Usage

String utilities for Module:US elections imagemap.

• stripspaces(str) strips spaces from str.
• split(str, sep) split str into a table of strings at each sep.

Unlike many other string utilities on Wikipedia, these are designed to be called from another Lua script easily — not to be called directly with {{#invoke}}.

function p.nowiki(str)
	return String2.nowiki({args = {str}}) -- I wish people would write functions for LUA, not for WIKIPEDIA, c'mon
end

function p.split(str, sep) -- split string by separator and return table
  sep = sep or "%s"
  local parts = {}
  for word in string.gmatch(str, "[^" .. sep .. "]+") do parts[#parts+1] = p.nowiki(word) end
  return parts
end

function p.listmerge(t1, t2) -- only works on tables that are lists, not dictionaries
	for i, j in ipairs(t2) do
		table.insert(t1, j)
	end
	return t1
