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}}.
