మాడ్యూల్:SimpleDebug
Contains a functions to help debug the lua modules. It allows to collect and view the values of several variables and/or points in your lua program, from a module (which is usual) or in several modules (which are required from the main module).
It is designed so that its functions are called from within the module that is to be debugged, calls that will have to be part of the code (of the module that you have designed, or that you want to improve or adapt) until you decide to delete them (when you already have determined the bug). Thus, you do not have to call any of its functions from an invoke.

Examples
మార్చుOne point to watch
మార్చుFollowing the flow
మార్చుlocal SD = require "Module:SimpleDebug"
return SD.v ('Here is reached')
returns:
Here is reached
Number of decimal places and value of a variable
మార్చుlocal SD = require "Module:SimpleDebug"
SD.dec = 2
return SD.v (1/3)
returns:
0.33
Nohtml
మార్చుlocal SD = require "Module:SimpleDebug"
SD.nohtml = true
return SD.v ("<b>bold</b>")
returns:
"⪡b⪢bold⪡/b⪢"
Plaintext
మార్చుlocal SD = require "Module:SimpleDebug"
SD.plaintext = true
return SD.v ("<b>bold</b>")
returns:
"bold"
The value of several variables
మార్చుlocal SD = require "Module:SimpleDebug"
local a = 12
local b = 'Hello'
return SD.v (a,b)
returns:
12 • "Hello"
Non-assigned variable detection
మార్చుlocal SD = require "Module:SimpleDebug"
local a = true
return SD.v (a,b)
returns:
true • nil
The value of a table
మార్చుlocal SD = require "Module:SimpleDebug"
local a = {1, tab='a', 'b'}
return SD.v (a)
returns: { 1, "b", [tab]="a", }
local SD = require "Module:SimpleDebug"
local a = {{1,2,3},{4,5,6},{7,8,9}}
return SD.v (a)
returns:
{ [1] = {1, 2, 3, }, [2] = {4, 5, 6, }, [3] = {7, 8, 9, }, }
local SD = require "Module:SimpleDebug"
local a = {{First=1,2,3},{4,Second=5,6},{7,8,9}}
return SD.v (a)
returns:
{ [1] = {2, 3, [First]=1, }, [2] = {4, 6, [Second]=5, }, [3] = {7, 8, 9, }, }
local SD = require "Module:SimpleDebug"
SD.allidx = true
local a = {{1,2,3},{4,5,6},{7,8,9}}
return SD.v (a)
returns:
{ [1]={[1]=1, [2]=2, [3]=3, }, [2]={[1]=4, [2]=5, [3]=6, }, [3]={[1]=7, [2]=8, [3]=9, }, }
Usually, you implement these functions with error function:
local SD = require "Module:SimpleDebug"
local a = {{1,2,3},{4,5,6},{7,8,9}}
error (SD.v (a))
displays:
Lua error:Module:YourModule:Line:{
[1] = {1, 2, 3, }, [2] = {4, 5, 6, }, [3] = {7, 8, 9, }, }
All values of a table in multiline
మార్చుlocal SD = require "Module:SimpleDebug"
SD.tab.oneline = false
local a = {{First=1,2,3},'Middle',{4,Second=5,6}}
return SD.v (a)
retorna:
{ [1] = { [1] = 2, [2] = 3, ["First"] = 1, }, [2] = "Middle", [3] = { [1] = 4, [2] = 6, ["Second"] = 5, }, }
The value of several variables with their name in a point
మార్చుlocal SD = require "Module:SimpleDebug"
local a = 12
local b = 'Hello'
return SD.nv ('a',a,'b',b)
returns:
a: 12 • b: "Hello"
