'''IMPORTANT: THIS TEMPLATE IS NOT USED, the algoritm is implemented directly into [[Template:Lead]].'''

'''However, IT SHOULD NOT BE DELETED. It is useful for reference and to test new enhancements!'''
----

This template splits the parts of a Lead identifier. Examples are: “12 (2)” or "1*" or "1-". This lead identifier may combine:
<ol start="0">
<li>the couplet id common to all leads of a couplet “12”</li>
<li>the part identifying the alternative leads within a couplet:"*"”</li>
<li>and the "coming-from couplet or lead-id", called the backlink: “(2)”</li>
</ol>

The splitting is designed for the following cases:
* Number plus backlink in round parenthesis ("10 (2)")
* Number plus characters used to distinguish multiple leads in a couplet (like "2, 2*, 2**", "2, 2', 2''", ): Return 2 + *, etc.
** Note: unformatted apostrophe is converted to formatted apostrophe
* Number plus hyphen or ndash, like "2, 2-" (in contrast to the previous SplitNumber version, this now works exactly like with *)!
** Note: hyphen is converted to n-dash
* Number plus certain letter (for couplets with MANY leads), like "2 a, 2 b, 2 c"): Return 2 + a, etc.
*: Note: in this case, a blank must be present between the number and the letter. "1b" will not work!

It is intended to be used in combination with [[Template: Lead]].

The present implementation returns a semicolon-separated list of "before backlink", couplet id, alternative id and backlink.

In contrast to Lead/SplitNumber (the first version) this no longer handles:
* the display issues of the "1-"-case, where in the first lead ("1", "2" etc.) normally the "1", "2" are shown, but in the second lead ("1-", "2-" etc.) the number is REPLACED by the "-", rather than normally both being shown.

==USAGE examples==

* 123: actual = "{{#explode:{{Lead/SplitNumberV2 | 123 }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123 }}|$|2}}"; expected = "123 +"
* 123 (22): actual = "{{#explode:{{Lead/SplitNumberV2 | 123 (22) }}|$|1}} + ({{#explode:{{Lead/SplitNumberV2 | 123 (22) }}|$|3}})"; expected = "123 + (22)" -- full list is: {{Lead/SplitNumberV2 | 123 (22) }}
* 123*: actual = "{{#explode:{{Lead/SplitNumberV2 | 123* }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123* }}|$|2}}"; expected = "123 + *"
* 123**: actual = "{{#explode:{{Lead/SplitNumberV2 | 123** }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123** }}|$|2}}"; expected = "123 + **"
* 123***: actual = "{{#explode:{{Lead/SplitNumberV2 | 123*** }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123*** }}|$|2}}"; expected = "123 + ***"
* 123-: actual = "{{#explode:{{Lead/SplitNumberV2 | 123- }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123- }}|$|2}}"; expected = "123 + –"
* 123': actual = "{{#explode:{{Lead/SplitNumberV2 | 123' }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123' }}|$|2}}"; expected = "123 + ’"
* 123’’: actual = "{{#explode:{{Lead/SplitNumberV2 | 123’’ }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123’’ }}|$|2}}"; expected = "123 + ’’"
* 123 a: actual = "{{#explode:{{Lead/SplitNumberV2 | 123 a }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123 a }}|$|2}}"; expected = "123 + a"
* 123a: actual = "{{#explode:{{Lead/SplitNumberV2 | 123a }}|$|1}} + {{#explode:{{Lead/SplitNumberV2 | 123a }}|$|2}}"; expected = "123a + (EMPTY)" -- '''It is known that this does not work without a blank!'''
* Extra test with all parts returned: "{{Lead/SplitNumberV2 | 123* (2) }}" should result in: "123*$123$*$2".

: '''DEBUG NOTE:''' no longer handled in this template, needs to be done outside: SPECIAL HANDLING: lead number IS SUPPRESSED and the hyphen/dash swapped in. Note: Tried to replace hyphen with n-dash, plus the rest after it, but did not work: <nowiki>{{#replace: {{#sub:{{#var: leadIDMain}} |{{#pos:{{#var: leadIDMain}}|-}} |-|–}} }}</nowiki> So very simple instead just output – rather than replacing!
