- * Line Tests
- *
- * The following tests work on term_line objects and verify their behavior when
- * we modify them. To verify and set line layouts, we have two simple helpers
- * to avoid harcoding the cell-verification all the time:
- * line_set(): Set a line to a given layout
- * line_assert(): Verify that a line has a given layout
- *
- * These functions take the line-layout encoded as a string and verify it
- * against, or set it on, a term_line object. The format used to describe a
- * line looks like this:
- * example: "| | A | | | | | | 10 *AB* |"
- *
- * The string describes the contents of all cells of a line, separated by
- * pipe-symbols ('|'). Whitespace are ignored, the leading pipe-symbol is
- * optional.
- * The description of each cell can contain an arbitrary amount of characters
- * in the range 'A'-'Z', 'a'-'z'. All those are combined and used as term_char_t
- * on this cell. Any numbers in the description are combined and are used as
- * cell-age.
- * The occurrence of a '*'-symbol marks the cell as bold, '/' marks it as italic.
- * You can use those characters multiple times, but only the first one has an
- * effect.
- * For further symbols, see parse_attr().
- *
- * Therefore, the following descriptions are equivalent:
- * 1) "| | /A* | | | | | | 10 *AB* |"
- * 2) "| | /A** | | | | | | 10 *AB* |"
- * 3) "| | A* // | | | | | | 10 *AB* |"
- * 4) "| | A* // | | | | | | 1 *AB* 0 |"
- * 5) "| | A* // | | | | | | A1B0* |"
- *
- * The parser isn't very strict about placement of alpha/numerical characters,
- * but simply appends all found chars. Don't make use of that feature! It's
- * just a stupid parser to simplify these tests. Make them readable!
