Module:Utils

This module provides utility functions used from other modules.

Usage

Add the following line of code at the top of your file.

local Utils = require("Module:Utils")

-- You may then call functions from this module in your script. For example:
local tableLength = Utils.tableLen(myTable)

---

local p = {}

-- Trims and parses the args into a table, then returns the table
function p.normaliseArgs(frame)
  local origArgs = frame:getParent().args
  local args = {}
  
  for k, v in pairs(origArgs) do
    v = mw.text.trim(tostring(v))
    if v ~= '' then
      args[k] = v
    end
  end
  
  return args
end

function p.checkImage(name)
  local icon = name:gsub('%s+', '') .. '_Icon.png'
  if mw.title.makeTitle('File', name).file.exists then
    return name
  else
    return 'NoImage.png'
  end
end
    
return p
