typos ("occurence" => "occurrence")

-- Module for different search and replace operations on strings.
local p = {}

-- Takes one string parameter, and returns the string with all characters with special meaning for Lua patterns escaped with a preceding `%`.
function p.escape_pattern(text)
-- Replaces each occurrence of any of ().%+-*?[^$ with a `%` and then the character.
local r = string.gsub(text, "[%(%)%.%%%+%-%*%?%[%^%$]", "%%%1")
return r
end

-- Returns the first parameter, with all occurrences of the second parameter replaced with the third parameter.
-- All special characters are ignored: {{#invoke:StringReplace|replace_all|test.a%1$foo|%1|bar}} results in `test.abarfoo`.
