Examples/Parameter: format (example 4): Difference between revisions

This would list items in the ''File'' namespace, limited to a count of 3, formatted as a gallery using the <code>''{{tt|Startall''</code>}} and <code>''{{tt|Endall''</code>}} positionsarguments of the {{DPL|format}} syntax to specify gallery start and end. Note that when DPL3 parser function syntax is used to create a gallery, which uses tag syntax, the <code><</code> and <code>></code> characters must be escaped, so each is replaced by <code>«</code> and <code>»</code> respectively. The <code>''{{tt|Start''</code> position in the syntax specifies the <code>%PAGE%</code> (in this case the file page) followed by a line break <code><nowiki>\n</nowiki></code> to populate the MediaWiki gallery syntax needed. The <code>''Start''</code>}} and <code>''{{tt|End''</code>}} (empty,arguments notare required) parts of the syntax arethen applied to each result in the list, so the file page namenames isare fetched for each image, and put on a new line to complete the gallery statement. See [[mw:Help:Images#Gallery syntax|gallery syntax]] on MediaWiki Wiki for more information on gallery syntax.
