format | |||
This function allows one to format strings according to a template. This is a direct interface onto | |||
str.format() in Lua, and works like the C printf() function. | |||
For example: | |||
{{#invoke:string|format|page_%04d.html|65}} | |||
will produce the result | |||
page_0065.html | |||
Parameters | |||
1: The format template. See https://www.mediawiki.org/wiki/Extension:Scribunto/Lua_reference_manual#string.format | |||
2, 3, ...: Arguments to be inserted into the template. | |||
Note that leading and trailing whitespace is not removed from the arguments. | |||
