 | This is a documentation subpage for Template:Substring? It contains usage information, categories and other content that is not part of the original template page. |
Usage[edit source]
Provide two strings as unnamed parameters. If the second string is contained in the first (including, if they're the same string), returns the 1-indexed position of the second string within the first; otherwise, returns blank
Internals[edit source]
This is not meant to be part of a suite of string-manipulation tools; for general string manipulations, use {{evalx}}. Rather, this template is meant for a class of situations that may be quite common: a page contains a very large number of simple tests to distinguish separate cases, where all, or most, cases can be handled entirely with magic words; so that lots of server load can be saved by doing the test with Module:Substring? rather than Module:Wikilisp.
