| 4 | * '#arraymaptemplate' is called as: |
| 5 | * |
| 6 | * {{#arraymaptemplate:value|template|delimiter|new_delimiter}} |
| 7 | * |
| 8 | * This function makes the same template call for every section of a |
| 9 | * delimited string; each such section, as dictated by the 'delimiter' |
| 10 | * value, is passed as a first parameter to the template specified. |
| 11 | * Finally, the transformed strings are joined together using the |
| 12 | * 'new_delimiter' string. Both 'delimiter' and 'new_delimiter' |
| 13 | * default to commas. |
| 14 | * |
| 15 | * Example: to take a semicolon-delimited list, and call a template |
| 16 | * named 'Beautify' on each element in the list, you could call the |
| 17 | * following: |
| 18 | * |
| 19 | * {{#arraymaptemplate:blue;red;yellow|Beautify|;|;}} |
