.tmLanguage -- how to include / exclude a variable

I am looking for examples to include / exclude a couple of variables as defined within a .tmLanguage file.

Example 1 -- highlight the whole enchilada, including both variables:

{\code_one*[variable_one]{variable_two}}

Example 2 -- highlight the whole enchilada, less either or both variables:

{\code_two*[variable_three]{variable_four}}

include_variable_text -- e.g., \hspace*{3.45in}; \begin{singlespace*}; \end{document}.

.tmLanguage
