John Doe, ''Funky Book Title'' (Acme Co.){{#if:{{{end|}}}|, {{{start}}}&ndash;{{{end}}}.|{{#if:{{{start|}}}|, {{{start}}}.|{{#if:{{{pages|}}}|, {{{pages}}}.|.}}}}}}

This is demo code for the old-style templates which converts them to new-style without breaking them.

Send code to test it by calling:

<nowiki>{{FAIRWiki-Reference template code demo|start=5|end=10}}</nowiki>

A graphic comment on the code is available by clicking [[File:Page_number_template_(old_to_new_version)_code_documentation.PNG|here]].  Also, click edit to see more comments.

<!--This template demos how the old page number templates have been changed so old references still work, but new ones will also work.

The old style looked like this:

{{TPJS|start=5|end=10}}

This would give Teachings of the Prophet Joseph Smith, pp. 5-10.

There was also

{{TPJS1|start=5}}

Which would give Teachings of the Prophet Joseph Smith, pp. 5.

And sometimes

{{TPJS0}}

Which would give Teachings of the Prophet Joseph Smith.  [No page numbers.]

This is cumbersome.  The new system uses a more rational naming approach, as follows:

{{Book:Author:Title|pages=5-10}}

So, TPJS might be 

{{Book:Smith:Teachings of the Prophet Joseph Smith|pages=5-10}}

This edit allows all four templates to redirect to the same template, and still display properly.  So, the template:

a) checks to see if the argument {{{end}}} is sent.  If it is, assume this is {{TPJS}}, and display {{{start}}}&ndash;{{{end}}}.
b) if {{{end}}} does not exist, see if {{{start}}} exists.  If so, assume this is {{TPJS1}} and display {{{start}}} only.
c) if {{{end}}} and {{{start}}} do not exist, see if {{{pages}}} exists.  If so, this is the new style, and display {{{pages}}}.
d) if {{end}}}, {{{start}}}, and {{{pages}}} do not exist, assume the book is referred to without page number at all.-->
