Sandbox page for this template. The real page is at Template:SimpleNav.

TODO:

• Make it say "Volume" when on Volume page.
• Make it readable Better than before, at least...
• Make it easy to tell what the arguments are asking for
• Insert "beforename" and "aftername"
• Make it work even if there's something after the volume number aside from the usual (e.g. "Preview")
• Check whether this still works with * or ' in pagename
• Make it tolerant to pages with space after colon

Edit notes (use a text editor to interchange code with capital letters to improve readability):

In case of multiple layers of argument defaulting (such as in the case of {{{b|{{{before|}}} }}} ),
it's important to make sure there's no space immediately after the pipe,
or else it may insert an unwanted one (usually right after the page title's colon)

{{#rpos: {{#sub: {{FULLPAGENAME}} | 0 | -3 }} |   }}
produces the zero-based position of SPACE_BEFORE_LAST_WORD
*substring-ing -5 allows it to count out the potential space in "Chapter 1"
*also, it's important to use #rpos and not #pos here since the last space,
 or the first space from the /right/, is being looked for
*returns -1 if there is no space in title (this is the product of using #rpos and not #pos)

{{#sub: {{FULLPAGENAME}} | 0 | {{#pos: {{FULLPAGENAME}} | : }} }}
produces the string SERIES_TITLE
*title should not have a colon in it for this helper function to work
*returns FULLPAGENAME if string ":" doesn't exist in title,
 but /should/ be ignorable since it will return false on #ifexist

{{#sub: {{FULLPAGENAME}} | 0 | {{#pos: {{FULLPAGENAME}} | Volume }} }}
produces the string ALL_BEFORE_VOLUMES_V
*SERIES_TITLE should not have string "Volume" in it for this helper function to work
*SERIES_TITLE is not used because this retains the space after a colon, if there is one
*returns FULLPAGENAME if string "Volume" does not exist in title
 but /should/ be ignorable since this is only used in ifexist cases with colon taken out

{{#sub: {{FULLPAGENAME}} | {{#pos: {{FULLPAGENAME}} | Volume }} }}
produces the string ALL_AFTER_VOLUMES_V

{{#if: {{#pos: {{FULLPAGENAME}} | Volume }} | {{#expr: {{#pos: {{FULLPAGENAME}} | Volume }} +6 }} }}
produces the zero-based position AFTER_VOLUMES_E
*SERIES_TITLE should not have string "Volume" in it for this helper function to work
*returns nothing if "Volume" does not exist in pagename

{{#iferror: {{#expr: {{#sub: {{#sub: {{FULLPAGENAME}} | AFTER_VOLUMES_E }} | 0 | 3 }} + 0 }}
| {{#iferror: {{#expr: {{#sub: {{#sub: {{FULLPAGENAME}} | AFTER_VOLUMES_E }} | 0 | 2 }} + 0 }} }}
}}
produces the integer VOL_NUMBER
*returns nothing if "volume" does not exist in FULLPAGENAME, or if volume number is not a pure integer
*heavily reliant on the fact that NO VOLUME NUMBER GOES INTO THREE DIGITS
*(kinda hard to search&replace in notepad, break it into two segments, and remember to turn the line breaks into spaces)

{{#sub: {{#sub: {{FULLPAGENAME}} | AFTER_VOLUMES_E }} | {{#len: VOL_NUMBER }} }}
produces the string ALL_AFTER_VOLUME_NUMBER
*including the space immediately after, though this /should/ be ignorable
*returns FULLPAGENAME if "Volume" is not in the FULLPAGENAME
*returns all after Volume's e if volume number is not a pure integer

{{#sub: {{FULLPAGENAME}} | 0 | {{#pos: {{FULLPAGENAME}} | ALL_AFTER_VOLUME_NUMBER }} }}
produces the string ALL_UP_TO_VOLUME_NUMBER
*here, while parsing the space included in ALL_AFTER_VOLUME_NUMBER is /ignored/,
 which means there's a space included right after ALL_UP_TO_VOLUME_NUMBER instead,
 though again this /should/ be ignorable
*returns nothing if "volume" does not exist in FULLPAGENAME
*returns all before Volume's e if volume number is not a pure integer

{{#iferror:{{#expr:{{#sub:{{FULLPAGENAME}}|-2}}+0}}|{{#iferror:{{#expr:{{#sub:{{FULLPAGENAME}}|-1}}}}+0}}}}}}
produces the integer CHAPTER_NUM
*returns nothing if chapter number isn't the last thing in FULLPAGENAME
*works only if chapter number does not exceed three or more digits
