Warning:

This extension is incompatible with plans to parallelize parsing, as is intended by the use of Parsoid . Therefore, the future of this extension is uncertain, and it is expected to become incompatible with the standard MediaWiki parser within a few years. For further information, see T250963 and No support for sequential, in-order processing of extension tags .

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 {{#tag: in |}} magic word or the {{#counter:}} parser function after v0.6.0 of this extension.

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,...)

• <in />
• <ir />
• <ia />

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

See examples.

{{#counter: Counter name | type = Counter type | set = Number }}

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

Example 1

You can reset it using the parameter reset, and restart the count with the parameter begin

<ir />
<ir />
<ir />
<ir />
<ir />
<ir />
<ir />
<ir />
<ir />
<ir />

<ir reset=1 />
<ir />
<ir />
<ir />
<ir />
<ir />

<ia />
<ia />
<ia />

<ir begin=10 />
<ir />
<ir />
<ir />

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:

<ia reset=1 /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia /><ia />

abcdefghijklmnopqrstuvwxyz

Example 2

<ia>hello</ia>
<ia>world</ia>
<ia reset=1>goodbye</ia>
<ia>world</ia>
<ia begin=11>jupiter</ia>
<ia>jazz</ia>

<in>hello</in>
<in>world</in>
<in reset=1>goodbye</in>
<in>world</in>
<in begin=11>jupiter</in>
<in>jazz</in>

<ir>hello</ir>
<ir>world</ir>
<ir reset=1>goodbye</ir>
<ir>world</ir>
<ir begin=11>jupiter</ir>
<ir>jazz</ir>

Wikitext (since version 0.6.0)

{{#counter: ExampleCounter |type=numeral |set=9 }}
{{#counter: ExampleCounter }}
{{#counter: ExampleCounter }}

Result

9
10
11

Wikitext (since version 0.7.0)

{{#counter: list-with-levels |level prefix=: }} Start lev 1
{{#counter: }} Stay lev 1
{{#counter: |level=2 }} Jump to lev 2
{{#counter: }} Stay lev 2
{{#counter: |level=1 }} Drop to lev 1
{{#counter: |level=2 }} back to lev 2
{{#counter: |level=3 }} jump to lev 3

Result

1

2

1

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

1
