Extension:NumerAlpha

The NumerAlpha extension adds methods of inserting incrementing numbers, letters, and roman numerals into pages. You can reset the count at any moment or begin to a specified number.

First this extension was to supplement the Page Forms extension allowing to add a numbered table when you use the multiple option but you can also use it in templates by utilizing either the  magic word or the   parser function after v0.6.0 of this extension.

Usage
There are three forms:
 * a zero(s) padded number. (you can configure in the source code the length of your zero padded number. (0 = no zero padding)
 * Roman numeral (i, ii, iii, iv, etc.)
 * alphabetic (a,b,...,z,aa,ab,...,zz,...)

Tags
all of them in combination with reset=1 or begin=1

See examples.

Parser function
Available counter types are "numeral", "alpha" and "roman".

Tags
You can reset it using the parameter reset, and restart the count with the parameter begin
 * Example 1

That will be render like

i ii iii iv v vi vii viii ix

i ii iii iv v

a b c

x xi xii xiii

So it's easy to list the alphabet:

abcdefghijklmnopqrstuvwxyz

hello world goodbye world jupiter jazz
 * Example 2

hello world goodbye world</in> jupiter</in> jazz</in>

<ir>hello</ir> <ir>world</ir> goodbye</ir> <ir>world</ir> jupiter</ir> <ir>jazz</ir>

Parser function

 * Wikitext (since version 0.7.0)
 * Result
 * 1


 * 2


 * 1


 * 2


 * 3


 * 1


 * 1

This allows you to have hierarchical lists. Furthermore, if you add "format=outline" to the first #counter you can get output like:
 * 1


 * 2


 * 2.1


 * 2.2


 * 3


 * 3.1


 * 3.1.1
