| t | As part of markup processing TBWiki expands markup variables | t | |
| in the markup text. | | |
| <p> | | |
| This is done using a python string replacement, and the functionality | | |
| is provided by the "data_class" class. | | |
| <p> | | |
| These are mostly used in themes and by system code. | | |

| </h2> | | |
| The markup on a page can reference these variables, by putting | | |
| a python named-string macro in the markup. | | |
| <p> | | |
| For example, to reference the 'asctime' value, the page should | | |
| have the following markup: | | |
| <p> | | |
| The time is: %(asctime)s | | |
| <p> | | |
| With the resulting text being: | | |
| <p> | | |
| The time is Fri Jun 5 15:04:42 2026 | | |
| <p> | | |
| These can be used in the header and footer pages for a theme, and | | |
| are placed inline with the HTML markup. | | |
