

Function Notes
getParent() This works pretty much like the original
preprocess() Simply returns the text as the frame isn't available to do preprocessing
showargs() Shows a list of arguments contained in both parent and child frame
setargs Sets the arguments
.frame Creates a frame object
