LUA Pattern to retrieve a specific part of text from a string

So I have a string in Lua that is exactly like the following:

[[
  en[What is your job]
  pt[Qual é o seu trabalho?]
]]

As you might expect, I want to sometimes retrieve anything inside "en[]" and in other times "pt[]" and put the text inside a new variable.

Any ideas?

Solution

  • Edit: Improved speed by removing some concatenation.

    This should work:

        String = [[
        en[What is your job]
        pt[Qual é o seu trabalho?]
    ]]

    function RetrieveElementFromString( String, Element, ContainerOpen, ContainerClose ) -- String is the "[[]]" part.
        return String:match( Element .. ContainerOpen .. '(.-)' .. ContainerClose )
    end

    print( RetrieveElementFromString( String, 'en', '%[', '%]' ) ) -- > What is your job
