This is the documentation page for Module:Highest archive number

Template:Module rating This module finds the highest archive number for a given set of numbered archive pages. The only input required is the prefix of the archive set. For example, for Talk:France/Archive 1, Talk:France/Archive 2, etc., the prefix would be "Talk:France/Archive ".

The module uses an exponential search algorithm, so it will make relatively few expensive function calls even for large numbers of archives. (The expensive function call is necessary to determine whether an individual archive exists.) For 1-10 archive pages, the module typically uses 4-6 expensive function calls; for 20-100 archives, it uses 6-12 calls; and for hundreds of archives, it uses 12-20 calls.

Because the module uses an exponential search, no gaps are allowed in the archive numbers; if there are any gaps, then the module may return the number of any archive page that exists where the following archive page does not exist. However, archive numbers do not have to start at 1; if they start at a higher number, you can specify this number in the start parameter.

Usage

From wikitext

From wikitext this module is usually used via the {{highest archive number}} template. However, it is also possible to use it directly from invoke with the syntax {{#invoke:highest archive number|main|prefix|start=start}}.

From Lua

Load the module with the following code:

<syntaxhighlight lang="lua"> local mHAN = require('Module:Highest archive number') </syntaxhighlight>

You can then use it like this:

<syntaxhighlight lang="lua"> mHAN._main(prefix, start) </syntaxhighlight>

The prefix variable is the prefix of the archive set.
