title: WikiText parser mode: macro examples
type: text/vnd.tiddlywiki
\define boringtable()
|cell one|cell two|
|cell three|cell four|
\end
With the macro `boringtable` defined as:
<$codeblock code=<<boringtable>>/>
then
<table><<wikitext-example-table-header>><tbody>
<<wikitext-example-table-row 1 "* <<boringtable>>">>
<<wikitext-example-table-row 2 """* <div>
<<boringtable>>
</div>
""">>
<<wikitext-example-table-row 3 "* <$macrocall $name=boringtable/>">>
<<wikitext-example-table-row 4 "* <$macrocall $name=boringtable></$macrocall>">>
<<wikitext-example-table-row 5 """* <$macrocall $name=boringtable>
</$macrocall>""">>
</tbody></table>
The list syntax is recognised in [[block mode|Block Mode WikiText]] and the enclosed contents are parsed using [[inline mode|Inline Mode WikiText]]. When the parser encounters a [[wikitext macro call|Macro Calls in WikiText]] it will use the current parse mode to parse the contents of the macro. The contents of the macro contains table syntax which is only recognised in [[block mode|Block Mode WikiText]].
Therefore, in #1 above the table syntax is not recognised. In #2 above, the blank line after the open `div` tag moves the parser back into [[block mode|Block Mode WikiText]], the macro call inherits it and the table is recognised.
When calling macros using the [[widget|MacroCallWidget]], the parse mode will be inline (#3 and #4 above) unless it is written as an open tag with a following blank line (#5 above).

These examples have slightly different behavior. In the previous section, the macro calls were enclosed within list items. In these examples, the macro calls are at the top level:
<table><<wikitext-example-table-header>><tbody>
<<wikitext-example-table-row 1 "<<boringtable>>">>
<<wikitext-example-table-row 2 """<div>
<<boringtable>>
</div>
""">>
<<wikitext-example-table-row 3 "<$macrocall $name=boringtable/>">>
<<wikitext-example-table-row 4 "<$macrocall $name=boringtable></$macrocall>">>
<<wikitext-example-table-row 5 """<$macrocall $name=boringtable>
</$macrocall>""">>
</tbody></table>
Of these examples, only the two <<.wlink MacroCallWidget>> tags which are not followed by a blank line are parsed using [[inline mode|Inline Mode WikiText]].
