Article titles for ships in navies that do not use a standardized prefix follow the title format:
<nationality> <ship type> <name> <(disambiguator)>
Article titles for ships may or may not be naval ships may follow the title format:
<name> <(disambiguator)>
where <(disambiguator)> may be some form of ship type, hull designator or pennant number, or year. This tool will
format ship names that contain a recognized ship type in <(disambiguator)>.
This list is used to <find ship> when the article title begins with a nationality. This is important because the tool
needs to know where the <ship type> ends and <name> begins so that it can properly place the italic markup. The search
will find an exact match (including case) for ship types that are 1 to 4 words long.
This list is also used to find ship type in <(disambiguator)>. The search is whole word; use the simplest form.
For example, because 'icebreaker' is defined, that ship type is sufficient to cause the tool to properly format:
Astrolabe (icebreaker)
Krassin (1917 icebreaker)
Taymyr (nuclear icebreaker)
Searches for ship type in <(disambiguator)> are whole word. When looking for 'ship', the tool will find
Auguste (ship)
Queen of Nations (clipper ship)
but will not find:
Sibir (steamship icebreaker) – the search for 'icebreaker' will
This is a list of ship types. When adding new ship types, do not be too specific: 'aircraft carrier' but not 'light aircraft carrier'
To add to this list the form is:
['ship type'] = true,
the trailing comma is important. At the time of this writing, a ship type may be one to four words, almost always lowercase.
Please insert ship types in alphabetical order.

Returns the size in words of ship type. Inputs are the fragment table, the number of elements in the fragment table,
and the number of words that make up nationality.
The number of fragments (words) in a ship name dictate the possible sizes of ship type. If nationality takes one fragment,
and ship type takes four fragments, then the minimum number of fragments in a composite ship name is:
5 = 1 (nationality) + 3 (ship type) + 1 (ship name) (same as 4 fragments (words) after nationality)
This function starts at the longest possible series of fragments that might be ship type. This order is important becuase
some ship types might begin with similar fragments: 'ship' and 'ship of the line'. Starting with the least possible
series of fragments (1) would find 'ship' and make 'of the line' part of the italicized name.
Returns 0 if there is no recognizable ship type.

This function applies correct styling to ship and ship-class names. These names are, for example, ship-article titles
used by templates {{navsource}}, {{Infobox ship begin}}, where the article title is to be rendered with proper
styling.
This function requires one argument:
|name= (required): a name is required; if missing or empty, this function returns an error message (may or may not be visible depending on where it is used)
used in {{infobox ship begin}} to provide a value for {{DISPLAYTITLE:}} and to provide a value for |infobox caption=
{{#invoke:WPSHIPS_utilities|ship_name_format|name={{PAGENAME}}}}
Optional arguments to support {{infobox ship begin}}:
|dab=none – displays ship name without parenthetical disambiguator; use when |infobox caption=nodab
|sclass=2 – for ship classes only; displays class name without italics (parameter name is loosely similar to {{slcass2}} which does the same thing); use when |infobox caption=class
|adj=off – for ship classes only; displays class name as a noun (no hyphen, no ship type); use when |infobox caption=class
Arguments are passed in a table.

This function is the external interface to do_ship_name_format().
The function requires one parameter:
|name= (required): a name is required; if missing or empty, this function returns an error message (may or may not be visible depending on where it is used)
used in {{infobox ship begin}} to provide a value for {{DISPLAYTITLE:}} and to provide a value for |infobox caption=

Optional parameters to support {{infobox ship begin}}:
|dab=none – displays ship name without parenthetical disambiguator; use when |infobox caption=nodab
|sclass=2 – for ship classes only; displays class name without italics (parameter name is loosely similar to {{slcass2}} which does the same thing); use when |infobox caption=class
|adj=off – for ship classes only; displays class name as a noun (no hyphen, no ship type); use when |infobox caption=class
Other optional parameters:
|showerrs=yes – marginally useful; can display error messages if the module invocation is not buried in a template
Values from the above parameters are placed in a table and that table passed as an argument in the call to do_ship_name_format().
do_ship_name_format() returns two strings: a name and an error message. If do_ship_name_format() could format the name, it returns the formatted name and
an empty string for the error message. If it could not format the name, do_ship_name_format() returns the original name and an error message.
Formatting of the error message, in response to |showerrs=yes is the responsibility of the calling function.

Assembles an error message, the original parameter value and, if appropriate a category. The error message precedes
the existing value of the parameter. If the first non-whitespace character in the parameter is a '*', set prefix to
a '*' and sep to '\n'. For line-break lists, set prefix to empty string and sep to '<br />'.
Category is appended to the end of the returned value only for pages in article space.
Inputs:
prefix – a string of characters that precede the error message span; typically '' and '*'
message – the error message to be displayed; goes inside the span
sep – a string of characters that separates the span from the parameter value; typically '\n' and '<br />'
param_val – the unmodified parameter value
showerrs – a boolean, true to display the error message text

Mediawiki:Common.css imposes limitations on plain, unbulleted lists. The template {{plainlist}} does not render this correctly:
{{plainlist|
*Item 1
*Item 2
**Item 2a
***Item 2a1
**Item 2b
*Item 3}}
The above renders without proper indents for items marked ** and ***.
If the list is not wrapped in {{plainlist}} then the above list is rendered with bullets which is contrary to the Infobox ship usage guide.
This code translates a bulleted list into an html unordered list:
<ul style="list-style:none none; margin:0;">
<li>Name 1</li>
<li>Name 2</li>
<ul style="list-style:none none">
<li>Subname 2a</li>
<ul style="list-style:none none">
<li>Subname 2a1</li>
</ul>
<li>Subname 2b</li>
</ul>
<li>Name 3</li>
</ul>
There are rules:
1. The parameter value must begin with a splat but may have leading and trailing whitespace.
2. Each list item after the first must begin on a new line just as is required by normal bulleted lists.
3. When adding a sublevel, the number of splats may increase by one and never more. This is illegal:
*item
***item
When any of these rules are violated, wpsu.unbulleted_list() returns the original text and adds the article
to Category:WPSHIPS:Infobox list errors. Error messaging in this function is somewhat sketchy so they are
disabled. After initial adoption, better error messaging could/should be implemented.
This function receives the content of one parameter:
