Документация для Модуль:FileExists Перейти к коду ↴ [ править | очистить ]

This module provides a "safe" version of mw.title's .fileExists method, that does not raise an error when the expensive parser function limit is exceeded.

Использование[]

local fileExists = require('Module:FileExists')

-- ...

local file
if fileExists('File:My example file.png') then
  file = 'File:My example file.png'
end


local libraryUtil = require('libraryUtil')


return function(file)
  libraryUtil.checkTypeMulti('fileExists', 1, file, { 'string', 'table' })

  if type(file) == 'string' then
    file = mw.title.new(file)
  end

  local success, result = pcall(function(x) return x.fileExists end, file)
  return (success and result)
end
