 | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
Usage
String utilities for Module:US elections imagemap.
stripspaces(str)strips spaces fromstr.split(str, sep)splitstrinto a table of strings at eachsep.
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}}.
local p = {}
function p.stripspaces(str)
return str:gsub("^%s*(.-)%s*$", "%1") -- trim spaces
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.stripspaces(word) end
return parts
end
return p
